Question

我一直在IIS中托管的WCF服务收到404错误。该服务是双工服务。我可以在Web浏览器中访问.svc。但是，当客户端尝试登录时，它会因404 Not Found错误而超时。我的web.config片段如下所示：

<system.webServer>
        <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
  <system.web>
    <customErrors mode="Off"/>
    <trust level="Full"/>
  </system.web>
 <system.serviceModel>
  <behaviors>
   <serviceBehaviors>
    <behavior name="">
     <serviceMetadata httpGetEnabled="true" />
     <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
   <serviceHostingEnvironment multipleSiteBindingsEnabled="false" aspNetCompatibilityEnabled="false">
     <baseAddressPrefixFilters>
       <add prefix="http://seeinstacksproductions.com/"/>
     </baseAddressPrefixFilters>
   </serviceHostingEnvironment>
   <bindings>
     <wsDualHttpBinding>
       <binding name="dualHttp" receiveTimeout="00:30:00" maxReceivedMessageSize="1048576" sendTimeout="00:01:00">
         <readerQuotas maxStringContentLength="99999999" maxArrayLength="9999999" maxBytesPerRead="999999"/>
         <security mode="None"/>
       </binding>
     </wsDualHttpBinding>
   </bindings>
   <services>
     <service name="OLII.Apps.Services.Automation.AutomatorService.WCFAutomatorService">
       <host>
         <baseAddresses>
           <add baseAddress="http://seeinstacksproductions.com/"/>
         </baseAddresses>
       </host>
       <endpoint address="Automator.svc" bindingConfiguration="dualHttp" binding="wsDualHttpBinding" contract="OLII.Apps.Services.ProxyClients.AutomatorServiceProxyClient.IWCFAutomatorService"/>
     </service>
   </services>
 </system.serviceModel>

我提出了我的应用程序发出的请求，它看起来像这样：

Answer 1

在出现wcf双工通信问题时，您必须描述网络拓扑，您的客户端是否与您的服务器位于同一LAN中，或者他是否通过Internet访问服务器，在某些网络方案中，无法使用双工通信。
