無論使用何種綁定，WCF都會暴露在所有基地址上的WCF相對端點地址

Question

我有這種自我託管的服務。在app.config中我定義了兩個基地址。一個用於http，一個用於net.tcp。

一個合約通過兩個端點公開，一個是basicHttpBinding，另一個是netTcpBinding。

現在，奇怪的是，兩個端點都可以在兩個baseaddresses。如果我使用wcfclient.exe應用程序連接到任一端點，則兩個端點都顯示出來。即basicHttpBinding net.tcp和其他方式。

這是爲什麼，我能做些什麼嗎？

該參考配置。

<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應用程序會下載從服務和服務的元數據信息本身有三個端點 - 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地址，而是相對於服務主機本身。

如果您希望客戶端從HTTP地址獲取元數據以僅獲取HTTP端點（對TCP而言也是相同的），則可以使用兩個主機，如下例所示。
