**Go 代码风格要求:**
- **MUST** 使用 `gofmt` 格式化所有代码
- **MUST** 遵循 [Effective Go](https://go.dev/doc/effective_go) 和 [Go Code Review Comments](https://go.dev/wiki/CodeReviewComments)
- 变量命名 **MUST** 使用 Go 风格：`userID`（不是 `userId`）、`HTTPServer`（不是 `HttpServer`）
- 缩写词 **MUST** 全部大写或全部小写：`URL`、`ID`、`HTTP`（导出）或 `url`、`id`、`http`（未导出）
- 包名 **MUST** 简短、小写、单数、无下划线：`user`、`order`、`pkg`（不是 `users`、`userService`、`user_service`）
- 接口命名 **SHOULD** 使用 `-er` 后缀：`Reader`、`Writer`、`Logger`（不是 `ILogger`、`LoggerInterface`）
**常量管理规范 (Constants Management):**
- 业务常量（状态码、类型枚举等）**MUST** 定义在 `pkg/constants/constants.go` 或按模块分文件
- Redis key **MUST** 使用函数生成，不允许硬编码字符串拼接
- Redis key 生成函数 **MUST** 遵循命名规范：`Redis{Module}{Purpose}Key(params...)`
- Redis key 格式 **MUST** 使用冒号分隔：`{module}:{purpose}:{identifier}`
- 示例：
```go
// 正确：使用常量和生成函数
constants.SIMStatusActive
constants.RedisSIMStatusKey(iccid) // 生成 "sim:status:{iccid}"
// 错误：硬编码和拼接
status := "active"
key := "sim:status:" + iccid
```
**Magic Numbers 和硬编码规则 (Magic Numbers and Hardcoding Rules):**
- **MUST NOT** 在代码中直接使用 magic numbers（未定义含义的数字字面量）
- **MUST NOT** 在代码中硬编码字符串字面量（URL、状态码、配置值、业务规则等）
- 当相同的字面量值在 **3 个或以上位置**使用时，**MUST** 提取为常量
- 已定义的常量 **MUST** 被使用，**MUST NOT** 重复硬编码相同的值
- 只允许在以下情况使用字面量：
- 语言特性：`nil`、`true`、`false`
- 数学常量：`0`、`1`、`-1`（用于循环、索引、比较等明确的上下文）
- 一次性使用的临时值（测试数据、日志消息等）
**正确的常量使用：**
```go
// pkg/constants/constants.go
const (
DefaultPageSize = 20
MaxPageSize = 100
MinPageSize = 1
SIMStatusActive = "active"
SIMStatusInactive = "inactive"
SIMStatusSuspended = "suspended"
OrderTypeRecharge = "recharge"
OrderTypeTransfer = "transfer"
)
// internal/handler/user.go
func (h *Handler) ListUsers(c *fiber.Ctx) error {
page := c.QueryInt("page", 1)
pageSize := c.QueryInt("page_size", constants.DefaultPageSize) // ✅ 使用常量
if pageSize > constants.MaxPageSize { // ✅ 使用常量
pageSize = constants.MaxPageSize
}
users, err := h.service.List(page, pageSize)
// ...
}
// internal/service/sim.go
func (s *Service) Activate(iccid string) error {
return s.store.UpdateStatus(iccid, constants.SIMStatusActive) // ✅ 使用常量
}
```
**错误的硬编码模式：**
```go
// ❌ 硬编码 magic number（在多处使用）
func ListUsers(c *fiber.Ctx) error {
pageSize := c.QueryInt("page_size", 20) // ❌ 硬编码 20
if pageSize > 100 { // ❌ 硬编码 100
pageSize = 100
}
// ...
}
func ListOrders(c *fiber.Ctx) error {
pageSize := c.QueryInt("page_size", 20) // ❌ 重复硬编码 20
// ...
}
// ❌ 硬编码字符串（在多处使用）
func ActivateSIM(iccid string) error {
return UpdateStatus(iccid, "active") // ❌ 硬编码 "active"
}
func IsSIMActive(sim *SIM) bool {
return sim.Status == "active" // ❌ 重复硬编码 "active"
}
// ❌ 已定义常量但不使用
// 常量已定义在 pkg/response/codes.go
func Success(c *fiber.Ctx, data any) error {
return c.JSON(Response{
Code: 0, // ❌ 应该使用 errors.CodeSuccess
Data: data,
})
}
```
**可接受的字面量使用：**
```go
// ✅ 语言特性和明确上下文的数字
if user == nil { // ✅ nil
return errors.New("user not found")
}
for i := 0; i < len(items); i++ { // ✅ 0, 1 用于循环
// ...
}
if count == 1 { // ✅ 1 用于比较
// 特殊处理单个元素
}
// ✅ 测试数据和日志消息
func TestUserCreate(t *testing.T) {
user := &User{
Name: "Test User", // ✅ 测试数据
Email: "test@example.com",
}
// ...
}
logger.Info("processing request", // ✅ 日志消息
zap.String("path", c.Path()),
zap.Int("status", 200))
```
**中文注释和输出规范 (Chinese Comments and Output Standards):**
本项目面向中文开发者，为提高代码可读性和维护效率，**SHOULD** 优先使用中文进行注释和输出。
- 代码注释（implementation comments）**SHOULD** 使用中文
- 日志消息（log messages）**SHOULD** 使用中文
- 用户可见的错误消息 **MUST** 使用中文（通过 `pkg/errors/` 的双语消息支持）
- 内部错误消息和调试日志 **SHOULD** 使用中文
- Go 文档注释（doc comments for exported APIs）**MAY** 使用英文以保持生态兼容性，但中文注释更佳
- 变量名、函数名、类型名 **MUST** 使用英文（遵循 Go 命名规范）
**正确的中文注释使用：**
```go
// GetUserByID 根据用户 ID 获取用户信息
// 如果用户不存在，返回 NotFoundError
func (s *Service) GetUserByID(ctx context.Context, id string) (*User, error) {
// 参数验证
if id == "" {
return nil, errors.New(errors.CodeInvalidParam, "用户 ID 不能为空")
}
// 从存储层获取用户
user, err := s.store.GetByID(ctx, id)
if err != nil {
s.logger.Error("获取用户失败",
zap.String("user_id", id),
zap.Error(err))
return nil, fmt.Errorf("获取用户失败: %w", err)
}
// 检查用户状态
if user.Status != constants.UserStatusActive {
s.logger.Warn("用户状态异常",
zap.String("user_id", id),
zap.String("status", user.Status))
}
return user, nil
}
// CreateOrder 创建新订单
func (s *Service) CreateOrder(ctx context.Context, req *CreateOrderRequest) (*Order, error) {
// 开启事务
tx := s.db.Begin()
defer func() {
if r := recover(); r != nil {
tx.Rollback()
s.logger.Error("创建订单时发生panic", zap.Any("panic", r))
}
}()
// 验证库存
if err := s.validateStock(ctx, req.ProductID, req.Quantity); err != nil {
tx.Rollback()
return nil, fmt.Errorf("库存验证失败: %w", err)
}
// 创建订单记录
order := &Order{
UserID: req.UserID,
ProductID: req.ProductID,
Quantity: req.Quantity,
Status: constants.OrderStatusPending,
}
if err := tx.Create(order).Error; err != nil {
tx.Rollback()
s.logger.Error("创建订单失败",
zap.String("user_id", req.UserID),
zap.Error(err))
return nil, err
}
tx.Commit()
s.logger.Info("订单创建成功",
zap.String("order_id", order.ID),
zap.String("user_id", req.UserID))
return order, nil
}
```
**正确的中文日志使用：**
```go
// 信息日志
logger.Info("服务启动成功",
zap.String("host", cfg.Server.Host),
zap.Int("port", cfg.Server.Port))
logger.Info("配置热重载成功",
zap.String("config_file", "config.yaml"),
zap.Time("reload_time", time.Now()))
// 警告日志
logger.Warn("Redis 连接延迟较高",
zap.Duration("latency", latency),
zap.String("threshold", "50ms"))
// 错误日志
logger.Error("数据库连接失败",
zap.String("host", cfg.DB.Host),
zap.Int("port", cfg.DB.Port),
zap.Error(err))
logger.Error("令牌验证失败",
zap.String("token", token[:10]+"..."),
zap.String("client_ip", clientIP),
zap.Error(err))
// 调试日志
logger.Debug("处理用户请求",
zap.String("request_id", requestID),
zap.String("method", c.Method()),
zap.String("path", c.Path()),
zap.String("user_id", userID))
```
**用户可见错误消息（双语支持）：**
```go
// pkg/errors/codes.go
var errorMessages = map[int]ErrorMessage{
CodeSuccess: {"Success", "成功"},
CodeInternalError: {"Internal server error", "内部服务器错误"},
CodeMissingToken: {"Missing authentication token", "缺失认证令牌"},
CodeInvalidToken: {"Invalid or expired token", "令牌无效或已过期"},
CodeTooManyRequests: {"Too many requests", "请求过于频繁"},
CodeAuthServiceUnavailable: {"Authentication service unavailable", "认证服务不可用"},
}
// 使用时根据语言返回对应消息
message := errors.GetMessage(code, "zh") // 返回中文消息
```
**错误的英文注释（不推荐）：**
```go
// ❌ 全英文注释（可读性较差，不便于中文团队维护）
// GetUserByID retrieves user information by user ID
// Returns NotFoundError if user does not exist
func (s *Service) GetUserByID(ctx context.Context, id string) (*User, error) {
// Validate parameters
if id == "" {
return nil, errors.New(errors.CodeInvalidParam, "用户 ID 不能为空")
}
// Fetch user from store
user, err := s.store.GetByID(ctx, id)
if err != nil {
s.logger.Error("Failed to get user", // ❌ 英文日志
zap.String("user_id", id),
zap.Error(err))
return nil, fmt.Errorf("failed to get user: %w", err)
}
return user, nil
}
```
**例外情况（可使用英文）：**
```go
// ✅ 导出的包级别文档注释可使用英文（生态兼容性）
// Package user provides user management functionality.
// It includes user CRUD operations, authentication, and authorization.
package user
// ✅ 导出的 API 文档注释可使用英文
// UserService provides user-related business logic operations.
type UserService struct {
store UserStorer
logger *zap.Logger
}
// ✅ 但内部实现注释应使用中文
func (s *UserService) Create(ctx context.Context, req *CreateUserRequest) (*User, error) {
// 验证用户输入
if err := req.Validate(); err != nil {
return nil, err
}
// 检查用户是否已存在
existing, _ := s.store.GetByEmail(ctx, req.Email)
if existing != nil {
return nil, errors.New(errors.CodeUserExists, "用户邮箱已存在")
}
// 创建用户记录
user := &User{
Name: req.Name,
Email: req.Email,
}
return s.store.Create(ctx, user)
}
```
**理由 (RATIONALE):** **理由 (RATIONALE):**
清晰的分层架构和代码组织使代码易于理解、测试和维护。统一的错误处理和响应格式提升 API 一致性和客户端集成体验。依赖注入模式便于单元测试和模块替换。 清晰的分层架构和代码组织使代码易于理解、测试和维护。统一的错误处理和响应格式提升 API 一致性和客户端集成体验。依赖注入模式便于单元测试和模块替换。集中管理常量和 Redis key 避免拼写错误、重复定义和命名不一致，提升代码可维护性和重构安全性。Redis key 统一管理便于监控、调试和缓存策略调整。遵循 Go 官方代码风格确保代码一致性和可读性。
避免硬编码和强制使用常量的规则能够：
1. **提高可维护性**：修改常量值只需改一处，不需要搜索所有硬编码位置
2. **减少错误**：避免手动输入错误（拼写错误、大小写错误）
3. **增强可读性**：`constants.MaxPageSize` 比 `100` 更能表达意图
4. **便于重构**：IDE 可以追踪常量使用，重命名时不会遗漏
5. **统一业务规则**：确保所有地方使用相同的业务规则值
6. "3 次规则"提供明确的阈值，避免过早优化，同时确保重复值被及时抽取

### VI. Go Idiomatic Design Principles (Go 语言惯用设计原则)
**核心理念：写 Go 味道的代码，不要写 Java 味道的代码**
#### 包组织 (Package Organization)
**MUST 遵循的原则：**
- 包结构 **MUST** 扁平化，避免深层嵌套（最多 2-3 层）
- 包 **MUST** 按功能组织，不是按层次组织
- 包名 **MUST** 描述功能，不是类型（`http` 不是 `httputils`、`handlers`）
**正确的 Go 风格：**
```
internal/
├── user/ # user 功能的所有代码
│ ├── handler.go # HTTP handlers
│ ├── service.go # 业务逻辑
│ ├── store.go # 数据访问
│ └── model.go # 数据模型
├── order/
│ ├── handler.go
│ ├── service.go
│ └── store.go
└── sim/
├── handler.go
├── service.go
└── store.go
```
**错误的 Java 风格（禁止）：**
```
internal/
├── handlers/
│ ├── user/
│ │ └── UserHandler.go # ❌ 类名式命名
│ └── order/
│ └── OrderHandler.go
├── services/
│ ├── user/
│ │ ├── IUserService.go # ❌ 接口前缀 I
│ │ └── UserServiceImpl.go # ❌ Impl 后缀
│ └── impls/ # ❌ 过度抽象
├── repositories/ # ❌ Repository 模式过度使用
│ └── interfaces/
└── models/
└── entities/
└── dto/ # ❌ 过度分层
```
#### 接口设计 (Interface Design)
**MUST 遵循的原则：**
- 接口 **MUST** 小而专注（1-3 个方法），不是大而全
- 接口 **SHOULD** 在使用方定义，不是实现方（依赖倒置）
- 接口命名 **SHOULD** 使用 `-er` 后缀：`Reader`、`Writer`、`Storer`
- **MUST NOT** 使用 `I` 前缀或 `Interface` 后缀
- **MUST NOT** 创建只有一个实现的接口（除非明确需要抽象）
**正确的 Go 风格：**
```go
// 小接口，在使用方定义
type UserStorer interface {
Create(ctx context.Context, user *User) error
GetByID(ctx context.Context, id string) (*User, error)
}
// 具体实现
type PostgresStore struct {
db *gorm.DB
}
func (s *PostgresStore) Create(ctx context.Context, user *User) error {
return s.db.WithContext(ctx).Create(user).Error
}
```
**错误的 Java 风格（禁止）：**
```go
// ❌ 大接口，方法过多
type IUserRepository interface {
Create(user *User) error
Update(user *User) error
Delete(id string) error
FindByID(id string) (*User, error)
FindByEmail(email string) (*User, error)
FindAll() ([]*User, error)
FindByStatus(status string) ([]*User, error)
Count() (int, error)
// ... 更多方法
}
// ❌ I 前缀
type IUserService interface {}
// ❌ 不必要的抽象层
type UserRepositoryImpl struct {} // 只有一个实现
```
#### 错误处理 (Error Handling)
**MUST 遵循的原则：**
- 错误 **MUST** 显式返回和检查，不使用异常（panic/recover）
- 错误处理 **MUST** 紧跟错误产生的代码
- **MUST** 使用 `errors.Is()` 和 `errors.As()` 检查错误类型
- **MUST** 使用 `fmt.Errorf()` 包装错误，保留错误链
- 自定义错误 **SHOULD** 实现 `error` 接口
- panic **MUST ONLY** 用于不可恢复的程序错误
**正确的 Go 风格：**
```go
func (s *Service) GetUser(ctx context.Context, id string) (*User, error) {
user, err := s.store.GetByID(ctx, id)
if err != nil {
// 包装错误，添加上下文
return nil, fmt.Errorf("get user by id %s: %w", id, err)
}
return user, nil
}
// 自定义错误类型
type NotFoundError struct {
Resource string
ID string
}
func (e *NotFoundError) Error() string {
return fmt.Sprintf("%s not found: %s", e.Resource, e.ID)
}
```
**错误的 Java 风格（禁止）：**
```go
// ❌ 使用 panic 代替错误返回
func GetUser(id string) *User {
user, err := db.Find(id)
if err != nil {
panic(err) // ❌ 不要这样做
}
return user
}
// ❌ try-catch 风格
func DoSomething() {
defer func() {
if r := recover(); r != nil { // ❌ 滥用 recover
log.Println("recovered:", r)
}
}()
// ...
}
// ❌ 异常类层次结构
type Exception interface { // ❌ 不需要
GetMessage() string
GetStackTrace() []string
}
type BusinessException struct {} // ❌ 过度设计
type ValidationException struct {} // ❌ 过度设计
```
#### 结构体和方法 (Structs and Methods)
**MUST 遵循的原则：**
- 结构体 **MUST** 简单直接，不是类（class）的替代品
- **MUST NOT** 为每个字段创建 getter/setter 方法
- **MUST** 直接访问导出的字段（大写开头）
- **MUST** 使用组合（composition）而不是继承（inheritance）
- 构造函数 **SHOULD** 命名为 `New` 或 `NewXxx`，返回具体类型
- **MUST NOT** 使用构造器模式（Builder Pattern）除非真正需要
**正确的 Go 风格：**
```go
// 简单结构体，导出字段直接访问
type User struct {
ID string
Name string
Email string
}
// 简单构造函数
func NewUser(name, email string) *User {
return &User{
ID: generateID(),
Name: name,
Email: email,
}
}
// 使用组合
type Service struct {
store UserStorer
logger *zap.Logger
}
func NewService(store UserStorer, logger *zap.Logger) *Service {
return &Service{
store: store,
logger: logger,
}
}
```
**错误的 Java 风格（禁止）：**
```go
// ❌ 私有字段 + getter/setter
type User struct {
id string // ❌ 不需要私有
name string
email string
}
func (u *User) GetID() string { return u.id } // ❌ 不需要
func (u *User) SetID(id string) { u.id = id } // ❌ 不需要
func (u *User) GetName() string { return u.name } // ❌ 不需要
func (u *User) SetName(name string) { u.name = name } // ❌ 不需要
// ❌ 构造器模式（不必要）
type UserBuilder struct {
user *User
}
func NewUserBuilder() *UserBuilder { // ❌ 过度设计
return &UserBuilder{user: &User{}}
}
func (b *UserBuilder) WithName(name string) *UserBuilder {
b.user.name = name
return b
}
func (b *UserBuilder) Build() *User {
return b.user
}
// ❌ 工厂模式（过度抽象）
type UserFactory interface { // ❌ 不需要
CreateUser(name string) *User
}
```
#### 并发模式 (Concurrency Patterns)
**MUST 遵循的原则：**
- **MUST** 使用 goroutines 和 channels，不是线程和锁（大多数情况）
- **MUST** 使用 `context.Context` 传递取消信号
- **MUST** 遵循"通过通信共享内存，不要通过共享内存通信"
- **SHOULD** 使用 `sync.WaitGroup` 等待 goroutines 完成
- **SHOULD** 使用 `sync.Once` 确保只执行一次
- **MUST NOT** 创建线程池类（Go 运行时已处理）
**正确的 Go 风格：**
```go
// 使用 goroutines 和 channels
func ProcessBatch(ctx context.Context, items []Item) error {
results := make(chan Result, len(items))
errors := make(chan error, len(items))
for _, item := range items {
go func(item Item) {
result, err := process(ctx, item)
if err != nil {
errors <- err
return
}
results <- result
}(item)
}
// 收集结果
for i := 0; i < len(items); i++ {
select {
case <-ctx.Done():
return ctx.Err()
case err := <-errors:
return err
case <-results:
// 处理结果
}
}
return nil
}
// 使用 sync.WaitGroup
func ProcessConcurrently(items []Item) {
var wg sync.WaitGroup
for _, item := range items {
wg.Add(1)
go func(item Item) {
defer wg.Done()
process(item)
}(item)
}
wg.Wait()
}
```
**错误的 Java 风格（禁止）：**
```go
// ❌ 线程池模式
type ThreadPool struct { // ❌ 不需要
workers int
taskQueue chan Task
wg sync.WaitGroup
}
func NewThreadPool(workers int) *ThreadPool { // ❌ Go 运行时已处理
return &ThreadPool{
workers: workers,
taskQueue: make(chan Task, 100),
}
}
// ❌ Future/Promise 模式（不需要单独实现）
type Future struct { // ❌ 直接使用 channel
result chan interface{}
err chan error
}
// ❌ 过度使用 mutex（应该用 channel）
type SafeMap struct { // ❌ 考虑使用 sync.Map 或 channel
mu sync.Mutex
data map[string]interface{}
}
func (m *SafeMap) Get(key string) interface{} {
m.mu.Lock()
defer m.mu.Unlock()
return m.data[key]
}
```
#### 命名约定 (Naming Conventions)
**MUST 遵循的原则：**
- 变量名 **MUST** 简短且符合上下文：
- 短作用域用短名字：`i`, `j`, `k` 用于循环
- 长作用域用描述性名字：`userRepository`, `configManager`
- 缩写词 **MUST** 保持一致的大小写：`URL`, `HTTP`, `ID`（不是 `Url`, `Http`, `Id`）
- **MUST NOT** 使用匈牙利命名法或类型前缀：`strName`, `arrUsers`（禁止）
- **MUST NOT** 使用下划线连接（除了测试和包名）：`user_service`（禁止，应该是 `userservice` 或 `UserService`）
- 方法接收者名称 **SHOULD** 使用 1-2 个字母的缩写，全文件保持一致
**正确的 Go 风格：**
```go
// 短作用域，短名字
for i, user := range users {
fmt.Println(i, user.Name)
}
// 长作用域，描述性名字
func ProcessUserRegistration(ctx context.Context, req *RegistrationRequest) error {
// ...
}
// 缩写词大小写一致
type UserAPI struct {
BaseURL string
APIKey string
UserID int64
}
// 方法接收者简短一致
type UserService struct {}
func (s *UserService) Create(user *User) error { // s 用于 service
return s.store.Create(user)
}
func (s *UserService) Update(user *User) error { // 保持一致使用 s
return s.store.Update(user)
}
```
**错误的 Java 风格（禁止）：**
```go
// ❌ 过长的变量名
func ProcessRegistration() {
userRegistrationRequest := &Request{} // ❌ 太长
userRegistrationValidator := NewValidator() // ❌ 太长
userRegistrationService := NewService() // ❌ 太长
}
// ❌ 匈牙利命名
strUserName := "John" // ❌
intUserAge := 25 // ❌
arrUserList := []User{} // ❌
// ❌ 下划线命名
type User_Service struct {} // ❌ 应该是 UserService
func Get_User_By_Id() {} // ❌ 应该是 GetUserByID
// ❌ 缩写词大小写不一致
type UserApi struct { // ❌ 应该是 UserAPI
BaseUrl string // ❌ 应该是 BaseURL
ApiKey string // ❌ 应该是 APIKey
UserId int64 // ❌ 应该是 UserID
}
// ❌ 方法接收者不一致或过长
func (userService *UserService) Create() {} // ❌ 太长
func (us *UserService) Update() {} // ❌ 与上面不一致
func (this *UserService) Delete() {} // ❌ 不要使用 this/self
```
#### 反模式清单 (Anti-Patterns to Avoid)
**严格禁止的 Java 风格模式：**
1. ❌ **过度抽象**：不需要的接口、工厂、构造器
2. ❌ **Getter/Setter**：直接访问导出字段
3. ❌ **继承层次**：使用组合，不是嵌入
4. ❌ **异常处理**：使用错误返回，不是 panic/recover
5. ❌ **单例模式**：使用包级别变量或 `sync.Once`
6. ❌ **线程池**：直接使用 goroutines
7. ❌ **深层包嵌套**：保持扁平结构
8. ❌ **类型前缀**：`IService`, `AbstractBase`, `ServiceImpl`
9. ❌ **Bean 风格**：不需要 POJO/JavaBean 模式
10. ❌ **过度 DI 框架**：简单直接的依赖注入
**理由 (RATIONALE):**
Go 语言的设计哲学强调简单性、直接性和实用性。Java 风格的模式（深层继承、过度抽象、复杂的设计模式）违背了 Go 的核心理念。Go 提供了更简单、更高效的方式来解决相同的问题：接口的隐式实现、结构体组合、显式错误处理、轻量级并发。遵循 Go 惯用法不仅使代码更地道，还能充分发挥 Go 的性能优势和简洁性。

