[Cppcms-users] Creating and downloading reports at run-time

[<ele...@ex...>]

Hi,

This may have an obvious answer but, basically Ive got a PDF report to
generate at runtime when /report function gets dispatched.

Theoretically speaking, the PDF gets created and saved as myreport.pdf,
how do you then send it to the browser?

What if I want to skip the PDF saving to disk, and send it directly out of
a buffer

Do you you just do response().out() << buffer

and set the content type appropriately?

Thanks,
Petr

Too easy.

How do you set the name of the file when returning a buffer? (you know
when the client is shown a dialog to save/open the file)

Is that done with Content-Location header?

No, it is done using Content-Disposition header:

   Content-Disposition: attachment; filename=myfle.pdf
