Question

我有一个WCF服务，includeExceptionDetailInFaults设置为true。当我在SOAP UI中测试服务时，我可以看到响应包含错误：

<ExceptionDetail xmlns="http://schemas.datacontract.org/2004/07/System.ServiceModel"    xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
   <HelpLink i:nil="true"/>
   <InnerException i:nil="true"/>
   <Message>Invalid Session Protocol</Message>

然而，我的客户只是选择了一个非常沉闷的

远程服务器返回了意外响应：（400）Bad Request。

消息。因此，我必须在客户端中执行某些操作，以使其能够从服务中读取响应。

我的服务配置是：

           contract="DRGDataLibrary.IStoreDataDotNet" />
       </service>
    </services>
</system.serviceModel>

（在这个配置中有一点点，因为我正在使用SSL并对服务进行JS调用）

你捕捉到什么异常类型？如果它只是一个非泛型FaultException，则无法访问该服务提供的任何特定于故障的详细信息。

当您启用includeExceptionDetailInFaults时，看起来WCF使用ExceptionDetail数据合同来编码您在SoapUI中看到的信息，这意味着您应该能够通过捕获{来获取它{1}}并检查异常的FaultException<ExceptionDetail>属性。

所有这一切，official recommendation仅使用Detail进行调试，build better error-reporting mechanisms使用自定义错误合同和includeExceptionDetailInFaults - 因此，您的客户是否应该是无论如何依赖IErrorHandler中的信息。

WCF客户端没有从服务中获得异常