# 君鸿卡管系统
## 系统简介
物联网卡 + 号卡全生命周期管理平台，支持代理商体系和分佣结算。
**技术栈**：Fiber + GORM + Viper + Zap + Lumberjack.v2 + Validator + sonic JSON + Asynq + PostgreSQL
**核心功能**：
- 物联网卡/号卡生命周期管理（开卡、激活、停机、复机、销户）
- 代理商层级管理和分佣结算
- 批量状态同步（卡状态、实名状态、流量使用情况）
- 与外部 Gateway 服务通过 RESTful API 交互

## 架构设计
### 分层架构
```
Handler (HTTP) → Service (业务逻辑) → Store (数据访问) → Model (数据模型)
```
### 双服务架构
- **API 服务**：处理 HTTP 请求，快速响应
- **Worker 服务**：处理异步任务（批量同步、分佣计算等），独立部署
### 核心模块
- **Service 层**：统一管理所有业务逻辑，支持跨模块调用
- **Store 层**：统一管理所有数据访问，支持事务
- **Task 层**：Asynq 任务处理器，支持定时任务和事件触发
---
## 开发规范
### 依赖注入
通过 `Service` 和 `Store` 结构体统一管理依赖：
```go
// 初始化
st := store.New(db)
svc := service.New(st, queueClient, logger)
// 使用
svc.SIM.Activate(...)
svc.Commission.Calculate(...)
```
### 事务处理
```go
store.Transaction(ctx, func(tx *store.Store) error {
tx.SIM.UpdateStatus(...)
tx.Commission.Create(...)
return nil
})
```
### 异步任务
- 高频任务：批量状态同步、流量同步、实名检查
- 业务任务：分佣计算、生命周期变更通知
- 任务优先级：critical > default > low
---
## 快速开始
### 配置
编辑 `config/config.yaml` 配置数据库和 Redis 连接
### 启动 API 服务
```bash
go run cmd/api/main.go
```
### 启动 Worker 服务
```bash
go run cmd/worker/main.go
```
---
## 设计原则
- **简单实用**：不过度设计，够用就好
- **直接实现**：避免不必要的接口抽象
- **统一管理**：依赖集中初始化，避免参数传递
- **职责分离**：API 和 Worker 独立部署，便于扩展
---
## 开发流程 (Speckit)
本项目使用 Speckit 规范化功能开发流程，确保代码质量、测试覆盖和架构一致性。
### 项目宪章 (Constitution)
项目遵循 `.specify/memory/constitution.md` 定义的核心原则：
1. **技术栈遵守**：严格使用 Fiber + GORM + Viper + Zap + Asynq，禁止原生调用快捷方式
2. **代码质量标准**：遵循 Handler → Service → Store → Model 分层架构
3. **测试标准**：70%+ 测试覆盖率，核心业务 90%+
4. **用户体验一致性**：统一 JSON 响应格式、RESTful API、双语错误消息
5. **性能要求**：API P95 < 200ms，P99 < 500ms，合理使用批量操作和异步任务
详细原则和规则请参阅宪章文档。
### Speckit 命令使用
#### 1. 创建功能规范
```bash
/speckit.specify "功能描述"
```
**用途**：从自然语言描述创建结构化的功能规范文档
**输出**：`specs/###-feature-name/spec.md`
**包含内容**：
- 用户故事和测试场景（按优先级排序 P1/P2/P3）
- 功能需求（FR-001, FR-002...）
- 技术需求（基于宪章自动生成）
- 成功标准
**示例**：
```bash
/speckit.specify "实现代理商分佣计算和结算功能，支持多级代理商分佣规则"
```
---
#### 2. 明确规范细节
```bash
/speckit.clarify
```

### 中间件详情
#### 1. Recover 中间件（fiber.Recover）
- **用途**：捕获 panic 并防止服务器崩溃
- **行为**：
- 捕获下游中间件/处理器中的任何 panic
- 将 panic 及堆栈跟踪记录到 `logs/app.log`
- 返回 HTTP 500 统一错误响应
- 服务器继续处理后续请求
- **始终激活**：是
#### 2. RequestID 中间件（自定义）
- **用途**：生成请求追踪的唯一标识符
- **行为**：
- 为每个请求生成 UUID v4
- 存储在上下文中：`c.Locals(constants.ContextKeyRequestID)`
- 添加 `X-Request-ID` 响应头
- 用于所有日志条目以进行关联
- **始终激活**：是
#### 3. Logger 中间件（自定义 Fiber 适配器）
- **用途**：记录所有 HTTP 请求和响应
- **行为**：
- 记录请求：方法、路径、IP、User-Agent、请求 ID
- 记录响应：状态码、耗时、用户 ID（如果已认证）
- 写入 `logs/access.log`（JSON 格式）
- 结构化字段便于解析和分析
- **始终激活**：是
- **日志格式**：包含字段的 JSON：timestamp、level、method、path、status、duration_ms、request_id、ip、user_agent、user_id
#### 4. KeyAuth 中间件（internal/middleware/auth.go）
- **用途**：使用 Token 验证对请求进行认证
- **行为**：
- 从 `token` 请求头提取 token
- 通过 Redis 验证 token（`auth:token:{token}`）
- 如果缺失/无效 token 返回 401
- 如果 Redis 不可用返回 503（fail-closed 策略）
- 成功时将用户 ID 存储在上下文中：`c.Locals(constants.ContextKeyUserID)`
- **配置**：`middleware.enable_auth`（默认：true）
- **跳过路由**：`/health`（健康检查绕过认证）
- **错误码**：
- 1001：缺失 token
- 1002：无效或过期 token
- 1004：认证服务不可用
#### 5. RateLimiter 中间件（internal/middleware/ratelimit.go）
- **用途**：通过限制请求速率保护 API 免受滥用
- **行为**：
- 按客户端 IP 地址追踪请求
- 执行限制：`expiration` 时间窗口内 `max` 个请求
- 如果超过限制返回 429
- 每个 IP 地址独立计数器
- **配置**：`middleware.enable_rate_limiter`（默认：false）
- **存储选项**：
- `memory`：内存存储（单服务器，重启后重置）
- `redis`：基于 Redis（分布式，持久化）
- **错误码**：1003（请求过于频繁）
#### 6. 路由处理器
- **用途**：执行端点的业务逻辑
- **可用上下文数据**：
- 请求 ID：`c.Locals(constants.ContextKeyRequestID)`
- 用户 ID：`c.Locals(constants.ContextKeyUserID)`（如果已认证）
- 标准 Fiber 上下文方法：`c.Params()`、`c.Query()`、`c.Body()` 等
### 中间件注册（cmd/api/main.go）
```go
// 核心中间件（始终激活）
app.Use(recover.New())
app.Use(addRequestID())
app.Use(loggerMiddleware())
// 可选：认证中间件
if config.GetConfig().Middleware.EnableAuth {
tokenValidator := validator.NewTokenValidator(rdb, logger.GetAppLogger())
app.Use(middleware.KeyAuth(tokenValidator, logger.GetAppLogger()))
}
// 可选：限流中间件
if config.GetConfig().Middleware.EnableRateLimiter {
var storage fiber.Storage = nil
if config.GetConfig().Middleware.RateLimiter.Storage == "redis" {
storage = redisStorage // 使用 Redis 存储
}
app.Use(middleware.RateLimiter(
config.GetConfig().Middleware.RateLimiter.Max,
config.GetConfig().Middleware.RateLimiter.Expiration,
storage,
))
}
// 路由
app.Get("/health", healthHandler)
app.Get("/api/v1/users", listUsersHandler)
```
### 请求流程示例
**场景**：已启用所有中间件的 `/api/v1/users` 认证请求
```
1. 请求到达：GET /api/v1/users
请求头：token: abc123
2. Recover 中间件：准备捕获 panic
→ 传递到下一个中间件
3. RequestID 中间件：生成 UUID
→ 设置上下文：request_id = "550e8400-e29b-41d4-a716-446655440000"
→ 传递到下一个中间件
4. Logger 中间件：记录请求开始
→ 日志：{"method":"GET", "path":"/api/v1/users", "request_id":"550e8400-..."}
→ 传递到下一个中间件
5. KeyAuth 中间件：验证 token
→ 检查 Redis：GET "auth:token:abc123" → "user-789"
→ 设置上下文：user_id = "user-789"
→ 传递到下一个中间件
6. RateLimiter 中间件：检查限流
→ 检查计数器：GET "rate_limit:127.0.0.1" → "5"（低于限制 100）
→ 增加计数器：INCR "rate_limit:127.0.0.1" → "6"
→ 传递到下一个中间件
7. 处理器执行：listUsersHandler()
→ 从上下文获取 user_id："user-789"
→ 从数据库获取用户
→ 返回响应：{"code":0, "data":[...], "msg":"success"}
8. Logger 中间件：记录响应
→ 日志：{"status":200, "duration_ms":23.45, "user_id":"user-789"}
9. RequestID 中间件：添加响应头
→ 响应头：X-Request-ID: 550e8400-e29b-41d4-a716-446655440000
10. 响应发送给客户端
```
### 中间件中的错误处理
如果任何中间件返回错误，链停止并发送错误响应：
```
请求 → Recover → RequestID → Logger → [KeyAuth 失败] ✗
↓
返回 401
（不执行 RateLimiter 和 Handler）
```
示例：缺失 token
```
KeyAuth：Token 缺失
→ 返回 response.Error(c, 401, 1001, "缺失认证令牌")
→ Logger 记录：{"status":401, "duration_ms":1.23}
→ RequestID 添加响应头
→ 发送响应
```
## 配置
### 环境特定配置
设置 `CONFIG_ENV` 环境变量以加载特定配置：
```bash
# 开发环境（config.dev.yaml）
export CONFIG_ENV=dev
# 预发布环境（config.staging.yaml）
export CONFIG_ENV=staging
# 生产环境（config.prod.yaml）
export CONFIG_ENV=prod
# 默认配置（config.yaml）
# 不设置 CONFIG_ENV
```
### 配置热重载
配置更改在 5 秒内自动检测并应用，无需重启服务器：
- **监控文件**：所有 `configs/*.yaml` 文件
- **检测**：使用 fsnotify 监视文件更改
- **验证**：应用前验证新配置
- **行为**：
- 有效更改：立即应用，记录到 `logs/app.log`
- 无效更改：拒绝，服务器继续使用先前配置
- **原子性**：使用 `sync/atomic` 进行线程安全的配置更新
**示例**：
```bash
# 在服务器运行时编辑配置
vim configs/config.yaml
# 将 logging.level 从 "info" 改为 "debug"
# 检查日志（5 秒内）
tail -f logs/app.log | jq .
# {"level":"info","message":"配置文件已更改","file":"configs/config.yaml"}
# {"level":"info","message":"配置重新加载成功"}
```
## 测试
### 运行所有测试
```bash
# 运行所有单元和集成测试
go test ./...
# 带覆盖率运行
go test -cover ./...
# 详细输出运行
go test -v ./...
```
### 运行特定测试套件
```bash
# 仅单元测试
go test ./pkg/...
# 仅集成测试
go test ./tests/integration/...
# 特定测试
go test -v ./internal/middleware -run TestKeyAuth
```
### 集成测试
集成测试需要 Redis 运行：
```bash
# 启动 Redis
redis-server
# 运行集成测试
go test -v ./tests/integration/...
```
如果 Redis 不可用，测试自动跳过。
## 架构设计
### 分层架构
```
Handler (HTTP) → Service (业务逻辑) → Store (数据访问) → Model (数据模型)
```
### 双服务架构
- **API 服务**：处理 HTTP 请求，快速响应
- **Worker 服务**：处理异步任务（批量同步、分佣计算等），独立部署
### 核心模块
- **Service 层**：统一管理所有业务逻辑，支持跨模块调用
- **Store 层**：统一管理所有数据访问，支持事务
- **Task 层**：Asynq 任务处理器，支持定时任务和事件触发
## 开发规范
### 依赖注入
通过 `Service` 和 `Store` 结构体统一管理依赖：
```go
// 初始化
st := store.New(db)
svc := service.New(st, queueClient, logger)
// 使用
svc.SIM.Activate(...)
svc.Commission.Calculate(...)
```
### 事务处理
```go
store.Transaction(ctx, func(tx *store.Store) error {
tx.SIM.UpdateStatus(...)
tx.Commission.Create(...)
return nil
})
```
### 异步任务
- 高频任务：批量状态同步、流量同步、实名检查
- 业务任务：分佣计算、生命周期变更通知
- 任务优先级：critical > default > low
### 常量和 Redis Key 管理
所有常量统一在 `pkg/constants/` 目录管理：
```go
// 业务常量
constants.SIMStatusActive
constants.SIMStatusInactive
// Redis Key 管理（统一使用 Key 生成函数）
constants.RedisSIMStatusKey(iccid) // sim:status:{iccid}
constants.RedisAgentCommissionKey(agentID) // agent:commission:{agentID}
constants.RedisTaskLockKey(taskName) // task:lock:{taskName}
constants.RedisAuthTokenKey(token) // auth:token:{token}
// 使用示例
key := constants.RedisSIMStatusKey("898600...")
rdb.Set(ctx, key, status, time.Hour)
```

## 开发流程（Speckit）
本项目使用 Speckit 规范化功能开发流程，确保代码质量、测试覆盖和架构一致性。
### 项目宪章
项目遵循 `.specify/memory/constitution.md` 定义的核心原则：
1. **技术栈遵守**：严格使用 Fiber + GORM + Viper + Zap + Asynq，禁止原生调用快捷方式
2. **代码质量标准**：遵循 Handler → Service → Store → Model 分层架构
3. **测试标准**：70%+ 测试覆盖率，核心业务 90%+
4. **用户体验一致性**：统一 JSON 响应格式、RESTful API、双语错误消息
5. **性能要求**：API P95 < 200ms，P99 < 500ms，合理使用批量操作和异步任务
详细原则和规则请参阅宪章文档。
### Speckit 命令
```bash
# 创建功能规范
/speckit.specify "功能描述"
# 明确规范细节
/speckit.clarify
# 生成实现计划
/speckit.plan
# 生成任务列表
/speckit.tasks
# 执行实现
/speckit.implement
# 一致性分析
/speckit.analyze
# 生成自定义检查清单
/speckit.checklist "检查项要求"
# 更新项目宪章
/speckit.constitution "宪章更新说明"
```
## 设计原则
- **简单实用**：不过度设计，够用就好
- **直接实现**：避免不必要的接口抽象
- **统一管理**：依赖集中初始化，避免参数传递
- **职责分离**：API 和 Worker 独立部署，便于扩展

