EndpointDispatcher 处的 WCF 和 ContractFilter 不匹配答案

【问题标题】：WCF and ContractFilter mismatch at the EndpointDispatcherEndpointDispatcher 处的 WCF 和 ContractFilter 不匹配

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）。

WSModules.svc

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

WSModules

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

IWSModules

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

Web.config

<behaviors>
<serviceBehaviors>       
        <!-- ### WSModules -->
        <behavior name="WSModulesBehavior">

        <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>

            </services>
            <serviceHostingEnvironment multipleSiteBindingsEnabled="True"/>
          </system.serviceModel>

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

但是，如果我在探索浏览器中输入 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>

【解决方案1】：

如下更改您的端点属性

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

这会很好。
