Exemplos

O código a seguir mostra como usar imperativamente o HttpTransportBindingElement.

Uri baseAddress = new Uri("http://localhost:8000/servicemodelsamples/service");

// Create a ServiceHost for the CalculatorService type and provide the base address.
using (ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress))
{
    // Create a custom binding that contains two binding elements.
    ReliableSessionBindingElement reliableSession = new ReliableSessionBindingElement();
    reliableSession.Ordered = true;

    HttpTransportBindingElement httpTransport = new HttpTransportBindingElement();
    httpTransport.AuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous;
    httpTransport.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;

    CustomBinding binding = new CustomBinding(reliableSession, httpTransport);

    // Add an endpoint using that binding.
    serviceHost.AddServiceEndpoint(typeof(ICalculator), binding, "");

    // Add a MEX endpoint.
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.HttpGetUrl = new Uri("http://localhost:8001/servicemodelsamples");
    serviceHost.Description.Behaviors.Add(smb);

    // Open the ServiceHostBase to create listeners and start listening for messages.
    serviceHost.Open();

    // The service can now be accessed.
    Console.WriteLine("The service is ready.");
    Console.WriteLine("Press <ENTER> to terminate service.");
    Console.WriteLine();
    Console.ReadLine();

    // Close the ServiceHostBase to shutdown the service.
    serviceHost.Close();
}

Dim baseAddress As New Uri("http://localhost:8000/servicemodelsamples/service")

' Create a ServiceHost for the CalculatorService type and provide the base address.
Using serviceHost As New ServiceHost(GetType(CalculatorService), baseAddress)
    ' Create a custom binding that contains two binding elements.
    Dim reliableSession As New ReliableSessionBindingElement()
    reliableSession.Ordered = True

    Dim httpTransport As New HttpTransportBindingElement()
    httpTransport.AuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous
    httpTransport.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard

    Dim binding As New CustomBinding(reliableSession, httpTransport)

    ' Add an endpoint using that binding.
    serviceHost.AddServiceEndpoint(GetType(ICalculator), binding, "")

    ' Add a MEX endpoint.
    Dim smb As New ServiceMetadataBehavior()
    smb.HttpGetEnabled = True
    smb.HttpGetUrl = New Uri("http://localhost:8001/servicemodelsamples")
    serviceHost.Description.Behaviors.Add(smb)

    ' Open the ServiceHostBase to create listeners and start listening for messages.
    serviceHost.Open()

    ' The service can now be accessed.
    Console.WriteLine("The service is ready.")
    Console.WriteLine("Press <ENTER> to terminate service.")
    Console.WriteLine()
    Console.ReadLine()

    ' Close the ServiceHostBase to shutdown the service.
    serviceHost.Close()
End Using

HttpTransportBindingElement também pode ser usado em um arquivo de configuração, conforme mostrado na configuração a seguir.

<bindings>  
  <customBinding>  
    <binding name="Binding1">  
      <reliableSession acknowledgementInterval="00:00:00.2000000" enableFlowControl="true"  
                        maxTransferWindowSize="32" inactivityTimeout="00:10:00" maxPendingChannels="128"  
                        maxRetryCount="8" ordered="true" />  
      <security mode="None"/>  
      <httpTransport authenticationScheme="Anonymous" bypassProxyOnLocal="false"  
                    hostNameComparisonMode="StrongWildcard"   
                    proxyAuthenticationScheme="Anonymous" realm=""   
                    useDefaultWebProxy="true" />  
    </binding>  
  </customBinding>  
</bindings>  

Comentários

A HttpTransportBindingElement classe é o ponto de partida para criar uma associação personalizada que implementa o protocolo de transporte HTTP. HTTP é o transporte primário usado para fins de interoperabilidade. Esse transporte tem suporte do WCF (Windows Communication Foundation) para garantir a interoperabilidade com outras pilhas de serviços Web não WCF.

O modelo de serviço WCF usa essa classe para criar objetos de fábrica que implementam as IChannelFactory interfaces e IChannelListener . Esses objetos de fábrica, por sua vez, criam os canais e ouvintes que transmitem mensagens SOAP usando o protocolo HTTP.

Você configura as fábricas que essa classe cria definindo suas propriedades, como AuthenticationScheme, HostNameComparisonModee MaxBufferSize.

Você também pode definir propriedades na classe base, TransportBindingElement, como ManualAddressing, MaxReceivedMessageSizee MaxBufferPoolSize. Para obter uma lista completa de propriedades, consulte TransportBindingElement.