## 🎯 架构亮点
### 1. 中间件执行顺序设计
```
请求
→ Recover（捕获 Panic，保护服务）
→ RequestID（生成唯一 ID，便于追踪）
→ Logger（记录访问日志）
→ Compress（压缩响应）
→ KeyAuth（令牌验证，可选）
→ RateLimiter（限流保护，可选）
→ Handler（业务逻辑）
→ 响应
```
**设计原则**:
- Recover 必须第一个（捕获所有 Panic）
- RequestID 在 Logger 之前（日志需要请求 ID）
- KeyAuth 在 RateLimiter 之前（先验证再限流）
### 2. Fail-Closed 安全策略
当 Redis 不可用时：
- 拒绝所有认证请求（返回 503）
- 保护系统安全，防止未授权访问
- 快速失败（8.3 μs），不占用资源
### 3. 配置热重载设计
- 使用 `atomic.Value` 实现无锁读取
- 使用 `fsnotify` 监听配置文件变化
- 读取性能接近 CPU 缓存速度（0.58 ns）
- 不影响正在处理的请求
### 4. 统一响应格式
```json
{
"code": 0,
"data": {...},
"msg": "success",
"timestamp": "2025-11-11T16:30:00+08:00"
}
```
**优势**:
- 客户端解析简单
- 支持国际化错误消息
- 时间戳便于调试和追踪
### 5. Redis Key 统一管理
```go
// pkg/constants/redis.go
func RedisAuthTokenKey(token string) string {
return fmt.Sprintf("auth:token:%s", token)
}
func RedisRateLimitKey(ip string) string {
return fmt.Sprintf("ratelimit:%s", ip)
}
```
**优势**:
- 避免硬编码字符串
- 统一命名规范
- 易于重构和维护
- 防止拼写错误

## 🚀 性能表现
### 基准测试结果
| 操作 | 延迟 | 吞吐量 | 内存分配 |
|------|------|--------|----------|
| 令牌验证（有效） | 17.5 μs | 58,954 ops/s | 9.5 KB/op |
| 令牌验证（无效） | 17.3 μs | 66,168 ops/s | 9.7 KB/op |
| Fail-closed | 8.3 μs | 134,738 ops/s | 4.8 KB/op |
| 响应序列化 | 1.1 μs | 1,073,145 ops/s | 2.0 KB/op |
| 配置访问 | 0.58 ns | 1,700,000,000 ops/s | 0 B/op |
### 端到端性能估算
假设一个典型的受保护 API 请求：
- 令牌验证: 17.5 μs
- 业务逻辑: 5.0 μs
- 响应序列化: 1.1 μs
- 其他中间件: ~4 μs
- **总计**: ~27.6 μs
**预期延迟**:
- P50: ~30 μs
- P95: ~50 μs
- P99: ~100 μs
**预期吞吐量**:
- 单核: ~58,954 req/s（受限于令牌验证）
- M1 Pro (8核): ~471,632 req/s（理论峰值）
- 生产环境（单实例）: 10,000 - 50,000 req/s

**优化方案**:
```go
// 方案 A: 移除每次请求的 Ping（信任 Redis 连接）
// 性能提升：~50%（8.5 μs/op）
// 风险：Fail-closed 策略失效
// 方案 B: 使用本地缓存（短期 TTL）
// 性能提升：~90%（1-2 μs/op）
// 风险：令牌失效延迟（可接受：5-10秒）
```
**建议**: 当前性能已足够，暂不优化 ✅
#### 2. 响应序列化优化（可选）
**当前**: 使用 bytedance/sonic（已是最快的 Go JSON 库之一）
**优化方案**:
```go
// 方案 A: 使用 Protocol Buffers 或 MessagePack
// 性能提升：~30-50%
// 代价：客户端需要支持
// 方案 B: 启用 HTTP/2 Server Push
// 性能提升：减少往返延迟
```
**建议**: 当前性能已足够，暂不优化 ✅

- ⚠️ **已修复**：日志中泄露令牌信息（pkg/validator/token.go:56）
- ✅ **Redis 连接安全**：生产环境使用环境变量存储密码
- ⚠️ **需要行动**：升级 Go 至 1.25.2+ 以修复 5 个标准库漏洞
- ℹ️ **可接受风险**：开发环境配置文件中存在硬编码密码（团队决策）
---
## T109: 认证实现审查
### ✅ 安全优势
1. **Fail-closed 策略实现正确** (pkg/validator/token.go:28-34)
```go
if err := v.redis.Ping(ctx).Err(); err != nil {
return "", errors.ErrRedisUnavailable // Redis 不可用时拒绝所有请求
}
```
- Redis 不可用时拒绝所有请求 ✓
- 返回 503 Service Unavailable ✓
2. **令牌验证逻辑安全**
- 使用 Redis GET 验证令牌存在性 ✓
- 验证用户 ID 非空 ✓
- 超时设置合理（50ms）防止慢速攻击 ✓
3. **上下文隔离**
- 用户 ID 安全存储在 Fiber 上下文中 ✓
- 使用常量键避免冲突 ✓
4. **错误处理映射正确**

## T110: Redis 连接安全审查
### ✅ 安全措施
1. **密码管理**
- 生产环境：使用 `${REDIS_PASSWORD}` 环境变量 ✓
- 预发布环境：使用 `${REDIS_PASSWORD}` 环境变量 ✓
- 开发环境：硬编码密码（团队决策，便于小团队协作）
2. **连接配置**
- 连接池大小合理配置（防止连接耗尽攻击）✓
- 超时设置完善：
- dial_timeout: 5s
- read_timeout: 3s
- write_timeout: 3s
### ⚠️ 改进建议（非阻塞）
1. **TLS 加密**
- 当前状态：未配置 TLS
- 建议：生产环境启用 Redis TLS 连接
- 优先级：中等（如果 Redis 部署在私有网络中，优先级可降低）
2. **网络隔离**
- 确保 Redis 不对公网开放
- 使用防火墙规则限制访问
**结论**: Redis 连接配置安全，密码管理符合行业标准 ✅
---
## T111: 日志敏感信息审查
### ⚠️ 发现的问题（已修复）
**问题**: pkg/validator/token.go:56 记录了完整的 Redis key（包含令牌）
```go
// 修复前（不安全）
v.logger.Error("Redis 获取失败",
zap.Error(err),
zap.String("token_key", constants.RedisAuthTokenKey(token)), // ❌ 泄露令牌
)
// 修复后（安全）
v.logger.Error("Redis 获取失败",
zap.Error(err),
// 注意：不记录完整的 token_key 以避免泄露令牌
)
```
**影响**: 令牌可能被记录到日志文件，存在泄露风险
**修复**: 已移除 token_key 记录
**验证**: ✅ 已通过代码审查确认
### ✅ 其他日志记录安全
1. **访问日志不记录敏感信息** (pkg/logger/middleware.go)
- 记录内容：method, path, status, duration, request_id, ip, user_agent, user_id
- ✓ 不记录 token header
- ✓ 不记录请求 body
- ✓ 不记录密码字段
2. **认证失败日志安全** (internal/middleware/auth.go)
- 只记录 request_id 和错误类型
- ✓ 不记录令牌值
3. **应用日志安全**
- Redis 连接成功：只记录地址，不记录密码 ✓
- 配置热重载：只记录文件名 ✓
**结论**: 日志记录安全，无敏感信息泄露 ✅
---
## T112: 配置文件安全审查
### ✅ 安全措施
1. **gitignore 配置**
```
.env
.env.*
!.env.example
config/local.yaml
configs/local.yaml
```
- 环境变量文件已忽略 ✓
- 本地配置文件已忽略 ✓
2. **密码管理**
- **config.prod.yaml**: `password: "${REDIS_PASSWORD}"` ✅
- **config.staging.yaml**: `password: "${REDIS_PASSWORD}"` ✅
- **config.dev.yaml**: `password: "cpNbWtAaqgo1YJmbMp3h"`（硬编码）
- **config.yaml**: `password: "cpNbWtAaqgo1YJmbMp3h"`（硬编码）
### ℹ️ 可接受风险
开发环境配置文件中存在硬编码密码，这是团队的有意决策：
- **理由**: 小团队协作，简化新成员上手流程
- **风险评估**: 低（仅开发环境使用，生产环境使用环境变量）
- **缓解措施**:
- 生产环境强制使用环境变量
- 开发环境 Redis 不对公网开放
- 定期轮换开发环境密码（建议）
**结论**: 配置文件管理符合团队需求，生产环境安全 ✅
---
## T113: 依赖项漏洞审查
### ⚠️ 发现的漏洞（需要升级）

- [x] No implementation details (languages, frameworks, APIs)
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed
## Requirement Completeness
- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified
- [x] Scope is clearly bounded
- [x] Dependencies and assumptions identified
## Feature Readiness
- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification
## Validation Results
### Content Quality Assessment
✅ **PASS**: The specification focuses on user value and business outcomes without implementation details. While technical components (Viper, Zap, Redis) are mentioned in the functional requirements, they describe **what capabilities** the system must provide (configuration management, structured logging, token validation) rather than **how to implement** them. The Technical Requirements section appropriately references the project constitution's technology choices.
✅ **PASS**: The specification is written from a business/operations perspective with user stories framed around administrator needs, API consumer expectations, and system reliability outcomes.
✅ **PASS**: All mandatory sections (User Scenarios, Requirements, Success Criteria) are completed with detailed content.
### Requirement Completeness Assessment
✅ **PASS**: No [NEEDS CLARIFICATION] markers present. All requirements are concrete and specific.
✅ **PASS**: All functional requirements are testable with clear expected behaviors (e.g., "detect changes within 5 seconds", "return HTTP 401 with specific error format").
✅ **PASS**: Success criteria include specific measurable metrics:
- Time-based: "within 5 seconds", "within 50ms", "within 100ms"
- Percentage-based: "100% consistency", "100% of HTTP requests"
- Behavior-based: "automatically rotate when reaching configured size limits"
✅ **PASS**: Success criteria are technology-agnostic, focusing on user/system outcomes (e.g., "System administrators can modify configuration and see it applied" rather than "Viper watches config files").
✅ **PASS**: All user stories include detailed acceptance scenarios in Given-When-Then format.
✅ **PASS**: Edge cases section covers 7 different failure/boundary scenarios with expected behaviors.
✅ **PASS**: Scope is clearly bounded through prioritized user stories (P1, P2, P3) and explicitly states rate limiting is "implemented but disabled by default".
✅ **PASS**: Dependencies identified through Technical Requirements section referencing constitution standards, and implicit dependencies on Redis for token validation.
### Feature Readiness Assessment
✅ **PASS**: Each of the 22 functional requirements maps to acceptance scenarios in user stories and success criteria.
✅ **PASS**: Seven prioritized user stories cover the complete feature set from foundational (configuration, logging) to security (authentication) to optional (rate limiting).
✅ **PASS**: Ten success criteria provide measurable validation for all major functional areas.
✅ **PASS**: Technical Requirements section appropriately references existing project standards rather than introducing new implementation details.
## Overall Assessment
**STATUS**: ✅ **READY FOR PLANNING**
All checklist items pass validation. The specification is complete, testable, and ready for the `/speckit.plan` phase.
## Notes
- The specification successfully balances business requirements with project constitution compliance
- User stories are well-prioritized with clear independent test criteria
- Edge cases demonstrate thorough consideration of failure scenarios
- Success criteria provide clear acceptance thresholds without prescribing implementation approaches

Card Management System API with unified response format and middleware integration.
## Unified Response Format
All API endpoints return responses in the following unified format:
```json
{
"code": 0,
"data": {},
"msg": "success",
"timestamp": "2025-11-10T15:30:45Z"
}
```
## Error Codes
| Code | HTTP Status | Description (EN) | Description (ZH) |
|------|-------------|------------------|------------------|
| 0 | 200 | Success | 成功 |
| 1000 | 500 | Internal server error | 内部服务器错误 |
| 1001 | 401 | Missing authentication token | 缺失认证令牌 |
| 1002 | 401 | Invalid or expired token | 令牌无效或已过期 |
| 1003 | 429 | Too many requests | 请求过于频繁 |
| 1004 | 503 | Authentication service unavailable | 认证服务不可用 |
## Authentication
Protected endpoints require a valid authentication token in the request header:
```
token: your-auth-token-here
```
## Request Tracing
Every response includes an `X-Request-ID` header containing a unique UUID v4 identifier for request tracing and correlation.

# Data Model: Fiber Middleware Integration
**Feature**: 001-fiber-middleware-integration
**Date**: 2025-11-10
**Phase**: 1 - Design & Contracts
## Overview
This document defines the data structures, entities, and models used in the middleware integration feature. All structures follow Go idiomatic design principles with simple, flat structures and no Java-style patterns.
---
## 1. Configuration Model
### Config Structure
**File**: `pkg/config/config.go`
```go
// Config represents the application configuration
type Config struct {
Server ServerConfig `mapstructure:"server"`
Redis RedisConfig `mapstructure:"redis"`
Logging LoggingConfig `mapstructure:"logging"`
Middleware MiddlewareConfig `mapstructure:"middleware"`
}
// ServerConfig contains HTTP server settings
type ServerConfig struct {
Address string `mapstructure:"address"` // e.g., ":3000"
ReadTimeout time.Duration `mapstructure:"read_timeout"` // e.g., "10s"
WriteTimeout time.Duration `mapstructure:"write_timeout"` // e.g., "10s"
ShutdownTimeout time.Duration `mapstructure:"shutdown_timeout"` // e.g., "30s"
Prefork bool `mapstructure:"prefork"` // Multi-process mode
}
// RedisConfig contains Redis connection settings
type RedisConfig struct {
Address string `mapstructure:"address"` // e.g., "localhost:6379"
Password string `mapstructure:"password"` // Leave empty if no auth
DB int `mapstructure:"db"` // Database number (0-15)
PoolSize int `mapstructure:"pool_size"` // Max connections
MinIdleConns int `mapstructure:"min_idle_conns"` // Keep-alive connections
DialTimeout time.Duration `mapstructure:"dial_timeout"` // e.g., "5s"
ReadTimeout time.Duration `mapstructure:"read_timeout"` // e.g., "3s"
WriteTimeout time.Duration `mapstructure:"write_timeout"` // e.g., "3s"
}
// LoggingConfig contains logging settings
type LoggingConfig struct {
Level string `mapstructure:"level"` // debug, info, warn, error
Development bool `mapstructure:"development"` // Enable dev mode (pretty print)
AppLog LogRotationConfig `mapstructure:"app_log"` // Application log settings
AccessLog LogRotationConfig `mapstructure:"access_log"` // HTTP access log settings
}
// LogRotationConfig contains log rotation settings for Lumberjack
type LogRotationConfig struct {
Filename string `mapstructure:"filename"` // Log file path
MaxSize int `mapstructure:"max_size"` // Max size in MB before rotation
MaxBackups int `mapstructure:"max_backups"` // Max number of old files to keep
MaxAge int `mapstructure:"max_age"` // Max days to retain old files
Compress bool `mapstructure:"compress"` // Compress rotated files
}
// MiddlewareConfig contains middleware settings
type MiddlewareConfig struct {
EnableAuth bool `mapstructure:"enable_auth"` // Enable keyauth middleware
EnableRateLimiter bool `mapstructure:"enable_rate_limiter"` // Enable limiter (default: false)
RateLimiter RateLimiterConfig `mapstructure:"rate_limiter"` // Rate limiter settings
}
// RateLimiterConfig contains rate limiter settings
type RateLimiterConfig struct {
Max int `mapstructure:"max"` // Max requests per window
Expiration time.Duration `mapstructure:"expiration"` // Time window (e.g., "1m")
Storage string `mapstructure:"storage"` // "memory" or "redis"
}
// Validate validates configuration values
func (c *Config) Validate() error {
if c.Server.Address == "" {
return errors.New("server address cannot be empty")
}
if c.Server.ReadTimeout <= 0 {
return errors.New("server read timeout must be positive")
}
if c.Redis.Address == "" {
return errors.New("redis address cannot be empty")
}
if c.Redis.PoolSize <= 0 {
return errors.New("redis pool size must be positive")
}
if c.Logging.AppLog.Filename == "" {
return errors.New("app log filename cannot be empty")
}
if c.Logging.AccessLog.Filename == "" {
return errors.New("access log filename cannot be empty")
}
if c.Middleware.RateLimiter.Max <= 0 {
c.Middleware.RateLimiter.Max = 100 // Default
}
return nil
}
```
**Example YAML Configuration** (`configs/config.yaml`):
```yaml
server:
address: ":3000"
read_timeout: "10s"
write_timeout: "10s"
shutdown_timeout: "30s"
prefork: false
redis:
address: "localhost:6379"
password: ""
db: 0
pool_size: 10
min_idle_conns: 5
dial_timeout: "5s"
read_timeout: "3s"
write_timeout: "3s"
logging:
level: "info"
development: false
app_log:
filename: "logs/app.log"
max_size: 100 # MB
max_backups: 30
max_age: 30 # days
compress: true
access_log:
filename: "logs/access.log"
max_size: 500 # MB
max_backups: 90
max_age: 90 # days
compress: true
middleware:
enable_auth: true
enable_rate_limiter: false # Disabled by default
rate_limiter:
max: 100 # requests
expiration: "1m" # per minute
storage: "memory" # or "redis"
```
**Validation Rules**:
- All required fields must be non-empty
- Timeouts must be positive durations
- Pool sizes must be positive integers
- Log filenames must be valid paths
- Rate limiter max must be positive (defaults to 100)
---
## 2. Authentication Model
### AuthToken Entity
**Storage**: Redis key-value pair
**Key Format**: `auth:token:{token_string}` (generated via `constants.RedisAuthTokenKey()`)
**Value Format**: Plain string containing user ID
**TTL**: Managed by Redis (set when token is created)
```go
// Token validation doesn't use a struct - just Redis key-value
// Key: "auth:token:abc123def456"
// Value: "user-789"
// TTL: 3600 seconds (1 hour)
```
**Redis Operations**:
```go
// Store token (example - not part of this feature)
rdb.Set(ctx, constants.RedisAuthTokenKey(token), userID, 1*time.Hour)
// Validate token (this feature)
userID, err := rdb.Get(ctx, constants.RedisAuthTokenKey(token)).Result()
if err == redis.Nil {
// Token not found or expired
}
// Delete token (example - logout feature)
rdb.Del(ctx, constants.RedisAuthTokenKey(token))
```
**Key Generation Function** (`pkg/constants/redis.go`):
```go
// RedisAuthTokenKey generates Redis key for authentication tokens
func RedisAuthTokenKey(token string) string {
return fmt.Sprintf("auth:token:%s", token)
}
```
**Validation Rules**:
- Token must exist as Redis key
- Redis must be available (fail closed if not)
- Token value must be non-empty user ID
- TTL is checked automatically by Redis (expired keys return `redis.Nil`)
---
## 3. Request Context Model
### RequestContext Structure
**File**: `pkg/middleware/context.go` (or stored in Fiber's `c.Locals()`)
```go
// Request context is stored in Fiber's Locals, not a struct
// Access via: c.Locals("key")
// Request ID (set by requestid middleware)
requestID := c.Locals(constants.ContextKeyRequestID).(string) // UUID v4 string
// User ID (set by keyauth middleware after validation)
userID, ok := c.Locals(constants.ContextKeyUserID).(string)
if !ok {
// Not authenticated
}
// Start time (for duration calculation)
startTime := c.Locals(constants.ContextKeyStartTime).(time.Time)
```
**Context Keys** (constants in `pkg/constants/constants.go`):
```go
const (
// Context keys for Fiber Locals
ContextKeyRequestID = "requestid"
ContextKeyUserID = "user_id"
ContextKeyStartTime = "start_time"
)
```
**Lifecycle**:
1. **requestid middleware**: Sets `requestid` in Locals (UUID v4)
2. **logger middleware**: Sets `start_time` in Locals
3. **keyauth middleware**: Sets `user_id` in Locals (after validation)
4. **handler**: Accesses context values from Locals
5. **logger middleware** (after handler): Calculates duration and logs
---
## 4. Log Entry Models
### Application Log Entry
**Format**: JSON
**Output**: `logs/app.log`
**Logger**: Zap (appLogger instance)
```json
{
"timestamp": "2025-11-10T15:30:45.123Z",
"level": "info",
"logger": "service.user",
"caller": "user/service.go:42",
"message": "User created successfully",
"request_id": "550e8400-e29b-41d4-a716-446655440000",
"user_id": "user-789",
"username": "john_doe",
"ip": "192.168.1.100"
}
```
**Fields**:
- `timestamp`: ISO 8601 format (RFC3339)
- `level`: debug, info, warn, error
- `logger`: Logger name (optional, for structured logging)
- `caller`: Source file and line number
- `message`: Log message
- `request_id`: Request correlation ID (if available)
- `user_id`: Authenticated user ID (if available)
- Custom fields: Any additional context-specific fields
**Zap Usage**:
```go
appLogger.Info("User created successfully",
zap.String("request_id", requestID),
zap.String(constants.ContextKeyUserID, userID),
zap.String("username", username),
zap.String("ip", ip),
)
```
### Access Log Entry Format
**Purpose**: Records all HTTP requests for audit trail, performance monitoring, and troubleshooting
**Format**: JSON (one entry per line)
**Output**: `logs/access.log`
**Logger**: Zap (accessLogger instance)
**Requirement**: Implements spec.md FR-011
**Complete JSON Schema**:
```json
{
"timestamp": "2025-11-10T15:30:45.123Z",
"level": "info",
"method": "POST",
"path": "/api/v1/users",
"status": 200,
"duration_ms": 45.234,
"request_id": "550e8400-e29b-41d4-a716-446655440000",
"ip": "192.168.1.100",
"user_agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)...",
"user_id": "user-789"
}
```
**Field Definitions**:
| Field | Type | Required | Description | Example |
|-------|------|----------|-------------|---------|
| `timestamp` | string | Yes | ISO 8601 timestamp (RFC3339 with milliseconds) | `2025-11-10T15:30:45.123Z` |
| `level` | string | Yes | Log level (always "info" for access logs) | `info` |
| `method` | string | Yes | HTTP method | `GET`, `POST`, `PUT`, `DELETE`, `PATCH` |
| `path` | string | Yes | Request path (including query params) | `/api/v1/users?page=1` |
| `status` | int | Yes | HTTP status code | `200`, `401`, `500` |
| `duration_ms` | float64 | Yes | Request processing duration in milliseconds | `45.234` |
| `request_id` | string | Yes | UUID v4 request identifier | `550e8400-e29b-41d4-a716-446655440000` |
| `ip` | string | Yes | Client IP address | `192.168.1.100` |
| `user_agent` | string | Yes | User-Agent header value | `Mozilla/5.0...` |
| `user_id` | string | No | Authenticated user ID (empty string if not authenticated) | `user-789` or `""` |
**Notes**:
- All access logs are written at "info" level
- `user_id` field is empty string (`""`) for unauthenticated requests
- `duration_ms` includes full middleware chain execution time
- `path` includes query parameters for complete request tracking
- Logged after response is sent (includes actual status code)
**Zap Usage**:
```go
accessLogger.Info("",
zap.String("method", c.Method()),
zap.String("path", c.Path()),
zap.Int("status", c.Response().StatusCode()),
zap.Float64("duration_ms", duration.Seconds()*1000),
zap.String("request_id", requestID),
zap.String("ip", c.IP()),
zap.String("user_agent", c.Get("User-Agent")),
zap.String(constants.ContextKeyUserID, userID),
)
```
---
## 5. API Response Model
### Unified Response Structure
**File**: `pkg/response/response.go`
```go
// Response is the unified API response structure
type Response struct {
Code int `json:"code"` // Application error code (0 = success)
Data interface{} `json:"data"` // Response data (object, array, or null)
Message string `json:"msg"` // Human-readable message
Timestamp string `json:"timestamp"` // ISO 8601 timestamp (optional, can be added)
}
// Success returns a successful response
func Success(c *fiber.Ctx, data interface{}) error {
return c.JSON(Response{
Code: 0,
Data: data,
Message: "success",
Timestamp: time.Now().Format(time.RFC3339),
})
}
// Error returns an error response
func Error(c *fiber.Ctx, httpStatus int, code int, message string) error {
return c.Status(httpStatus).JSON(Response{
Code: code,
Data: nil,
Message: message,
Timestamp: time.Now().Format(time.RFC3339),
})
}
// SuccessWithMessage returns a successful response with custom message
func SuccessWithMessage(c *fiber.Ctx, data interface{}, message string) error {
return c.JSON(Response{
Code: 0,
Data: data,
Message: message,
Timestamp: time.Now().Format(time.RFC3339),
})
}
```
**Success Response Example**:
```json
{
"code": 0,
"data": {
"id": "user-123",
"name": "John Doe",
"email": "john@example.com"
},
"msg": "success",
"timestamp": "2025-11-10T15:30:45Z"
}
```
**Error Response Example**:
```json
{
"code": 1002,
"data": null,
"msg": "Invalid or expired token",
"timestamp": "2025-11-10T15:30:45Z"
}
```
**List Response Example**:
```json
{
"code": 0,
"data": [
{"id": "1", "name": "Item 1"},
{"id": "2", "name": "Item 2"}
],
"msg": "success",
"timestamp": "2025-11-10T15:30:45Z"
}
```

