golang 测试代码

package main

import (
  "net/http"
  "net/url"
  "fmt"
  "io/ioutil"
  "time"
  "net"
  "crypto/tls"
)

func TimeoutDialer(cTimeout time.Duration, rwTimeout time.Duration) func(net, addr string) (c net.Conn, err error) {
  return func(netw, addr string) (net.Conn, error) {
    conn, err := net.DialTimeout(netw, addr, cTimeout)
    if err != nil {
      return nil, err
    }
    conn.SetDeadline(time.Now().Add(rwTimeout))
    return conn, nil
  }
}

func main() {

  connectTimeout := 5 * time.Second
  readWriteTimeout := 100 * time.Millisecond

  c := http.Client{
    Transport: &http.Transport{
      TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
      Dial:      TimeoutDialer(connectTimeout, readWriteTimeout),
    },
  }

  uri := "https://www.youtobe.com"
  req, err := http.NewRequest(http.MethodPost, uri, nil)
  if err != nil {
    fmt.Println("req error:" + err.Error())
    return
  }

  req.Header = http.Header{}

  req.Header["Connection"] = []string{"Close"}
  req.Header["User-Agent"] = []string{"wpt-http-client/1.1"}

  data := make(url.Values)

  data["name"] = []string{"baixs"}
  data["hobby"] = []string{"runing"}

  resp, err := c.Do(req)
  if err != nil {
    fmt.Println("do error,err:" + err.Error())
    return
  }

  respBody, err := ioutil.ReadAll(resp.Body)

  fmt.Println(string(respBody))

}

测试结果

连接超时(包括握手)

传输超时(也就是读写,从accept开始计算 )
