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。每当我向代理触发open()时,它都会抛出以下错误
服务器已拒绝客户端凭据
内部异常:System.Security.Authentication.InvalidCredentialException:服务器 拒绝了客户凭证 ---> 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(LazyAsyncResult lazyResult)
在System.Net.Security.NegotiateStream.AuthenticateAsClient(NetworkCredential 凭证,ChannelBinding绑定,String targetName,ProtectionLevel requiredProtectionLevel,TokenImpersonationLevel allowedImpersonationLevel)
在System.Net.Security.NegotiateStream.AuthenticateAsClient(NetworkCredential 凭证,String targetName,ProtectionLevel requiredProtectionLevel,TokenImpersonationLevel allowedImpersonationLevel)
在System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider.WindowsStreamSecurityUpgradeInitiator.OnInitiateUpgrade(Stream stream,SecurityMessageProperty& remoteSecurity)
尝试寻找解决方案,但没有符合我的要求,因此发布了。
请帮忙......
更新1:
@ A.R。,尝试使用
client.ClientCredentials.Windows.AllowedImpersonationLevel =
System.Security.Principal.TokenImpersonationLevel.Impersonation;
但无济于事。
更新2:

感谢您的帮助。经过几天的一些研究和试验n错误方法后我得到了答案:)我知道我发布答案的时间已经很晚了,但我认为它迟到总比没有好。
所以这是解决方案
我必须对配置文件(客户端和服务器)进行一些更改
在客户端,我添加了<security>
标记,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>
并在服务器端添加了相同的标记(WCF服务配置),如下所示
<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>
希望这能帮助有需要的人:)
所以KEY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呼叫服务没有适当的凭据,就像从WinForms调用时所拥有的那样。你需要的是一些冒充。它需要一些设置,并且有点烦人,但它会起作用。
幸运的是,MSDN有一个很好的小练习 http://msdn.microsoft.com/en-us/library/ms731090.aspx
这里有一些关于这个主题的更一般的信息:

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();
}

请注意安全节点。
<bindings>
<netTcpBinding>
<binding name="customTcpBinding" maxReceivedMessageSize="20480000" transferMode="Streamed" >
<security mode="None"></security>
</binding>
</netTcpBinding>
</bindings>
答案 3 :(得分:1)
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服务未使用指定的权限运行或传递的凭据无效。尝试使用Fiddler检查您的请求,当您使用winforms vs Windwos服务时,请查看差异。
