Yii2设置自定义会话

I want to add costum session and session values query from user table (database)

where I put Yii::$app->session->set('blabla','1234')?

If I put in login controller and user is set auto login (not access login), the session can't set

In your app\components\User component you could just hook to the afterLogin event

example:

namespace \app\components;

Class User extends \yii\web\User{
   public function afterLogin($identity, $cookieBased, $duration){
      parent::afterLogin($identity, $cookieBased, $duration);
      Yii::$app->session->set('blabla','1234')
   }
}
