yii2登录页面重定向循环，取消状态

Question

After spending so many days, am trying to get some help from experts. I am stuck with login redirection in my yii2 application only in chrome browser,

This is my controller class,

    class InvitationsController extends Controller
{
    public function beforeAction($action)
    {   $array=array('index','imageupload','template','category','subcategory','slug','chooseanotherdesign');
        if(!in_array($action->id, $array))
           {
                if (\Yii::$app->getUser()->isGuest &&
                    \Yii::$app->getRequest()->url !== Url::to(\Yii::$app->getUser()->loginUrl)
                ) {
                    \Yii::$app->getResponse()->redirect(\Yii::$app->getUser()->loginUrl,FALSE);
                }
           }
                return parent::beforeAction($action);
    }
    public function actionGenerateevent(){
        $redirectUrl="";
                if(Yii::$app->request->post()){
                    unset(Yii::$app->session['copyinvitation']);
                    unset(Yii::$app->session['eventform']);
                    Yii::$app->session['eventform']=Yii::$app->request->post();
                }
                if (!Yii::$app->user->isGuest)
                {
                        $eventid=$this->invitation->savecontinue(Yii::$app->session['eventform']);
                        $eventdata=$this->invitation->getEventById($eventid);
                        $refurl=Yii::$app->session['eventform']['refererurl'];
                        $aa['Events']=$eventdata;
                        $aa['refererurl']=$refurl;
                        Yii::$app->session['eventform']=$aa;
                        $redirectUrl = Yii::$app->urlManager->createAbsoluteUrl(['invitations/event/'.$eventdata['event_token']]);
                        return $this->redirect($redirectUrl);
                }


    }
}

My workflow step1: submitting formdata to controller xx-action step2: If user login it will proceed further action Else am trying to store the values in session then redirecting the page to login

step 3: after successful login am return back to same xx-action

This workflow is working fine in firefox but chrome it's making infinitive loop its not going through the login page. Please refer am attached the screenshot

Please help me to solve this issue.

I can't infere how are you calling your actionGenerateevent() but you seems to have an error there:

$redirectUrl=""; //empty
...
return $this->redirect($redirectUrl); //still empty

Since you are not setting your $redirectUrl, your redirect is redirecting you to the current (same) url again and again, causing the loop.

This is the function used by redirectUrl() method: Url::to(). Its docs says:

an empty string: the currently requested URL will be returned;
