IClientMessageInspector Interfaccia

Definizione

Definisce un oggetto di controllo messaggi che può essere aggiunto alla raccolta MessageInspectors per visualizzare o modificare i messaggi.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

Esempi

Nell'esempio di codice seguente viene visualizzata un'implementazione che scrive stringhe sulla console quando viene chiamata.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

Nell'esempio di codice seguente viene illustrato come utilizzare un System.ServiceModel.Description.IEndpointBehavior per inserire il controllo di messaggio del client nell'endpoint client.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

Nell'esempio di codice seguente viene infine mostrata la procedura per modificare il file di configurazione del client in modo da utilizzare il comportamento dell'endpoint tramite un determinato endpoint.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>

Commenti

Implementare l'interfaccia IClientMessageInspector e aggiungerla alla raccolta MessageInspectors per controllare o modificare i messaggi quando passano attraverso un oggetto client 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. Per informazioni dettagliate, vedere ClientRuntime.For details, see ClientRuntime.

Metodi

AfterReceiveReply(Message, Object)

Consente di controllare o modificare un messaggio dopo che è stato ricevuto un messaggio di risposta, ma prima che venga restituito all'applicazione client.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)

Consente di controllare o modificare un messaggio prima che venga inviato un messaggio di richiesta a un servizio.Enables inspection or modification of a message before a request message is sent to a service.
