jquery and RESTful wcf service

我在vs2012中对RESTful wcf服务进行了xcrated。我可以访问这个服务器的浏览器。我的接口文件是这样的：

namespace RestService
{
    [ServiceContract]
    public interface IRestServiceImpl
    {
        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Xml,
            BodyStyle=WebMessageBodyStyle.Wrapped,
            UriTemplate = "xml/{id}"
            )]
        string XMLData(string id);
        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "json/{id}"
            )]
        string JSONData(string id);
    }
}

我的配置文件是：

  <system.serviceModel>
    <services>
      <service name="RestService.RestServiceImpl" behaviorConfiguration="ServiceBehavior">
        <endpoint address="" binding="webHttpBinding" contract="RestService.IRestServiceImpl" behaviorConfiguration="web">
        </endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

当我用ctr+F5运行服务时，它会给我一个url localhost:50046/RestServiceImpl.svc

当我向网络浏览器写入代码时，我可以访问我的服务，并收到回复：

代码为//localhost:50046/RestServiceImpl.svc/json/123响应为{"JSONDataResult":"you requested product 123"}

现在我的问题是，我将从我的html代码访问该服务。我将向服务发送一个数据，并得到该服务的响应。我的简单jquery代码是：

$("input:#giris").click(function(){
    function GetCategoriesJson() {
        $.ajax(
        {
            type:"GET",
            url:"localhost:50046/RestServiceImpl.svc",
            data:"{123}",
            contentType: "application/json; charset=utf-8", 
            dataType: "json/{123}", 
            success: OnSuccessJson, 
            error: OnErrorJson
        });
        function OnSuccessJson(data, status) {
            alert("basarili")
        }
        function OnErrorJson(data, status) {
            alert("Exception");
        }
        }   
    });

我必须做什么，必须写什么到类型、url、数据、内容类型、数据类型等。请帮助我已经工作了几天
