Returning file from interface based services

Hi,

I hope this one will be easier, I'm using interface based web services and I need to send a PDF file to the client ( testing with google chrome ) I have this code on place :

procedure GetReport( idReport:Integer );
var
  context: TServiceRunningContext;
begin
  context := CurrentServiceContext;

  context.Request.Call.OutHead   := HEADER_CONTENT_TYPE + HTTP_RESP_STATICFILE;
  context.Request.Call.OutBody   := './reports/January.pdf';
  context.Request.Call.OutStatus := 200;
end;

The former code is giving the following answer on the browser :

Server Error 404: Not Found

I don't know if this is the right way to serve files, because the procedure gets executed (already tried with function instead) but the file is not arriving to the browser, I looked at the sample 09 Http Api Web Server but the sample code isn't for interface based web services, may be it is not posible?

Ensure you get the latest 1.18 revision of the source and SAD PDF.
Then please read paragraph 17.7.4.2.3. Custom returned content

Re: Returning file from interface based services

Thank you Arnaud,

If anybody ever needs to do this the working code is as follows :

function TServiceCustomers.GetReport(idReport: Integer): TServiceCustomAnswer;
var
  reportFileName: RawUTF8;
begin
  // some custom logic to locate the right file
  result.Header := HEADER_CONTENT_TYPE + HTTP_RESP_STATICFILE;
  result.Content:= reportFileName;
end;

Regards
