WCF中REST使用POST方式

[OperationContract]
       [WebInvoke(Method = "POST",ResponseFormat = WebMessageFormat.Json,RequestFormat = WebMessageFormat.Json,UriTemplate = "data")]
       string PostData(User u);

 

public string PostData(User u)
      {

         return "Received: " + u.name+" " +u.title;
      }

客户端：

private void button3_Click(object sender, EventArgs e)
      {
          string json = null;
          WebClient client = new WebClient();
          client.Headers["Content-Type"] = "application/json";

          DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(User));
          using (MemoryStream stream = new MemoryStream())
          {
              serializer.WriteObject(stream, new User { name="suzhi",age=12,title="uu"});
              stream.Flush();
              json = Encoding.UTF8.GetString(stream.ToArray(), 0, (int)stream.Length);

          }
          client.UploadStringCompleted += new UploadStringCompletedEventHandler(client_UploadStringCompleted);
          client.UploadStringAsync(new Uri("http://192.168.15.236:7117/data"), "POST", json);
      }
      void client_UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
      {
          if (e.Error == null)
          {
              MessageBox.Show("OK");
          }
          else
          {
              MessageBox.Show(e.Error.Message);
          }

      }
