无论使用何种绑定，WCF都会暴露在所有基地址上的WCF相对端点地址

Question

我有这种自我托管的服务。在app.config中我定义了两个基地址。一个用于http，一个用于net.tcp。

一个合约通过两个端点公开，一个是basicHttpBinding，另一个是netTcpBinding。

现在，奇怪的是，两个端点都可以在两个baseaddresses。如果我使用wcfclient.exe应用程序连接到任一端点，则两个端点都显示出来。即basicHttpBinding net.tcp和其他方式。

这是为什么，我能做些什么吗？

该参考配置。

<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>

的WcfTestClient应用程序会下载从服务和服务的元数据信息本身有三个端点 - 所以用户看到的是三个端点，而不是两个服务。即使您通过两个不同的位置公开元数据，元数据也不是相对于端点或基地址，而是相对于服务主机本身。

如果您希望客户端从HTTP地址获取元数据以仅获取HTTP端点（对TCP而言也是相同的），则可以使用两个主机，如下例所示。
