带超时的http，get、post请求

//get请求 func HttpGetT(addr string, timeout int) (ret string, err error) { if timeout < 0 { timeout = 5 } client := &http.Client{ Transport: &http.Transport{ Dial: func(netw, addr string) (net.Conn, error) { conn, err := net.DialTimeout(netw, addr, time.Second*time.Duration(timeout)) //设置建立连接超时 if err != nil { return nil, err } conn.SetDeadline(time.Now().Add(time.Second * time.Duration(timeout))) //设置发送接受数据超时 return conn, nil }, }, } res, err := client.Get(addr) if err != nil { return } defer res.Body.Close() body, err := ioutil.ReadAll(res.Body) if err != nil { return } ret = string(body) return } //post请求 func HttpPostT(addr string, data url.Values, timeout int) (ret string, err error) { if timeout < 0 { timeout = 5 } client := &http.Client{ Transport: &http.Transport{ Dial: func(netw, addr string) (net.Conn, error) { conn, err := net.DialTimeout(netw, addr, time.Second*time.Duration(timeout)) //设置建立连接超时 if err != nil { return nil, err } conn.SetDeadline(time.Now().Add(time.Second * time.Duration(timeout))) //设置发送接受数据超时 return conn, nil }, }, } res, err := client.PostForm(addr, data) if err != nil { return } defer res.Body.Close() body, err := ioutil.ReadAll(res.Body) if err != nil { return } ret = string(body) return }
