## Context
|
||
|
||
Phase 4 完成了订单和支付流程,现在需要实现佣金计算。当终端用户购买套餐支付成功后,系统自动计算各级代理的佣金并入账。
|
||
|
||
**佣金来源**:
|
||
1. **成本价差收入**:每笔订单必触发,售价 - 成本价 = 代理收入
|
||
2. **一次性佣金**:满足触发条件时发放一次,每张卡/设备仅发放一次
|
||
3. **周期性梯度返佣**:已在 refactor-shop-package-allocation 中实现,本期不涉及
|
||
|
||
**一次性佣金的两种类型**:
|
||
- **固定一次性佣金**:充值达标后发放固定金额或比例(如首充≥100元返20元)
|
||
- **梯度一次性佣金**:根据系列销售业绩返不同佣金(如系列销售额≥5000元时首充返15元)
|
||
|
||
**核心业务逻辑**:
|
||
- **触发条件**:基于单张卡/设备的充值情况(首充或累计充值达标)
|
||
- **返佣金额**:基于该系列分配的累计销售业绩(销量或销售额)选择梯度档位
|
||
- **发放次数**:每张卡/设备仅发放一次(通过 first_commission_paid 标记)
|
||
- **统计来源**:使用 ShopSeriesCommissionStats 查询该系列分配的销售业绩
|
||
|
||
**与重构的关系**:
|
||
- refactor-shop-package-allocation 已实现 ShopSeriesCommissionStats 统计表(按 allocation_id 统计销售业绩)
|
||
- 一次性佣金复用该统计表,通过 allocation_id 查询该系列分配的累计销量/销售额
|
||
- 需要在 ShopSeriesAllocation 表新增一次性佣金配置字段
|
||
- 需要新增 ShopSeriesOneTimeCommissionTier 表存储梯度配置
|
||
|
||
**当前 CommissionRecord 模型过于复杂**(包含冻结/解冻字段),需要简化。
|
||
|
||
## Goals / Non-Goals
|
||
|
||
**Goals:**
|
||
- 简化 CommissionRecord 模型
|
||
- 实现成本价差收入计算(每笔订单)
|
||
- 实现一次性佣金触发(充值阈值)
|
||
- 佣金直接入账到店铺钱包
|
||
- 提供佣金记录查询和统计
|
||
|
||
**Non-Goals:**
|
||
- 不实现冻结/解冻机制
|
||
- 不实现长期佣金(号卡专用)
|
||
- 不实现梯度佣金统计(本期只做配置,统计后续优化)
|
||
- 不实现佣金审批流程
|
||
|
||
## Decisions
|
||
|
||
### 1. CommissionRecord 模型简化
|
||
|
||
**决策**:删除冻结相关字段,新增来源和关联字段
|
||
|
||
```go
|
||
// 简化后的 CommissionRecord
|
||
type CommissionRecord struct {
|
||
gorm.Model
|
||
BaseModel
|
||
ShopID uint // 店铺ID(佣金归属)
|
||
OrderID uint // 关联订单ID
|
||
IotCardID uint // 关联卡ID(可空)
|
||
DeviceID uint // 关联设备ID(可空)
|
||
CommissionSource string // 佣金来源: cost_diff-成本价差 one_time-一次性佣金 tier_bonus-梯度奖励
|
||
Amount int64 // 佣金金额(分)
|
||
BalanceAfter int64 // 入账后钱包余额(分)
|
||
Status int // 状态: 1-已入账 2-已失效
|
||
ReleasedAt *time.Time // 入账时间
|
||
Remark string // 备注
|
||
}
|
||
```
|
||
|
||
**删除字段**:
|
||
- `agent_id`(改用 shop_id)
|
||
- `rule_id`(不再关联复杂规则)
|
||
- `commission_type`(改用 commission_source)
|
||
- `unfrozen_at`、冻结相关状态
|
||
|
||
### 2. 佣金计算流程
|
||
|
||
**决策**:订单支付成功后异步计算
|
||
|
||
```
|
||
订单支付成功
|
||
↓
|
||
发送异步任务 (Asynq)
|
||
↓
|
||
佣金计算任务执行:
|
||
1. 获取订单信息
|
||
2. 遍历代理层级(从销售店铺到顶级)
|
||
3. 每级计算成本价差收入
|
||
4. 检查一次性佣金触发条件
|
||
5. 创建 CommissionRecord
|
||
6. 更新店铺钱包余额
|
||
7. 更新订单 commission_status
|
||
```
|
||
|
||
### 3. 成本价差收入计算
|
||
|
||
**决策**:各级代理按自己的成本价差计算
|
||
|
||
**计算规则**:
|
||
- 终端销售代理:收入 = 售价 - 自己的成本价
|
||
- 中间层级代理:收入 = 下级的成本价 - 自己的成本价
|
||
|
||
```go
|
||
func CalculateCostDiffCommission(order *Order) []CommissionRecord {
|
||
var records []CommissionRecord
|
||
|
||
// 获取销售店铺(终端销售的代理)
