wcf 消息拦截

说明：命名空间为：WcfServiceInterpector

1：新建继承自IDispatchMessageInspector的ServiceInterpector类

public class ServiceInterpector : IDispatchMessageInspector
    {

        #region IDispatchMessageInspector 成员

        public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext)
        {
            ICSS.Plover.Log.LogRecorder.WriteInfo(new LogMessage("请求服务地址:" + request.Headers.To.AbsoluteUri + " 调用方法地址:" + request.Headers.Action));
            return "success";
        }

        public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
        {

        }

        #endregion
    }

2：新建继承自BehaviorExtensionElement, IServiceBehavior的MyServiceBehavior类

public class MyServiceBehavior : BehaviorExtensionElement, IServiceBehavior
    {

        public override Type BehaviorType
        {
            get { return typeof(MyServiceBehavior); }
        }
        protected override object CreateBehavior()
        {
            return new MyServiceBehavior();
        }
        #region IServiceBehavior Members
        public void AddBindingParameters(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
        {
        }
        public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
        {
            foreach (ChannelDispatcher chDisp in serviceHostBase.ChannelDispatchers)
            {
                foreach (EndpointDispatcher epDisp in chDisp.Endpoints)
                {
                    epDisp.DispatchRuntime.MessageInspectors.Add(new ServiceInterpector());
                }
            }
        }
        public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
        {
        }
        #endregion

    }

3：配置文件中添加配置

(1)添加扩展

  <system.serviceModel>

<extensions>    

   <behaviorExtensions>

      <add name="Test" type="WcfServiceInterpector.MyServiceBehavior, WcfServiceInterpector, Version=1.0.0.0, Culture=neutral,              PublicKeyToken=null" />      

  </behaviorExtensions>  

 </extensions>

  </system.serviceModel>

说明：type="类完整名称, (程序集名称), Version=1.0.0.0, Culture=neutral,  PublicKeyToken=null" />

（2）使用扩展

<serviceBehaviors>    

   <behavior name="DefaultBehavior">        

 <serviceMetadata httpGetEnabled="true" httpGetUrl="" />      

   <serviceDebug includeExceptionDetailInFaults="true" />      

   <serviceThrottling maxConcurrentCalls="200" maxConcurrentInstances="200" maxConcurrentSessions="200" />                <dataContractSerializer maxItemsInObjectGraph="2147483647" />    

     <Test/>      <!--上文中扩展定义的名称-->  

   </behavior>      

 </serviceBehaviors>
