User not logged in with AuthClient

Yii 2.0 General Discussions

Hi guys. I am dabbling around with Yii2’s AuthClient and I just can’t seem to login to my app.

Here is my codes:-

frontend\config\main.php


'components' => [

    'user' => [

        'identityClass' => 'common\models\User',

        'enableAutoLogin' => true,

    ],

    'authClientCollection' => [

        'class' => 'yii\authclient\Collection',

        'clients' => [

            'facebook' => [

                'class' => 'yii\authclient\clients\Facebook',

                'clientId' => 'xxx',

                'clientSecret' => 'xxx',

            ],

        ],

    ]

],

frontend\controllers\SiteController.php


class SiteController extends Controller

{

    public $successUrl = 'http://app.dev/index.php';


    /**

     * @inheritdoc

     */

    public function actions()

    {

        return [

            'auth' => [

                'class' => 'yii\authclient\AuthAction',

                'successCallback' => [$this, 'successCallback'],

                'successUrl' => $this->successUrl,

            ],

        ];

    }


    public function successCallback($client)

    {

        if (!$this->action instanceof \yii\authclient\AuthAction) {

            throw new \yii\base\InvalidCallException("successCallback is only meant to be executed by AuthAction!");

        }


        $attributes = $client->getUserAttributes();


        $externalUser = \common\models\User::find()->where(['email' => $attributes['email']])->one();

        

        if ($externalUser->validate())

        {

            if ($externalUser->isRegistered())

            {

                $externalUser->login();

                return $this->action->redirect( Url::toRoute(['private/index'],true) );

            }

            else

            {

                $session = Yii::$app->session;

                $session['attributes'] = $attributes;

                $this->successUrl = \yii\helpers\Url::to(['signup']);

            }

        }

    }

}

I am able to get user’s Facebook attributes and from those information, determine if user exists in my database. print_r on $attributes and $externalUser shows correct user data. It will then redirect to successUrl but Yii::$app->user->getId() suggests that the user is not logged in.

Any pointers on what I am missing here?

Thanks.

You confused the ActiveRecord with user instance, your code should look as follow




    public function successCallback($client)

    {

        if (!$this->action instanceof \yii\authclient\AuthAction) {

            throw new \yii\base\InvalidCallException("successCallback is only meant to be executed by AuthAction!");

        }


        $attributes = $client->getUserAttributes();


        $externalUser = \common\models\User::find()->where(['email' => $attributes['email']])->one();

        //$externalUser is an ActiveRecord not a user instance


        if (!empty($externalUser)) {

            //you found the authenticated user in your local db

            Yii::$app->user->login($externalUser); //here you start the user session

            //save some data in session

            $session = Yii::$app->session;

             //these line is from google+ answer, eventually set in session data from facebook if you need

            $session['user'] = [

                'displayName' => $attributes['displayName'], 

                'avatar'=>$attributes['image']['url']

            ];

        } else {

            $session->destroy(); //just in case destroy the session

            Yii::$app->user->logout(); // and to be sure force a logout

            $this->successUrl = \yii\helpers\Url::to(Yii::$app->getUser()->loginUrl);

        }

    }

}
