How to get the current logged User in a service

Question

In Symfony 2.8/3.0, with our fancy new security components, how do I get the currently logged User (i.e. FOSUser) object in a service without

Answer 1

Symfony does this in Symfony\Bundle\FrameworkBundle\ControllerControllerTrait

protected function getUser()
{
    if (!$this->container->has('security.token_storage')) {
        throw new \LogicException('The SecurityBundle is not registered in your application.');
    }

    if (null === $token = $this->container->get('security.token_storage')->getToken()) {
        return;
    }

    if (!is_object($user = $token->getUser())) {
        // e.g. anonymous authentication
        return;
    }

    return $user;
}

So if you simply inject and replace security.token_storage, you're good to go.
