wcf - 使用 Net.TCP 托管 WCF 服务

Question

我对此完全陌生，并尝试使用 net.tcp 绑定(bind)托管最简单的 WCF 服务
我有 Windows 7 Professional 和 IIS7 并启用了非 http 激活。

我启动了一个新的 WCF 服务应用程序
vs2010中的项目并编译它。
没有别的!

我删除了我所有的 IIS
网站并添加一个新的名为 WCFHost

我打开 WcfTestClient.exe 并添加
http://localhost/Service1.svc应用程序找到它

Web.config 看起来像这样(未改动)

 <system.serviceModel>
    <services>
      <service name="WcfService2.Service1" behaviorConfiguration="WcfService2.Service1Behavior">
        <endpoint address="" binding="wsHttpBinding" contract="WcfService2.IService1">
          <!-- 
              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>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WcfService2.Service1Behavior">
          <!-- 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>

到现在为止还挺好。但是那个 net.tcp 绑定(bind)呢？我添加了“enabledProtocols”属性，所以我的 applicationHost.config 看起来像这样

       <site name="WCFHOST" id="3">
            <application path="/" applicationPool="WCFHOST" enabledProtocols="http,net.tcp,net.pipe,net.msmq">
                <virtualDirectory path="/" physicalPath="C:\Prosjekter\temp\TestService\TestService" />
            </application>
            <bindings>
                <binding protocol="net.tcp" bindingInformation="808:*" />
                <binding protocol="http" bindingInformation="*:80:" />
            </bindings>
        </site>

然后我去IIS WCFHost网站并添加绑定(bind)net.tcp 808:*
然后我修改我的 web.config 以使 WCF 服务看起来像这样。 (只是更改了端点上的绑定(bind))

<system.serviceModel>
    <services>
      <service name="WcfService2.Service1" behaviorConfiguration="WcfService2.Service1Behavior">
        <!-- Service Endpoints -->
        <endpoint address="" binding="netTcpBinding" contract="WcfService2.IService1">
          <!-- 
              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>
        <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WcfService2.Service1Behavior">
          <!-- 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>

当我现在尝试在我的 WcfTestClient.exe 中添加服务 net.tcp://localhost:808/Service1.svc 时出现错误

错误:无法从 net.tcp://localhost/Service1.svc 获取元数据
TCP-errorcode 10061:无法建立连接，因为目标机器主动拒绝它.... 127.0.0.1:808

我的防火墙已关闭。
不过，我看到了一件事.. 使用 netstat -a 时，808 端口未在此处列出.. 应该吗？

有人可以帮助我使用 nettcp 绑定(bind)创建我的第一个 WCF 服务吗？

Answer 1

正如 Tocco 所说，检查服务是否正在运行。您可以通过检查来做到这一点:

netstat /an | find /i "808 "

它应该显示:

TCP 0.0.0.0:808 0.0.0.0:0 LISTENING
TCP [::]:808 [::]:0 LISTENING

如果服务正常运行。

如果它还没有工作，要让它开始，你可以发出:

sc start NetTcpActivator

从命令行尝试启动它。

在此之前，请确保 the non-HTTP activation windows components are installed .

还要检查服务是否实际运行。 I had a problem where they would not necessarily start after a reboot.
