go POST请求的时候设置http代理,代码直接贴出来

    req, _ := http.NewRequest("POST", "http://www.baidu.com",
			strings.NewReader(fmt.Sprintf("username=admin&password=%s", "123123")))
    //HTTP代理
	proxy := "http://127.0.0.1:1080/"
	proxyAddress, _ := url.Parse(proxy)
	client := &http.Client{
		Transport: &http.Transport{
			Proxy: http.ProxyURL(proxyAddress),
		},
	}
	resp, err := client.Do(req)
    body, _ := ioutil.ReadAll(resp.Body)
    defer resp.Body.Close()
    fmt.Println(string(body))

直接使用就可以
