README

This is a package to integrate mixer authentication with the OAuth2 client library by The League of Extraordinary Packages.

Installation

To install, use composer:

composer require morgann/oauth2-mixer

Usage

Usage is the same as the league's OAuth client, using \Morgann\OAuth2\Client\Mixer\Provider\Mixer as the provider. For example:

$provider = new \Morgann\OAuth2\Client\Mixer\Provider\Mixer([
    'clientId' => "YOUR_CLIENT_ID",
    'clientSecret' => "YOUR_CLIENT_SECRET",
    'redirectUri' => "http://your-redirect-uri"
]);

You can also optionally add a scopes key to the array passed to the constructor. The available scopes are documented on the Mixer API Documentation.

Note: The provider uses the "user:details:self" scope by default. If you pass other scopes, and want the ->getResourceOwner() method to work, you will need to ensure the "user:details:self" scope is used.

if (isset($_GET['code']) && $_GET['code']) {
    $token = $this->provider->getAccessToken("authorization_code", [
        'code' => $_GET['code']
    ]);

    // Returns an instance of Morgann\OAuth2\Client\Mixer\Entity\MixerUser
    $user = $this->provider->getResourceOwner($token);
    
    $user->getId();
    $user->getAvatar()
    $user->getBio();
    $user->getCreatedAt();
    $user->getEmail();
    $user->getExperience();
    $user->getLevel();
    $user->getName();

Symfony Framework Integration

Full documentation for adding providers is available at KnpUOAuth2ClientBundle.

Step 1 - Configure provider

Add Mixer in list of providers

# config/packages/knpu_oauth2_client.yaml
knpu_oauth2_client:
  clients:
    # ...
    mixer:
      type: generic
      provider_class: Morgann\OAuth2\Client\Mixer\Provider\Mixer
      client_id: '%env(resolve:OAUTH_MIXER_ID)%'
      client_secret: '%env(resolve:OAUTH_MIXER_SECRET)%'
      redirect_route: connect_mixer_check
      redirect_params: {}

Add your credentials in env

OAUTH_MIXER_ID=XXXXXXXXXXX
OAUTH_MIXER_SECRET=XXXXXXXXXXX

Step 2 - Add the client controller

Create the Mixer authenticator controller

<?php

namespace App\Controller\Authenticator;

use KnpU\OAuth2ClientBundle\Client\ClientRegistry;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;

class MixerController extends AbstractController
{
    /**
     * Connect
     * @Route("/connect/mixer", name="connect_mixer")
     * @param \KnpU\OAuth2ClientBundle\Client\ClientRegistry $clientRegistry
     * @return \Symfony\Component\HttpFoundation\RedirectResponse
     */
    public function connectAction(ClientRegistry $clientRegistry)
    {
        return $clientRegistry
            ->getClient('mixer')
            ->redirect();
    }

    /**
     * Connect check
     * @Route("/connect/mixer/check", name="connect_mixer_check")
     * @param \Symfony\Component\HttpFoundation\Request $request
     * @return \Symfony\Component\HttpFoundation\JsonResponse|\Symfony\Component\HttpFoundation\RedirectResponse
     */
    public function connectCheckAction(Request $request)
    {
        if (!$this->getUser()) {
            return new JsonResponse(array('status' => false, 'message' => "User not found!"));
        } else {
            return $this->redirectToRoute('home');
        }
    }
}

Step 3 - Add the guard authenticator

Now create the Mixer authenticator guard :

<?php

namespace App\Security\Authenticator;

use App\Entity\UserEntity;
use Doctrine\ORM\EntityManagerInterface;
use KnpU\OAuth2ClientBundle\Client\ClientRegistry;
use KnpU\OAuth2ClientBundle\Security\Authenticator\SocialAuthenticator;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;

class MixerAuthenticator extends SocialAuthenticator
{
    private $clientRegistry;
    private $em;
    private $router;
    private $encoder;

