Rewrite (重写) 中间件

Rewrite 中间件会根据提供的规则重写URL路径，它更适用于向后兼容与创建更清晰、更具描述性的链接。

用法

  1. e.Pre(middleware.Rewrite(map[string]string{
  2.   "/old":              "/new",
  3.   "/api/*":            "/$1",
  4.   "/js/*":             "/public/javascripts/$1",
  5.   "/users/*/orders/*": "/user/$1/order/$2",
  6. }))

星号中捕获的值可以通过索引检索，例如 $1, $2 等等。

Custom Configuration

用法

  1. e := echo.New()
  2. e.Pre(middleware.RewriteWithConfig(middleware.RewriteConfig{}))

配置

  1. // RewriteConfig defines the config for Rewrite middleware.
  2. RewriteConfig struct {
  3.   // Skipper defines a function to skip middleware.
  4.   Skipper Skipper
  6.   // Rules defines the URL path rewrite rules.
  7.   Rules map[string]string `yaml:"rules"`
  8. }

默认配置

重写中间件应该在路由之前通过 Echo#Pre() 注册从而触发。
