如何将参数传递给WCF post方法(restful服务)

我正在开发一个基于WCF rest的服务。我已经在我的服务中编写了Get和Post方法，当我输入URL（JSON格式.）时，Get方法能够工作（获取数据）

问题是，当我尝试对POST方法进行同样的操作时，url导航到其他页面"找不到页面…"。

我知道POST方法需要提交表单来处理请求。

因此，我尝试了chrome扩展（Simple Rest客户端、Advanced Rest客户端和Post man Rest客户端）和Fiddler。

在这里，我发布了我的服务方法-Get方法（接口方法声明）。

[OperationContract]
[WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, 
ResponseFormat =   WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, 
UriTemplate = "GetCategoryTypes/")]
List<CategoryType> GetCategoryTypes();

这是我的POST方法

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "AddOrders/", 
RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest)]
int AddOrders(decimal amount, int tableID, DateTime orderDate, int isActive);

这是我的服务web.config文件。

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
   </system.web>

    <services>
      <service name="EMC.DD.ServiceLayer.Service1" ehaviorConfiguration="ServiceBehaviour">
        <endpoint address="http://localhost/EMCService/Service1.svc" 
           binding="basicHttpBinding" contract="EMC.DD.ServiceLayer.IService1">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>      
      </service>
      <service name="EMC.DD.ServiceLayer.Service2" 
         behaviorConfiguration="ServiceBehaviour1">

            <dns value="localhost" />
          </identity>
        </endpoint>     
      </service>
    </services>

      <serviceBehaviors>

        </behavior>
        <behavior name ="ServiceBehaviour1">       
          <serviceMetadata httpGetEnabled="true" />        
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name ="web">

    </behaviors> 
  </system.serviceModel>
 <system.webServer>
        <directoryBrowse enabled="true" />
  </system.webServer>
</configuration>

我真的不确定我的方法构造（POST方法）或我需要测试它的方式是否有任何错误

我需要你们所有专家的帮助，在过去的两天里，我一直在与这个问题作斗争，至少我是来这里发布它的。

非常感谢您的帮助。

  [OperationContract]
  [WebInvoke(Method = "POST", UriTemplate = "AddOrders", RequestFormat =   
  WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,BodyStyle = 
  MessageBodyStyle.Bare)]
  int AddOrders(RequestData orderRequestData);

        WebClient WC = new WebClient();
        WC.Headers.Add("Content-Type", "application/json");
        WC.Encoding = Encoding.UTF8;
        MemoryStream MS = new MemoryStream();
        DataContractJsonSerializer JSrz = new 
        DataContractJsonSerializer(typeof(RequestData));
        JSrz.WriteObject(MS, order);
        string data = Encoding.UTF8.GetString(MS.ToArray(), 0, (int)MS.Length);
        byte[] res1 = 
        WC.UploadData("http://localhost/EMCService/Service2.svc/AddOrders", "POST",MS.ToArray());
        MS = new MemoryStream(res1);
        JSrz = new DataContractJsonSerializer(typeof(int));
        int result = (int)JSrz.ReadObject(MS);
