WCF 发现找到端点，但地址是 localhost

Question

我有一个名为“GetNameService”的 wcf 可发现服务，它托管在 PC @ 10.0.0.5:8732 上。它由 wsHttpBinding 托管，可通过 UdpEndpoint 发现。我还有一个客户端 @ 10.0.0.9，它在同一网络中发现此类服务。当我运行客户端时，我能够发现该服务，但发现的服务的终点是其中包含 localhost。怎么会这样，请帮帮我。

更多信息，

使用了 App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

 <system.web>
  <compilation debug="true" />
 </system.web>
 <!-- When deploying the service library project, the content of the config file must be added to the host's
 app.config file. System.Configuration does not support config files for libraries. -->
 <system.serviceModel>
  <services>
   <service name="NameService.GetNameService">
    <host>
     <baseAddresses>
      <add baseAddress = "http://10.0.0.5:8732/Design_Time_Addresses/NameService/GetNameService/" />
     </baseAddresses>
    </host>
    <!-- Service Endpoints -->
    <!-- Unless fully qualified, address is relative to base address supplied above -->
    <endpoint address ="" binding="wsHttpBinding" contract="NameService.IGetNameService">
     <!--
       Upon deployment, the following identity element should be removed or replaced to reflect the
       identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
       automatically.
     -->
     <identity>
      <dns value="localhost"/>
     </identity>
    </endpoint>
    <!-- Metadata Endpoints -->
    <!-- The Metadata Exchange endpoint is used by the service to describe itself to clients. -->
    <!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
   </service>
  </services>
  <behaviors>
   <serviceBehaviors>
    <behavior>
     <!-- To avoid disclosing metadata information,
     set the value below to false and remove the metadata endpoint above before deployment -->
     <serviceMetadata httpGetEnabled="True"/>
     <!-- To receive exception details in faults for debugging purposes,
     set the value below to true. Set to false before deployment
     to avoid disclosing exception information -->
     <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
 </system.serviceModel>

</configuration>

我在客户端机器中打开浏览器并输入服务地址，我可以看到服务详细信息页面，但 wsdl 链接仍然指向 localhost（如下所示）

svcutil.exe http://localhost:8732/Design_Time_Addresses/NameService/GetNameService/?wsdl

而不是

svcutil.exe http://10.0.0.5:8732/Design_Time_Addresses/NameService/GetNameService/?wsdl

此外，同样的应用程序似乎在我的工作场所工作，那里有一个可用的 dns，系统通过一个交换机连接，因为它在我家里的电脑不工作通过路由器连接。这会影响什么吗？！？

更新 它不在 IIS 中运行，它是通过普通控制台应用程序托管的

Answer 1

如果您在 IIS 上运行，则必须为您的站点设置默认主机名规则：

1. 打开 IIS
2. 右键单击您的网站，然后单击“属性”
3. 单击“网站”选项卡，然后单击“网站标识”标题下的“高级”按钮
4. 您应该有网站的默认身份（TCP 端口 8732）。编辑它并确保主机头值是您网站的域名（所以它应该是 www.yourdomain.com）

Answer 2

通过使用在代码中解决它（用于 tcp.net 连接）。

// Add discovery feature.
m_Host.AddServiceEndpoint(new Discovery.UdpDiscoveryEndpoint());
m_Host.Description.Behaviors.Add(new Discovery.ServiceDiscoveryBehavior());
// Add ordinary service feature
var binding = new NetTcpBinding();
binding.Security.Message.ClientCredentialType = MessageCredentialType.None;
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.None;
m_Host.AddServiceEndpoint(
        typeof(IMyServiceContract),
        new NetTcpBinding(SecurityMode.None),
        new UriBuilder { Scheme = Uri.UriSchemeNetTcp, Port = 8732, Host = "10.0.0.5" , Path = "MyServiceContractPath" }.Uri
        );

剩下的唯一（也许更小）问题是将哪台计算机 IP 设置为主机...输入的 Uri 是在 DiscoveryClient.Find(...) 响应中返回的那个。

如果你仍然需要这个，事实证明，你可以在 baseAddress 中使用通配符：

<add baseAddress = "http://*:8732/Design_Time_Addresses/NameService/GetNameService/" />
