发起自定义 http 请求

http-client-do.go

func reqPost(url string, body io.Reader) ([]byte, error) {
	req, err := http.NewRequest("POST", url, body)
	if err != nil {
		return nil, err
	}

	req.Header.Set("User-Agent", "go-dnspod (shallwedance@126.com)")
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		return nil, err
	}
	defer resp.Body.Close()

	respBody, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		return nil, err
	}
	return respBody, nil
}

req.Header.Set("Content-Type", "application/x-www-form-urlencoded") 如果不设置 content-type ， 则无法传递 body 信息
