How to use this extension with official Yii2 AuthClient ?

[ahmadfadlydziljalal]

I have 2 apps:

• Yii2 server (wtih this exxtension itself)
• Yii2 client (With https://github.com/yiisoft/yii2-authclient )

Everything is looked good in every step at Yii2 server side:

 'components' => [
        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                '<alias:\w+>' => 'site/<alias>',
                'POST oauth2/<action:\w+>' => 'oauth2/rest/<action>',
            ]
        ],
],
 'modules' => [
        'oauth2' => [
           'class' => 'filsh\yii2\oauth2server\Module',
           'components' => [
              'request' => function () {
                 return \filsh\yii2\oauth2server\Request::createFromGlobals();
              },
              'response' => [
                 'class' => \filsh\yii2\oauth2server\Response::class,
              ],
           ],
            'tokenParamName' => 'accessToken',
            'tokenAccessLifetime' => 3600 * 24,
            'storageMap' => [
                'user_credentials' => 'app\models\User',
            ],
            'grantTypes' => [
                'user_credentials' => [
                    'class' => 'OAuth2\GrantType\UserCredentials',
                ],
                'authorization_code' => [
                   'class' => 'OAuth2\GrantType\AuthorizationCode'
                ],
                'refresh_token' => [
                    'class' => 'OAuth2\GrantType\RefreshToken',
                    //'always_issue_new_refresh_token' => true
                ]
            ],
            'options' => [
                'allow_implicit' => true
            ]
        ],
  ....

But the problem is, when client side successfully login, why userAttributes is null ?
In Yii2 client side, I set the SiteController like this:

 /**
     * {@inheritdoc}
     */
    public function actions()
    {
        return [
            'error' => [
                'class' => 'yii\web\ErrorAction',
            ],
            'captcha' => [
                'class' => 'yii\captcha\CaptchaAction',
                'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
            ],
            'auth' => [
                'class' => 'yii\authclient\AuthAction',
                'successCallback' => [$this, 'onAuthSuccess'],
            ],
        ];
    }

    public function onAuthSuccess($client)
    {
        (new AuthHandler($client))->handle();
    }

Then, in AuthHandler:

<?php

namespace app\components;

use app\models\Auth;
use app\models\User;
use Exception;
use Yii;
use yii\authclient\ClientInterface;
use yii\helpers\ArrayHelper;
use yii\helpers\Html;
use yii\helpers\StringHelper;
use yii\helpers\VarDumper;

/**
 * AuthHandler handles successful authentication via Yii auth component
 */
class AuthHandler
{
    /**
     * @var ClientInterface
     */
    private ClientInterface $client;

    public function __construct(ClientInterface $client)
    {
        $this->client = $client;
    }

    /**
     * @return void
     * @throws \yii\base\Exception
     * @throws \yii\db\Exception
     * @throws Exception
     */
    public function handle()
    {
       
        $attributes = $this->client->getUserAttributes();

        /*
         * for debugging
         * die(Html::tag('pre', VarDumper::dumpAsString($attributes)));
         * */

        $email = ArrayHelper::getValue($attributes, 'email');
        $id = ArrayHelper::getValue($attributes, 'id');
        $nickname = str_replace(" ", "-", ArrayHelper::getValue($attributes, 'name'));

        /* @var Auth $auth */
        $auth = Auth::find()->where([
            'source' => $this->client->getId(),
            'source_id' => $id,
        ])->one();

        if (Yii::$app->user->isGuest) {

            if ($auth) { // login

                $user = $auth->user;
                $this->updateUserInfo($user);
                Yii::$app->user->login($user, Yii::$app->params['user.rememberMeDuration']);
                Yii::$app->getSession()->setFlash(
                    'success',
                    'Login by ' . ucfirst($this->client->getId()) . ' Welcome! '
                );
            } else { // signup

                if ($email !== null && User::find()->where(['email' => $email])->exists()) {

                    Yii::$app->getSession()->setFlash('error', [
                        Yii::t('app', "User with the same email as in {client} account already exists but isn't linked to it. Login using email first to link it.", ['client' => $this->client->getTitle()]),
                    ]);
                } else {

                    $password = Yii::$app->security->generateRandomString(Yii::$app->params['user.passwordMinLength']);
                    $user = new User([
                        'username' => $nickname,
                        //'github' => $nickname,
                        'email' => $email,
                        'password' => $password,
                    ]);
                    $user->generateAuthKey();
                    $user->generatePasswordResetToken();

                    $transaction = User::getDb()->beginTransaction();

                    if ($user->save()) {

                        $auth = new Auth([
                            'user_id' => $user->id,
                            'source' => $this->client->getId(),
                            'source_id' => (string)$id,
                        ]);

                        if ($auth->save()) {

                            $transaction->commit();

                            Yii::$app->getSession()->setFlash(
                                'success',

                            );

                        }

                $auth = new Auth([

                if ($auth->save()) {

                    $user = $auth->user;
                    $this->updateUserInfo($user);
                    Yii::$app->getSession()->setFlash('success', [

                $user->save();
            }
        }
    }
}

Here is the config that I used in Yii2 client side:

<?php

namespace app\components;

use yii\authclient\OAuth2;

class MyAuthClient extends OAuth2
{

    protected function defaultName()
    {
        return 'my_auth_client';
    }

    protected function defaultTitle()
    {
        return 'My Auth Client';
    }

    protected function initUserAttributes()
    {
        return $this->api('userinfo', 'GET');
    }
}

 'components' => [
        'authClientCollection' => [
            'class' => 'yii\authclient\Collection',
            'clients' => [
                'myauth' => [
                    'class' => '\app\components\MyAuthClient',
                    'clientId' => 'testclient',
                    'clientSecret' => 'testpass',
                    'authUrl' => 'http://10.60.36.60:8080/authorize',
                    'tokenUrl' => 'http://10.60.36.60:8080/oauth2/token',
                    'apiBaseUrl' => 'http://10.60.36.60:8080/apis/oauth2/v1'
                ],

            ],
        ],

Maybe we need, how to implement the OpenID ?