|
||
sellerShop := GetShop(order.SellerShopID)
|
||
sellerCostPrice := GetCostPrice(sellerShop.ID, order.PackageID)
|
||
|
||
// 终端销售代理的收入 = 售价 - 成本价
|
||
sellerProfit := order.TotalAmount - sellerCostPrice
|
||
if sellerProfit > 0 {
|
||
records = append(records, CommissionRecord{
|
||
ShopID: sellerShop.ID,
|
||
OrderID: order.ID,
|
||
CommissionSource: "cost_diff",
|
||
Amount: sellerProfit,
|
||
})
|
||
}
|
||
|
||
// 遍历上级代理链
|
||
childCostPrice := sellerCostPrice
|
||
currentShop := GetShop(sellerShop.ParentID)
|
||
|
||
for currentShop != nil {
|
||
// 获取当前店铺的成本价
|
||
myCostPrice := GetCostPrice(currentShop.ID, order.PackageID)
|
||
|
||
// 收入 = 下级成本价 - 自己成本价
|
||
profit := childCostPrice - myCostPrice
|
||
if profit > 0 {
|
||
records = append(records, CommissionRecord{
|
||
ShopID: currentShop.ID,
|
||
OrderID: order.ID,
|
||
CommissionSource: "cost_diff",
|
||
Amount: profit,
|
||
})
|
||
}
|
||
|
||
// 移动到上级
|
||
childCostPrice = myCostPrice
|
||
currentShop = GetShop(currentShop.ParentID)
|
||
}
|
||
|
||
return records
|
||
}
|
||
```
|
||
|
||
### 4. 一次性佣金数据结构
|
||
|
||
**决策**:在 ShopSeriesAllocation 新增配置字段 + 新增梯度表
|
||
|
||
#### 4.1 ShopSeriesAllocation 新增字段
|
||
|
||
```go
|
||
type ShopSeriesAllocation struct {
|
||
// ... 现有字段(base_commission, enable_tier_commission 等)
|
||
|
||
// 🆕 一次性佣金配置
|
||
EnableOneTimeCommission bool `gorm:"column:enable_one_time_commission;default:false;comment:是否启用一次性佣金"`
|
||
OneTimeCommissionType string `gorm:"column:one_time_commission_type;type:varchar(20);comment:类型:fixed-固定 tiered-梯度"`
|
||
OneTimeCommissionTrigger string `gorm:"column:one_time_commission_trigger;type:varchar(30);comment:触发条件:single_recharge-单次充值 accumulated_recharge-累计充值"`
|
||
OneTimeCommissionThreshold int64 `gorm:"column:one_time_commission_threshold;type:bigint;comment:最低阈值(分)"`
|
||
|
||
// 固定一次性佣金配置(type="fixed" 时使用)
|
||
OneTimeCommissionMode string `gorm:"column:one_time_commission_mode;type:varchar(20);comment:模式:fixed-固定金额 percent-百分比"`
|
||
OneTimeCommissionValue int64 `gorm:"column:one_time_commission_value;type:bigint;comment:佣金金额(分)或比例(千分比)"`
|
||
}
|
||
```
|
||
|
||
#### 4.2 新增 ShopSeriesOneTimeCommissionTier 表
|
||
|
||
```go
|
||
// 梯度一次性佣金配置
|
||
type ShopSeriesOneTimeCommissionTier struct {
|
||
gorm.Model
|
||
BaseModel
|
||
AllocationID uint `gorm:"column:allocation_id;not null;index;comment:系列分配ID"`
|
||
|
||
// 梯度判断配置(基于系列销售业绩)
|
||
TierType string `gorm:"column:tier_type;type:varchar(20);not null;comment:梯度类型:sales_count-销量 sales_amount-销售额"`
|
||
