我可以使用 Win-form 应用程序连接到我的 WCF 服务,但是我无法使用我的 Windows 服务来连接。每当我向代理触发 open() 时,它都会引发以下错误

服务器已拒绝客户端凭据

内部异常:System.Security.Authentication.InvalidCredentialException:服务器已拒绝客户端凭据。
---> System.ComponentModel.Win32Exception:登录尝试失败
---内部异常堆栈跟踪结束---
在 System.Net.Security.NegoState.ProcessAuthentication(LazyAsyncResultlazyResult)
在 System.Net.Security.NegotiateStream.AuthenticateAsClient
System.Net.Security.NegotiateStream.AuthenticateAsClient (NetworkCredential credential, String targetName, ProtectionLevel requiredProtectionLevel, TokenImpersonationLevel allowedImpersonationLevel) 上的(NetworkCredential credential、ChannelBinding 绑定、String targetName、ProtectionLevel requiredProtectionLevel、TokenImpersonationLevel allowedImpersonationLevel)
在 System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider.WindowsStreamSecurityUpgradeInitiator.OnInitiateUpgrade(流流、SecurityMessageProperty 和 remoteSecurity)

尝试搜索解决方案,但不符合我的要求,因此发布。

请帮忙...

更新1:

@AR,尝试使用

client.ClientCredentials.Windows.AllowedImpersonationLevel =
    System.Security.Principal.TokenImpersonationLevel.Impersonation;

但无济于事。

感谢你的帮助。经过几天的研究和尝试 n 错误方法后,我得到了答案 :) 好吧,我知道我迟到了,但我认为迟到总比没有好。

所以这是解决方案

我必须对我的配置文件(客户端和服务器)进行一些更改

在客户端,我添加了<security>标签,如下所示

  <system.serviceModel>
    <bindings>
      <netTcpBinding>
        <binding name="netTcpEndPoint" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="5242880" maxBufferSize="5242880" maxConnections="15" maxReceivedMessageSize="5242880">
          <readerQuotas maxDepth="32" maxStringContentLength="5242880" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
         <security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
            <message clientCredentialType="Windows" />
          </security>
        </binding>
      </netTcpBinding>
    </bindings>
    <client>
      <endpoint address="net.tcp://xx.xx.xx.xx:8010/WCFService.CollectorService/" binding="netTcpBinding" bindingConfiguration="netTcpEndPoint" contract="CloudAdapter.CloudCollectorService.ICollectorService" name="netTcpEndPoint">
      </endpoint>
    </client>
  </system.serviceModel>

并且还在服务器端添加了相同的标签(WCF服务配置),如下图

<bindings>
  <netTcpBinding>
    <binding name="myBindingForLargeData" maxReceivedMessageSize="5242880" maxConnections="10">
      <readerQuotas maxDepth="64" maxStringContentLength="5242880" maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
         <security mode="Transport">
        <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
        <message clientCredentialType="Windows" />
      </security>
    </binding>
  </netTcpBinding>
</bindings>

希望这可以帮助有需要的人:)

所以关键是使<security>标签在客户端和服务器配置文件上相同。

基本上发生的事情是您的调用服务没有适当的凭据,就像从 WinForms 调用时那样。你需要的是一些模仿。它需要一些设置,并且有点烦人,但它会起作用。

幸运的是,MSDN 有一个不错的小演练。

这里有一些关于这个主题的更一般的信息:http:

更新:
设置模拟标志是不够的。您必须实际模拟凭据才能使其正常工作。例如:

  // Let's assume that this code is run inside of the calling service.
  var winIdentity = ServiceSecurityContext.Current.WindowsIdentity;
  using (var impContext = winIdentity.Impersonate())
  {
    // So this would be the service call that is failing otherwise.
    return MyService.MyServiceCall();
  }

查看我在这篇文章中的回答 服务器已拒绝客户端凭据

注意安全节点。

<bindings>
  <netTcpBinding>
    <binding name="customTcpBinding" maxReceivedMessageSize="20480000" transferMode="Streamed" >
      <security mode="None"></security>
    </binding>
  </netTcpBinding>
</bindings>

您在 WCF 服务上使用的身份验证模式是什么?似乎 winform 应用程序正在运行并提供正确的凭据,而您的 Windows 服务未以指定的权限运行或传递的凭据无效。当您从 winforms 与 Windwos 服务制作时,尝试使用 Fiddler 检查您的请求,并查看差异。

对我来说,它有助于将双方(客户端+服务器)的安全模式设置为无:

NetTcpBinding 绑定 = new NetTcpBinding(); binding.Security.Mode = SecurityMode.None;

(与 spinner_den_g 的答案相同,但在 C# 中 - 无需编辑 app.config)
