用Go写了一个相似Proxy的小程序,能够用来訪问goolge个人使用还是能够的.

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	http.HandleFunc("/", route)
	e := http.ListenAndServe(":80", nil)
	if e != nil {
		fmt.Println(e)
	}
}

func route(w http.ResponseWriter, r *http.Request) {
	req, _ := http.NewRequest(r.Method, "", r.Body)
	req.URL = r.URL
	req.URL.Host = r.Host //"www.qq.com"
	req.URL.Scheme = "http"
	for _, v := range r.Cookies() {
		req.AddCookie(v)
	}
	//req.Header = r.Header 这里的Header就不要使用了,使用的话他会自己主动跳转到https,代理就出问题了.
	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		fmt.Println("Here:", err)
		return
	}
	for k, v := range resp.Header {
		for _, value := range v {
			w.Header().Add(k, value)
		}
	}
	for _, cookie := range resp.Cookies() {
		w.Header().Add("Set-Cookie", cookie.Raw)
	}
	w.WriteHeader(resp.StatusCode)
	io.Copy(w, resp.Body)
	resp.Body.Close()
	r.Body.Close()
}

这个用来訪问海外站点的话,要在本地host,把 域名绑定到IP,比如：1.1.1.1 www.google.com
