Go语言实现Get接口请求实例

2020年04月21日

Md5生成

func md5V3(str string) string {
	w := md5.New()
	io.WriteString(w, str)
	md5str := fmt.Sprintf("%x", w.Sum(nil))
	return strings.ToUpper(md5str)
}

GetUrl

//GET方式提交请求至服务端
func GetUrl() {

	// 请求参数
	appkey := "7819fc**709142eeb32e10bc44ce19f3"
	seckey := "F39AC**D7A83C5E606F94291DF46554B"
	//encode := "utf-8"
	// Http请求头设置
	timespan := strconv.FormatInt(time.Now().Unix(),10)
	token := appkey + timespan + seckey
	log.Println(token)
	cipherStr :=md5V3(token)
	log.Println("MD5加密后为 ：", cipherStr)

	// 设置请求Url-请自行设置Url
	reqInterNme := "http://api.qichacha.com/ECIV4/Search"
	paramStr := "keyword=阿里巴巴"
	urlString := reqInterNme + "?key=" + appkey + "&" + paramStr
	log.Println("url="+urlString)
	// nil 位置参数是Header 
	// 其设置值在下面的两句
	// req.Header.Set("Token", cipherStr)
	// req.Header.Set("Timespan", timespan)
	req, err := http.NewRequest("GET",urlString, nil)
	req.Header.Set("Token", cipherStr)
	req.Header.Set("Timespan", timespan)

	client := &http.Client{}
	resp, err := client.Do(req)

	log.Println(err)

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

	if err != nil {
		// handle error
	}
	log.Println("Result:")
	fmt.Println(string(body))
}

这是一个调取开发平台接口的代码实例，相关对Java语言实现，代码量少了许多。

其运行结果：

只是个人做的一个笔记。其他阅读者有可能看不太明白。呵呵！
