Esempio

Nel codice seguente viene illustrato come usare in modo imperativo .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 può essere usato anche in un file di configurazione, come illustrato nella configurazione seguente.

<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>

Commenti

La HttpTransportBindingElement classe è il punto di partenza per la creazione di un'associazione personalizzata che implementa il protocollo di trasporto HTTP. HTTP è il trasporto primario usato per scopi di interoperabilità. Questo trasporto è supportato da Windows Communication Foundation (WCF) per garantire l'interoperabilità con altri stack di servizi Web non WCF.

Il modello di servizio WCF usa questa classe per creare oggetti factory che implementano le IChannelFactory interfacce e IChannelListener . Questi oggetti factory, a loro volta, creano i canali e i listener che trasmettono messaggi SOAP usando il protocollo HTTP.

Per configurare le factory create da questa classe, impostare le relative proprietà, ad esempio AuthenticationScheme, HostNameComparisonModee MaxBufferSize.

È anche possibile impostare proprietà sulla classe base, TransportBindingElement, ad esempio ManualAddressing, MaxReceivedMessageSizee MaxBufferPoolSize. Per un elenco completo delle proprietà, vedere TransportBindingElement.