## 6. Error Model
### Error Code Constants
**File**: `pkg/errors/codes.go`
```go
// Application error codes
const (
CodeSuccess = 0 // Success
CodeInternalError = 1000 // Internal server error
CodeMissingToken = 1001 // Missing authentication token
CodeInvalidToken = 1002 // Invalid or expired token
CodeTooManyRequests = 1003 // Too many requests (rate limited)
CodeAuthServiceUnavailable = 1004 // Authentication service unavailable (Redis down)
)
// Error messages (bilingual)
var errorMessages = map[int]struct {
EN string
ZH string
}{
CodeSuccess: {"Success", "成功"},
CodeInternalError: {"Internal server error", "内部服务器错误"},
CodeMissingToken: {"Missing authentication token", "缺失认证令牌"},
CodeInvalidToken: {"Invalid or expired token", "令牌无效或已过期"},
CodeTooManyRequests: {"Too many requests", "请求过于频繁"},
CodeAuthServiceUnavailable: {"Authentication service unavailable", "认证服务不可用"},
}
// GetMessage returns error message for given code and language
func GetMessage(code int, lang string) string {
msg, ok := errorMessages[code]
if !ok {
return "Unknown error"
}
if lang == "zh" {
return msg.ZH
}
return msg.EN
}
```
### Custom Error Types
**File**: `pkg/errors/errors.go`
```go
import "errors"
// Standard error types for middleware
var (
ErrMissingToken = errors.New("missing authentication token")
ErrInvalidToken = errors.New("invalid or expired token")
ErrRedisUnavailable = errors.New("redis unavailable")
ErrTooManyRequests = errors.New("too many requests")
)
// AppError represents an application error with code
type AppError struct {
Code int // Application error code
Message string // Error message
Err error // Underlying error (optional)
}
func (e *AppError) Error() string {
if e.Err != nil {
return fmt.Sprintf("%s: %v", e.Message, e.Err)
}
return e.Message
}
func (e *AppError) Unwrap() error {
return e.Err
}
// New creates a new AppError
func New(code int, message string) *AppError {
return &AppError{
Code: code,
Message: message,
}
}
// Wrap wraps an existing error with code and message
func Wrap(code int, message string, err error) *AppError {
return &AppError{
Code: code,
Message: message,
Err: err,
}
}
```

## 7. Rate Limit State Model
### Rate Limit Tracking
**Storage**: In-memory (default) or Redis (for distributed)
**Managed by**: Fiber limiter middleware (internal storage)
```go
// Rate limit state is managed internally by Fiber limiter
// For memory storage: map[string]*limiterEntry
// For Redis storage: Redis keys with TTL
// Memory storage structure (internal to Fiber)
type limiterEntry struct {
count int // Current request count
expiration time.Time // Window expiration time
}
// Redis storage structure (if using Redis storage)
// Key: "ratelimit:{ip_address}"
// Value: JSON {"count": 5, "expiration": "2025-11-10T15:31:00Z"}
// TTL: Same as expiration window
```
**Key Generation** (for custom Redis storage):
```go
// pkg/constants/redis.go
func RedisRateLimitKey(ip string) string {
return fmt.Sprintf("ratelimit:%s", ip)
}
```
**Access Pattern**:
- Middleware checks rate limit state before handler
- Increment counter on each request
- Reset counter when window expires
- Return 429 when limit exceeded

## Data Flow Diagram
### Request Processing Flow
```
1. HTTP Request arrives
↓
2. Recover Middleware (catch panics)
↓
3. RequestID Middleware (generate UUID v4)
→ Store in c.Locals(constants.ContextKeyRequestID)
↓
4. Logger Middleware (start)
→ Store start_time in c.Locals(constants.ContextKeyStartTime)
↓
5. KeyAuth Middleware
→ Extract token from header
→ Call TokenValidator.Validate(token)
→ Validate with Redis: GET auth:token:{token}
→ If valid: Store user_id in c.Locals(constants.ContextKeyUserID)
→ If invalid: Return 401 with error code
→ If Redis down: Return 503 with error code
↓
6. [RateLimiter Middleware] (if enabled)
→ Check rate limit for c.IP()
→ If exceeded: Return 429 with error code
↓
7. Handler (business logic)
→ Access c.Locals(constants.ContextKeyRequestID), c.Locals(constants.ContextKeyUserID)
→ Process request
→ Return response via response.Success() or response.Error()
↓
8. Logger Middleware (end)
→ Calculate duration
→ Log to access.log with all context
↓
9. HTTP Response sent
```

## Summary
**Key Entities**:
1. **Config**: Application configuration (YAML → struct)
2. **AuthToken**: Redis key-value (token → user ID)
3. **RequestContext**: Fiber Locals (requestid, user_id, start_time)
4. **LogEntry**: JSON logs (app.log, access.log)
5. **Response**: Unified API response ({code, data, msg})
6. **Error**: Error codes and custom types
7. **RateLimitState**: Managed by Fiber limiter (memory or Redis)
**Design Principles**:
- ✅ Simple, flat structures (no deep nesting)
- ✅ Direct field access (no getters/setters)
- ✅ Composition over inheritance
- ✅ Explicit error handling
- ✅ Go naming conventions (URL, ID, HTTP)
- ✅ No Java-style patterns (no I-prefix, no Impl-suffix)
**Next**: Generate API contracts (OpenAPI specification)

## 8. Configuration Validation Rules
This section defines comprehensive validation constraints for all configuration fields, implementing the requirements in spec.md FR-003.
### Validation Error Format
All validation errors MUST follow this format:
```

---
### Validation Implementation Guidelines
**Location**: `pkg/config/loader.go` - `Validate()` function
**Validation Order**:
1. **Required fields check** - Fail fast if critical fields missing
2. **Type validation** - Viper handles basic type conversion
3. **Range validation** - Check numeric bounds
4. **Format validation** - Validate string formats (HOST:PORT, file paths)
5. **Cross-field validation** - Check dependencies (e.g., min_idle_conns <= pool_size)
**Example Implementation Pattern**:
```go
func (c *Config) Validate() error {
// Required fields
if c.Server.Address == "" {
return fmt.Errorf("Invalid configuration: server.address: must be non-empty (current value: empty)")
}
// Range validation
if c.Server.ReadTimeout < 5*time.Second || c.Server.ReadTimeout > 300*time.Second {
return fmt.Errorf("Invalid configuration: server.read_timeout: duration out of range (current value: %s, expected: 5s-300s)", c.Server.ReadTimeout)
}
// Format validation
if !strings.Contains(c.Redis.Address, ":") {
return fmt.Errorf("Invalid configuration: redis.address: invalid format (current value: %s, expected: HOST:PORT)", c.Redis.Address)
}
// Cross-field validation
if c.Redis.MinIdleConns > c.Redis.PoolSize {
return fmt.Errorf("Invalid configuration: redis.min_idle_conns: must not exceed pool_size (current value: %d, pool_size: %d)", c.Redis.MinIdleConns, c.Redis.PoolSize)
}
return nil
}
```
**Testing Requirements**:
- Unit tests MUST cover all validation rules (T020 in tasks.md)
- Test valid configurations (should pass)
- Test each constraint violation (should fail with correct error message)
- Test edge cases (min/max boundaries)
- Test malformed YAML (should be caught by Viper)

# Optional Improvements for 001-fiber-middleware-integration
**Created**: 2025-11-11
**Status**: Deferred - Address after core implementation
**Source**: `/speckit.analyze` findings (Medium/Low priority)
---
## Medium Priority Improvements
### A2: Log Retention Policy Clarity
- **Issue**: FR-006 mentions "configured retention policy" but doesn't specify units/format
- **Current Impact**: Implementation will need to infer format
- **Recommendation**: Add to spec.md FR-006:
```
Retention policy specified in days (integer), e.g., 30 for app logs, 90 for access logs.
Implemented via Lumberjack MaxAge parameter.
```
- **Effort**: 10 minutes (documentation only)
---
### A3: Rate Limiting Default Values
- **Issue**: FR-018a says "configurable requests per time window" but no default values
- **Current Impact**: Developers must guess initial values
- **Recommendation**: Add to spec.md FR-018a:
```
Default: 100 requests per minute per IP
Supported time units: second (s), minute (m), hour (h)
Example config: max=100, window=1m
```
- **Effort**: 15 minutes (spec update + config.yaml example)
---
### A5: Phase 0 Research Status
- **Issue**: plan.md Phase 0 lists "Best Redis client" as unknown but Technical Context already decided
- **Current Impact**: Confusion about whether research is needed
- **Recommendation**: Update plan.md Phase 0:
- Remove "Best Redis client" from unknowns (already decided: go-redis/redis/v8)
- Or clarify: "Validate go-redis/redis/v8 choice (performance benchmarks, connection pool tuning)"
- **Effort**: 5 minutes (documentation clarity)
---
### A6: Config Validation Rules Location
- **Issue**: T009 says "config loading with validation" but validation rules not documented
- **Current Impact**: Developer must design validation rules during implementation
- **Recommendation**: Create section in data-model.md or spec.md:
```markdown
## Configuration Validation Rules
- server.port: 1024-65535 (int)
- server.host: non-empty string
- redis.addr: host:port format
- logging.max_size: 1-1000 (MB)
- logging.max_age: 1-365 (days)
```
- **Effort**: 30 minutes (requires design decisions)
---
### U2: Access Log Format Specification
- **Issue**: FR-011 mentions logging HTTP requests but doesn't specify JSON schema for access.log
- **Current Impact**: Access log structure determined during implementation
- **Recommendation**: Add to spec.md or data-model.md:
```json
{
"timestamp": "2025-11-10T15:30:45Z",
"level": "info",
"request_id": "550e8400-e29b-...",
"method": "GET",
"path": "/api/v1/users",
"status": 200,
"duration_ms": 45,
"ip": "192.168.1.100",
"user_agent": "Mozilla/5.0...",
"user_id": "12345" // if authenticated
}
```
- **Effort**: 20 minutes (design + documentation)
---
### U3: Panic Response Details
- **Issue**: FR-014 says "HTTP 500 with unified error response" but unclear about stack trace handling
- **Current Impact**: Security concern - should stack traces be in production responses?
- **Recommendation**: Clarify in spec.md FR-014:
```
Development/Staging: Include sanitized error message in response.msg, full stack trace in logs only
Production: Generic error message "Internal server error", full details in logs only
Response format: {"code": 1000, "data": null, "msg": "Internal server error"}
```
- **Effort**: 15 minutes (security consideration + spec update)
---
### U4: Rate Limiter Documentation Format
- **Issue**: FR-020 mentions "documentation" but unclear where (quickstart.md? inline comments? separate docs/)
- **Current Impact**: Documentation may be incomplete or scattered
- **Recommendation**: Specify in spec.md FR-020:
```
Documentation location: quickstart.md section "Enabling Rate Limiting"
Must include: Configuration parameters, per-endpoint setup, testing examples
Code example: Uncomment middleware, adjust max/window, test with curl loop
```
- **Effort**: 10 minutes (clarify requirements)
---
### U5: Non-Writable Log Directory Behavior
- **Issue**: Edge case says "fail to start with clear error" but no HTTP status code if started
- **Current Impact**: Unclear behavior if directory becomes non-writable at runtime
- **Recommendation**: Clarify in spec.md Edge Cases:
```
Startup: Fail immediately with exit code 1 and error message before listening on port
Runtime: If directory becomes non-writable, log error to stderr and return 503 on health check
```
- **Effort**: 15 minutes (design decision + spec update)
---
### U6: Performance Test Task Missing
- **Issue**: plan.md mentions "1000+ req/s capacity" but no performance test task in tasks.md
- **Current Impact**: Performance goal not validated
- **Recommendation**: Add task to tasks.md Phase 10:
```
- [ ] T117a [P] Load test with 1000 req/s for 60s, verify P95 < 200ms (use hey or wrk)
```
- **Effort**: 1 hour (implementation + infrastructure setup)
---
### I1: Logger Instances Documentation
- **Issue**: spec.md mentions Zap but tasks reference appLogger/accessLogger instances
- **Current Impact**: Spec doesn't explicitly require two logger instances
- **Recommendation**: Add to spec.md FR-004 or Key Entities:
```
System maintains two independent Zap logger instances:
- appLogger: For application-level logs (business logic, errors, debug)
- accessLogger: For HTTP access logs (request/response details)
Each instance has separate Lumberjack rotation configuration.
```
- **Effort**: 10 minutes (documentation clarity)
---
### I3: Fail-Closed Timing Validation
- **Issue**: spec.md FR-016b says "immediately" but T063 doesn't validate timing (< 100ms)
- **Current Impact**: "Immediate" is subjective, no performance assertion
- **Recommendation**: Update tasks.md T063:
```
- [ ] T063 [P] [US6] Unit test for Redis unavailable (fail closed with < 100ms response time)
```
Or clarify spec.md: "immediately = same request cycle, no retry delays"
- **Effort**: 5 minutes (clarify requirements OR 30 minutes add timing assertion)
---
## Low Priority Improvements
### D1: Response Format Duplication
- **Issue**: FR-007 and US3 both define unified response format
- **Current Impact**: Redundancy, potential inconsistency if one updated
- **Recommendation**: Keep FR-007 as normative, update US3 acceptance criteria:
```
Change: "the response contains `{...}`"
To: "the response follows unified format defined in FR-007"
```
- **Effort**: 5 minutes (reduce duplication)
---
### D2: Code Quality Task Consolidation
- **Issue**: T096-T099 are four separate tasks that could run in one script
- **Current Impact**: Overhead running tasks sequentially
- **Recommendation**: Consider combining to T096-combined:
```
- [ ] T096 [P] Run code quality checks: gofmt -l ., go vet ./..., golangci-lint run, check doc comments
```
Or keep separate for granular progress tracking (current approach is also valid)
- **Effort**: 15 minutes (script creation) OR keep as-is (no change needed)
---
### I4: Task Count Verification
- **Issue**: plan.md says 126 tasks, tasks.md has T001-T126 (now T127 with T012a)
- **Current Impact**: None - counts match after update
- **Recommendation**: No action needed, already addressed in C1 fix
- **Effort**: 0 minutes (already resolved)
---
## Priority Recommendation
**Before Implementation**:
- None (all HIGH priority issues already fixed)
**During Implementation** (if time permits):
- A6: Config validation rules (needed for T009 implementation)
- U2: Access log format (needed for T050 implementation)
- U3: Panic response details (security consideration)
**After Implementation** (polish phase):
- A2, A3: Add default values to config.yaml and documentation
- U4, U5, I1: Documentation improvements
- U6: Performance testing (if infrastructure available)
- D1, D2, I3: Nice-to-have optimizations
---
## Summary
- **Total Optional Improvements**: 14 items
- **Medium Priority**: 9 items (mostly documentation/specification clarity)
- **Low Priority**: 5 items (minor optimizations, already acceptable as-is)
- **Estimated Total Effort**: ~4 hours for all medium priority items
- **Recommended Approach**: Address medium priority items during implementation when context is fresh

# Implementation Plan: Fiber Middleware Integration with Configuration Management
**Branch**: `001-fiber-middleware-integration` | **Date**: 2025-11-10 | **Spec**: [spec.md](./spec.md)
**Input**: Feature specification from `/specs/001-fiber-middleware-integration/spec.md`
**Note**: This template is filled in by the `/speckit.plan` command. See `.specify/templates/commands/plan.md` for the execution workflow.
## Summary
Integrate essential Fiber middleware (logger, recover, requestid, keyauth, limiter) with unified response structure, Viper configuration hot reload, and Zap+Lumberjack logging. This establishes the foundational middleware layer for the 君鸿卡管系统, ensuring proper authentication, logging, error recovery, and request tracing capabilities following Go idiomatic patterns.
## Technical Context
**Language/Version**: Go 1.25.1
**Primary Dependencies**:
- Fiber v2.52.9 (HTTP framework)
- Sonic v1.14.2 (JSON encoding/decoding - already integrated)
- Viper (configuration with hot reload)
- Zap (structured logging)
- Lumberjack.v2 (log rotation)
- Redis client (for keyauth token validation)
**Storage**:
- Redis (for authentication token validation - token as key, user ID as value with TTL)
- Log files (app.log for application logs, access.log for HTTP access logs)
**Testing**:
- Go standard testing framework (`testing` package)
- Table-driven tests for middleware logic
- Integration tests for API endpoints with middleware
- Mock Redis for keyauth testing
**Target Platform**: Linux server (production), macOS (development)
**Project Type**: Single backend web service (Go web application)
**Performance Goals**:
- API response time P95 < 200ms, P99 < 500ms
- Middleware overhead < 5ms per request
- Configuration hot reload detection within 5 seconds
- Log rotation without blocking requests
**Constraints**:
- No external authentication service (Redis-only token validation)
- Fail-closed authentication (Redis unavailable = HTTP 503)
- Zero downtime for configuration changes (hot reload)
- Separate log files with independent retention policies
**Scale/Scope**:
- Foundation for multi-module card management system
- ~10 initial API endpoints (will grow)
- Expected 1000+ req/s capacity
- 24/7 production availability requirement
## Constitution Check
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
**Tech Stack Adherence**:
- [x] Feature uses Fiber + Viper + Zap + Lumberjack.v2 + sonic JSON + Redis
- [x] No native calls bypass framework (no `net/http` direct use)
- [x] All HTTP operations use Fiber framework
- [x] All async tasks use Asynq (N/A for this feature - no async tasks)
- [x] Uses Go official toolchain: `go fmt`, `go vet`, `golangci-lint`
- [x] Uses Go Modules for dependency management (already initialized)
**Code Quality Standards**:
- [x] Follows Handler → Service → Store → Model architecture (keyauth validation follows this)
- [x] Handler layer only handles HTTP, no business logic
- [x] Service layer contains business logic with cross-module support
- [x] Store layer manages all data access with transaction support
- [x] Uses dependency injection via struct fields (not constructor patterns)
- [x] Unified error codes in `pkg/errors/` (will define auth error codes: 1001-1004)
- [x] Unified API responses via `pkg/response/` (core requirement: {code, data, msg})
- [x] All constants defined in `pkg/constants/` (Redis keys, error messages)
- [x] All Redis keys managed via key generation functions (no hardcoded strings)
- [x] All exported functions/types have Go-style doc comments
- [x] Code formatted with `gofmt`
- [x] Follows Effective Go and Go Code Review Comments
**Go Idiomatic Design**:
- [x] Package structure is flat (max 2-3 levels), organized by feature
- Structure: `pkg/config/`, `pkg/logger/`, `pkg/response/`, `pkg/errors/`, `pkg/constants/`
- Middleware: `internal/middleware/` (flat, no deep nesting)
- [x] Interfaces are small (1-3 methods), defined at use site
- TokenValidator interface (2 methods: ValidateToken, IsAvailable)
- [x] No Java-style patterns: no I-prefix, no Impl-suffix, no getters/setters
- [x] Error handling is explicit (return errors, no panic/recover abuse)
- Recover middleware captures panics only, normal errors use error returns
- [x] Uses composition over inheritance
- [x] Uses goroutines and channels for config hot reload watcher
- [x] Uses `context.Context` for cancellation and timeouts
- [x] Naming follows Go conventions: short receivers, consistent abbreviations (URL, ID, HTTP)
- [x] No Hungarian notation or type prefixes
- [x] Simple constructors (New/NewXxx), no Builder pattern unless necessary
**Testing Standards**:
- [x] Unit tests for all core business logic (token validation, config loading)
- [x] Integration tests for all API endpoints with middleware chain
- [x] Tests use Go standard testing framework
- [x] Test files named `*_test.go` in same directory
- [x] Test functions use `Test` prefix, benchmarks use `Benchmark` prefix
- [x] Table-driven tests for multiple test cases (especially middleware scenarios)
- [x] Test helpers marked with `t.Helper()`
- [x] Tests are independent (mock Redis, no external dependencies)
- [x] Target coverage: 70%+ overall, 90%+ for core business (auth, config)
**User Experience Consistency**:
- [x] All APIs use unified JSON response format: `{code, data, msg}`
- [x] Error responses include clear error codes and bilingual messages
- 1001: Missing authentication token (缺失认证令牌)
- 1002: Invalid or expired token (令牌无效或已过期)
- 1003: Too many requests (请求过于频繁)
- 1004: Authentication service unavailable (认证服务不可用)
- [x] RESTful design principles followed
- [x] Unified pagination parameters (N/A for this feature)
- [x] Time fields use ISO 8601 format (RFC3339) - in log timestamps
- [x] Currency amounts use integers (N/A for this feature)
**Performance Requirements**:
- [x] API response time (P95) < 200ms, (P99) < 500ms
- Middleware overhead budgeted at < 5ms per request
- [x] Batch operations use bulk queries/inserts (N/A for this feature)
- [x] All database queries have appropriate indexes (N/A - Redis only)
- [x] List queries implement pagination (N/A for this feature)
- [x] Non-realtime operations use async tasks (N/A - all operations are realtime)
- [x] Database and Redis connection pools properly configured
- Redis: PoolSize=10, MinIdleConns=5
- [x] Uses goroutines/channels for concurrency (config watcher)
- [x] Uses `context.Context` for timeout control (Redis operations)
- [x] Uses `sync.Pool` for frequently allocated objects (if needed for performance)

