c# - 如何使用具有相同合同和绑定的动态端点创建多个 wcf 服务实例而不保存在 app.config 中？

Question

这是我的服务器端app.config：

<services>
  <service name="PokerService.PlayerService" behaviorConfiguration="ServiceBehaviorPlayer">
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:5054" />
      </baseAddresses>
    </host>
    <!-- Service Endpoints -->
    <endpoint  address="player" binding="netTcpBinding" bindingConfiguration="PlayerBinding" contract="PokerService.IPlayerService" />
    <endpoint address="player/mex" binding="mexTcpBinding" name="ServiceBehaviorPlayer" contract="IMetadataExchange"  />
  </service>
</services>

我正在客户端代码中生成动态端点：

ServiceHost host = new ServiceHost(typeof(PokerService.PlayerService));

NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message);
binding.Name = "NetTcpBinding_IPlayerService";
binding.Security.Message.ClientCredentialType = MessageCredentialType.IssuedToken;

ServiceEndpoint ep = host.AddServiceEndpoint(
            typeof(PokerService.IPlayerService),
            binding,
            "net.tcp://localhost:5054");
        EndpointAddress myEndpointAdd = new EndpointAddress(new Uri("net.tcp://localhost:5054/player1"),
             EndpointIdentity.CreateDnsIdentity("pident.cloudapp.net"));
        ep.Address = myEndpointAdd;

对于服务测试代码：

var PlayerChannelFactory = new DuplexChannelFactory<ClientApplication.PlayerService.IPlayerService>(new PlayerHandler(handler, this), binding, ep.Address);

PlayerChannelFactory.Credentials.SupportInteractive = false;
        PlayerChannelFactory.Credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
PlayerServiceProxy = PlayerChannelFactory.CreateChannelWithIssuedToken(User.Instance.userToken);

现在我收到此错误

任何想法？

Answer 1

客户端配置文件如下所示：

<client>
      <endpoint address="net.tcp://localhost:5054/player" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IPlayerService" contract="PlayerService.IPlayerService" name="NetTcpBinding_IPlayerService">
      <identity>
          <dns value="pident.cloudapp.net"/>
        </identity>
      </endpoint>
         </client>

Answer 2

我还认为您的服务和客户端之间存在端点不匹配。尝试：

new EndpointAddress(new Uri("net.tcp://localhost:5054/player")

客户端配置文件长什么样？

由于您可以在同一地址上托管多个服务（使用端口共享，...） - 您的服务端点地址定义了“您正在寻找哪些服务”。

因此，正如@Backlash 还提到的，您的客户端的 uri 应该指向正确的服务器地址。
