Symfony2-重新登录后重定向用户，如果由于会话过期而注销？

Question

In Symfony 2.8, if user's session expires, he'll be logged out and redirected to login page after he makes new request.
After user logs in again, how can I redirect the user back to the page he wanted to open before he was redirected? Or at least to the last page he opened (page, on which session expired)?

Answer 1

You could let the login action check or there was a referer, and update the security target path. Make sure that referrer is safe before you do this ;-)

$yourReferer = $request->headers->get('referer');
$this->container->get('session')->set('_security.main.target_path', $yourReferer);

The login mechanism will use that target_path after a successful login attempt.

Answer 2

Using the header to get the referrer (ie $request->headers->get('referer') ) will not work in this case because it will always return the login link.
