wcf - EndpointDispatcher 处的 WCF 和 ContractFilter 不匹配

Question

我得到了以下错误..有什么问题？

由于 EndpointDispatcher 的 ContractFilter 不匹配，接收方无法处理带有 Action '' 的消息。这可能是因为合约不匹配（发送方和接收方之间的操作不匹配）或发送方和接收方之间的绑定/安全不匹配。检查发送方和接收方是否具有相同的合同和相同的绑定（包括安全要求，例如消息、传输、无）。

1. WSModules.svc

   <%@ ServiceHost language="C#" Service="WS.Modules.ServiceContracts.WSModules"%>
   

2. WS模块

   namespace WS.Modules.ServiceContracts
   {
       [ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
       public class WSModules : IWSModules
       {  
           public string XmlData(string id)
           {
               return "You requested product" + id;
           }
       }
   }
   

3. IWS 模块

   namespace WS.Interfaces.ServiceContracts
   {
           [ServiceContract]
           public interface IWSModules
           {
                   [OperationContract]
                   [WebGet(UriTemplate = "XmlData?id={id}")]
                   string XmlData(string id);
           }
   }
   

4. 网页配置

   <system.serviceModel>   
   <behaviors>
   <serviceBehaviors>       
           <!-- ### WSModules -->
           <behavior name="WSModulesBehavior">
             <serviceMetadata httpGetEnabled="True" />
             <serviceDebug includeExceptionDetailInFaults="true" />
             <serviceThrottling maxConcurrentCalls="24" maxConcurrentSessions="24" />
           </behavior>
         </serviceBehaviors>
         <endpointBehaviors>
           <behavior name="web">
             <webHttp/>
           </behavior>
         </endpointBehaviors>      
       </behaviors>
   <services>   
         <!--  ### WSModules Service-->
         <service behaviorConfiguration="WSModulesBehavior" name="WS.Modules.ServiceContracts.WSModules">
           <endpoint address="" binding="webHttpBinding" contract="WS.Interfaces.ServiceContracts.IWSModules"/>       
                   <host>
                     <baseAddresses>
                       <add baseAddress="http://xxx.xxx.xxx/commonwebsol/wswsdl" />
                     </baseAddresses>
                   </host>
                 </service>
               </services>
               <serviceHostingEnvironment multipleSiteBindingsEnabled="True"/>
             </system.serviceModel>
   

5. 我打开浏览器并输入 http://xxx.xxx.xxx/commonwebsol/WSWSDL/WSModules.svc - 工作正常。我得到了“svcutil.exe http://xxx.xxx.xxx/commonwebsol/WSWSDL/WSModules.svc?wsdl 然后如果我点击” http://xxx.xxx.xxx/commonwebsol/WSWSDL/WSModules.svc? wsdl " 我得到了 xml

6. 但是，如果我在浏览器中输入 http://xxx.xxx.xxx/commonwebsol/WSWSDL/WSModules.svc?XmlData?id=123 我收到以下错误...

   <Text xml:lang="en-US">The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a         contract mismatch (mismatched Actions between sender and receiver) or a binding/security         mismatch between the sender and the receiver. Check that sender and         receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).</Text> 
   

Answer 1

更改您的端点属性，如下所示

endpoint address="" binding="webHttpBinding" behaviorConfiguration="web" contract="WS.Interfaces.ServiceContracts.IWSModules" 

这将正常工作。
