WCF 身份验证和套​​接字中止异常

发布于 2024-09-12 11:39:02 字数 1044 浏览 3 评论 0原文

这是该项目的设置。

我有一个 WCF 服务,以缓冲模式托管在 net.tcp 绑定上,并启用了 ReliableSession。

绑定配置为使用 TransportWithMessageCredential 安全性。该证书是我使用指纹识别的自签名证书。 UserNameValidator 是一个自定义验证器,用于测试,永远不会失败(之前没有失败,但我消除了不确定性)

服务和客户端位于同一台计算机上,并且它们都可以访问证书。

问题:

当我尝试从服务中使用方法时,我收到了 Socket Aborted 异常。这是我用来打开服务连接的代码。 MonitorServiceCallbacks 仅包含空方法来满足接口的要求。

 _instanceContext = new InstanceContext(new MonitorServiceCallbacks());
 _serviceInterface = new MonitorCallbackServiceClient(_instanceContext);

 _serviceInterface.ClientCredentials.UserName.UserName = Environment.MachineName;
 _serviceInterface.ClientCredentials.UserName.Password = "myPassword";
 _serviceInterface.Open();

这似乎工作正常,因为 _serviceInterface.State 变量设置为 State.Opened 并且调用自定义验证器并毫无例外地返回。

但是,如果我尝试使用 _serviceInterface 代理调用方法,则该服务上不会运行我可以闯入的代码,并且除了 SocketAborted 异常之外,跟踪日志不会显示任何错误,该异常在收到似乎是以下消息后 1 分钟发生的方法。

没有内部异常。

我尝试用谷歌搜索这个问题,但结果往往是“只要禁用安全性,它就会正常工作”。不幸的是,这无法做到。

我对这个问题感到非常困惑,任何帮助将不胜感激。

非常感谢,
埃里斯

here's the setup for the project.

I have a WCF Service that is hosted on a net.tcp binding in buffered mode and ReliableSession enabled.

The binding is configured to use TransportWithMessageCredential security. The certificate is a self signed certificate that I am identifying using the Thumbprint.
The UserNameValidator is a custom validator which for testing, never fails (it wasn't failing before but I removed the uncertainty)

The service and client are on the same machine and they both have access to the certificate.

The problem:

I am receiving a Socket Aborted exception when trying to consume a Method from the service. Here is the code I use to open a connection to the service. MonitorServiceCallbacks only contains empty methods to fulfil the requirements of the Interface.

 _instanceContext = new InstanceContext(new MonitorServiceCallbacks());
 _serviceInterface = new MonitorCallbackServiceClient(_instanceContext);

 _serviceInterface.ClientCredentials.UserName.UserName = Environment.MachineName;
 _serviceInterface.ClientCredentials.UserName.Password = "myPassword";
 _serviceInterface.Open();

This appears to work fine as the _serviceInterface.State variable is set to State.Opened and the custom validator is called and returns without exception.

However, if I try to call a method using the _serviceInterface proxy, no code that I can break into is run on the service and the tracelog reveals no errors apart from a SocketAborted exception which occurs 1 minute after receiving what appears to be the message for the method.

There is no InnerException.

I have tried to google the issue but the results tend to say "just disable security and it will work fine". Unfortunately, this cannot be done.

I am extremely confused by this issue and any help would be greatly appreciated.

Many thanks,
Ehrys

这实际上是一个序列化错误。

我试图发送到从数据协定继承的服务的对象。所以我试图将数据契约的转换发送到服务。

WCF 似乎不允许这样做。

我要感谢 John Saunders 提醒我,不仅服务可以启用跟踪。启用客户端跟踪会节省我很多时间。

我试图做以下事情:

_serviceInterface.Register((MyDataContract)MyParentObject, aVariable, anotherOne);

我需要做什么:

MyDataContract tempContract = MyParentObject.CreateMyDataContract();
_serviceInterface.Register(tempContract, aVariable, anotherOne);
/* Note: MyParentObject.CreateMyDataContract() is my own method which creates an instance
of the MyDataContract and copies the relevant information to it */

This was actually a serialisation error.

The object I was trying to send to the service inherited from the data contract. So I was trying to send a cast down to the data contract to the service.

WCF doesn't appear to allow this.

I would like to thank John Saunders for reminding me that not only the service can have tracing enabled. Enabling client side tracing would have saved me a lot of time.

I was attempting to do the following:

_serviceInterface.Register((MyDataContract)MyParentObject, aVariable, anotherOne);

What I needed to do:

MyDataContract tempContract = MyParentObject.CreateMyDataContract();
_serviceInterface.Register(tempContract, aVariable, anotherOne);
/* Note: MyParentObject.CreateMyDataContract() is my own method which creates an instance
of the MyDataContract and copies the relevant information to it */
