wcf - SOAP、JSON 和 POX 在同一个安静的 wcf 中

Question

我试图在同一个 WCF 服务中使用 SOAP 和 RESTful。除了一个问题，我也实现了这一点。以下是我的 web.config:

<service behaviorConfiguration="webBehaviour" name="MyServices">
        <clear />
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttp"
         name="basicHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="ws" binding="wsHttpBinding" bindingConfiguration="WsHttp"
          name="wsHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="web" binding="webHttpBinding" bindingConfiguration="WebHttp" behaviorConfiguration="webBehavior"
          name="webHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="json" binding="webHttpBinding" bindingConfiguration="WebHttp" behaviorConfiguration="webJSONBehavior"
          name="webJSONHttpBinding" contract="DJSharedServices.ISharedServices" />
        <endpoint address="mex" binding="mexHttpBinding"    contract="IMetadataExchange"   name="mexBinding" />        
       </service>    
    </services>

当我拥有所有端点时，它会给出以下错误:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.NullReferenceException: Object reference not set to an instance of an object.

   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage1(MessageRpc& rpc)
   at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)

如果我注释掉 json 端点，一切正常。

你能帮我找出原因吗？？

提前致谢。

好吧，我刚刚添加了更改 json 行为的绑定(bind)配置。我对 JSON 和 POX 使用相同的 binging 配置。现在我已将配置更改为:

<service behaviorConfiguration="WebBehaviour" name="MyServices">
        <clear />
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttp"
         name="basicHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="ws" binding="wsHttpBinding" bindingConfiguration="WsHttp"
          name="wsHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="web" binding="webHttpBinding" bindingConfiguration="WebHttp" behaviorConfiguration="webBehavior"
          name="webHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="json" binding="webHttpBinding" bindingConfiguration="WebjsonHttp" behaviorConfiguration="webJSONBehavior"
          name="webJSONHttpBinding" contract="DJSharedServices.IMyServices" />
        <endpoint address="mex" binding="mexHttpBinding"    contract="IMetadataExchange"   name="mexBinding" />        
       </service> 

并添加了绑定(bind)配置:

 <webHttpBinding>
        <binding name="WebHttp"  >
          <security mode="None"></security>
        </binding>

        <binding name="WebjsonHttp"  >
          <security mode="None"></security>
        </binding>
      </webHttpBinding>
