Change HTTP status code as needed

Remoting SDK

Hi,
would it be possible to programmatically change HTTP status code for a HttpApi method?

Even if it would be possible to change raising an Exception, I’d also need to return my object using a status code different from the default defined by code annotation.

Thank you very much,
Giovanni

It woud be nice to raise an exception

EROHttpApiException(myHttpCode: integer,  myObject : TROComplexType)

where myObject could be JSon serialized to create a message returned to client with myHttpCode status.

How can I simply serialize using RoSdk?

Thank you

Giovanni,

my apologies for the delay; unfortunately part of our team if off today and tomorrow, for local holidays, so it might be until Wednesday to have an answer for this…

Thank you, Marc.

meanwhile I created a TROComplexType helper class using TROJSONMessage but, I think, there may be a better solution

Hi,

you can use TROHttpApiResult:

  [ServiceMethod]
  [ROCustom('HttpApiPath', 'test')]
  function TestMethod(): Binary;
...
function TMyService.TestMethod(): Binary;
begin
  Result := TROHttpApiResult.Create(HTTP_200_code, id_ContentType_image_jpeg,'',false);
  Result.LoadFromFile(..image file location here..);
end;

see more info here

Thank you Evgeny,

but I’d like to use a TROComplex as HTTPApi result instead of Binary and, for error conditions, raising an Exception using the TROComplex class, too.

The solution I found seems to work for me.

Thank you very much.

Hi,

you can put your json string to stream and return it …
another solution - use the OnCustomResponseEvent event as described at the OnCustomResponseEvent in a ROSDK Server topic.

here you can manipulate with request/response as you want …

Ok, thank you again.

Hello,
would it be possible to raise a EROHttpApiException changing Content-Type header text/plain to application/json ?

Thank you very much,
Giovanni

Hi,

The EROHttpApiException exception is written with text/plain; charset=utf-8 content type.
if you want to return error with other content type, you can use Using OnCustomResponseEvent in a ROSDK Server or return it via TROHttpApiResult.
