将 JSON 发送到服务器 windows phone 8

Question

我正在尝试使用 Web 客户端类将 JSON 字符串发送到服务器，但未返回任何结果，我已尝试使用 Rest Client 插件以确保服务器正在返回某些内容，这是我的 postRequest 方法`

 public static void PostRequest(WebClient webclient,string data,string
 url,string header,string method)
             {
                 Uri uri = new Uri(url, UriKind.Absolute);
                 webclient.Headers[HttpRequestHeader.ContentType] = header;
                 webclient.UploadStringAsync(uri,method,data);  
           }

这里是我调用这个方法的地方

 string newUserJson="{"User_Name":"yosyos","First_Name":"gfhgas","Last_Name":"jagfshg"}";

              wc = new WebClient();
              wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wb_UploadStringCompleted);
             string url = "http://670b9ada.ngrok.com/laravelProjects/TestVisWall/public/users";
              helper.PostRequest( wc, newUserJson, url, "application/json", "POST");

不要使用WebClient，Microsoft 不鼓励使用它。 试试 RestSharp 库，在我看来是一个非常好的库。 Restsharp添加recerense，Nuget方法更快：https://www.nuget.org/packages/RestSharp

RestClient client = new RestClient("baseurl");    
var request = new RestRequest("/path/script.php", Method.POST);

request.AddParameter("application/json; charset=utf-8", "json string", ParameterType.RequestBody);
request.RequestFormat = DataFormat.Json;

client.ExecuteAsync(request, response =>
                                         {
                                             if (response.StatusCode == HttpStatusCode.OK)
                                             {
                                                //OK
                                             }
                                         });
    }