```
**Structure Decision**: Single project structure (Option 1) as this is a backend-only Go web service. The project follows Go's standard layout with `cmd/` for entry points, `internal/` for private application code, and `pkg/` for reusable packages. Configuration files are centralized in `configs/` with environment-specific overrides. This structure aligns with Go best practices and the constitution's flat package organization principle.
## Complexity Tracking
> **Fill ONLY if Constitution Check has violations that must be justified**
*No violations detected. All requirements align with constitution principles.*
## Phase 0: Research & Discovery
**Status**: Starting research phase
**Research Tasks**:
1. Viper configuration hot reload best practices and implementation patterns
2. Zap + Lumberjack integration patterns for dual log files (app.log, access.log)
3. Fiber middleware execution order and error handling patterns
4. Fiber keyauth middleware customization for Redis token validation
5. Fiber limiter middleware configuration options and IP extraction
6. Redis connection pool configuration for go-redis/redis/v8 (already decided)
7. UUID v4 generation using github.com/google/uuid (already in go.mod)
8. Graceful shutdown patterns for config watchers and HTTP server
**Unknowns to Resolve**:
- Optimal Viper hot reload implementation (polling vs fsnotify - recommend fsnotify)
- How to properly separate Fiber logger middleware output to access.log
- How to inject custom Zap logger into Fiber recover middleware
- Request ID propagation through Fiber context
- Testing strategies for middleware integration tests
**Output**: `research.md` with decisions and rationale
---
## Phase 1: Design & Contracts
**Prerequisites**: Phase 0 research complete
**Design Artifacts**:
1. **data-model.md**: Entity definitions
- Configuration structure (server, redis, logging, middleware settings)
- AuthToken entity (Redis key-value structure)
- Request Context structure (request ID, user ID, metadata)
- Log Entry structure (JSON fields for app.log and access.log)
- Rate Limit State (IP-based tracking structure)
2. **contracts/api.yaml**: OpenAPI specification
- Unified response format schema
- Error response schemas (1001-1004)
- Common headers (X-Request-ID, token)
- Example endpoints demonstrating middleware integration
3. **quickstart.md**: Developer setup guide
- Environment setup (Go, Redis)
- Configuration file setup (config.yaml)
- Running the server
- Testing middleware (curl examples)
- Enabling/disabling rate limiter
**Output**: data-model.md, contracts/api.yaml, quickstart.md
---
## Phase 2: Task Generation
**Status**: To be completed by `/speckit.tasks` command (NOT part of `/speckit.plan`)
This phase will generate `tasks.md` with implementation steps ordered by dependencies.
---
## Notes & Decisions
### Key Design Decisions (from spec clarifications):
1. **Log Separation**: Application logs (app.log) and HTTP access logs (access.log) in separate files with independent rotation and retention policies
2. **Token Storage**: Simple Redis key-value (token → user ID) with Redis TTL for expiration
3. **Auth Failure Mode**: Fail closed when Redis unavailable (HTTP 503, no fallback)
4. **Rate Limiting**: Per-IP address with configurable requests/time window, disabled by default
5. **Request ID Format**: UUID v4 for distributed tracing compatibility
6. **Config Hot Reload**: 5-second detection window, atomic updates, invalid config = keep previous
### Technical Choices (to be validated in Phase 0):
- Use `github.com/go-redis/redis/v8` for Redis client (widely adopted, good performance)
- Use `github.com/fsnotify/fsnotify` (Viper's native watcher) for hot reload
- Use `github.com/google/uuid` (already in go.mod) for UUID v4 generation
- Separate Zap logger instances for app.log and access.log:
- **appLogger**: Initialized with Lumberjack writer pointing to `app.log` with independent rotation settings (max size, max age, max backups, compression). Used for all application-level logging (business logic, errors, middleware events, debug info).
- **accessLogger**: Initialized with separate Lumberjack writer pointing to `access.log` with independent rotation settings. Used exclusively for HTTP access logs (request method, path, status, duration, request ID, IP, user agent, user ID).
- Both loggers use Zap's structured JSON encoder with consistent field naming.
- Logger instances are global variables (package-level) initialized in `pkg/logger/logger.go` via `InitLoggers()` function called from `main.go` at startup.
- Each logger has its own Lumberjack configuration to enable different retention policies (e.g., 30 days for app.log, 90 days for access.log).
- Middleware order: recover → requestid → logger → keyauth → limiter → handler
### Risk Mitigation:
- **Risk**: Configuration hot reload causes in-flight request issues
- **Mitigation**: Use atomic pointer swap for config updates, don't affect in-flight requests
- **Risk**: Log rotation blocks request processing
- **Mitigation**: Lumberjack handles rotation atomically, Zap is non-blocking
- **Risk**: Redis connection pool exhaustion under load
- **Mitigation**: Proper pool sizing (10 connections), timeout configuration, circuit breaker consideration
- **Risk**: Rate limiter memory leak with many unique IPs
- **Mitigation**: Use Fiber's built-in limiter with storage backend (memory or Redis), TTL cleanup

## Phase 1 Constitution Re-Check
**Status**: ✅ PASSED - All design artifacts comply with constitution
**Verification Results**:
1. **Go Idiomatic Design** ✅
- ✅ Flat package structure: `pkg/config/`, `pkg/logger/`, `pkg/response/`, `pkg/errors/`
- ✅ Small interfaces: TokenValidator (2 methods only)
- ✅ No Java patterns: No IService, no Impl suffix, no getters/setters
- ✅ Simple structs with direct field access (Config, Response, LogEntry)
- ✅ Explicit error handling with custom error types
- ✅ Composition: Config composed of sub-configs, no inheritance
2. **Tech Stack Compliance** ✅
- ✅ Fiber for all HTTP operations (middleware, routing)
- ✅ Viper for configuration with hot reload
- ✅ Zap + Lumberjack for logging
- ✅ go-redis/redis/v8 for Redis client
- ✅ google/uuid for request ID generation
- ✅ No `net/http`, `database/sql`, or `encoding/json` direct usage
3. **Architecture Alignment** ✅
- ✅ Clear separation: Middleware → Handler → Service (TokenValidator) → Store (Redis)
- ✅ Dependency injection via struct fields
- ✅ Unified response format in `pkg/response/`
- ✅ Error codes centralized in `pkg/errors/`
- ✅ Constants and Redis key functions in `pkg/constants/`
4. **Performance Requirements** ✅
- ✅ Middleware overhead budgeted at <5ms per request
- ✅ Redis connection pool configured (10 connections, 5 idle)
- ✅ Goroutines for config watcher (non-blocking)
- ✅ Context timeouts for Redis operations (50ms)
- ✅ Lumberjack non-blocking log rotation
5. **Testing Strategy** ✅
- ✅ Table-driven tests planned (Go idiomatic)
- ✅ Mock Redis for unit tests
- ✅ Integration tests with testcontainers
- ✅ Target coverage defined (70%+ overall, 90%+ core)
**Design Quality Metrics**:
- Zero Java-style anti-patterns detected
- All error handling explicit (no panic/recover abuse)
- Configuration validation implemented
- Graceful shutdown pattern defined
- Security: Fail-closed auth, explicit timeout handling
**Conclusion**: Design is ready for implementation. All artifacts (research.md, data-model.md, contracts/api.yaml, quickstart.md) align with constitution principles. No violations or exceptions required.

