Question

我正在使用wsDualHttpBinding，服务器是自托管的。我遇到一个问题，在我看来我的客户端的ClientBaseAddress无法访问。我无法解决这个问题。

这是我的服务配置：

<system.serviceModel>
<services>
  <service name="GuiEndpoint.GuiService">
    <endpoint address="" 
              binding="wsDualHttpBinding"
              bindingConfiguration="GuiEndpoint" 
              name="dualHttpBinding" 
              contract="Common.IGuiService">
      <!--<identity>
        <dns value="localhost"/>
      </identity>-->
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" name="mex" contract="IMetadataExchange"/>
    <host>
      <baseAddresses>
        <add baseAddress="http://192.168.1.199:8733/Design_Time_Addresses/GuiEndpoint/IGuiService/"/>
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="True"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <wsDualHttpBinding>
    <binding name="GuiEndpoint">
      <security mode="None">
        <message clientCredentialType="None"/>
      </security>
    </binding>
  </wsDualHttpBinding>
</bindings>
<diagnostics>
  <messageLogging logEntireMessage="true"
                  maxMessagesToLog="300"
                  logMessagesAtServiceLevel="true"
                  logMalformedMessages="true"
                  logMessagesAtTransportLevel="true" />
</diagnostics>

在我的客户端，我正在以编程方式连接此代码：

WSDualHttpBinding binding = new WSDualHttpBinding();

binding.Security.Mode = WSDualHttpSecurityMode.None;
binding.Security.Message.ClientCredentialType = MessageCredentialType.None;
binding.ClientBaseAddress = new Uri("192.168.1.189:8080/TempUri");

EndpointAddress endpoint = new EndpointAddress(Helper.CreateUri(client.Connection.ServerAddress));

context = new InstanceContext(this);

serviceClient = new GuiServiceClient(context, binding, endpoint);
serviceClient.InnerDuplexChannel.Faulted += InnerChannelOnFaulted;

try
{
    if (serviceClient.Subscribe())
    {
        startKeepAliveTimer();
    }
}
catch (EndpointNotFoundException)
{
    this.Error("Couldn't Connect!");
}

现在，使用Fidler我可以看到消息来回传递。

服务器： enter image description here

客户端： enter image description here

如您所见，客户端可以与服务器通信，但服务器似乎无法与客户端通信。

我还在客户端上注册了命名空间：

客户端端口也可以访问：

Starting Nmap 6.25 ( http://nmap.org ) at 2013-01-03 14:05 Mountain Standard Time

Nmap scan report for 192.168.1.189

Host is up (0.10s latency).

PORT     STATE SERVICE

8080/tcp open  http-proxy

MAC Address: xx:0B:A9:57:xx:xx (Intel Corporate)

Nmap done: 1 IP address (1 host up) scanned in 13.42 seconds

这里的任何帮助都会很棒！

Answer 1

Microsoft没有在任何文档中添加的内容是：

您在ClientBaseAddress中指定的IP地址必须可解析为主机名。换句话说，如果服务器无法通过其主机名称ping客户端，那么您将永远无法建立连接。

正如您所发现它只是不起作用！

尝试将192.168.1.189替换为客户端PC的主机名，如下所示：

 http://ClientHostName:8080/TempURI

另外，如果您不想注册任何端口，请使用地址

http://MyClientHostName/Temporary_Listen_Addresses/TempUri

因为您可以注册以

开头的任何网址

http://+80/Temporary_Listen_Addresses/

ClientBaseAddress似乎不可访问
