IIS Hosting中的WCF库未从客户端连接

[英]WCF Library in IIS Hosting not connecting from client

您好,我有一个WCF服务库项目,并且我已经创建了一个WPF应用程序来承载它进行测试,并且效果很好,但是我还创建了一个Web应用程序来承载它在IIS中进行生产,以及尝试连接到IIs时我永远做不到

我正在使用net.tcp bininding,并且已经进入IIS,并将net.tcp biniding添加到Web应用程序和网站中。

基本上,这是一种双工服务,其方法标记为一种方法。 当我在客户端中调用该方法时,永远不会调用该回调,而最终我只是坐在那里等待了几分钟,然后关闭了应用程序。 当我自托管服务时,几乎立即在回调上得到响应。

我也尝试使用localhost:808和localhost。 如果我使用svcutil生成配置,它将使端口脱离地址。 我没有发现任何错误,但是老实说我真的不知道如何判断是否从IIS抛出了任何错误。

另外,如果我转到http://localhost:9595/EcuWebService/Service.svc看到告诉我使用svcutil生成客户端代理的页面。

正如Jocke在下面建议的那样,我连接了调试器并收到此错误:服务'/ EcuWebService / service'不存在。

这也是我的svc文件的内容:

<%@ ServiceHost Language="C#" Debug="true" Service="EcuWeb.ServiceLib.Contracts.EcuWebServiceMain" %>

下面是我的Web.config:

<?xml version="1.0"?>
  <configuration>

                </identity>
            </endpoint>
            <endpoint address="net.tcp://localhost:808/EcuWebService/mex" binding="mexTcpBinding" bindingConfiguration="" name="mexTcp_EcuWebServiceEndpoint" contract="IMetadataExchange" />
            <host>
               <baseAddresses>
                  <add baseAddress="http://localhost/EcuWebService" />
                </baseAddresses>
            </host>
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>

这是客户端应用程序的配置。 注释掉的终结点是我不在IIS中托管时使用的终结点,并且可以正常工作。

<?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>
       <bindings>
        <netTcpBinding>
          <binding name="netTcp_EcuWebServiceEndpoint" />
        </netTcpBinding>
       </bindings>
     <client>
      <!--<endpoint address="net.tcp://localhost:5555/EcuWebService/service"
       binding="netTcpBinding" bindingConfiguration="netTcp_EcuWebServiceEndpoint"
       contract="EcuWebService.IEcuWebServiceMain" name="netTcp_EcuWebServiceEndpoint">
        <identity>
         <dns value="localhost" />
        </identity>
       </endpoint>-->
         <endpoint address="net.tcp://localhost/EcuWebService/service"
            binding="netTcpBinding" bindingConfiguration="netTcp_EcuWebServiceEndpoint"
            contract="EcuWebService.IEcuWebServiceMain"    name="netTcp_EcuWebServiceEndpoint">
            <identity>
                <dns value="localhost" />
            </identity>
        </endpoint>
</client>
<services>
  <service name="Ecu.Service.Contracts.EcuServiceMain">
    <endpoint address="service" binding="netNamedPipeBinding" bindingConfiguration=""
      name="netNamedPipe_EcuClientEndpoint" contract="Ecu.Service.Contracts.IEcuServiceMain">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexNamedPipeBinding" bindingConfiguration=""
      name="mexNamedPipe_EcuClientEndpoint" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.pipe://localhost/EcuServiceClient" />
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
   <serviceBehaviors>
     <behavior name="">
       <serviceMetadata httpGetEnabled="false" />
         <serviceDebug includeExceptionDetailInFaults="true" />
     </behavior>
   </serviceBehaviors>
 </behaviors>

好吧,我终于明白了。

首先,我必须添加:

<host>
 <baseAddresses>
  <add baseAddress="net.tcp://localhost:5555/EcuWebService" />
  <add baseAddress="http://localhost/EcuWebService" />
 </baseAddresses>
</host>

然后对于我刚刚使用的端点:

<service name="EcuWeb.ServiceLib.Contracts.EcuWebServiceMain">
<endpoint address="service" binding="netTcpBinding" bindingConfiguration=""
 name="netTcp_EcuWebServiceEndpoint" contract="EcuWeb.ServiceLib.Contracts.IEcuWebServiceMain">
 <identity>
  <dns value="localhost" />
 </identity>
</endpoint>

然后在客户端中,我必须使用:

<endpoint address="net.tcp://localhost/EcuWebService/Service.svc/service"
    binding="netTcpBinding" bindingConfiguration="netTcp_EcuWebServiceEndpoint"
    contract="EcuWebService.IEcuWebServiceMain" name="netTcp_EcuWebServiceEndpoint">
            <identity>
                <dns value="localhost" />
            </identity>
        </endpoint>

当我添加端口时,它不起作用,但是一旦删除它,它就没有问题。 我也怀疑基址是必需的,因为IIS无论如何都给出了该地址。

怎么了? 你有例外吗? 您可以在IIS中浏览它吗?

您的服务有:

endpoint address="net.tcp://localhost:808/EcuWebService/mex"

和客户:

endpoint address="net.tcp://localhost/EcuWebService/service"

我认为您需要提供更多详细信息才能获得良好的答案。