# Quick Start Guide: Fiber Middleware Integration
**Feature**: 001-fiber-middleware-integration
**Date**: 2025-11-10
**Phase**: 1 - Design & Contracts
## Overview
This guide helps developers set up and test the Fiber middleware integration locally. It covers environment setup, configuration, running the server, and testing middleware functionality.
---
## Prerequisites
### Required Software
- **Go**: 1.25.1 or higher
- **Redis**: 7.x or higher (for authentication)
- **Git**: For version control
### Check Versions
```bash
go version # Should show go1.25.1 or higher
redis-server --version # Should show Redis 7.x
```
---
## Environment Setup
### 1. Install Redis (if not already installed)
**macOS (Homebrew)**:
```bash
brew install redis
brew services start redis
```
**Linux (Ubuntu/Debian)**:
```bash
sudo apt-get update
sudo apt-get install redis-server
sudo systemctl start redis
sudo systemctl enable redis
```
**Verify Redis is running**:
```bash
redis-cli ping
# Should return: PONG
```
### 2. Clone Repository and Install Dependencies
```bash
cd /Users/break/csxjProject/junhong_cmp_fiber
# Install Go dependencies
go mod tidy
```
### 3. Create Configuration File
Create `configs/config.yaml` with the following content:
```yaml
server:
address: ":3000"
read_timeout: "10s"
write_timeout: "10s"
shutdown_timeout: "30s"
prefork: false
redis:
address: "localhost:6379"
password: ""
db: 0
pool_size: 10
min_idle_conns: 5
dial_timeout: "5s"
read_timeout: "3s"
write_timeout: "3s"
logging:
level: "info"
development: false
app_log:
filename: "logs/app.log"
max_size: 100 # MB
max_backups: 30
max_age: 30 # days
compress: true
access_log:
filename: "logs/access.log"
max_size: 500 # MB
max_backups: 90
max_age: 90 # days
compress: true
middleware:
enable_auth: true
enable_rate_limiter: false # Disabled by default
rate_limiter:
max: 100 # requests
expiration: "1m" # per minute
storage: "memory" # or "redis"
```
### 4. Create Logs Directory
```bash
mkdir -p logs
```
---
## Running the Server
### Development Mode
```bash
# Run API server
go run cmd/api/main.go
```
**Expected output**:
```
2025-11-10T15:30:00Z INFO Server starting {"address": ":3000"}
2025-11-10T15:30:00Z INFO Redis connected {"address": "localhost:6379"}
2025-11-10T15:30:00Z INFO Config watcher started
```
### Production Mode
```bash
# Build binary
go build -o bin/api cmd/api/main.go
# Run binary
./bin/api
```
---
## Testing Middleware
### 1. Health Check (No Authentication)
```bash
curl -i http://localhost:3000/health
```
**Expected response**:
```
HTTP/1.1 200 OK
X-Request-ID: 550e8400-e29b-41d4-a716-446655440000
Content-Type: application/json
{
"code": 0,
"data": {
"status": "healthy",
"timestamp": "2025-11-10T15:30:45Z"
},
"msg": "success",
"timestamp": "2025-11-10T15:30:45Z"
}
```
**Note**: Check the `X-Request-ID` header - this is a UUID v4 generated by the requestid middleware.
### 2. Missing Token (401 Error)
```bash
curl -i http://localhost:3000/api/v1/users
```
**Expected response**:
```
HTTP/1.1 401 Unauthorized
X-Request-ID: 550e8400-e29b-41d4-a716-446655440001
Content-Type: application/json
{
"code": 1001,
"data": null,
"msg": "Missing authentication token",
"timestamp": "2025-11-10T15:30:46Z"
}
```
### 3. Invalid Token (401 Error)
```bash
curl -i -H "token: invalid-token-123" http://localhost:3000/api/v1/users
```
**Expected response**:
```
HTTP/1.1 401 Unauthorized
X-Request-ID: 550e8400-e29b-41d4-a716-446655440002
Content-Type: application/json
{
"code": 1002,
"data": null,
"msg": "Invalid or expired token",
"timestamp": "2025-11-10T15:30:47Z"
}
```
### 4. Create Test Token in Redis
```bash
# Add a test token to Redis (expires in 1 hour)
redis-cli SETEX "auth:token:test-token-abc123" 3600 "user-789"
```
**Verify token**:
```bash
redis-cli GET "auth:token:test-token-abc123"
# Should return: "user-789"
```
### 5. Valid Token (200 Success)
```bash
curl -i -H "token: test-token-abc123" http://localhost:3000/api/v1/users
```
**Expected response**:
```
HTTP/1.1 200 OK
X-Request-ID: 550e8400-e29b-41d4-a716-446655440003
Content-Type: application/json
{
"code": 0,
"data": [
{
"id": "user-123",
"name": "John Doe",
"email": "john@example.com"
}
],
"msg": "success",
"timestamp": "2025-11-10T15:30:48Z"
}
```
### 6. Test Panic Recovery
Create a test endpoint that panics (for testing recover middleware):
```bash
curl -i -H "token: test-token-abc123" http://localhost:3000/api/v1/test-panic
```
**Expected behavior**:
- Server does NOT crash
- Returns HTTP 500 with error response
- Panic is logged to `logs/app.log` with stack trace
- Subsequent requests continue to work normally
### 7. Verify Logging
**Application logs** (`logs/app.log`):
```bash
tail -f logs/app.log
```
**Expected log entries** (JSON format):
```json
{"timestamp":"2025-11-10T15:30:45Z","level":"info","message":"Server starting","address":":3000"}
{"timestamp":"2025-11-10T15:30:46Z","level":"warn","message":"Token validation failed","request_id":"550e8400-e29b-41d4-a716-446655440001","error":"missing token"}
```
**Access logs** (`logs/access.log`):
```bash
tail -f logs/access.log
```
**Expected log entries** (JSON format):
```json
{"timestamp":"2025-11-10T15:30:46Z","level":"info","method":"GET","path":"/api/v1/users","status":401,"duration_ms":12.345,"request_id":"550e8400-e29b-41d4-a716-446655440001","ip":"127.0.0.1","user_agent":"curl/7.88.1","user_id":""}
{"timestamp":"2025-11-10T15:30:48Z","level":"info","method":"GET","path":"/api/v1/users","status":200,"duration_ms":23.456,"request_id":"550e8400-e29b-41d4-a716-446655440003","ip":"127.0.0.1","user_agent":"curl/7.88.1","user_id":"user-789"}
```
---
## Testing Configuration Hot Reload
### 1. Modify Configuration While Server is Running
Edit `configs/config.yaml` and change the log level:
```yaml
logging:
level: "debug" # Changed from "info"
# ... rest unchanged
```
### 2. Verify Configuration Reloaded
**Check application logs**:
```bash
tail -f logs/app.log
```
**Expected log entry** (within 5 seconds):
```json
{"timestamp":"2025-11-10T15:31:00Z","level":"info","message":"Config file changed","file":"configs/config.yaml"}
{"timestamp":"2025-11-10T15:31:00Z","level":"info","message":"Configuration reloaded successfully"}
```
### 3. Test Invalid Configuration
Edit `configs/config.yaml` with invalid YAML:
```yaml
server:
address: ":3000"
invalid syntax here!!!
```
**Expected behavior**:
- Server continues running with previous valid configuration
- Error logged to `logs/app.log`:
```json
{"timestamp":"2025-11-10T15:32:00Z","level":"error","message":"Failed to reload config","error":"yaml: unmarshal error"}
```
### 4. Fix Configuration
Restore valid configuration:
```yaml
server:
address: ":3000"
read_timeout: "10s"
# ... rest of valid config
```
**Expected**: Configuration reloads successfully (logged within 5 seconds).
---
## Testing Rate Limiter (Optional)
Rate limiting is **disabled by default**. To enable and test:
### 1. Enable Rate Limiter in Configuration
Edit `configs/config.yaml`:
```yaml
middleware:
enable_auth: true
enable_rate_limiter: true # 设置为 true 启用限流
rate_limiter:
max: 5 # 每个窗口最大请求数（测试用低值）
expiration: "1m" # 时间窗口：1分钟
storage: "memory" # 存储方式：memory（内存）或 redis（分布式）
```
**Rate Limiter Configuration Options**:
- **`enable_rate_limiter`**: Set to `true` to enable rate limiting (default: `false`)
- **`max`**: Maximum number of requests allowed per time window
- Development: `1000` requests/minute (relaxed for testing)
- Production: `100` requests/minute (stricter limits)
- Testing: `5` requests/minute (for easy testing)
- **`expiration`**: Time window for rate limiting
- Supported formats: `"30s"` (30 seconds), `"1m"` (1 minute), `"5m"` (5 minutes), `"1h"` (1 hour)
- Recommended: `"1m"` for most APIs
- **`storage`**: Storage backend for rate limit counters
- `"memory"`: In-memory storage (single-server deployments)
- Pros: Fast, no external dependencies
- Cons: Limits not shared across server instances, reset on server restart
- `"redis"`: Redis-based storage (multi-server deployments)
- Pros: Distributed rate limiting, persistent across restarts
- Cons: Requires Redis connection, slightly higher latency
**Choosing Storage Backend**:
- Use `"memory"` for:
- Single-server deployments
- Development/testing environments
- When rate limit precision is not critical
- Use `"redis"` for:
- Multi-server/load-balanced deployments
- When you need consistent limits across all servers
- Production environments with high availability requirements
### 2. Restart Server (or wait for hot reload)
```bash
# Option 1: Restart server
# Ctrl+C to stop
go run cmd/api/main.go
# Option 2: Wait 5 seconds for automatic config reload
# (if server is already running)
```
### 3. Test Rate Limiting
Make multiple requests rapidly:
```bash
# Run 10 requests in quick succession
for i in {1..10}; do
curl -w "\nRequest $i: %{http_code}\n" \
-H "token: test-token-abc123" \
http://localhost:3000/api/v1/users
sleep 0.1
done
```
**Expected output**:
```
Request 1: 200
Request 2: 200
Request 3: 200
Request 4: 200
Request 5: 200
Request 6: 429 # Rate limit exceeded (请求过于频繁)
Request 7: 429
Request 8: 429
Request 9: 429
Request 10: 429
```
**Rate limit response** (429 Too Many Requests):
```json
{
"code": 1003,
"data": null,
"msg": "请求过于频繁",
"timestamp": "2025-11-10T15:35:00Z"
}
```
### 4. Test Per-IP Rate Limiting
Rate limiting is applied **per client IP address**. Different IPs have separate rate limits:
```bash
# Simulate requests from different IPs (requires testing infrastructure)
curl -H "X-Forwarded-For: 192.168.1.1" \
-H "token: test-token-abc123" \
http://localhost:3000/api/v1/users
# Returns 200 (separate limit from your local IP)
```
### 5. Wait for Window to Reset
Wait for the time window to expire, then try again:
```bash
# Wait for window expiration (1 minute in this example)
sleep 60
# Try again - limit should be reset
curl -H "token: test-token-abc123" http://localhost:3000/api/v1/users
# Should return 200 again
```
### 6. Test Redis-Based Rate Limiting (Distributed)
For distributed rate limiting across multiple servers:
**Edit `configs/config.yaml`**:
```yaml
middleware:
enable_rate_limiter: true
rate_limiter:
max: 100
expiration: "1m"
storage: "redis" # Changed to redis
```
**Check Redis for rate limit keys**:
```bash
# List rate limit keys in Redis
redis-cli KEYS "rate_limit:*"
# Example output:
# 1) "rate_limit:127.0.0.1"
# 2) "rate_limit:192.168.1.1"
# Check remaining count for an IP
redis-cli GET "rate_limit:127.0.0.1"
# Returns: "5" (requests made in current window)
# Check TTL (time until reset)
redis-cli TTL "rate_limit:127.0.0.1"
# Returns: "45" (45 seconds until window resets)
```
### 7. Disable Rate Limiter
Edit `configs/config.yaml`:
```yaml
middleware:
enable_rate_limiter: false # 设置为 false 禁用限流
```
Server will reload config automatically within 5 seconds (no restart needed).
### 8. Rate Limiter Behavior Summary
| Scenario | Behavior |
|----------|----------|
| Rate limiter disabled | All requests pass through (no rate limiting) |
| Under limit | Request processed normally (200) |
| Limit exceeded | Request rejected with 429 status code |
| Window expires | Counter resets, requests allowed again |
| Different IPs | Each IP has independent rate limit counter |
| Memory storage + restart | All counters reset on server restart |
| Redis storage + restart | Counters persist across server restarts |
| Redis unavailable | Rate limiting continues with in-memory fallback |
### 9. Recommended Rate Limit Values
**API Type** | **max** | **expiration** | **storage**
-------------|---------|----------------|------------
Public API (strict) | 60 | "1m" | redis
Public API (relaxed) | 1000 | "1m" | redis
Internal API | 5000 | "1m" | memory
Admin API | 10000 | "1m" | memory
Development/Testing | 1000 | "1m" | memory
### 10. Monitoring Rate Limiting
**Check access logs** for rate limit events:
```bash
# Filter 429 responses (rate limited)
grep '"status":429' logs/access.log | jq .
# Example output:
{
"timestamp": "2025-11-10T15:35:00Z",
"level": "info",
"method": "GET",
"path": "/api/v1/users",
"status": 429,
"duration_ms": 0.123,
"request_id": "550e8400-e29b-41d4-a716-446655440006",
"ip": "127.0.0.1",
"user_agent": "curl/7.88.1",
"user_id": "user-789"
}
```
**Count rate-limited requests**:
```bash
# Count 429 responses in last hour
grep '"status":429' logs/access.log | grep "$(date -u +%Y-%m-%dT%H)" | wc -l
```
---
## Testing Redis Failure (Fail-Closed Behavior)
### 1. Stop Redis
```bash
# macOS
brew services stop redis
# Linux
sudo systemctl stop redis
```
### 2. Test Authentication
```bash
curl -i -H "token: test-token-abc123" http://localhost:3000/api/v1/users
```
**Expected response** (503 Service Unavailable):
```
HTTP/1.1 503 Service Unavailable
X-Request-ID: 550e8400-e29b-41d4-a716-446655440010
Content-Type: application/json
{
"code": 1004,
"data": null,
"msg": "Authentication service unavailable",
"timestamp": "2025-11-10T15:40:00Z"
}
```
**Check application logs**:
```json
{"timestamp":"2025-11-10T15:40:00Z","level":"error","message":"Redis unavailable","request_id":"550e8400-e29b-41d4-a716-446655440010","error":"dial tcp [::1]:6379: connect: connection refused"}
```
### 3. Restart Redis
```bash
# macOS
brew services start redis
# Linux
sudo systemctl start redis
```
### 4. Verify Recovery
```bash
curl -i -H "token: test-token-abc123" http://localhost:3000/api/v1/users
# Should return 200 again
```
---
## Request ID Tracing
Every request has a unique UUID v4 identifier that appears in:
1. **Response header**: `X-Request-ID`
2. **Access logs**: `request_id` field
3. **Application logs**: `request_id` field (when included)
### Example Request ID Flow
**Request**:
```bash
curl -i -H "token: test-token-abc123" http://localhost:3000/api/v1/users
```
**Response header**:
```
X-Request-ID: 550e8400-e29b-41d4-a716-446655440020
```
**Access log** (`logs/access.log`):
```json
{"timestamp":"2025-11-10T15:45:00Z","level":"info","method":"GET","path":"/api/v1/users","status":200,"duration_ms":15.234,"request_id":"550e8400-e29b-41d4-a716-446655440020","ip":"127.0.0.1","user_agent":"curl/7.88.1","user_id":"user-789"}
```
**Application log** (`logs/app.log`) - if handler logs something:
```json
{"timestamp":"2025-11-10T15:45:00Z","level":"info","message":"Fetching users","request_id":"550e8400-e29b-41d4-a716-446655440020","user_id":"user-789"}
```
### Search Logs by Request ID
```bash
# Search access logs
grep "550e8400-e29b-41d4-a716-446655440020" logs/access.log
# Search application logs
grep "550e8400-e29b-41d4-a716-446655440020" logs/app.log
```
---
## Log Rotation Testing
### Verify Log Rotation Settings
**Application log rotation** (100MB max, 30 day retention):
```bash
ls -lh logs/app.log*
# Should show app.log and rotated files (app.log.1, app.log.2, etc.)
```
**Access log rotation** (500MB max, 90 day retention):
```bash
ls -lh logs/access.log*
# Should show access.log and rotated files
```
### Trigger Log Rotation (Manual Test)
Generate large number of log entries:
```bash
# Generate 1000 requests (will create logs)
for i in {1..1000}; do
curl -s -H "token: test-token-abc123" http://localhost:3000/api/v1/users > /dev/null
done
```
**Check log file sizes**:
```bash
du -h logs/
```
**Note**: Rotation happens automatically when size limit is reached. Old files are compressed (`.gz`) if compression is enabled.
---
## Troubleshooting
### Problem: Server won't start
**Check**:
1. Port 3000 is not already in use: `lsof -i :3000`
2. Configuration file is valid YAML: `cat configs/config.yaml`
3. Logs directory exists: `ls -ld logs/`
### Problem: Redis connection fails
**Check**:
1. Redis is running: `redis-cli ping`
2. Redis address in config is correct: `localhost:6379`
3. Redis authentication (if password is set)
### Problem: Token validation always fails
**Check**:
1. Token exists in Redis: `redis-cli GET "auth:token:your-token"`
2. Token hasn't expired (check TTL): `redis-cli TTL "auth:token:your-token"`
3. Token key format is correct: `auth:token:{token_string}`
### Problem: Logs not appearing
**Check**:
1. Log directory has write permissions: `ls -ld logs/`
2. Log level in config: `info` or `debug`
3. Logger is properly initialized (check server startup logs)
### Problem: Configuration hot reload not working
**Check**:
1. Configuration file path is correct
2. File system notifications are working (fsnotify)
3. Server logs show config change events
4. New configuration is valid (invalid config is rejected)
---
## Development Workflow
### 1. Code Changes
Make changes to middleware or configuration code.
### 2. Run Tests
```bash
# Run all tests
go test ./...
# Run tests with coverage
go test -cover ./...
# Run specific test
go test -v ./internal/middleware -run TestKeyAuth
```
### 3. Format Code
```bash
# Format all code
go fmt ./...
# Check formatting
gofmt -l .
```
### 4. Static Analysis
```bash
# Run go vet
go vet ./...
# Run golangci-lint (if installed)
golangci-lint run
```
### 5. Build and Test
```bash
# Build
go build -o bin/api cmd/api/main.go
# Test binary
./bin/api
```
---
## Environment-Specific Configurations
### Development (`configs/config.dev.yaml`)
```yaml
logging:
level: "debug" # More verbose logging
development: true # Pretty-printed logs (non-JSON)
middleware:
enable_auth: false # Optional: disable auth for easier testing
```
**Usage**:
```bash
export CONFIG_ENV=dev
go run cmd/api/main.go
```
### Staging (`configs/config.staging.yaml`)
```yaml
server:
address: ":8080"
redis:
address: "redis-staging.example.com:6379"
password: "staging-password"
logging:
level: "info"
middleware:
enable_rate_limiter: true
rate_limiter:
max: 1000
expiration: "1m"
```
### Production (`configs/config.prod.yaml`)
```yaml
server:
address: ":8080"
prefork: true # Multi-process mode for performance
redis:
address: "redis-prod.example.com:6379"
password: "prod-password"
pool_size: 50 # Larger pool for production
logging:
level: "warn" # Less verbose
development: false
middleware:
enable_rate_limiter: true
rate_limiter:
max: 5000
expiration: "1m"
storage: "redis" # Distributed rate limiting
```
---
## Next Steps
After verifying the middleware integration works:
1. **Run `/speckit.tasks`**: Generate implementation tasks
2. **Run `/speckit.implement`**: Execute implementation
3. **Write tests**: Unit and integration tests for all middleware
4. **Update documentation**: Add API endpoint examples
5. **Deploy to staging**: Test in staging environment
---
## Quick Reference
### Redis Commands
```bash
# Set token (expires in 1 hour)
redis-cli SETEX "auth:token:TOKEN" 3600 "USER_ID"
# Get token
redis-cli GET "auth:token:TOKEN"
# Check TTL
redis-cli TTL "auth:token:TOKEN"
# Delete token
redis-cli DEL "auth:token:TOKEN"
# List all tokens (careful in production!)
redis-cli KEYS "auth:token:*"
```
### Curl Examples
```bash
# Health check
curl http://localhost:3000/health
# With token
curl -H "token: TOKEN" http://localhost:3000/api/v1/users
# POST request
curl -X POST \
-H "token: TOKEN" \
-H "Content-Type: application/json" \
-d '{"name":"John","email":"john@example.com"}' \
http://localhost:3000/api/v1/users
# Show response headers
curl -i -H "token: TOKEN" http://localhost:3000/api/v1/users
```
### Log Tailing
```bash
# Tail application logs
tail -f logs/app.log | jq .
# Tail access logs
tail -f logs/access.log | jq .
# Filter by request ID
tail -f logs/app.log | grep "REQUEST_ID"
```

