README

chervand/yii2-oauth2-server is a Yii 2.0 PHP Framework integration of thephpleague/oauth2-server library which implements a standards compliant OAuth 2.0 Server for PHP. It supports all of the grants defined in the specification with usage of JWT Bearer tokens.

chervand/yii2-oauth2-server additionally provides MAC tokens support, which is not supported by the original library, because MAC tokens specification is currently in draft and it was not updated since 2014, so it's a pretty experimental feature.

It also includes tokens revocation implementation based on RFC7009.

Installation

Applying DB migrations

./yii migrate --migrationPath="@vendor/chervand/yii2-oauth2-server/migrations"

Generating public and private keys

See OAuth 2.0 Server installation page.

Integrating with your users

To integrate OAuth 2.0 server with your users DB, you should implement League\OAuth2\Server\Repositories\UserRepositoryInterface for a user component's identityClass which should be extended from chervand\yii2\oauth2\server\models\AccessToken. League\OAuth2\Server\Repositories\UserRepositoryInterface::getUserEntityByUserCredentials() should return your user model instance implementing League\OAuth2\Server\Entities\UserEntityInterface or null. You may additionally add a foreign key for the auth__access_token.user_id column referencing your users table. You mau also override getRateLimit() to provider yii\filters\RateLimitInterface with required values.

<?php 
/** 
 * config/main.php 
 */
return [
    // ...
    'components' => [
        // ...
        'user' => [
            'identityClass' => 'app\components\Identity',
            // ...
        ],
        // ...
    ],
    // ...
];

Configuring the authorization server

Module configuration:

<?php 
/** 
 * config/main.php 
 */
return [
    // ...
    'bootstrap' => [
        'oauth2',
        // ...
    ],
    'modules' => [
        'oauth2' => [
            'class' => \chervand\yii2\oauth2\server\Module::class,
            'privateKey' => __DIR__ . '/../private.key',
            'publicKey' => __DIR__ . '/../public.key',
            'cache' => [
                \League\OAuth2\Server\Repositories\AccessTokenRepositoryInterface::class => [
                    'cacheDuration' => 3600,
                    'cacheDependency' => new \yii\caching\FileDependency(['fileName' => 'example.txt']),
                ],
                \League\OAuth2\Server\Repositories\RefreshTokenRepositoryInterface::class => [
                    'cacheDuration' => 3600,
                    'cacheDependency' => new \yii\caching\FileDependency(['fileName' => 'example.txt']),
                ],
            ],
            'enableGrantTypes' => function (\chervand\yii2\oauth2\server\Module &$module) {
                $server = $module->authorizationServer;
                $server->enableGrantType(new \League\OAuth2\Server\Grant\ImplicitGrant(
                    new \DateInterval('PT1H')
                ));
                $server->enableGrantType(new \League\OAuth2\Server\Grant\PasswordGrant(
                    $module->userRepository,
                    $module->refreshTokenRepository
                ));
                $server->enableGrantType(new \League\OAuth2\Server\Grant\ClientCredentialsGrant());
                $server->enableGrantType(new \League\OAuth2\Server\Grant\RefreshTokenGrant(
                    $module->refreshTokenRepository
                ));
                $server->enableGrantType(new \chervand\yii2\oauth2\server\components\Grant\RevokeGrant(
                    $module->refreshTokenRepository,
                    $module->publicKey
                ));
            },
        ],
        // ...
    ],
    // ...
];

Configuring the resource server

Controller's behaviors configuration:

<?php

class ActiveController extends \yii\rest\ActiveController
{
    public function behaviors()
    {
        $behaviors = parent::behaviors();

        unset($behaviors['authenticator']);
        unset($behaviors['rateLimiter']);

        /** @var \chervand\yii2\oauth2\server\Module $auth */
        $auth = \Yii::$app->getModule('oauth2');

        $behaviors['authenticator'] = [
            'class' => \yii\filters\auth\CompositeAuth::class,
            'authMethods' => [
                [
                    'class' => \chervand\yii2\oauth2\server\components\AuthMethods\HttpMacAuth::class,
                    'publicKey' => $auth->publicKey,
                    'cache' => $auth->cache,
                ],
                [
                    'class' => \chervand\yii2\oauth2\server\components\AuthMethods\HttpBearerAuth::class,
                    'publicKey' => $auth->publicKey,
                    'cache' => $auth->cache,
                ],
            ]
        ];

        $behaviors['rateLimiter'] = [
            'class' => \yii\filters\RateLimiter::class,
        ];

        return $behaviors;
    }

}
