Symfony2 custom user checker based on accepted eula

Question

I want to create custom user checker to validate login action against last accepted eula. \' Idea is quite simple, there will be many versions of eula and user can\'

Answer 1

The answer is actually quite obvious. In your custom bundle:

config.yml

parameters:
    security.user_checker.class: Acme\Bundle\UserBundle\Security\UserChecker

Userchecker:

class UserChecker extends BaseUserChecker
{
    /**
     * {@inheritdoc}
     */
    public function checkPreAuth(UserInterface $user)
    {
        //do your custom preauth stuff here
        parent::checkPreAuth($user);
    }
}

Answer 2

Why not attach event listener to the kernel.request event and watch if the current logged user has accepted the latest EULA?

To get the current user you can use something like this:

$securityContext = $this->container->get('security.context');
if (!$securityContext) {
    return;
}

$user = $securityContext->getToken()->getUser();

Answer 3

You can redefine Symfony's user checker service (security.user_checker) in your bundle:

# services.yml
security.user_checker:
    class: MyBundle\Checker\UserChecker
    arguments: [ "@some.service", "%some.param%" ]

Then extend Symfony's UserChecker:

# UserChecker.php

use Symfony\Component\Security\Core\User\UserChecker as BaseUserChecker;

class UserChecker extends BaseUserChecker
{
    public function checkPreAuth(UserInterface $user)
    {
        parent::checkPreAuth($user);

        // your stuff
    }

    public function checkPostAuth(UserInterface $user)
    {
        parent::checkPostAuth($user);

        // your stuff
    }
}

The security.user_checker service gets called in \Symfony\Component\Security\Core\Authentication\Provider\UserAuthenticationProvider::authenticate() during the authentication process
