新手等待大神中......

controller方向：

class SiteController extends Controller
{
    public function actions()
    {
        return [
            'auth' => [
                'class' => 'yii\authclient\AuthAction',
                'successCallback' => [$this, 'successCallback'],
            ],
        ]
    }

    public function successCallback($client)
    {
        $attributes = $client->getUserAttributes();
        // user login or signup comes here
    }
}

这里还需要添加什么东西吗？有句话 // user login or signup comes here，是把

public function actionLogin()
{
        $this->title = '用户登陆'.' - '.Yii::$app->name;
        $this->description = '';
        $this->canonical = Yii::$app->params['domain'].'login';

        if (!\Yii::$app->user->isGuest) {
            return $this->goHome();
        }
        $next = Yii::$app->request->get('next');
        $model = new LoginForm();
        if ($model->load(Yii::$app->request->post()) && $model->login()) {
            if(isset($next)) return $this->redirect($next);
            return $this->goHome();
        } else {
            return $this->render('login', [
                'model' => $model,
            ]);
        }
    }，

加到里面？
