Question

我有一个双工WCF，它在本地主机上运行完美（在本地运行时将我的应用程序连接到此WCF）。

现在我尝试在我的IIS（Server 2008 R2标准）中托管它，我创建了一个Windows帐户“GOD”，并使用“GOD”标识在IIS中进行应用程序轮询。

我可以从我的电脑（除了服务器）从网络浏览器访问这个WCF并查看合同的XML，（点击显示的页面内的链接）

当我尝试从我的应用程序访问时，我得到了例外：

客户端无法完成安全协商配置超时（00:00:00）。目前的谈判支持是1 （00:00:00）。

当WCF在本地运行时，我的应用程序工作正常。

我试图使用跟踪，但我成功看到的只是关于超时的例外。

我的app.config是：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">

          <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\log\Traces.svclog"/>
        </listeners>
      </source>
    </sources>
  </system.diagnostics>
  <system.serviceModel>
    <bindings>
      <wsDualHttpBinding>
        <binding name="WSDualHttpBinding_I_BridgeWCFService" closeTimeout="00:01:00"

          <reliableSession ordered="true" inactivityTimeout="01:10:00" />
          <security mode="Message" />
        </binding>
      </wsDualHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://win-jj/_Bridge1/_BridgeWcfService.svc"
        binding="wsDualHttpBinding" bindingConfiguration="WSDualHttpBinding_I_BridgeWCFService"
        contract="_BridgeWcfServiceReference.I_BridgeWCFService"
        name="WSDualHttpBinding_I_BridgeWCFService">
        <identity>
          <dns value="localhost"/>
        </identity>

    </client>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/>
  </startup>
</configuration>

我还尝试将上面的标识部分更改为：<userPrincipalName value="GOD" />，但后来又出现了另一个异常。

我的服务配置文件：web.config：

<?xml version="1.0"?>
<configuration>
  <system.serviceModel>
    <bindings>
      <wsDualHttpBinding>
        <binding name="WSDualHttpBinding_I_BridgeWCFService" closeTimeout="01:01:00" openTimeout="01:01:00" receiveTimeout="01:10:00" sendTimeout="01:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="2147483646" maxReceivedMessageSize="2147483646" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true">

      </service>

        <behavior name="_BridgeNameSpace.Service1Behavior">
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->

      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <system.web>
    <compilation debug="true"/>
  </system.web>
</configuration>

我还尝试将上面的标识部分更改为：<dns value="localhost"/>，但没有任何更改

我在我的应用程序中连接到我的服务，如下所示：

MyServiceClientProxy Proxy = null;
MyCallbackProxy myCallbackProxy = null;

myCallbackProxy = new MyCallbackProxy();
InstanceContext cntx = new InstanceContext(myCallbackProxy);
Proxy = new MyServiceClientProxy(cntx, "WSDualHttpBinding_I_BridgeWCFService");
Proxy.ClientCredentials.Windows.ClientCredential.UserName = "GOD";
Proxy.ClientCredentials.Windows.ClientCredential.Password = "yy";
try
{
Proxy.Open();
}
catch { return; }

顺便说一下，当试图将安全性更改为''时出现以下异常（使用ClientCredential.Username＆amp; Password作为上面的代码）：

The open operation did not complete within the allotted timeout of 00:00:59.1689524. The time allotted to this operation may have been a portion of a longer timeout.

任何想法？，PLS帮助！

Answer 1

wsDualHttpBinding尝试打开从服务器到客户端的连接，该连接将被防火墙阻止

我的建议是切换到netTcpBinding - 这对我的博客here

的双工消息传递要简单得多

WCF Duplex - 客户端无法在配置的超时内完成安全协商
