Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require gbksoft/yii2-tokens

or add

"gbksoft/yii2-tokens": "~1.0.0"

to the require section of your composer.json file.

Usage

Module configurations:

...
    'modules' => [
        'tokens' => [
            'class' => 'gbksoft\modules\tokens\Module',
            'userClass' => common\models\User::class,
            'urlRulePrefix' => 'v1/',
            'on beforeControllerBehavior' => function($event) {
                // Update behaviors on module controller "User"
                $event->data = common\overrides\rest\ActiveController::getDefaultBehaviors();
            },
        ],
    ],
...

Change table name for relations to users table. Console application event for change {{%user}} table name in module migrations example:

    'on beforeUserTokenMigrateUp' => function($event) {
        // $event->sender is Migration class
        // $event->sender->usersTableName default value is "{{%user}}"
        $event->sender->usersTableName = '{{%users}}';
    }

Use controllerMap in console config:

    'controllerMap' => [
        'migrate' => [
            'class' => 'console\controllers\MigrateController',
            'migrationLookup' => [
                '@console/migrations',
                '@vendor/gbksoft/yii2-tokens/migrations',
            ]
        ]
    ],

In IdentityInterface (User model)

use yii\web\UnauthorizedHttpException;
use gbksoft\modules\tokens\models\UserToken;

...

class User extends ActiveRecord implements IdentityInterface
{
    ...

    public $userToken;

    /**
     * @inheritdoc
     */
    public static function findIdentityByAccessToken($token, $type = null)
    {
        /** @var $userToken \common\models\UserToken */
        $userToken = UserToken::find()
            ->andWhere(['=', 'token', $token])
            ->one();
        
        if (!$userToken) {
            throw new UnauthorizedHttpException('Bad token');
        }
        
        if (!$userToken->user) {
            throw new UnauthorizedHttpException('User not found');
        }
        
        if ($userToken->user->status == self::STATUS_DELETED) {
            throw new UnauthorizedHttpException('This user has deleted');
        }
        
        if (!$userToken->matchIp(Yii::$app->getRequest()->userIP)) {
            throw new UnauthorizedHttpException('Differed user token IP-s');
        }
        
        if ($userToken->expired()) {
            throw new UnauthorizedHttpException('User token is expired');
        }
        
        $user = $userToken->getUser()->one();
        $user->userToken = $userToken;
        
        return $user;
    }

    ...
}
