Key Auth 中间件

Key Auth 中间件提供了一个基于 key 的验证方式。

  • 对于有效的 key,它将调用下一个处理程序。
  • 对于无效的 key,它发送”401 - Unauthorized”的响应。
  • 对于空的 key,它发送”400 - Bad Request”。

使用

e.Use(middleware.KeyAuth(func(key string) bool{
 return key =="valid-key"
 }))

自定义配置

使用

e := echo.New()
e.Use(middleware.KeyAuthWithConfig(middleware.KeyAuthConfig{
  KeyLookup:"query:api-key",
  }))

配置

// KeyAuthConfig defines the config for KeyAuth middleware.

KeyAuthConfig struct
{
  // Skipper defines a function to skip middleware.
  Skipper Skipper  
  // KeyLookup is a string in the form of "<source>:<name>" that is used
  // to extract key from the request.
  // Optional. Default value "header:Authorization".
  // Possible values:
  // - "header:<name>"
  // - "query:<name>"
  KeyLookup string `json:"key_lookup"`
  // AuthScheme to be used in the Authorization header.
  // Optional. Default value "Bearer".
  AuthScheme string
  // Validator is a function to validate key.
  // Required.
  Validator KeyAuthValidator
}

默认配置

DefaultKeyAuthConfig = KeyAuthConfig{
  Skipper:defaultSkipper,
  KeyLookup:"header:"+ echo.HeaderAuthorization,
  AuthScheme:"Bearer",
}
