ServiceStack - how to disable default exception logging

Question

In line with the ServiceStack documentation, we have a global service exception handler. The docs say that this handler should log the exception then call DtoUtils.HandleE

Answer 1

I hope the following code solves your problem.

based on the documentation New API, Custom Hooks, ServiceRunner

and Fine grain error handling using the New API's ServiceRunner

in AppHost.Configure

   LogManager.LogFactory = new ServiceStack.Logging.Support.Logging.ConsoleLogFactory();   

then in AppHost class

         public override IServiceRunner CreateServiceRunner(ActionContext      actionContext)
          {
               return new MyServiceRunner(this, actionContext);
            }  

in the ServiceRunner class

       public class MyServiceRunner : ServiceRunner
       {

            public override object HandleException(IRequestContext requestContext, T request, Exception ex)
              {
                  if ( isYourCondition ) 
                  {
                        ResponseStatus rs = new ResponseStatus("error1", "your_message");
                        // optionally you can add custom response errors
                             rs.Errors = new List();
                             rs.Errors.Add(new ResponseError());
                             rs.Errors[0].ErrorCode = "more details 2";

                            // create an ErrorResponse with the ResponseStatus as parameter
                            var errorResponse = DtoUtils.CreateErrorResponse(request, ex, rs);
                             // log the error
                             Log.Error("your_message", ex);
                             return errorResponse;

                   }
                   else
                        return base.HandleException(requestContext, request, ex);
               }

            }

if you return the base.HandleException, it calls internally the DtoUtils.HandleException. You will see in console, one log error only.

In client, if you handle the WebServiceException for custom errors.

            catch (WebServiceException err)
            {
                if ( err.ResponseStatus.Errors != null)
               { // do something with err.ResponseStatus.Errors[0].ErrorCode; 
               }
            }
