Voorbeelden

De volgende code laat zien hoe u de 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 kan ook worden gebruikt in een configuratiebestand, zoals wordt weergegeven in de volgende configuratie.

<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>

Opmerkingen

De HttpTransportBindingElement klasse is het startpunt voor het maken van een aangepaste binding waarmee het HTTP-transportprotocol wordt geïmplementeerd. HTTP is het primaire transport dat wordt gebruikt voor interoperabiliteitsdoeleinden. Dit transport wordt ondersteund door Windows Communication Foundation (WCF) om interoperabiliteit met andere niet-WCF-webservicesstacks te garanderen.

Het WCF-servicemodel gebruikt deze klasse om fabrieksobjecten te maken die de IChannelFactory en IChannelListener interfaces implementeren. Deze factoryobjecten maken op hun beurt de kanalen en listeners die SOAP-berichten verzenden met behulp van het HTTP-protocol.

U configureert de factory's die door deze klasse worden gemaakt door de eigenschappen in te stellen, zoals AuthenticationScheme, HostNameComparisonModeen MaxBufferSize.

U kunt ook eigenschappen instellen op de basisklasse, TransportBindingElementzoals ManualAddressing, MaxReceivedMessageSizeen MaxBufferPoolSize. Zie voor een volledige lijst met eigenschappen TransportBindingElement.