    /**
     * Constructor
     * @param \KnpU\OAuth2ClientBundle\Client\ClientRegistry $clientRegistry
     * @param \Doctrine\ORM\EntityManagerInterface $em
     * @param \Symfony\Component\Routing\RouterInterface $router
     * @param \Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface $encoder
     */
    public function __construct(ClientRegistry $clientRegistry, EntityManagerInterface $em, RouterInterface $router, UserPasswordEncoderInterface $encoder)
    {
        $this->clientRegistry = $clientRegistry;
        $this->em = $em;
        $this->router = $router;
        $this->encoder = $encoder;
    }

    /**
     * Supports
     * @param \Symfony\Component\HttpFoundation\Request $request
     * @return \Symfony\Component\HttpFoundation\Request $request
     */
    public function supports(Request $request)
    {
        return $request->getPathInfo() == '/connect/mixer/check' && $request->isMethod('GET');
    }

    /**
     * Get credentials
     * @param \Symfony\Component\HttpFoundation\Request $request
     * @return \League\OAuth2\Client\Token\AccessToken
     */
    public function getCredentials(Request $request)
    {
        return $this->fetchAccessToken($this->getMixerClient());
    }

    /**
     * Get user
     * @param array $credentials
     * @param \Symfony\Component\Security\Core\User\UserProviderInterface $userProvider
     * @return \App\Entity\UserEntity $user
     * @throws \Exception
     */
    public function getUser($credentials, UserProviderInterface $userProvider)
    {
        $mixerUser = $this->getMixerClient()
            ->fetchUserFromToken($credentials);

        $email = $mixerUser->getEmail();

        $user = $this->em->getRepository('App:UserEntity')
            ->findOneBy(['email' => $email]);
        if (!$user) {
            $user = new UserEntity();
            $user->setEmail($mixerUser->getEmail());
            $user->setFullname($mixerUser->getName());
            $user->setPassword(
                $this->encoder->encodePassword(
                    $user,
                    base64_encode(random_bytes(10))
                )
            );
            $this->em->persist($user);
            $this->em->flush();
        }

        return $user;
    }

    /**
     * Get Mixer Client
     * @return \KnpU\OAuth2ClientBundle\Client\OAuth2Client
     */
    private function getMixerClient()
    {
        return $this->clientRegistry
            ->getClient('mixer');
    }

    /**
     * Returns a response that directs the user to authenticate
     * @param Request $request
     * @param \Symfony\Component\Security\Core\Exception\AuthenticationException $authException
     * @return \Symfony\Component\HttpFoundation\Response
     */
    public function start(Request $request, \Symfony\Component\Security\Core\Exception\AuthenticationException $authException = null)
    {
        return new RedirectResponse('/login');
    }

    /**
     * Called when authentication executed but failed
     * @param Request $request
     * @param \Symfony\Component\Security\Core\Exception\AuthenticationException $exception
     * @return \Symfony\Component\HttpFoundation\Response|null
     *
     * @todo Implement onAuthenticationFailure() method.
     */
    public function onAuthenticationFailure(Request $request, \Symfony\Component\Security\Core\Exception\AuthenticationException $exception)
    {
    }

    /**
     * Called when authentication executed and was successful
     * @param Request $request
     * @param \Symfony\Component\Security\Core\Authentication\Token\TokenInterface $token
     * @param string $providerKey
     * @return void
     *
     * @todo Implement onAuthenticationSuccess() method.
     */
    public function onAuthenticationSuccess(Request $request, \Symfony\Component\Security\Core\Authentication\Token\TokenInterface $token, $providerKey)
    {
    }
}

Now you can register your authenticator in security configuration file :

security:
    # ...
    firewalls:
        # ...
        main:
            # ...
            guard:
                authenticators:
                    - App\Security\Authenticator\MixerAuthenticator

Laravel Framework Integration

This package includes Laravel framework integration if you need it. Simply require it as normal in your Laravel application, and add the Service Provider Morgann\OAuth2\Client\Mixer\FrameworkIntegration\Laravel\MixerOAuth2ServiceProvider to your config/app.php.

Next, publish the configuration with php artisan vendor:publish, and fill out your client details in the config/morgann/oauth2-mixer/config.php file that is generated.

This will register bindings in the IoC container for the Mixer Provider, so you can simply typehint the \Morgann\OAuth2\Client\Mixer\Provider\Mixer in your controller methods and it will yield a properly configured instance. ) for details.

Testing

Tests can be run with:

composer phpunit
