無論使用何種綁定，WCF相對端點地址都在所有基址上公開

Question

我有這項自助服務。 在app.config中，我定義了兩個基地址。 一個用於http，一個用於net.tcp。

一個合同通過兩個端點公開，一個端點帶有basicHttpBinding，另一個端點帶有netTcpBinding。

現在，奇怪的是兩個端點在兩個基址上都可用。 如果我使用wcfclient.exe應用程序連接到任一端點，則兩個端點都將顯示。 即basicHttpBinding通過net.tcp和其他方法。

為什么會這樣，我能做些什么？

該配置供參考。

<configuration>
<system.serviceModel>
<services>
  <service name="FileServer.BookService" behaviorConfiguration="serviceMetadata">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost"/>
        <add baseAddress="net.tcp://localhost"/>
      </baseAddresses>
    </host>
    <endpoint address="BookService"
              binding="netTcpBinding"
              contract="FileServer.IBookService">
    </endpoint>
    <endpoint address="BookService/mex"
              binding="mexTcpBinding"
              contract="IMetadataExchange">
    </endpoint>
    <endpoint address="BookService"
      binding="basicHttpBinding"
      contract="FileServer.IBookService">
    </endpoint>
    <endpoint address="BookService/mex"
              binding="mexHttpBinding"
              contract="IMetadataExchange">
    </endpoint>
    <endpoint address="basic"
              binding ="basicHttpBinding"
              contract="FileServer.ITest">
    </endpoint>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="serviceMetadata">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="True"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
</system.serviceModel>

該WcfTestClient應用程序將從服務下載的元數據信息，而服務本身有三個端點 -所以用戶看到的是三個端點，而不是兩個服務。 即使您通過兩個不同的位置公開元數據，元數據也不是相對於端點或基址，而是相對於服務主機本身。

如果希望客戶端從HTTP地址獲取元數據僅獲取HTTP端點（對於TCP也是相同的），則可以使用兩個主機，如以下示例所示。

public class Post_09851985_ee54_4627_9af7_6a9505c2067f

    }
    [ServiceContract]
    public interface ITest
    {
      [OperationContract]
      Person Echo(Person person);
    }
    [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
    public class Service : ITest
    {
      public Person Echo(Person person)
      {
        return person;
      }
    }

      ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddressHttp), new Uri(baseAddressTcp));
      host.AddServiceEndpoint(typeof(ITest), new BasicHttpBinding(), "basic");
      host.AddServiceEndpoint(typeof(ITest), new NetTcpBinding(SecurityMode.None), "tcp");

      host.Description.Behaviors.Add(new ServiceMetadataBehavior());
      host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex");
      host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexTcpBinding(), "mex");

      host.Open();
      Console.WriteLine("Host opened");

      Console.WriteLine("Press ENTER to close");
      Console.ReadLine();

      host.Close();
    }
    public static void TwoHosts()
    {
      string baseAddressHttp = "http://" + Environment.MachineName + ":8000/Service";
      string baseAddressTcp = "net.tcp://" + Environment.MachineName + ":8008/Service";
      ServiceHost httpHost = new ServiceHost(typeof(Service), new Uri(baseAddressHttp));
      ServiceHost tcpHost = new ServiceHost(typeof(Service), new Uri(baseAddressTcp));
      httpHost.AddServiceEndpoint(typeof(ITest), new BasicHttpBinding(), "basic");
      tcpHost.AddServiceEndpoint(typeof(ITest), new NetTcpBinding(SecurityMode.None), "tcp");

      httpHost.Description.Behaviors.Add(new ServiceMetadataBehavior());
      tcpHost.Description.Behaviors.Add(new ServiceMetadataBehavior());
      httpHost.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex");
      tcpHost.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexTcpBinding(), "mex");

      httpHost.Open();
      tcpHost.Open();
      Console.WriteLine("Host opened");

      Console.WriteLine("Press ENTER to close");
      Console.ReadLine();

      httpHost.Close();
      tcpHost.Close();
    }
    public static void Test()
    {
      TwoHosts();
    }
  }
