golang使用http client发起get和post请求示例

func httpGet() {
  resp, err :=  http.Get("http://www.01happy.com/demo/accept.php")
  if err != nil {
    // handle error
  }

  defer resp.Body.Close()
  body, err := ioutil.ReadAll(resp.Body)
  if err != nil {
    // handle error
  }

  fmt.Println(string(body))
}

func httpPost() {
  resp, err := http.Post("http://www.01happy.com/demo/accept.php",
    "application/x-www-form-urlencoded",
    strings.NewReader("name=cjb"))
  if err != nil {
    fmt.Println(err)
  }

  defer resp.Body.Close()
  body, err := ioutil.ReadAll(resp.Body)
  if err != nil {
    // handle error
  }

  fmt.Println(string(body))
}

func httpPostForm() {
  resp, err := http.PostForm("http://www.01happy.com/demo/accept.php",
    url.Values{"key": {"Value"}, "id": {"123"}})

  if err != nil {
    // handle error
  }

  defer resp.Body.Close()
  body, err := ioutil.ReadAll(resp.Body)
  if err != nil {
    // handle error
  }

  fmt.Println(string(body))

}

func httpDo() {
  client := &http.Client{}

  req, err := http.NewRequest("POST", "http://www.01happy.com/demo/accept.php", strings.NewReader("name=cjb"))
  if err != nil {
    // handle error
  }

  req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
  req.Header.Set("Cookie", "name=anny")

  resp, err := client.Do(req)

  defer resp.Body.Close()

  body, err := ioutil.ReadAll(resp.Body)
  if err != nil {
    // handle error
  }

  fmt.Println(string(body))
}
