Symfony2 session用法实例分析,symfony2实例分析

本文实例分析了Symfony2 session用法。分享给大家供大家参考,具体如下:

Symfony自带有session的方法,以前老版本2.2及以前的session用法是

$session = $this->getRequest()->getSession();
$session->set('foo', 'bar');
$foobar = $session->get('foobar');

Copy after login

后来Symfony2.3开始$this->getRequest()方法被废弃,session的使用方法就变成了

use Symfony\Component\HttpFoundation\Request;
public function indexAction(Request $request)
{
  $session = $request->getSession();
  // store an attribute for reuse during a later user request
  $session->set('foo', 'bar');
  // get the attribute set by another controller in another request
  $foobar = $session->get('foobar');
  // use a default value if the attribute doesn't exist
  $filters = $session->get('filters', array());
}

Copy after login
