golang http 连接超时和传输超时的例子

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 ）
