Send get and post request by golang

api.go

//发送get请求
func get(url string) string {
	response, err := http.Get(url)
	if err != nil {
		fmt.Printf("%s", err)
		os.Exit(1)
	} else {
		defer response.Body.Close()
		contents, err := ioutil.ReadAll(response.Body)
		if err != nil {
			fmt.Printf("%s", err)
			os.Exit(1)
		}
		return string(contents)
	}
	return ""
}

// 发送post请求
func post(url string, jsonData string) string {
	var jsonStr = []byte(jsonData)

	req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
	req.Header.Set("Content-Type", "application/json")

	client := &http.Client{}
	resp, err := client.Do(req)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	fmt.Println("response Status:", resp.Status)
	fmt.Println("response Headers:", resp.Header)
	body, _ := ioutil.ReadAll(resp.Body)
	return string(body)
}
