Symfony 2 kpn snappy generate pdf with output meets security area - php

Question

I`m using Symfony2 kpn snappy bundle to generate pdfs. I want to generate PDF from an html page with css. I found a solution, but it has a problem with :
$pageUrl = $this->generateUrl('accounts_management_generate_pdf_markup',
array('invoice' => $invoiceData), true); // use absolute path!
return new \Symfony\Component\HttpFoundation\Response(
$this->get('knp_snappy.pdf')->getOutput($pageUrl), 200, array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="file.pdf"'
)
);
The problem is that the pageUrl accounts_management_generate_pdf_markup is behind a security area and cannot be accessed without authentication. The generated file is just the login page, to which this path accounts_management_generate_pdf_markup redirects if not logged.
My questions are:
Is there any way to pass to snappy authentication credentials?
Is there another way using snappy bundle to generate the pdf using styles(css)

You can add the session cookie as an argument to the getOutput function:
$pageUrl = $this->generateUrl('route', array('id' => $id), true);
$session = $this->get('session');
$session->save();
session_write_close();
return new Response(
$this->get('knp_snappy.pdf')->getOutput($pageUrl, array('cookie' => array($session->getName() => $session->getId()))),
200,
array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="file.pdf"'
)
);
