Method Override (方法重写) 中间件

Method Override 中间件检查从请求中重写的方法，并使用它来代替原来的方法。

出于安全原因，只有 POST 方法可以被重写。

用法

  1. e.Pre(middleware.MethodOverride())

自定义配置

用法

  1. e := echo.New()
  2. e.Pre(middleware.MethodOverrideWithConfig(middleware.MethodOverrideConfig{
  3.   Getter: middleware.MethodFromForm("_method"),
  4. }))

配置

  1. MethodOverrideConfig struct {
  2.   // Skipper defines a function to skip middleware.
  3.   Skipper Skipper
  5.   // Getter is a function that gets overridden method from the request.
  6.   // Optional. Default values MethodFromHeader(echo.HeaderXHTTPMethodOverride).
  7.   Getter MethodOverrideGetter
  8. }

默认配置

  1. DefaultMethodOverrideConfig = MethodOverrideConfig{
  2.   Skipper: defaultSkipper,
  3.   Getter:  MethodFromHeader(echo.HeaderXHTTPMethodOverride),
  4. }
