WCF绑定netTcpBinding寄宿到IIS

继续沿用上一篇随笔中WCF服务类库 Wettery.WcfContract.Services

WCF绑定netTcpBinding寄宿到控制台应用程序

服务端

添加WCF服务应用程序 Wettery.WcfIISHost.Services，其中添加两个WCF服务，GameService.svc  PlayerService.svc，删掉契约接口和 .cs内嵌文件，只留下.svc文件

我们通过Autofac注入契约/服务的依赖关系，Nuget引用

Install-Package Autofac.Wcf

修改两个svc文件的ServiceHost声明

<%@ ServiceHost Language="C#" Debug="true"
    Service="Wettery.WcfContract.Services.IGameService, Wettery.WcfContract.Services"
    Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %>

<%@ ServiceHost Language="C#" Debug="true"
    Service="Wettery.WcfContract.Services.IPlayerService, Wettery.WcfContract.Services"
    Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %>

添加 Global.asax，修改 Application_Start 方法，程序启动时就注入依赖关系

protected void Application_Start(object sender, EventArgs e)
{
    var builder = new ContainerBuilder();
    //注册其它依赖关系
    //....

    //注册WCF服务依赖关系
    var wcfAssembly = typeof(GameService).Assembly;
    builder.RegisterAssemblyTypes(wcfAssembly).AsImplementedInterfaces().AsSelf();
    var container = builder.Build();
    AutofacHostFactory.Container = container;
}

服务端配置

修改Web.config中system.serviceModel节

<system.serviceModel>
    <services>
      <service name="Wettery.WcfContract.Services.GameService" behaviorConfiguration="mex">
        <endpoint address="" binding="netTcpBinding" contract="Wettery.WcfContract.Services.IGameService" bindingConfiguration="netTcpBindingConfig"></endpoint>
        <!--为net.tcp绑定提供元数据-->
        <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
      </service>
      <service name="Wettery.WcfContract.Services.PlayerService" behaviorConfiguration="mex">
        <endpoint address="" binding="netTcpBinding" contract="Wettery.WcfContract.Services.IPlayerService" bindingConfiguration="netTcpBindingConfig"></endpoint>
        <!--为net.tcp绑定提供元数据-->
        <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <bindings>
      <netTcpBinding>
        <binding name="netTcpBindingConfig" transferMode="Buffered" portSharingEnabled="true">
          <readerQuotas maxStringContentLength="6553600" />
          <security mode="None" />
        </binding>
      </netTcpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mex">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

IIS配置

因为IIS默认不支持非HTTP协议，所以要开启非HTTP功能，“打开或关闭Windows功能”中选中HTTP和非HTTP激活

编译WCF应用程序，在IIS中添加一个站点，指向WCF目录，绑定两个协议，HTTP用21335端口，NET.TCP用21336端口

站点，高级设置中启用net.tcp协议

客户端测试

还是用wcftestclient工具测试，WCF服务元数据地址：

http://localhost:21335/GameService.svc
http://localhost:21335/PlayerService.svc

如果Invoke发生错误

通常是没开启这两个服务，开启即可
