| `compression_test.go` | 压缩测试 |
## For AI Agents
### Working In This Directory
- 支持 Gzip 和 Deflate 压缩
- 自动检测 Accept-Encoding 头选择压缩方式
- 压缩级别可配置1-9默认 6
- 小于 1KB 的响应不压缩
### Testing Requirements
- 运行测试:`go test ./internal/middleware/compression/...`
- 测试压缩检测、响应处理、级别配置
### Common Patterns
- 使用 fasthttp 的内置压缩支持
- Content-Type 过滤:仅压缩 text/* 和 application/json
- Vary: Accept-Encoding 头自动添加
## Dependencies
### Internal
- `../` - 中间件接口定义
- `../../config/` - 压缩配置
### External
- `github.com/valyala/fasthttp` - HTTP 框架(内置压缩)