ThresholdValue int64 `gorm:"column:threshold_value;type:bigint;not null;comment:梯度阈值(销量或销售额分)"`
|
||
|
||
// 返佣配置
|
||
CommissionMode string `gorm:"column:commission_mode;type:varchar(20);not null;comment:返佣模式:fixed-固定金额 percent-百分比"`
|
||
CommissionValue int64 `gorm:"column:commission_value;type:bigint;not null;comment:返佣值(分或千分比)"`
|
||
|
||
Status int `gorm:"column:status;type:int;default:1;comment:状态:1-启用 2-停用"`
|
||
}
|
||
|
||
// TableName 指定表名
|
||
func (ShopSeriesOneTimeCommissionTier) TableName() string {
|
||
return "tb_shop_series_one_time_commission_tier"
|
||
}
|
||
```
|
||
|
||
**关键说明**:
|
||
- `TierType`: 梯度判断类型,与 ShopSeriesCommissionTier 的 tier_type 一致(sales_count 或 sales_amount)
|
||
- `ThresholdValue`: 系列销售业绩的阈值(如系列累计销售额≥5000元)
|
||
- 梯度判断使用 ShopSeriesCommissionStats 表中的统计数据(按 allocation_id 查询)
|
||
|
||
### 5. 一次性佣金触发逻辑
|
||
|
||
**决策**:两种触发类型 × 两种佣金类型,每张卡/设备只触发一次
|
||
|
||
#### 5.1 触发条件判断
|
||
|
||
```go
|
||
// 触发条件 A:单次充值 ≥ 阈值
|
||
func CheckSingleRecharge(order *Order, threshold int64) (bool, int64) {
|
||
triggered := order.TotalAmount >= threshold
|
||
return triggered, order.TotalAmount
|
||
}
|
||
|
||
// 触发条件 B:累计充值 ≥ 阈值
|
||
func CheckAccumulatedRecharge(card *IotCard, order *Order, threshold int64) (bool, int64) {
|
||
// 先累加当前订单金额
|
||
newAccumulated := card.AccumulatedRecharge + order.TotalAmount
|
||
triggered := newAccumulated >= threshold
|
||
return triggered, newAccumulated
|
||
}
|
||
```
|
||
|
||
#### 5.2 佣金金额计算
|
||
|
||
```go
|
||
// 检查并发放一次性佣金(单卡购买场景)
|
||
func TriggerOneTimeCommissionForCard(order *Order, card *IotCard) error {
|
||
// 1. 检查是否已发放

|
||
}
|
||
```
|
||
|
||
**关键说明**:
|
||
1. **触发条件**:基于单张卡/设备的充值金额(首充或累计充值)
|
||
2. **梯度判断**:基于该系列分配的销售业绩(从 ShopSeriesCommissionStats 查询)
|
||
3. **设备场景**:设备购买时只发放一次佣金,不按卡数倍增
|
||
4. **统计来源**:使用 `allocationID` 查询该系列分配的累计销量/销售额
|
||
|
||
#### 5.3 配置示例
|
||
|
||
**示例 1:固定一次性佣金(首充触发)**
|
||
```json
|
||
{
|
||
"enable_one_time_commission": true,
|
||
"one_time_commission_type": "fixed",
|
||
"one_time_commission_trigger": "single_recharge",
|
||
"one_time_commission_threshold": 10000, // 首充≥100元触发
|
||
"one_time_commission_mode": "fixed",
|
||
"one_time_commission_value": 2000 // 返20元
|
||
}
|
||
```
|
||
|
||
**业务效果**:
|
||
- 用户首次充值≥100元时,代理获得20元一次性佣金
|
||
- 该卡/设备后续再充值不再触发
|
||
|
||
---
|
||
|
||
**示例 2:梯度一次性佣金(基于销售金额 + 累计充值触发)**
|
||
```json
|
||
{
|
||
"enable_one_time_commission": true,
|
||
"one_time_commission_type": "tiered",
|
||
"one_time_commission_trigger": "accumulated_recharge",
|
||
"one_time_commission_threshold": 10000, // 累计充值≥100元才触发
