GO http库使用示例

1.  自定义的http请求封装

func SendRequest(method string, url string, requestBody string, headers map[string]string) ([]byte, error) {
	client := &http.Client{}
	request, err := http.NewRequest(method, url, strings.NewReader(requestBody))
	if err != nil {
		log.Println(err)
	}
	for k, v := range headers {
		request.Header.Add(k, v)
	}
	resp, err := client.Do(request)
	if err != nil {
		log.Println(err)
	}
	defer resp.Body.Close()
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		log.Printf("读取content失败 error: %+v", err)
		return []byte{}, err
	}
	log.Println(string(body))
	return body, err
}