# Research: Fiber Middleware Integration
**Feature**: 001-fiber-middleware-integration
**Date**: 2025-11-10
**Phase**: 0 - Research & Discovery
## Overview
This document resolves technical unknowns and establishes best practices for integrating Fiber middleware with Viper configuration, Zap logging, and Redis authentication.
---
## 1. Viper Configuration Hot Reload
### Decision: Use fsnotify (Viper Native Watcher)
**Rationale**:
- Viper has built-in `WatchConfig()` method using fsnotify
- No polling overhead, event-driven file change detection
- Cross-platform support (Linux, macOS, Windows)
- Battle-tested in production environments
- Integrates seamlessly with Viper's config merge logic
**Implementation Pattern**:
```go
viper.WatchConfig()
viper.OnConfigChange(func(e fsnotify.Event) {
log.Info("Config file changed", zap.String("file", e.Name))
// Reload config atomically
newConfig := &Config{}
if err := viper.Unmarshal(newConfig); err != nil {
log.Error("Failed to reload config", zap.Error(err))
return // Keep existing config
}
// Validate new config
if err := newConfig.Validate(); err != nil {
log.Error("Invalid config", zap.Error(err))
return // Keep existing config
}
// Atomic swap using sync/atomic
atomic.StorePointer(&globalConfig, unsafe.Pointer(newConfig))
})
```
**Best Practices**:
- Use atomic pointer swap to avoid race conditions
- Validate configuration before applying
- Log reload events with success/failure status
- Keep existing config if new config is invalid
- Don't restart services (logger, Redis client) on every change - only update values
**Alternatives Considered**:
- Manual polling: Higher CPU overhead, added complexity
- Signal-based reload (SIGHUP): Requires manual triggering, not automatic
- Third-party config libraries (consul, etcd): Overkill for file-based config
---
## 2. Zap + Lumberjack Integration for Dual Log Files
### Decision: Two Separate Zap Logger Instances
**Rationale**:
- Clean separation of concerns (app logic vs HTTP access)
- Independent rotation policies (app.log: 100MB/30days, access.log: 500MB/90days)
- Different log levels (app: debug/info/error, access: info only)
- Easier to analyze and ship to different log aggregators
- Follows Go's simplicity principle - no complex routing logic
**Implementation Pattern**:
```go
// Application logger (app.log)
appCore := zapcore.NewCore(
zapcore.NewJSONEncoder(encoderConfig),
zapcore.AddSync(&lumberjack.Logger{
Filename: "logs/app.log",
MaxSize: 100, // MB
MaxBackups: 30,
MaxAge: 30, // days
Compress: true,
}),
zap.InfoLevel,
)
// Access logger (access.log)
accessCore := zapcore.NewCore(
zapcore.NewJSONEncoder(encoderConfig),
zapcore.AddSync(&lumberjack.Logger{
Filename: "logs/access.log",
MaxSize: 500, // MB
MaxBackups: 90,
MaxAge: 90, // days
Compress: true,
}),
zap.InfoLevel,
)
appLogger := zap.New(appCore, zap.AddCaller(), zap.AddStacktrace(zap.ErrorLevel))
accessLogger := zap.New(accessCore)
```
**Logger Usage**:
- **appLogger**: Business logic, errors, debug info, system events
- **accessLogger**: HTTP requests/responses only (method, path, status, duration, request ID)
**JSON Encoder Config**:
```go
encoderConfig := zapcore.EncoderConfig{
TimeKey: "timestamp",
LevelKey: "level",
NameKey: "logger",
CallerKey: "caller",
MessageKey: "message",
StacktraceKey: "stacktrace",
LineEnding: zapcore.DefaultLineEnding,
EncodeLevel: zapcore.LowercaseLevelEncoder,
EncodeTime: zapcore.ISO8601TimeEncoder, // RFC3339 format
EncodeDuration: zapcore.SecondsDurationEncoder,
EncodeCaller: zapcore.ShortCallerEncoder,
}
```
**Alternatives Considered**:
- Single logger with routing logic: Complex, error-prone, violates separation of concerns
- Log levels for separation: Doesn't solve retention/rotation policy differences
- Multiple cores in one logger: Still requires complex routing logic
---
## 3. Fiber Middleware Execution Order
### Decision: recover → requestid → logger → keyauth → limiter → handler
**Rationale**:
1. **recover** first: Must catch panics from all downstream middleware
2. **requestid** second: All logs need request ID, including auth failures
3. **logger** third: Log all requests including auth failures
4. **keyauth** fourth: Authentication before business logic
5. **limiter** fifth: Rate limit after auth (only count authenticated requests)
6. **handler** last: Business logic with all context available
**Fiber Middleware Registration**:
```go
app.Use(customRecover()) // Must be first
app.Use(fiber.New(fiber.Config{
Next: nil,
Generator: uuid.NewString, // UUID v4
}))
app.Use(customLogger(accessLogger))
app.Use(customKeyAuth(validator, appLogger))
// app.Use(customLimiter()) // Commented by default
app.Get("/api/v1/users", handler)
```
**Critical Insights**:
- Middleware executes in registration order (top to bottom)
- `recover` must be first to catch panics from all middleware
- `requestid` must be before logger to include ID in access logs
- Auth middleware should have access to request ID for security logs
- Rate limiter after auth = more accurate rate limiting per user/IP combo
**Alternatives Considered**:
- Auth before logger: Can't log auth failures with full context
- Rate limit before auth: Anonymous requests consume rate limit quota
- Request ID after logger: Access logs missing correlation IDs
---
## 4. Fiber keyauth Middleware Customization
### Decision: Wrap Fiber's keyauth with Custom Redis Validator
**Rationale**:
- Fiber's keyauth middleware provides token extraction from headers
- Custom validator function handles Redis token validation
- Clean separation: Fiber handles HTTP, validator handles business logic
- Easy to test validator independently
- Follows constitution's Handler → Service pattern
**Implementation Pattern**:
```go
// Validator service (pkg/validator/token.go)
type TokenValidator struct {
redis *redis.Client
logger *zap.Logger
}
func (v *TokenValidator) Validate(token string) (string, error) {
ctx, cancel := context.WithTimeout(context.Background(), 50*time.Millisecond)
defer cancel()
// Check Redis availability
if err := v.redis.Ping(ctx).Err(); err != nil {
return "", ErrRedisUnavailable // Fail closed
}
// Get user ID from token
userID, err := v.redis.Get(ctx, constants.RedisAuthTokenKey(token)).Result()
if err == redis.Nil {
return "", ErrInvalidToken
}
if err != nil {
return "", fmt.Errorf("redis get: %w", err)
}
return userID, nil
}
// Middleware wrapper (internal/middleware/auth.go)
func KeyAuth(validator *validator.TokenValidator, logger *zap.Logger) fiber.Handler {
return keyauth.New(keyauth.Config{
KeyLookup: "header:token",
Validator: func(c *fiber.Ctx, key string) (bool, error) {
userID, err := validator.Validate(key)
if err != nil {
logger.Warn("Token validation failed",
zap.String("request_id", c.Locals(constants.ContextKeyRequestID).(string)),
zap.Error(err),
)
return false, err
}
// Store user ID in context
c.Locals("user_id", userID)
return true, nil
},
ErrorHandler: func(c *fiber.Ctx, err error) error {
// Map errors to unified response format
switch err {
case keyauth.ErrMissingOrMalformedAPIKey:
return response.Error(c, 401, errors.CodeMissingToken, "Missing authentication token")
case ErrInvalidToken:
return response.Error(c, 401, errors.CodeInvalidToken, "Invalid or expired token")
case ErrRedisUnavailable:
return response.Error(c, 503, errors.CodeAuthServiceUnavailable, "Authentication service unavailable")
default:
return response.Error(c, 500, errors.CodeInternalError, "Internal server error")
}
},
})
}
```
**Best Practices**:
- Use context timeout for Redis operations (50ms)
- Fail closed when Redis unavailable (HTTP 503)
- Store user ID in Fiber context (`c.Locals`) for downstream handlers
- Log all auth failures with request ID for security auditing
- Use custom error types for different failure modes
**Alternatives Considered**:
- Direct Redis calls in middleware: Violates separation of concerns
- JWT tokens: Spec requires Redis validation, not stateless tokens
- Cache validation results: Security risk, defeats Redis TTL purpose
---
## 5. Redis Client Selection
### Decision: go-redis/redis/v8
**Rationale**:
- Most widely adopted Redis client in Go ecosystem (19k+ stars)
- Excellent performance and connection pooling
- Native context support for timeouts and cancellation
- Supports Redis Cluster, Sentinel, and standalone
- Active maintenance and community support
- Already compatible with Go 1.18+ (uses generics)
- Comprehensive documentation and examples
**Connection Pool Configuration**:
```go
rdb := redis.NewClient(&redis.Options{
Addr: "localhost:6379",
Password: "", // From config
DB: 0, // From config
PoolSize: 10, // Concurrent connections
MinIdleConns: 5, // Keep-alive connections
MaxRetries: 3, // Retry failed commands
DialTimeout: 5 * time.Second,
ReadTimeout: 3 * time.Second,
WriteTimeout: 3 * time.Second,
PoolTimeout: 4 * time.Second, // Wait for connection from pool
})
```
**Best Practices**:
- Use context with timeout for all Redis operations
- Check Redis availability with `Ping()` before critical operations
- Use `Get()` for simple token validation (O(1) complexity)
- Let Redis TTL handle token expiration (no manual cleanup)
- Monitor connection pool metrics in production
**Alternatives Considered**:
- **redigo**: Older, no context support, more manual connection management
- **rueidis**: Very fast but newer, less community adoption
- **Native Redis module**: Doesn't exist in Go standard library
---
## 6. UUID v4 Generation
### Decision: google/uuid (Already in go.mod)
**Rationale**:
- Already a dependency (via Fiber's uuid import)
- Official Google implementation, well-tested
- Simple API: `uuid.New()` or `uuid.NewString()`
- RFC 4122 compliant UUID v4 (random)
- No external dependencies
- Excellent performance (~1.5M UUIDs/sec)
**Implementation**:
```go
import "github.com/google/uuid"
// In requestid middleware config
fiber.New(fiber.Config{
Generator: uuid.NewString, // Returns string directly
})
// Or manual generation
requestID := uuid.NewString() // "550e8400-e29b-41d4-a716-446655440000"
```
**UUID v4 Characteristics**:
- 122 random bits (collision probability ~1 in 2^122)
- No need for special collision handling
- Compatible with distributed tracing (Jaeger, OpenTelemetry)
- Human-readable in logs and headers
**Alternatives Considered**:
- **crypto/rand + manual formatting**: Reinventing the wheel, error-prone
- **ULID**: Lexicographically sortable but not requested in spec
- **Standard library**: No UUID support in Go stdlib
---
## 7. Fiber Limiter Middleware
### Decision: Fiber Built-in Limiter with Memory Storage (Commented by Default)
**Rationale**:
- Fiber's limiter middleware supports multiple storage backends
- Memory storage sufficient for single-server deployment
- Redis storage available for multi-server deployment
- Per-IP rate limiting via client IP extraction
- Sliding window or fixed window algorithms available
**Implementation Pattern (Commented)**:
```go
// Rate limiter configuration (commented by default)
// Uncomment and configure per endpoint as needed
/*
app.Use("/api/v1/", limiter.New(limiter.Config{
Max: 100, // Max requests
Expiration: 1 * time.Minute, // Time window
KeyGenerator: func(c *fiber.Ctx) string {
return c.IP() // Rate limit by IP
},
LimitReached: func(c *fiber.Ctx) error {
return response.Error(c, 429, errors.CodeTooManyRequests, "Too many requests")
},
Storage: nil, // nil = in-memory, or redis storage for distributed
}))
*/
```
**Configuration Options**:
- **Max**: Number of requests allowed in time window (e.g., 100)
- **Expiration**: Time window duration (e.g., 1 minute)
- **KeyGenerator**: Function to extract rate limit key (IP, user ID, API key)
- **Storage**: Memory (default) or Redis for distributed rate limiting
- **LimitReached**: Custom error handler returning unified response format
**Enabling Rate Limiter**:
1. Uncomment middleware registration in `main.go`
2. Configure limits per endpoint or globally
3. Choose storage backend (memory for single server, Redis for cluster)
4. Update documentation with rate limit values
5. Monitor rate limit hits in logs
**Best Practices**:
- Apply rate limits per endpoint (different limits for read vs write)
- Use Redis storage for multi-server deployments
- Log rate limit violations for abuse detection
- Return `Retry-After` header in 429 responses
- Configure different limits for authenticated vs anonymous requests
**Alternatives Considered**:
- **Third-party rate limiter**: Added complexity, Fiber's built-in sufficient
- **Token bucket algorithm**: Fiber supports sliding window, simpler to configure
- **Rate limit before auth**: Spec requires after auth, per-IP basis
---
## 8. Graceful Shutdown Pattern
### Decision: Context-Based Cancellation with Shutdown Hook
**Rationale**:
- Go's context package provides clean cancellation propagation
- Fiber supports graceful shutdown with timeout
- Config watcher must stop before application exits
- Prevents goroutine leaks and incomplete operations
**Implementation Pattern**:
```go
func main() {
// Create root context with cancellation
ctx, cancel := context.WithCancel(context.Background())
defer cancel()
// Initialize components with context
cfg := config.Load()
go config.Watch(ctx, cfg) // Pass context to watcher
app := setupApp(cfg)
// Graceful shutdown signal handling
quit := make(chan os.Signal, 1)
signal.Notify(quit, os.Interrupt, syscall.SIGTERM)
go func() {
if err := app.Listen(cfg.Server.Address); err != nil {
log.Fatal("Server failed", zap.Error(err))
}
}()
<-quit // Block until signal
log.Info("Shutting down server...")
cancel() // Cancel context (stops config watcher)
if err := app.ShutdownWithTimeout(30 * time.Second); err != nil {
log.Error("Forced shutdown", zap.Error(err))
}
log.Info("Server stopped")
}
```
**Watcher Cancellation**:
```go
func Watch(ctx context.Context, cfg *Config) {
viper.WatchConfig()
viper.OnConfigChange(func(e fsnotify.Event) {
select {
case <-ctx.Done():
return // Stop processing config changes
default:
// Reload config logic
}
})
<-ctx.Done() // Block until cancelled
log.Info("Config watcher stopped")
}
```
**Best Practices**:
- Use `context.Context` for all long-running goroutines
- Set reasonable shutdown timeout (30 seconds)
- Close resources in defer statements
- Log shutdown progress
- Flush logs before exit (`logger.Sync()`)
---
## 9. Testing Strategies
### Decision: Table-Driven Tests with Mock Redis
**Rationale**:
- Table-driven tests are Go idiomatic (endorsed by Go team)
- Mock Redis avoids external dependencies in unit tests
- Integration tests use testcontainers for real Redis
- Middleware testing requires Fiber test context
**Unit Test Pattern (Token Validator)**:
```go
func TestTokenValidator_Validate(t *testing.T) {
tests := []struct {
name string
token string
setupMock func(*mock.Redis)
wantUser string
wantErr error
}{
{
name: "valid token",
token: "valid-token-123",
setupMock: func(m *mock.Redis) {
m.On("Get", mock.Anything, "auth:token:valid-token-123").
Return(redis.NewStringResult("user-456", nil))
},
wantUser: "user-456",
wantErr: nil,
},
{
name: "expired token",
token: "expired-token",
setupMock: func(m *mock.Redis) {
m.On("Get", mock.Anything, "auth:token:expired-token").
Return(redis.NewStringResult("", redis.Nil))
},
wantUser: "",
wantErr: ErrInvalidToken,
},
// More cases...
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
mockRedis := &mock.Redis{}
tt.setupMock(mockRedis)
validator := NewTokenValidator(mockRedis, zap.NewNop())
userID, err := validator.Validate(tt.token)
if err != tt.wantErr {
t.Errorf("got error %v, want %v", err, tt.wantErr)
}
if userID != tt.wantUser {
t.Errorf("got userID %s, want %s", userID, tt.wantUser)
}
mockRedis.AssertExpectations(t)
})
}
}
```
**Integration Test Pattern (Middleware Chain)**:
```go
func TestMiddlewareChain(t *testing.T) {
// Start testcontainer Redis
redisContainer, err := testcontainers.GenericContainer(ctx,
testcontainers.GenericContainerRequest{
ContainerRequest: testcontainers.ContainerRequest{
Image: "redis:7-alpine",
ExposedPorts: []string{"6379/tcp"},
},
Started: true,
})
require.NoError(t, err)
defer redisContainer.Terminate(ctx)
// Setup app with middleware
app := setupTestApp(redisContainer)
// Test cases
tests := []struct {
name string
setupToken func(redis *redis.Client)
headers map[string]string
expectedStatus int
expectedCode int
}{
{
name: "valid request with token",
setupToken: func(rdb *redis.Client) {
rdb.Set(ctx, "auth:token:valid-token", "user-123", 1*time.Hour)
},
headers: map[string]string{"token": "valid-token"},
expectedStatus: 200,
expectedCode: 0,
},
// More cases...
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
if tt.setupToken != nil {
tt.setupToken(redisClient)
}
req := httptest.NewRequest("GET", "/api/v1/test", nil)
for k, v := range tt.headers {
req.Header.Set(k, v)
}
resp, err := app.Test(req)
require.NoError(t, err)
assert.Equal(t, tt.expectedStatus, resp.StatusCode)
// Parse response body and check code
var body response.Response
json.NewDecoder(resp.Body).Decode(&body)
assert.Equal(t, tt.expectedCode, body.Code)
})
}
}
```
**Testing Best Practices**:
- Use `testing` package (no third-party test frameworks)
- Mock external dependencies (Redis) in unit tests
- Use real services in integration tests (testcontainers)
- Test helpers marked with `t.Helper()`
- Parallel tests when possible (`t.Parallel()`)
- Clear test names describing scenario
- Assert expected errors, not just success cases
---
## 10. Middleware Error Handling
### Decision: Custom ErrorHandler for Unified Response Format
**Rationale**:
- Fiber middleware returns errors, not HTTP responses
- ErrorHandler translates errors to unified response format
- Consistent error structure across all middleware
- Proper HTTP status codes and error codes
**Pattern**:
```go
// In each middleware config
ErrorHandler: func(c *fiber.Ctx, err error) error {
// Map error to response
code, status, msg := mapError(err)
return response.Error(c, status, code, msg)
}
// Centralized error mapping
func mapError(err error) (code, status int, msg string) {
switch {
case errors.Is(err, ErrMissingToken):
return errors.CodeMissingToken, 401, "Missing authentication token"
case errors.Is(err, ErrInvalidToken):
return errors.CodeInvalidToken, 401, "Invalid or expired token"
case errors.Is(err, ErrRedisUnavailable):
return errors.CodeAuthServiceUnavailable, 503, "Authentication service unavailable"
case errors.Is(err, ErrTooManyRequests):
return errors.CodeTooManyRequests, 429, "Too many requests"
default:
return errors.CodeInternalError, 500, "Internal server error"
}
}
```

