Re: Send PDF file using HTTPServer

Take first a look at those extjs samples:
https://github.com/synopse/mORMot/tree/ … tJS%20Grid
https://github.com/synopse/mORMot/tree/ … 0FishFacts

You have a way to return any kind of information from the server, then consume it from extjs.

Re: Send PDF file using HTTPServer

this already implemented
My problem is how to send PDF to the client

function TMyClassDirect.relatorio(): RawJSON;
var
  ExtjsVO        : TExtjsVO;
  ListaRelatorio : TList;
  RelatorioVO    : TRelatorioVO;
  FS             : TFileStream;
begin
  ExtjsVO         := TExtjsVO.Create;
  ListaRelatorio  := TList.Create();
  RelatorioVO     := TRelatorioVO.Create;
  try
    FS := TFileStream.Create('\pdf\pedido.pdf', fmCreate);
    RelatorioVO.LISTA := FS;
    ListaRelatorio.Add(RelatorioVO);
    ExtjsVO.success := true;
    ExtjsVO.rows    := ListaRelatorio;
    ExtjsVO.total   := Registros;
  except
    ExtjsVO.success := False;
    ExtjsVO.rows    := ListaRelatorio;
    ExtjsVO.total   := 0;
  end;

  Result := ObjectToJson(ExtjsVO,[]);

  FreeAndNil(ExtjsVO);
  FreeAndNil(ListaRelatorio);
  FreeAndNil(RelatorioVO);
  FreeAndNil(FS);

end;

return:

{"result":[{"success":false,"rows":[],"total":0}]}

Re: Send PDF file using HTTPServer

Transmit the response as a BLOB, using a custom answer type for the interface method.

See http://synopse.info/files/html/Synopse% … #TITLE_405
