IClientMessageInspector Gränssnitt

Definition

Definierar ett meddelandekontrollobjekt som kan läggas till i MessageInspectors samlingen för att visa eller ändra meddelanden.

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

Exempel

Följande kodexempel visar en implementering som skriver strängar till konsolen när implementeringen anropas.

#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

I följande kodexempel visas hur du använder en System.ServiceModel.Description.IEndpointBehavior för att infoga klientmeddelandekontrollen i klientslutpunkten.

#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

Slutligen visar följande kodexempel hur du ändrar klientkonfigurationsfilen för att använda slutpunktsbeteendet med en viss slutpunkt.

  <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>

Kommentarer

IClientMessageInspector Implementera gränssnittet och lägg till det i MessageInspectors samlingen för att inspektera eller ändra meddelanden när de passerar genom ett WCF-klientobjekt. Mer information finns i ClientRuntime.

Metoder

Name Description
AfterReceiveReply(Message, Object)

Aktiverar inspektion eller ändring av ett meddelande när ett svarsmeddelande har tagits emot, men innan det skickas tillbaka till klientprogrammet.

BeforeSendRequest(Message, IClientChannel)

Aktiverar inspektion eller ändring av ett meddelande innan ett begärandemeddelande skickas till en tjänst.