## Clarifications
### Session 2025-11-10
- Q: What specific types of logs should the Zap + Lumberjack integration handle? → A: Both application logs and HTTP access logs, with configurable separation into different files (app.log, access.log) to enable independent retention policies and analysis workflows.
- Q: When Redis is unavailable during token validation (FR-016), what should the authentication behavior be? → A: Fail closed: All authentication requests fail immediately when Redis is unavailable (return HTTP 503)
- Q: What data structure and content should be stored in Redis for authentication tokens? → A: Token as key only (simple existence check): Store tokens as Redis keys with user ID as value, using Redis TTL for expiration
- Q: What identifier should the rate limiter use to track and enforce request limits? → A: Per-IP address: Rate limit based on client IP address with configurable requests per time window (e.g., 100 req/min per IP)
- Q: What format should be used for generating unique request IDs in the requestid middleware? → A: UUID v4 (random): Standard UUID format for maximum compatibility with distributed tracing systems and log aggregation tools
## User Scenarios & Testing
### User Story 1 - Configuration Hot Reload (Priority: P1)
When system administrators or DevOps engineers modify application configuration files (such as server ports, database connections, log levels), the system should automatically detect and apply these changes without requiring a service restart, ensuring zero-downtime configuration updates.
**Why this priority**: Configuration management is foundational for all other features. Without proper configuration loading and hot reload capability, the system cannot support runtime adjustments, which is critical for production environments.
**Independent Test**: Can be fully tested by modifying a configuration value in the config file and verifying the system picks up the new value within seconds without restart, delivering immediate configuration flexibility.
**Acceptance Scenarios**:
1. **Given** the system is running with initial configuration, **When** an administrator updates the log level in the config file, **Then** the system detects the change within 5 seconds and applies the new log level to all subsequent log entries
2. **Given** the system is running, **When** configuration file contains invalid syntax, **Then** the system logs a warning and continues using the previous valid configuration
3. **Given** configuration hot reload is enabled, **When** multiple configuration parameters are changed simultaneously, **Then** all changes are applied atomically without partial updates
---
### User Story 2 - Structured Logging and Log Rotation (Priority: P1)
When the system processes requests and business operations, all events, errors, and debugging information should be recorded in structured JSON format with automatic log file rotation based on size and time, ensuring comprehensive audit trails without disk space exhaustion. The system maintains separate log files for application logs (app.log) and HTTP access logs (access.log) with independent retention policies.
**Why this priority**: Logging is essential for debugging, monitoring, and compliance. Structured logs enable efficient querying and analysis, while automatic rotation prevents operational issues. Separating application and access logs allows for different retention policies and analysis workflows.
**Independent Test**: Can be fully tested by generating various log events and verifying they appear in structured JSON format in the appropriate files, and that log files rotate when size/time thresholds are reached, delivering production-ready logging capability.
**Acceptance Scenarios**:
1. **Given** the system is processing requests, **When** any application operation occurs, **Then** logs are written to app.log in JSON format containing timestamp, level, message, request ID, and contextual data
2. **Given** the system is processing HTTP requests, **When** requests complete, **Then** access logs are written to access.log with request method, path, status, duration, and request ID
3. **Given** a log file reaches the configured size limit, **When** new log entries are generated, **Then** the current log file is archived and a new log file is created
4. **Given** log retention is configured for 30 days for application logs and 90 days for access logs, **When** log files exceed the retention period, **Then** older log files are automatically removed according to their respective policies
5. **Given** multiple log levels are configured (debug, info, warn, error), **When** logging at different levels, **Then** only messages at or above the configured level are written
---
### User Story 3 - Unified API Response Format (Priority: P1)
When API consumers (frontend applications, mobile apps, third-party integrations) make requests to any endpoint, they should receive responses in a consistent JSON structure containing status code, data payload, and message, regardless of success or failure, enabling predictable error handling and data parsing.
**Why this priority**: Consistent response format is critical for API consumers to reliably parse responses. Without this, every endpoint integration becomes custom work, increasing development time and bug potential.
**Independent Test**: Can be fully tested by calling any endpoint (successful or failed) and verifying the response structure matches the defined format with appropriate code, data, and message fields, delivering immediate API consistency.
**Acceptance Scenarios**:
1. **Given** a valid API request, **When** the request succeeds, **Then** the response follows the unified format defined in FR-007 with code 0 and appropriate data
2. **Given** an invalid API request, **When** validation fails, **Then** the response follows the unified format defined in FR-007 with appropriate error code and null data
3. **Given** any API endpoint, **When** processing completes, **Then** the response structure always includes all three required fields (code, data, msg) as specified in FR-007
4. **Given** list/array data is returned, **When** the response is generated, **Then** the data field contains an array instead of an object, maintaining the unified format structure
---
### User Story 4 - Request Logging and Tracing (Priority: P2)
When HTTP requests arrive at the system, each request should be assigned a unique identifier and all request details (method, path, duration, status) should be logged, enabling request tracking across distributed components and performance analysis.
**Why this priority**: Request logging provides visibility into system usage patterns and performance. The unique request ID enables correlation of logs across services for troubleshooting.
**Independent Test**: Can be fully tested by making multiple concurrent requests and verifying each has a unique request ID in logs and response headers, and that request metrics are captured, delivering complete request observability.
**Acceptance Scenarios**:
1. **Given** an HTTP request arrives, **When** it enters the system, **Then** a unique request ID in UUID v4 format (e.g., "550e8400-e29b-41d4-a716-446655440000") is generated and added to the request context
2. **Given** a request is being processed, **When** any logging occurs during that request, **Then** the request ID is automatically included in log entries
3. **Given** a request completes, **When** the response is sent, **Then** the request ID is included in response headers (X-Request-ID) and a summary log entry records method, path, status, and duration
4. **Given** multiple concurrent requests, **When** processed simultaneously, **Then** each request maintains its own unique UUID v4 request ID without collision
---
### User Story 5 - Automatic Error Recovery (Priority: P2)
When unexpected errors or panics occur during request processing, the system should automatically recover from the failure, log detailed error information, return an appropriate error response to the client, and continue serving subsequent requests without crashing.
**Why this priority**: Error recovery prevents cascading failures and ensures service availability. A single panic should not bring down the entire application.
**Independent Test**: Can be fully tested by triggering a controlled panic in a handler and verifying the system returns an error response, logs the panic details, and continues processing subsequent requests normally, delivering fault tolerance.
**Acceptance Scenarios**:
1. **Given** a request handler panics, **When** the panic occurs, **Then** the middleware recovers, logs the panic stack trace, and returns HTTP 500 with error details
2. **Given** a panic is recovered, **When** subsequent requests arrive, **Then** they are processed normally without any impact from the previous panic
3. **Given** a panic includes error details, **When** logged, **Then** the log entry contains the panic message, stack trace, request ID, and request details
---
### User Story 6 - Token-Based Authentication (Priority: P2)
When external clients make API requests, they must provide a valid authentication token in the request header, which the system validates against stored tokens in Redis cache, ensuring only authorized requests can access protected resources.
**Why this priority**: Authentication is essential for security but depends on the foundational components (config, logging, response format) being in place first.
**Independent Test**: Can be fully tested by making requests with valid/invalid/missing tokens and verifying that valid tokens grant access while invalid ones are rejected with appropriate error codes, delivering access control capability.
**Acceptance Scenarios**:
1. **Given** a request to a protected endpoint, **When** the "token" header is missing, **Then** the system returns HTTP 401 with `{"code": 1001, "data": null, "msg": "缺失认证令牌"}`
2. **Given** a request with a token, **When** the token exists as a key in Redis, **Then** the system retrieves the user ID from the value and allows the request to proceed with user context
3. **Given** a request with a token, **When** the token does not exist in Redis (either never created or TTL expired), **Then** the system returns HTTP 401 with `{"code": 1002, "data": null, "msg": "令牌无效或已过期"}`
4. **Given** Redis is unavailable, **When** token validation is attempted, **Then** the system immediately fails closed, logs the Redis connection error, and returns HTTP 503 with `{"code": 1004, "data": null, "msg": "认证服务不可用"}` without attempting fallback mechanisms
---
### User Story 7 - Rate Limiting Configuration (Priority: P3)
The system should provide configurable IP-based rate limiting capabilities that can restrict the number of requests from a specific client IP address within a time window, with the functionality initially implemented but disabled by default, allowing future activation based on specific endpoint requirements.
**Why this priority**: Rate limiting is important for production but not critical for initial deployment. It can be activated later when traffic patterns are better understood.
**Independent Test**: Can be fully tested by enabling the limiter configuration, making repeated requests from the same IP exceeding the limit, and verifying that excess requests are rejected with rate limit error messages, delivering DoS protection capability when needed.
**Acceptance Scenarios**:
1. **Given** rate limiting is configured and enabled for an endpoint with 100 requests per minute per IP, **When** a client IP exceeds the request limit within the time window, **Then** subsequent requests from that IP return HTTP 429 with `{"code": 1003, "data": null, "msg": "请求过于频繁"}`
2. **Given** the rate limit time window expires, **When** new requests arrive from the same client IP, **Then** the request counter resets and requests are allowed again
3. **Given** rate limiting is disabled (default), **When** any number of requests arrive, **Then** all requests are processed without rate limit checks
4. **Given** rate limiting is enabled, **When** requests arrive from different IP addresses, **Then** each IP address has its own independent request counter and limit
---
### Edge Cases
- What happens when the configuration file is deleted while the system is running? (System should log error and continue with current configuration)
- What happens when Redis connection is lost during token validation? (System immediately fails closed, returns HTTP 503 with code 1004, logs connection failure, and does not attempt any fallback authentication)
- What happens when log directory is not writable?
- **At startup**: System MUST fail immediately with exit code 1 and clear error message to stderr before listening on any port (e.g., "Fatal: Cannot write to log directory 'logs/': permission denied")
- **At runtime**: If log directory becomes non-writable after successful startup, system MUST log error to stderr, continue serving requests but return HTTP 503 on health check endpoint until log directory becomes writable again
- What happens when a request ID collision occurs? (With UUID v4, collision probability is negligible: ~1 in 2^122; no special handling needed)
- What happens when configuration hot reload occurs during active request processing? (Configuration changes should not affect in-flight requests)
- What happens when log rotation occurs while writing a log entry? (Log rotation should be atomic and not lose log entries)
- What happens when invalid configuration values are provided (e.g., negative numbers for limits)? (System should validate config on load and reject invalid values with clear error messages)
## Requirements
### Functional Requirements
- **FR-001**: System MUST load configuration from files using Viper configuration library
- **FR-002**: System MUST support hot reload of configuration files using fsnotify-based file system event detection (immediate notification on file changes), with configuration changes applied within 5 seconds of file modification and without service restart. The 5-second window includes file event detection, validation, and atomic configuration swap.
- **FR-003**: System MUST validate configuration values on load and reject invalid configurations with descriptive error messages following the format: `"Invalid configuration: {field_path}: {error_reason} (current value: {value}, expected: {constraint})"`. Validation categories include:
- **Type validation**: All fields match expected types (string, int, bool, duration)
- **Range validation**: Numeric values within acceptable ranges (e.g., server.port: 1024-65535, log.max_size: 1-1000 MB)
- **Required fields**: server.host, server.port, redis.addr, logging.app_log_path, logging.access_log_path
- **Format validation**: Durations use Go duration format (e.g., "5m", "30s"), file paths are absolute or relative valid paths
- **Example error**: `"Invalid configuration: server.port: port number out of range (current value: 80, expected: 1024-65535)"`
- **Complete validation rules**: See data-model.md "Configuration Validation Rules" section for comprehensive field-by-field validation constraints
- **FR-004**: System MUST use Zap structured logging for all application logs with log rotation via Lumberjack.v2 and configurable log levels. The system maintains two independent Zap logger instances:
- **appLogger**: For application-level logs (business logic, errors, middleware events, debug info)
- **accessLogger**: For HTTP access logs (request/response details per FR-011)
- Each logger instance has separate Lumberjack rotation configuration for independent file management
- **FR-004a**: System MUST separate application logs (app.log) and HTTP access logs (access.log) into different files with independent configuration
- **FR-005**: System MUST rotate log files automatically using Lumberjack.v2 based on configurable size and age parameters for both application and access logs
- **FR-006**: System MUST retain log files according to configured retention policy and automatically remove expired logs, with separate retention settings for application and access logs. Retention policy is specified in days (integer) and configured via config file (e.g., `logging.app_log_max_age: 30` for 30-day retention of app.log, `logging.access_log_max_age: 90` for 90-day retention of access.log). Implemented via Lumberjack MaxAge parameter.
- **FR-007**: All API responses MUST follow the unified format: `{"code": [number], "data": [object/array/null], "msg": [string]}`. Examples:
- **Success response**: `{"code": 0, "data": {...}, "msg": "success"}`
- **Error response**: `{"code": [error_code], "data": null, "msg": "[error description]"}`
- **List response**: `{"code": 0, "data": [...], "msg": "success"}`
- The response structure always includes all three fields (code, data, msg) regardless of success or failure
- **FR-008**: System MUST assign a unique request ID to every incoming HTTP request using requestid middleware
- **FR-008a**: Request IDs MUST be generated using UUID v4 format for maximum compatibility with distributed tracing systems and log aggregation tools
- **FR-009**: System MUST include the request ID in all log entries associated with that request
- **FR-010**: System MUST include the request ID in HTTP response headers for client-side tracing
- **FR-011**: System MUST log all HTTP requests with method, path, status code, duration, and request ID using logger middleware. Access logs written to access.log MUST use structured JSON format with fields: timestamp (ISO 8601), level, request_id, method, path, status, duration_ms, ip, user_agent, and user_id (if authenticated). See data-model.md "Access Log Entry Format" for complete schema definition.
- **FR-012**: System MUST automatically recover from panics during request processing using recover middleware
- **FR-013**: When a panic is recovered, system MUST log the full stack trace and error details
- **FR-014**: When a panic is recovered, system MUST return HTTP 500 with unified error response format. Response format: `{"code": 1000, "data": null, "msg": "服务器内部错误"}`. The panic error message detail level MUST be configurable via code constant (not config file) to support different deployment environments:
- **Detailed mode** (default for development): Include sanitized panic message in response.msg (e.g., `"服务器内部错误: runtime error: invalid memory address"`)
- **Simple mode** (for production): Return generic message only (`"服务器内部错误"`)
- **Configuration**: Define constant in `pkg/constants/constants.go` as `const PanicResponseDetailLevel = "detailed"` or `"simple"`, easily changeable by developers before deployment
- **Security**: Full stack trace ALWAYS logged to app.log only, NEVER included in HTTP response regardless of mode
- All response messages MUST use Chinese, not English
- **FR-015**: System MUST validate authentication tokens from the "token" request header using keyauth middleware
- **FR-016**: System MUST check token validity by verifying existence in Redis cache using token string as key
- **FR-016a**: System MUST store tokens in Redis as simple key-value pairs with token as key and user ID as value, using Redis TTL for expiration management
- **FR-016b**: When Redis is unavailable during token validation, system MUST fail closed and return HTTP 503 immediately without fallback or caching mechanisms
- **FR-017**: System MUST return HTTP 401 with appropriate error code and message when token is missing or invalid
- **FR-018**: System MUST provide configurable IP-based rate limiting capability using limiter middleware
- **FR-018a**: Rate limiting MUST track request counts per client IP address with configurable limits (requests per time window). Default configuration: 30 requests per minute per IP. Supported time units: second (s), minute (m), hour (h). Configuration example in config file: `limiter.max: 30, limiter.window: 1m`
- **FR-018b**: When rate limit is exceeded, system MUST return HTTP 429 with code 1003 and appropriate error message
- **FR-019**: Rate limiting implementation MUST be provided but disabled by default in initial deployment
- **FR-020**: System MUST include documentation on how to configure and enable rate limiting per endpoint with example configurations. Documentation MUST be created as a separate file `docs/rate-limiting.md` containing:
- **Configuration parameters**: Detailed explanation of `max`, `expiration`, and `storage` settings
- **Per-endpoint setup**: How to enable/disable rate limiting for specific routes or globally
- **Code examples**: Complete examples showing how to uncomment and configure the limiter middleware in `cmd/api/main.go`
- **Testing guide**: Step-by-step instructions with curl commands to test rate limiting behavior
- **Storage options**: Comparison of memory vs Redis storage backends with use cases
- **Common patterns**: Examples for different scenarios (public API, admin endpoints, webhook receivers)
- **FR-021**: System MUST use consistent error codes across all error scenarios with bilingual (Chinese/English) support
- **FR-022**: Configuration MUST support different environments (development, staging, production) with separate config files

- [x] All configuration uses Viper
**Architecture Requirements**:
- [x] Implementation follows Handler → Service → Store → Model layers (applies to auth token validation)
- [x] Dependencies injected via Service/Store structs
- [x] Unified error codes defined in `pkg/errors/`
- [x] Unified API responses via `pkg/response/`
- [x] All constants defined in `pkg/constants/` (no magic numbers/strings)

- [x] Non-realtime operations delegated to async tasks (if applicable)
**Testing Requirements**:
- [x] Unit tests for all Service layer business logic
- [x] Integration tests for all API endpoints
- [x] Tests are independent and use mocks/testcontainers
- [x] Target coverage: 70%+ overall, 90%+ for core business logic
### Key Entities
- **Configuration**: Represents application configuration settings including server parameters, database connections, Redis settings, logging configuration (with separate settings for app.log and access.log including independent rotation and retention policies), and middleware settings. Supports hot reload capability to apply changes without restart.
- **AuthToken**: Represents an authentication token stored in Redis cache as a simple key-value pair. The token string is used as the Redis key, and the user ID is stored as the value. Token expiration is managed via Redis TTL mechanism. This structure enables O(1) existence checks for authentication validation.
- **Request Context**: Represents the execution context of an HTTP request, containing unique request ID (UUID v4 format), authentication information (user ID from token validation), request start time, and other metadata used for logging and tracing.
- **Log Entry**: Represents a structured log record containing timestamp, severity level, message, request ID, user context, and additional contextual fields, written in JSON format.
- **Rate Limit State**: Represents the current request count and time window for a specific client IP address, used to enforce per-IP rate limiting policies. Tracks remaining quota and window reset time for each unique IP.
## Success Criteria
### Measurable Outcomes
- **SC-001**: System administrators can modify any configuration value in the config file and see it applied within 5 seconds (file event detection + validation + atomic swap) without service restart, verified by observing the configuration change take effect (e.g., log level change reflected in subsequent log entries)
- **SC-002**: All API responses follow the unified `{code, data, msg}` structure with 100% consistency across all endpoints
- **SC-003**: Every HTTP request generates a unique UUID v4 request ID that appears in the X-Request-ID response header and all associated log entries
- **SC-004**: System continues processing new requests within 100ms after recovering from a panic, with zero downtime
- **SC-005**: Log files automatically rotate when reaching configured size limits (e.g., 100MB) without manual intervention
- **SC-006**: Invalid authentication tokens are rejected within 50ms with clear error messages, preventing unauthorized access
- **SC-007**: All logs are written in valid JSON format that can be parsed by standard log aggregation tools without errors
- **SC-008**: 100% of HTTP requests are logged with method, path, status, duration, and request ID for complete audit trail
- **SC-009**: Rate limiting (when enabled) successfully blocks requests exceeding configured limits within the time window with appropriate error responses
- **SC-010**: System successfully loads configuration from different environment-specific files (dev, staging, prod) based on environment variable

## Dependencies & Execution Order
### Phase Dependencies
1. **Setup (Phase 1)**: No dependencies - start immediately
2. **Foundational (Phase 2)**: Depends on Setup (Phase 1) - BLOCKS all user stories
3. **User Stories (Phases 3-9)**: All depend on Foundational (Phase 2) completion
- US1, US2, US3 can proceed in parallel (independent)
- US4 depends on US2 (needs logger)
- US5 can proceed in parallel with others
- US6 depends on US3 (needs response format)
- US7 depends on US3 (needs response format)
4. **Polish (Phase 10)**: Depends on all desired user stories being complete
### User Story Dependencies
```
Foundational (Phase 2) - MUST COMPLETE FIRST
├─→ US1: Config Hot Reload (independent)
├─→ US2: Logging (independent)
├─→ US3: Response Format (independent)
│
├─→ US4: Request Tracing (depends on US2: logger)
├─→ US5: Error Recovery (independent)
│
├─→ US6: Authentication (depends on US3: response format)
└─→ US7: Rate Limiting (depends on US3: response format)
```
### Within Each User Story
- Tests MUST be written FIRST and FAIL before implementation
- Models/structures before services
- Services before middleware
- Middleware before registration in main.go
- Core implementation before integration
### Parallel Opportunities
**Phase 1 (Setup)**: All tasks T002-T007 marked [P] can run in parallel
**Phase 2 (Foundational)**:
- T012 (dev/staging/prod configs) can run in parallel with others
- T013-T016 (logging) can run in parallel as group
- These are independent file operations
**Phase 3-9 (User Stories)**:
- After Foundational completes, these can start in parallel:
- US1: T018-T025 (config hot reload)
- US2: T026-T033 (logging)
- US3: T034-T042 (response format)
- US5: T052-T060 (error recovery)
- After US2 completes:
- US4: T043-T051 (request tracing)
- After US3 completes:
- US6: T061-T081 (authentication)
- US7: T082-T091 (rate limiting)
**Phase 10 (Polish)**: Many tasks marked [P] can run in parallel (documentation, linting, etc.)
---
## Parallel Execution Examples
### Example 1: Setup Phase (All Parallel)
```bash
# Launch all setup tasks together (different files):
Task T002: "Setup unified error codes in pkg/errors/codes.go"
Task T003: "Setup custom error types in pkg/errors/errors.go"
Task T004: "Setup unified response structure in pkg/response/response.go"
Task T005: "Setup response code constants in pkg/response/codes.go"
Task T006: "Setup business constants in pkg/constants/constants.go"
Task T007: "Setup Redis key generation functions in pkg/constants/redis.go"
```
### Example 2: User Story Tests (Parallel within Story)
```bash
# US6 unit tests - all can run in parallel:
Task T061: "Unit test for TokenValidator with valid token"
Task T062: "Unit test for expired/invalid token"
Task T063: "Unit test for Redis unavailable"
Task T064: "Unit test for context timeout"
# US6 integration tests - all can run in parallel:
Task T065: "Integration test with valid token"
Task T066: "Integration test for missing token"
Task T067: "Integration test for invalid token"
Task T068: "Integration test for Redis down"
```
### Example 3: Independent User Stories (After Foundation)
```bash
# After Phase 2 completes, these can all start in parallel:
Agent 1: Work on US1 (Config Hot Reload) - T018 through T025
Agent 2: Work on US2 (Logging) - T026 through T033
Agent 3: Work on US3 (Response Format) - T034 through T042
Agent 4: Work on US5 (Error Recovery) - T052 through T060
```

## Implementation Strategy
### MVP First (Minimum Viable Product)
**Recommendation**: Complete Phases 1-5 (Setup + Foundation + US1 + US2 + US3) for MVP
This delivers:
- Configuration hot reload (US1)
- Production logging (US2)
- API response consistency (US3)
Then deploy and validate before adding authentication and other features.
### Incremental Delivery Roadmap
1. **Foundation** (Phases 1-2): ~2-3 days
- Setup + Foundational infrastructure
- **Deliverable**: Basic Fiber app with config, logging, response structure
2. **MVP** (Phases 3-5): ~2-3 days
- US1: Config hot reload
- US2: Logging with rotation
- US3: Unified responses
- **Deliverable**: Production-ready foundation with observability
3. **Observability+** (Phases 6-7): ~2-3 days
- US4: Request tracing
- US5: Error recovery
- **Deliverable**: Complete observability and fault tolerance
4. **Security** (Phase 8): ~2-3 days
- US6: Authentication
- **Deliverable**: Secured API with Redis token validation
5. **Production Hardening** (Phases 9-10): ~2-3 days
- US7: Rate limiting (optional)
- Polish and quality gates
- **Deliverable**: Production-ready system
**Total Estimated Time**: 10-15 days (single developer)
### Parallel Team Strategy
With 3 developers after Foundation completes:
- **Dev A**: US1 + US2 (Config + Logging) - Core infrastructure
- **Dev B**: US3 + US4 (Response + Tracing) - API foundation
- **Dev C**: US5 + US6 (Recovery + Auth) - Reliability + Security
Then converge for US7 and Polish.
**Estimated Time with Parallel Work**: 7-10 days

**Constitution Compliance**:
- ✅ All tasks follow Handler → Service → Store → Model pattern
- ✅ All Redis keys use generation functions (no hardcoded strings)
- ✅ All responses use unified format
- ✅ All error codes centralized
- ✅ Go idiomatic patterns (no Java-style anti-patterns)
- ✅ Explicit error handling throughout
- ✅ Context usage for timeouts and cancellation
---
## Next Steps
1. ✅ Tasks.md generated and validated
2. ⏳ Review task list with team
3. ⏳ Set up development environment (Go 1.25.1, Redis 7.x)
4. ⏳ Run `/speckit.implement` to begin implementation
5. ⏳ Start with Phase 1 (Setup) - all tasks can run in parallel
**Ready for Implementation**: Yes - all tasks are specific, have file paths, and follow constitution principles.
