当我处理服务外发生的异常时,我是否有权访问请求 dto?

Do I have access to the request dto when I'm handling exceptions occuring outside of services?

对于 ServiceStack,在两个地方实现异常 handling/logging 很重要:

  1. Inside of each ServiceRunner<T>.

       public class MyServiceRunner<T> : ServiceRunner<T>
       {    
            public override object HandleException(IRequestContext requestContext, T request, Exception ex)
              {
                    // Implement your exception handling/logging here.
                    // T request is your request DTO.
              }
        }
    
  2. Inside of AppHost,以便您可以处理在服务之外发生的未处理异常。

    public override void Configure(Container container)
    {
        ExceptionHandler = (req, res, operationName, ex) =>
        {
            //Handle Unhandled Exceptions occurring outside of Services
            //E.g. Exceptions during Request binding or in filters:
        }
     }
    

我的问题:

在 ServiceStack v4 中,请求 DTO 可从 IRequest.Dto 获得,但您可以使用 IAppHost.ServiceExceptionHandlersIAppHost.UncaughtExceptionHandlers

注册您的服务和未知异常处理程序

在 ServiceStack V3 中,您可以注册一个 GlobalRequestFilter,它将请求 DTO 存储在 IRequestContext.Items 字典中,稍后您可以从请求上下文中获取该字典。
