Question

我正在编写一项服务，允许用户注册并在事件发生时接收通知。我正在尝试使用netTcpBinding执行此操作，但即使在本地计算机上运行，也会遇到错误。

当我尝试发送通知时，我超时，收到此错误：

http://www.w3.org/2005/08/addressing/anonymous需要流安全性，但未协商安全上下文。这可能是由远程端点从其绑定中丢失StreamSecurityBindingElement引起的。

为了测试我在一个控制台中托管服务，它正在为我打开，我可以看到WSDL并在其上运行svcutil。当我运行客户端时，尝试发送通知是在上面的错误出现时。

主机App.config：

<system.serviceModel>
<services>
  <service name="CompanyName.WebServices.InterventionService.RegistrationService"
           behaviorConfiguration="RegistrationServiceBehavior">
    <endpoint address="http://localhost:8000/CompanyName/Registration"
              binding="wsDualHttpBinding"
              contract="CompanyName.WebServices.InterventionService.Interfaces.IRegistrationService"/>
    <endpoint address="net.tcp://localhost:8001/CompanyName/Registration"
              binding="netTcpBinding"
              contract="CompanyName.WebServices.InterventionService.Interfaces.IRegistrationService"/>
  </service>
  <service name="CompanyName.WebServices.InterventionService.NotificationService"
           behaviorConfiguration="NotificationServiceBehavior">
    <endpoint address="http://localhost:8010/CompanyName/Notification"
              binding="wsDualHttpBinding"
              contract="CompanyName.WebServices.InterventionService.Interfaces.INotificationService"/>
    <endpoint address="net.tcp://localhost:8011/CompanyName/Notification"
              binding="netTcpBinding"
              contract="CompanyName.WebServices.InterventionService.Interfaces.INotificationService"/>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="RegistrationServiceBehavior">
      <serviceMetadata httpGetEnabled="true"
                       httpGetUrl="http://localhost:8000/CompanyName/Registration"/>
    </behavior>
    <behavior name="NotificationServiceBehavior">
      <serviceMetadata httpGetEnabled="true"
                       httpGetUrl="http://localhost:8010/CompanyName/Notification"/>
    </behavior>
    <behavior name="netTcpRegistrationServiceBehavior">
      <serviceMetadata httpGetEnabled="true"
                       httpGetUrl="net.tcp://localhost:8001/CompanyName/Registration"/>
    </behavior>
    <behavior name="netTcpNotificationServiceBehavior">
      <serviceMetadata httpGetEnabled="true"
                       httpGetUrl="net.tcp://localhost:8011/CompanyName/Notification"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

这是客户端App.config：

<system.serviceModel>
<bindings>
  <netTcpBinding>
    <binding name="NetTcpBinding_IRegistrationService">
      <security mode="None">
        <message clientCredentialType="None"/>
        <transport clientCredentialType="None"/>
      </security>
    </binding>
    <binding name="NetTcpBinding_INotificationService">
      <security mode="None">
        <message clientCredentialType="None"/>
        <transport clientCredentialType="None"/>
      </security>
    </binding>
  </netTcpBinding>
  <wsDualHttpBinding>
    <binding name="WSDualHttpBinding_IRegistrationService">
      <reliableSession ordered="true"/>
      <security mode="None">
        <message clientCredentialType="None" negotiateServiceCredential="false"/>
      </security>
    </binding>
    <binding name="WSDualHttpBinding_INotificationService">
      <reliableSession ordered="true"/>
      <security mode="None">
        <message clientCredentialType="None" negotiateServiceCredential="false"/>
      </security>
    </binding>
  </wsDualHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:8000/GPS/Registration"
            binding="wsDualHttpBinding"
            bindingConfiguration="WSDualHttpBinding_IRegistrationService"
            contract="IRegistrationService"
            name="WSDualHttpBinding_IRegistrationService">
  </endpoint>
  <endpoint address="net.tcp://localhost:8001/GPS/Registration"
            binding="netTcpBinding"
            bindingConfiguration="NetTcpBinding_IRegistrationService"
            contract="IRegistrationService"
            name="NetTcpBinding_IRegistrationService">
  </endpoint>
  <endpoint address="http://localhost:8010/GPS/Notification"
            binding="wsDualHttpBinding"
            bindingConfiguration="WSDualHttpBinding_INotificationService"
            contract="INotificationService"
            name="WSDualHttpBinding_INotificationService">
  </endpoint>
  <endpoint address="net.tcp://localhost:8011/GPS/Notification"
            binding="netTcpBinding"
            bindingConfiguration="NetTcpBinding_INotificationService"
            contract="INotificationService"
            name="NetTcpBinding_INotificationService">
  </endpoint>
</client>

我省略了很多注册码，因为我现在只是想让通知正常工作。

计划是在2003 Server中的Windows服务中托管此服务，该服务不属于客户的域（他们的设置），客户端计算机将位于客户的域中。

编辑：

我已将绑定添加到主机的App.config：

<bindings>
  <netTcpBinding>
    <binding name="NetTcpBinding_IRegistrationService">
      <security mode="None">
        <message clientCredentialType="None"/>
        <transport clientCredentialType="None"/>
      </security>
    </binding>
    <binding name="NetTcpBinding_INotificationService">
      <security mode="None">
        <message clientCredentialType="None"/>
        <transport clientCredentialType="None"/>
      </security>
    </binding>
  </netTcpBinding>
  <wsDualHttpBinding>
    <binding name="WSDualHttpBinding_IRegistrationService">
      <reliableSession ordered="true"/>
      <security mode="None">
        <message clientCredentialType="None" negotiateServiceCredential="false"/>
      </security>
    </binding>
    <binding name="WSDualHttpBinding_INotificationService">
      <reliableSession ordered="true"/>
      <security mode="None">
        <message clientCredentialType="None" negotiateServiceCredential="false"/>
      </security>
    </binding>
  </wsDualHttpBinding>
</bindings>

这仍然是错误，具有相同的Steam Security是必需的错误消息。在新解决方案中尝试此应用的一小部分。

Answer 1

好吧，你的问题似乎是这样的：

在服务器端，您使用没有参数的默认netTCP绑定 - 您不会更改任何内容。 netTCP默认使用Windows凭据传输级别的安全性
在您的客户端上，您明确关闭netTCP绑定的任何安全性

所以两者不匹配，不同意该做什么。

您需要关闭BOTH端的所有安全性 - 服务器和客户端 - 或者您只需使用安全默认值（使用Windows凭据）。

Answer 2

我认为事实证明这是导致你进入许多不同方向的那些可怕的错误信息之一。上述答案对于这种情况是正确的。我的情况不同 - 我的安全设置在客户端和服务上是相同的。

就我而言，这个链接指出了我的特殊缺陷：http://www.netframeworkdevs.com/windows-communication-foundation-wcf/error-invoking-service-with-a-net-tcp-binding-123918.shtml。

我的端点的服务端app.config有bindingName作为命名绑定配置的属性...而不是bindingConfiguration。我不认为endpoint上有一个名为 bindingName 的属性。

所以......我带走的是这个错误意味着＆＃34;有一个WCF配置错误＆＃34;也许缩小到服务端配置。啊。

使用net tcp的WCF双工服务：“需要Stream Security ......”
