WCF-消息拦截 也可异常拦截
?
说明：命名空间为：WcfServiceInterpector
1：新建继承自IDispatchMessageInspector的ServiceInterpector类
?
1 public class ServiceInterpector : IDispatchMessageInspector 2 { 3 4 #region IDispatchMessageInspector 成员 5 6 public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext) 7 { 8 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)); 9 return "success";10 }11 12 public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState)13 {14 15 }16 17 #endregion18 }?
2：新建继承自BehaviorExtensionElement, IServiceBehavior的MyServiceBehavior类
1 public class MyServiceBehavior : BehaviorExtensionElement, IServiceBehavior 2 { 3 4 public override Type BehaviorType 5 { 6 get { return typeof(MyServiceBehavior); } 7 } 8 protected override object CreateBehavior() 9 {10 return new MyServiceBehavior();11 }12 #region IServiceBehavior Members13 public void AddBindingParameters(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)14 {15 }16 public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)17 {18 foreach (ChannelDispatcher chDisp in serviceHostBase.ChannelDispatchers)19 {20 foreach (EndpointDispatcher epDisp in chDisp.Endpoints)21 {22 epDisp.DispatchRuntime.MessageInspectors.Add(new ServiceInterpector());23 }24 }25 }26 public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)27 {28 }29 #endregion30 31 }?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>?
