IClientMessageInspector Interface

Definição

Define um objeto do inspetor de mensagem que pode ser adicionado à coleção MessageInspectors para exibir ou modificar as mensagens.Defines a message inspector object that can be added to the MessageInspectors collection to view or modify messages.

public interface class IClientMessageInspector
public interface IClientMessageInspector
type IClientMessageInspector = interface
Public Interface IClientMessageInspector

Exemplos

O exemplo de código a seguir mostra uma implementação que grava cadeias de caracteres no console quando a implementação é chamada.The following code example shows an implementation that writes strings to the console when the implementation is called.

#region IClientMessageInspector Members
public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
  Console.WriteLine("IClientMessageInspector.AfterReceiveReply called.");
  Console.WriteLine("Message: {0}", reply.ToString());
}

public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, IClientChannel channel)
{
  Console.WriteLine("IClientMessageInspector.BeforeSendRequest called.");
  return null;
}
#Region "IClientMessageInspector Members"
    Public Sub AfterReceiveReply(ByRef reply As System.ServiceModel.Channels.Message, _
                       ByVal correlationState As Object) Implements IClientMessageInspector.AfterReceiveReply
        Console.WriteLine("IClientMessageInspector.AfterReceiveReply called.")
        Console.WriteLine("Message: {0}", reply.ToString())
    End Sub

    Public Function BeforeSendRequest(ByRef request As System.ServiceModel.Channels.Message, _
            ByVal channel As IClientChannel) As Object Implements IClientMessageInspector.BeforeSendRequest
        Console.WriteLine("IClientMessageInspector.BeforeSendRequest called.")
        Return Nothing
    End Function

O exemplo de código a seguir mostra como usar um System.ServiceModel.Description.IEndpointBehavior para inserir o Inspetor de mensagem do cliente no ponto de extremidade do cliente.The following code example shows how to use an System.ServiceModel.Description.IEndpointBehavior to insert the client message inspector in the client endpoint.

#region IEndpointBehavior Members
public void AddBindingParameters(
  ServiceEndpoint endpoint, BindingParameterCollection bindingParameters
) { return; }

public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
  clientRuntime.MessageInspectors.Add(new Inspector());
  foreach (ClientOperation op in clientRuntime.Operations)
    op.ParameterInspectors.Add(new Inspector());
}

public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
  endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new Inspector());
  foreach (DispatchOperation op in endpointDispatcher.DispatchRuntime.Operations)
    op.ParameterInspectors.Add(new Inspector());
}

public void Validate(ServiceEndpoint endpoint){ return; }
#Region "IEndpointBehavior Members"
    Public Sub AddBindingParameters(ByVal endpoint As ServiceEndpoint, ByVal bindingParameters _
                                    As BindingParameterCollection) Implements IEndpointBehavior.AddBindingParameters
        Return
    End Sub

    Public Sub ApplyClientBehavior(ByVal endpoint As ServiceEndpoint, ByVal clientRuntime As ClientRuntime) _
    Implements IEndpointBehavior.ApplyClientBehavior
        clientRuntime.MessageInspectors.Add(New Inspector())
        For Each op As ClientOperation In clientRuntime.Operations
            op.ParameterInspectors.Add(New Inspector())
        Next op
    End Sub

    Public Sub ApplyDispatchBehavior(ByVal endpoint As ServiceEndpoint, ByVal endpointDispatcher As  _
                                     EndpointDispatcher) Implements IEndpointBehavior.ApplyDispatchBehavior
        endpointDispatcher.DispatchRuntime.MessageInspectors.Add(New Inspector())
        For Each op As DispatchOperation In endpointDispatcher.DispatchRuntime.Operations
            op.ParameterInspectors.Add(New Inspector())
        Next op
    End Sub

Public Sub Validate(ByVal endpoint As ServiceEndpoint) Implements IEndpointBehavior.Validate
    Return
End Sub

Por fim, o exemplo de código a seguir mostra como modificar o arquivo de configuração do cliente para usar o comportamento do ponto de extremidade com um ponto de extremidade específico.Finally, the following code example shows how to modify the client configuration file to use the endpoint behavior with a particular endpoint.

  <client>
      <endpoint 
        address="http://localhost:8080/SampleService" 
        behaviorConfiguration="clientInspectorsAdded" 
        binding="wsHttpBinding"
        bindingConfiguration="WSHttpBinding_ISampleService" 
        contract="ISampleService"
        name="WSHttpBinding_ISampleService"
      >
      </endpoint>
  </client>
<behaviors>
  <endpointBehaviors>
    <behavior name="clientInspectorsAdded">
      <clientInterceptors />
    </behavior>
  </endpointBehaviors>
</behaviors>
<extensions>
  <behaviorExtensions>
    <add 
      name="clientInterceptors" 
      type="Microsoft.WCF.Documentation.InspectorInserter, HostApplication, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"
  />
  </behaviorExtensions>
</extensions>

Comentários

Implemente a interface IClientMessageInspector e adicione-a à coleção MessageInspectors para inspecionar ou modificar mensagens à medida que elas passam por um objeto cliente WCF.Implement the IClientMessageInspector interface and add it to the MessageInspectors collection to inspect or modify messages as they pass through a WCF client object. Para obter detalhes, consulte ClientRuntime.For details, see ClientRuntime.

Métodos

AfterReceiveReply(Message, Object)

Permite a inspeção ou modificação de uma mensagem depois que uma mensagem de resposta é recebida, mas antes de passá-la de volta para o aplicativo cliente.Enables inspection or modification of a message after a reply message is received but prior to passing it back to the client application.

BeforeSendRequest(Message, IClientChannel)

Permite a inspeção ou modificação de uma mensagem antes de uma mensagem de solicitação ser enviada a um serviço.Enables inspection or modification of a message before a request message is sent to a service.
