WCF较新版本侦听先前版本的地址并引发异常 [英] WCF newer version to listen on previous version address and throw exception

问题描述

你好

  我们在服务器上升级了服务，它在新的端点上进行侦听.我希望新服务在较旧的终结点上(在基本地址处)侦听并引发自定义异常.我该怎么做.

  我尝试添加自定义消息过滤器并匹配To.AbsoluteUri.像这样的东西:

  如果(！message.Headers.To.AbsoluteUri.EndsWith("4.1"))
                            抛出新的ServiceUpgradedException();

  但是，客户端仅接收通用通信异常.

请咨询.

谢谢

解决方案

您好，RajPCoop，

根据您的描述，我无法直接找到解决方案.

您从何处获取异常?并且您想抓住服务器端还是客户端?

我建议您看看通用通信异常中的内部异常.

如果要在客户端获取异常，则将为服务操作创建一个FaultContract:

#定义和指定故障

#发送和接收故障

希望有帮助.

Hello,

   We upgraded our service on the server and it listens on a new endpoint.  I would like the new service to listen on the older endpoint (at base address) and throw custom exception.  How can I accomplish this.

   I tried adding a custom message filter and match the To.AbsoluteUri.  Something like this: 

    if (!message.Headers.To.AbsoluteUri.EndsWith("4.1"))
                throw new ServiceUpgradedException();

   However, the client is only receiving a generic communication exception.

Please advice.

Thank you

解决方案

Hi RajPCoop,

According to your description I cannot reach the solution directly.

Where do you get the catch the exception? And do you want to catch at server-side or Client-side?

I suggest you to have a look at the inner exception in the generic communication exception.

If you want to get the exception at client side , you would create a FaultContract for the service operation:

#Defining and Specifying Faults

#Sending and Receiving Faults

Hope helpful.
