golang http 连接超时和传输超时的例子

 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)) }
