proxy

Proxy中间件，可以将指定的请求转发至另外的服务，并可重写url。

Example

package main
import (
    "net/url"
    "github.com/vicanso/elton"
    "github.com/vicanso/elton/middleware"
)
func main() {
    e := elton.New()
    target, _ := url.Parse("https://www.baidu.com")
    e.GET("/*", middleware.NewProxy(middleware.ProxyConfig{
        // proxy done will call this function
        Done: func(c *elton.Context) {
        },
        // http request url rewrite
        Rewrites: []string{
            "/api/*:/$1",
        },
        Target: target,
        // change the request host
        Host: "www.baidu.com",
    }))
    err := e.ListenAndServe(":3000")
    if err != nil {
        panic(err)
    }
}
