How to handle unergistered API Paramers?

[EvgenyK (Evgeny Karpov)]

Hi,

You can set server.SendExceptionsAs500 to False.

In this case, you will receive exception message

---

if you like to customize this error, you can

• create and use your own descendant of TROHttpApiDispatcher. Put try/except to Process method like

procedure TMyHttpApiDispatcher.Process(aTransport: IROHTTPTransport; aRequest: IROHTTPRequest;
  aResponse: IROHTTPResponse; aRequestData, aResponseData: TStream);
begin
  try
     inherited;
  except
     // <<<<<< customize the response? i.e. aResponse/aResponseData
  end;
end;

• customize the response in server.OnCustomResponseEvent event. You can use it similar to v2 as in Delphi DA REST server versioning with code-first server thread
