C# MVC调用webapi-优快云博客

本文介绍了一个前后端交互的实例，包括前端使用按钮触发GET请求，通过JavaScript调用接口获取数据，以及后端处理请求并从外部API获取信息的过程。演示了如何在前端使用jQuery发起GET请求，并在后端使用C#进行数据处理。

前台按钮

    <button class="btn btn-primary" style="margin-left:20px" onclick="Get1();" );">测试GET接口1</button>
	<button class="btn btn-primary" style="margin-left:20px" onclick="Get2();" );">测试GET接口2</button>

js代码

 <script>
        function Get1() {
           
            $.get("/Teacher/Get",{ "id": "小黑" }, function (answer) { 
                console.log(answer); 
                console.log("1");
            });
        }

        function Get2() { 
            $.ajax({
                url: "/Teacher/Get",
                type: "get",
                data: { "id": "aaa" },
                success: function (data) {
                    console.log(data);
                    console.log("2"); 
                } 
            })
        }
        
    </script>

后台代码1

 public ActionResult Get(string id)
        {
            string url = "http://api.nnzhp.cn/api/user/stu_info?stu_name='" + id + "'";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "GET";
            request.ContentType = "text/html;charset=UTF-8";
            request.UserAgent = null;
            request.Timeout = 6000;

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));
            string retString = myStreamReader.ReadToEnd();
            myStreamReader.Close();
            myResponseStream.Close(); 

            if (retString != "")
            {
               return this.Content(retString);
            }
            else
            {
                return this.RedirectToAction("list");
            }

        }

后台代码2

      [HttpGet]
        public JsonResult GetImportDriverList( int pageIndex, string companyId = "")
        {

            string url = "http://116.255.145.168:8001/Api/GetDriverList?companyId=" + companyId + "&pageIndex=" + pageIndex + "";
            WebRequest wRequest = WebRequest.Create(url);
            wRequest.Method = "GET";
            wRequest.ContentType = "text/html;charset=UTF-8";
            WebResponse wResponse = wRequest.GetResponse();
            Stream stream = wResponse.GetResponseStream();
            StreamReader reader = new StreamReader(stream, System.Text.Encoding.UTF8);
            string str = reader.ReadToEnd();   //url返回的值 
            reader.Close();
            wResponse.Close();

            JObject jo = (JObject)JsonConvert.DeserializeObject(str); 

            return AjaxJsonResult.SuccessResult(new { data = jo }, true); 

        }
