yii2 GoogleOAuth成功重定向到404

Question

I'm using yii2-authclient for user login

 'authClientCollection' => [
      'class' => 'yii\authclient\Collection',
      'clients' => [
          'google' => [
              'class' => 'yii\authclient\clients\GoogleOAuth',
              'clientId' => '*********',
              'clientSecret' => '*********',
              'returnUrl'=>'http://mywebsite/frontend/web/index.php?r=site/auth?authclient=google',

          ],

and in the controller 'auth' => [ 'class' => 'yii\authclient\AuthAction', 'successCallback' => [$this, 'successCallback'],

but after redirect from google to http://mywebsite/frontend/web/index.php?r=site/auth?authclient=google' it shows error Not Found (#404)
