```yaml
middleware:
enable_auth: true
enable_rate_limiter: true # Changed to true
enable_rate_limiter: true # 设置为 true 启用限流
rate_limiter:
max: 5 # Low limit for testing
expiration: "1m" # 1 minute window
storage: "memory"
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）
```
### 2. Restart Server
**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)
```

}
```
### 4. Wait for Window to Reset
### 4. Test Per-IP Rate Limiting
Wait 1 minute, then try again:
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
```
### 5. Disable Rate Limiter
### 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 # Back to false
enable_rate_limiter: false # 设置为 false 禁用限流
```
Server will reload config automatically (no restart needed).
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
```
