使用WCF双工服务网的TCP："流安全需要..." [英] WCF duplex service using net tcp: "Stream Security is required..."

问题描述

我正在写一个服务，它允许用户通过其注册，当事件发生时收到通知。我试图用NetTcpBinding的做到这一点，但让我的本地机器上运行时想出的错误，甚至。

I'm writing a service that allows users to register with it and receive notifications when an event happens. I'm trying to do this with netTcpBinding, but keep coming up with errors, even when running on my local machine.

当我尝试发送一个通知，我超时，收到此错误：

When I try to send a notification, I am timing out, getting this error:

流安全需要是的 http://www.w3.org/2005/08/addressing/anonymous ，但没有安全上下文进行了谈判。这可能是由远程端点丢失其绑定StreamSecurityBindingElement引起的。

Stream Security is required at http://www.w3.org/2005/08/addressing/anonymous, but no security context was negotiated. This is likely caused by the remote endpoint missing a StreamSecurityBindingElement from its binding.

有关测试，我在一个控制台托管的服务，它是开放对我来说，我可以看到它的WSDL和运行SvcUtil工具。当我运行客户端，虽然，试图发送一个通知是当上述错误显示出来。

For testing I am hosting the service in a console, and it is opening for me and I can see the WSDL and run svcutil on it. When I run the client though, and try to send a notification is when the error above shows up.

主机的App.config：

Host 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>

下面是客户端应用程序。配置：

Here is the client 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>

我省略了很多注册代码，因为我只是想获得通知，现在的工作。

I've omitted a lot of the registration code since I am only trying to get the notification working right now.

我们的计划是在2003年服务器的Windows服务，它不是一部分举办这个。客户的域（他们的设置），并在客户端的计算机将客户的域名

The plan is to host this in a windows service in 2003 Server that is not part of the customer's domain (their setup), and the client computers will be on the customer's domain.

编辑：

我已经添加了绑定到主机的App.config中：

I have added the bindings to the host's 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>

这仍然错误，用相同的蒸汽安全需要的错误消息。 。尝试此应用程序在一个新的解决方案的一小部分。

This still errors, with the same Steam Security is required error message. Trying a small subset of this app in a new solution.

推荐答案

那么，你的问题似乎是这样的：

Well, your problem appears to be this:

• 在服务器端，您可以使用一个默认的netTCP不带参数绑定 - 你不改变任何事情。 netTCP默认传输级安全性与Windows凭据

• on the server side, you use a default netTCP binding with no parameters - you don't change anything on it. netTCP defaults to transport-level security with Windows credentials

你的客户。但是，你显式关闭的netTCP结合

on your client however, you explicitly turn OFF any security on the netTCP binding

因此，两者不匹配，不要做什么达成一致。

So the two don't match and don't agree on what to do.

要么你需要关掉两端都安全 - 服务器和客户端 - 或者你只是需要使用安全默认值（使用Windows凭据）

Either you need to turn OFF all security on BOTH ends - server AND client - or you need to just use the secure defaults (with Windows credentials).
