ServiceNotFoundException in Container.php line 268: You have requested a non-existent service "security.context".

Answer 1

The security.context service was deprecated in the 2.6 and split into two new services: security.authorization_checker and security.token_storage.

Some different usage from the prior version of the framework:

// Symfony 2.5
$user = $this->get('security.context')->getToken()->getUser();
// Symfony 2.6
$user = $this->get('security.token_storage')->getToken()->getUser();

// Symfony 2.5
if (false === $this->get('security.context')->isGranted('ROLE_ADMIN')) { ... }
// Symfony 2.6
if (false === $this->get('security.authorization_checker')->isGranted('ROLE_ADMIN')) { ... }
