System.ServiceModel.Primitives.dll

Assembly:

System.ServiceModel.dll

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.

public:
 void AfterReceiveReply(System::ServiceModel::Channels::Message ^ % reply, System::Object ^ correlationState);

public void AfterReceiveReply (ref System.ServiceModel.Channels.Message reply, object correlationState);

abstract member AfterReceiveReply : Message * obj -> unit

Public Sub AfterReceiveReply (ByRef reply As Message, correlationState As Object)

Parâmetros

reply

Message

A mensagem a ser transformada em tipos e devolvida para o aplicativo cliente.

correlationState

Object

Correlação de dados de estado.

Exemplos

O exemplo de código a seguir mostra uma implementação que grava cadeias de caracteres no console quando a implementação é chamada.

#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 inspetor de mensagens do cliente no ponto de extremidade do cliente.

#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.

  <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 AfterReceiveReply para inspecionar ou modificar uma mensagem de resposta depois que ela tiver sido recebida pelo objeto cliente do WCF, mas antes de ser desserializada em objetos que são retornados ao aplicativo cliente.

O correlationState objeto é retornado pelo usuário quando BeforeSendRequest é chamado para essa mensagem. A prática recomendada é tornar isso em um System.Guid para garantir que não haja dois objetos correlationState iguais.
