如何从 WCF 客户端访问 SOAP 1.1 故障详细信息(无故障合同) [英] How to access SOAP 1.1 fault detail from WCF client (no fault contract)

问题描述

我正在访问 SOAP 1.1 Web 服务，但它返回了一个错误.据我所知，Web 服务没有在 WSDL 中定义任何错误契约.我的 WCF 客户端将故障映射到 FaultException(而不是 FaultException).这都是有道理的.问题是该服务正在故障的 detail 元素中返回一些有用的诊断信息，我想访问这些信息以便我可以将其转储到跟踪日志中.似乎 FaultException 不提供对 detail 元素的任何访问，大概是因为没有错误合同，它不知道那里有什么.

I'm accessing a SOAP 1.1 web service, and it's returning a fault. The web service does not define any fault contract in the WSDL as far as I can see. My WCF client maps the fault to a FaultException (rather than a FaultException<T>). This all makes sense. The problem is that the service is returning some useful diagnostic information in the detail element of the fault, which I'd like to access so that I can dump it to a trace log. It seems that FaultException does not provide any access to the detail element, presumably because without a fault contract it doesn't know what is in there.

但我不需要反序列化细节 XML - 只需将原始 XML 作为字符串就可以用于诊断目的.

But I don't need to deserialize the detail XML - just the raw XML as a string will do fine for diagnostic purposes.

在这种情况下，有没有办法从 WCF 客户端访问详细的 XML?

Is there any way to get access to the detail XML from a WCF client, in this scenario?

推荐答案

详见此处:http://www.theruntime.com/blogs/jacob/archive/2008/01/28/getting-at-the-details.aspx

您可以使用此解决方法获取详细信息:

you can use this workaround to obtain the details:

} catch (FaultException soapEx)
{    
    MessageFault mf = soapEx.CreateMessageFault();    
    if (mf.HasDetail)
    {    
        XmlDictionaryReader reader = mf.GetReaderAtDetailContents();    
        ...    
    }    
}
