Custom exception handling in ServiceStack REST service

Question

I have a ServiceStack REST service and I need to implement custom error handling. I\'ve been able to customize service errors by setting AppHostBase.ServiceExceptionHandler

Answer 1

I made improvements to @mythz' answer.

public override void Configure(Container container) {
    //Handle Exceptions occurring in Services:

    this.ServiceExceptionHandlers.Add((httpReq, request, exception) = > {
        //log your exceptions here
        ...
        //call default exception handler or prepare your own custom response
        return DtoUtils.CreateErrorResponse(request, exception);
    });

    //Handle Unhandled Exceptions occurring outside of Services
    //E.g. Exceptions during Request binding or in filters:
    this.UncaughtExceptionHandlers.Add((req, res, operationName, ex) = > {
        res.Write("Error: {0}: {1}".Fmt(ex.GetType().Name, ex.Message));

#if !DEBUG
        var message = "An unexpected error occurred."; // Because we don't want to expose our internal information to the outside world.
#else
        var message = ex.Message;
#endif

        res.WriteErrorToResponse(req, req.ContentType, operationName, message, ex, ex.ToStatusCode()); // Because we don't want to return a 200 status code on an unhandled exception.
    });
}
