GO之HTTP操作

GET

resp, err := http.Get("http://www.test.local")
if err != nil {
    // handle error
}

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

fmt.Println(string(body))

POST

  1. http.Post

     resp, err := http.Post("http://www.test.local", "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))

  2. http.PostForm

     resp, err := http.PostForm("http://www.test.local", 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))

自定义请求

client := &http.Client{}

req, err := http.NewRequest("POST", "http://www.test.local", strings.NewReader("name=cjb"))
if err != nil {
    // handle error
}


req.Header.Set("User-Agent", "myClient")
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))