|
||
"tiers": [
|
||
{
|
||
"tier_type": "sales_amount",
|
||
"threshold": 200000, // 系列累计销售额≥2000元
|
||
"mode": "fixed",
|
||
"value": 1000 // 返10元
|
||
},
|
||
{
|
||
"tier_type": "sales_amount",
|
||
"threshold": 400000, // 系列累计销售额≥4000元
|
||
"mode": "fixed",
|
||
"value": 1500 // 返15元
|
||
},
|
||
{
|
||
"tier_type": "sales_amount",
|
||
"threshold": 1000000, // 系列累计销售额≥10000元
|
||
"mode": "percent",
|
||
"value": 100 // 返10%(按充值金额)
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
**业务效果**:
|
||
- 当该系列分配的累计销售额≥4000元时
|
||
- 用户累计充值≥100元触发一次性佣金
|
||
- 代理获得15元(匹配到第二档梯度)
|
||
- 如果系列销售额后续达到10000元,新用户首充≥100元时,代理获得充值金额的10%

"tier_type": "sales_count",
|
||
"threshold": 40, // 系列累计销量≥40个
|

"mode": "percent",
|
||
"value": 200 // 返20%
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
**业务效果**:
|
||
- 当该系列分配的累计销量≥40个时
|
||
- 用户首充≥100元触发一次性佣金
|
||
- 代理获得15元(匹配到第二档梯度)
|
||
|

### 6. 钱包入账
|
||
|
||
**决策**:直接入账,无冻结期
|

```go
|
||
func CreditCommission(record *CommissionRecord) error {
|
||
return Transaction(func(tx *gorm.DB) error {
|
||
// 1. 获取店铺钱包
|
||
wallet := GetWallet("shop", record.ShopID)
|
||
|
||
// 2. 增加余额
|
||
wallet.Balance += record.Amount
|
||
UpdateWallet(wallet)
|
||
|
||
// 3. 记录余额
|
||
record.BalanceAfter = wallet.Balance
|
||
record.Status = 1 // 已入账
|
||
record.ReleasedAt = time.Now()
|
||
UpdateCommissionRecord(record)
|
||
|
||
// 4. 创建钱包交易记录

### 7. API 设计
|
||
|
||
```
|
||
# 佣金记录查询
|
||
GET /api/admin/commission-records 佣金记录列表
|
||
GET /api/admin/commission-records/:id 佣金记录详情
|
||
|
||
# 佣金统计
|
||
GET /api/admin/commission-stats 佣金统计(总收入、各来源占比)
|
||
GET /api/admin/commission-stats/daily 每日佣金统计
|
||
```
|
||
|
||
## Risks / Trade-offs
|
||
|
||
### 风险 1:异步计算失败
|
||
|
||
**风险**:佣金计算任务失败导致佣金未发放
|
||
|
||
**缓解**:
|
||
- Asynq 自动重试机制
|
||
- 记录任务执行日志
|
||
- 提供手动触发补偿接口
|
||
|
||
### 风险 2:并发更新钱包余额
|
||
|
||
**风险**:多笔佣金同时入账导致余额计算错误
|
||
|
||
**缓解**:
|
||
- 使用数据库事务
|
||
- 钱包更新使用乐观锁或悲观锁
|
||
|
||
### 风险 3:代理层级变更
|
||
|
||
**风险**:订单支付后代理层级变更,佣金计算基于哪个时间点?
|
||
|
||
**缓解**:
|
||
- 佣金计算基于订单支付时的代理关系
|
||
- 订单中可记录销售店铺ID快照
|
||
|
||
## Open Questions
|
||
|
||
1. **梯度一次性佣金的档位排序规则?**
|
||
- 当前设计:选择最高匹配档位(达标档位中阈值最高的)
|
||
- 待确认:是否正确?是否需要支持阶梯式累加?
|
||
|
||
2. **设备级购买如何处理?**
|
||
- 当前设计:设备购买时使用 Device.SeriesAllocationID 和 Device.FirstCommissionPaid
|
||
- 待确认:设备下多张卡时,一次性佣金只发一次(按设备),还是按卡数倍增?
|
||
|
||
3. **累计充值的统计周期?**
|
||
- 当前设计:永久累计(从卡开始使用至今)
|
||
- 待确认:是否需要支持按自然年/月重置累计金额?
|
||
|
||
4. **一次性佣金是否支持多级分佣?**
|
||
- 当前设计:只发放给卡/设备的直接归属店铺
|
||
- 待确认:是否需要上级代理也获得一次性佣金?如何分配比例?
