解压缩

当 Content-Encoding header 设置为 gzip 时，Decompress 中间件会解压 HTTP 请求体。

所有核心中间件都位于 middleware 包中：

import "github.com/labstack/echo/v5/middleware"

用法

e.Use(middleware.Decompress())

自定义配置

e := echo.New()
e.Use(middleware.DecompressWithConfig(middleware.DecompressConfig{
  Skipper: middleware.DefaultSkipper,
}))

配置

包源码中的字段
字段	类型	说明	源码
`Skipper`	`Skipper`	Skipper defines a function to skip middleware.	L19
`GzipDecompressPool`	`Decompressor`	GzipDecompressPool defines an interface to provide the sync.Pool used to create/store Gzip readers	L22
`MaxDecompressedSize`	`int64`	MaxDecompressedSize limits the maximum size of decompressed request body in bytes. If the decompressed body exceeds this limit, the middleware returns HTTP 413 error. This prevents zip bomb attacks where small compressed payloads decompress to huge sizes. Default: 100 * MB (104,857,600 bytes) Set to -1 to disable limits (not recommended in production).	L29

包源码中的函数
类型	源码
`func Decompress() echo.MiddlewareFunc`	L53
`func DecompressWithConfig(config DecompressConfig) echo.MiddlewareFunc`	L61

默认配置

// Effective defaults applied when fields are left unset.
DecompressConfig{
  Skipper:             DefaultSkipper,
  GzipDecompressPool:  &DefaultGzipDecompressPool{},
  MaxDecompressedSize: 100 * MB,
}
