Question

我正在尝试在同一个WCF服务中使用SOAP和RESTful。除了一个问题之外，我已经将它除了。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，它会出现以下错误：

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)

如果我评论json终点，事情就可以了。

你可以帮我找出原因吗？

提前致谢。

我刚刚添加了更改了json行为的绑定配置。我正在为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>

并添加了绑定配置：

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

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

帮自己一个忙，并停止尝试创建一个同时执行SOAP和REST的服务。你最终会弄得一团糟。检查您的要求并选择最适合您需求的方法。

SOAP，JSON和POX在相同的restful wcf中
