README

With this bundle, you can request an access token on your api (that uses FOSOAuthServerBundle) against a facebook access token. This bundle will check that the facebook access token is valid, and get the fb_id of the user.

For example: you have an iOS app that needs a token to authenticate a user against your api, but you want to only show the Facebook SSO authentication to your user.

Installation

Add the bundle to your AppKernel

class AppKernel extends Kernel
    public function registerBundles()
        {
            $bundles = array(
                ...
                new AdrienBrault\OAuth2FacebookGrantBundle\ABOAuth2FacebookGrantBundle(),

Configure the bundle:

ab_oauth2_facebook_grant:
    user_provider: bundle.facebook_user_provider
    uri: "http://grants.yourapi.com/facebook_access_token"

And implement your bundle.facebook_user_provider like this:

<?php

namespace AdrienBrault\Core\UserBundle\Security;

use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Core\User\UserInterface;

use FSC\Core\UserBundle\Manager\UserManager;

class FacebookUserProvider implements UserProviderInterface
{
    protected $userManager;

    public function __construct(UserManager $userManager)
    {
        $this->userManager = $userManager;
    }

    public function loadUserByUsername($facebookId)
    {
        $userRepository = $this->userManager->getRepository();

        return $userRepository->findOneBy(array(
            'facebookID' => $facebookId,
        ));
    }

    public function refreshUser(UserInterface $user)
    {
        $class = get_class($user);
        if (!$this->supportsClass($class)) {
            throw new UnsupportedUserException(sprintf('Instances of "%s" are not supported.', $class));
        }

        return $this->loadUserByUsername($user->getFacebookID());
    }

    public function supportsClass($class)
    {
        return $this->userManager->supportsClass($class);
    }
}
