IClientMessage检查器在WCF中不工作

Question

我有一个类MessageInspector，它实现IClientMessageInspecter。

namespace WCFAuthentication
{
public class MessageInspector : IClientMessageInspector
{
public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
//throw new NotImplementedException();
Debug.WriteLine("IClientMessageInspector.AfterReceiveReply called.");
Debug.WriteLine("Message: {0}", reply.ToString());
}
public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel)
{
//throw new NotImplementedException();
Debug.WriteLine("IClientMessageInspector.BeforeSendRequest called.");
return null;
}
}
}

我已经在WCF的web.config中配置了这一点：

<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5"/>
</system.web>
<system.serviceModel>
<extensions>
<behaviorExtensions>
<add
name="MessageInspector"
type="WCFAuthentication.MessageInspector, MessageInspector, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"/>
</behaviorExtensions>
</extensions>

</service>
<service name ="WCFAuthentication.Authentication">
<endpoint address="" behaviorConfiguration="restfulBehavior" binding="webHttpBinding" contract="WCFAuthentication.IAuthentication"/>
</service>
</services>

<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--

-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>

在运行wcf(托管在IIS中)时，它无法在we配置中识别我的"MessageInspector"类。

"/WCFAuthentication"应用程序中的服务器错误。

配置错误

描述：处理服务此请求所需的配置文件时出错。请查看下面的具体错误详细信息，并适当修改您的配置文件。

Answer 1

您不能以这种方式直接添加MessageInspector，您需要实现IEndpointBehavior和BehaviorExtensionElement。

MSDN提供了一个详细的示例。
