go发送请求get|post

golang要请求远程网页,可以使用net/http包中的client提供的方法实现。查看了官方网站有一些示例,没有太全面的例子,于是自己整理了一下

get请求

get请求可以直接http.Get方法,非常简单

func httpGet() {
    resp, err := http.Get("http://www.01happy.com/demo/accept.php?id=1")
    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请求

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))
}

  

复杂的请求

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))
}
