Question

Yii

In beforeAction , the NotFoundHttpException is displayed as an error, not a 404 page. Why?
How to display normally?

Answer 1

Are you sure you are throwing exceptions? The code below works great and returns 404

<?php

namespace backend\controllers;

use Yii;
use yii\web\Controller;
use yii\web\NotFoundHttpException;

class SiteController extends Controller
{

    public function beforeAction($action)
    {
        throw new NotFoundHttpException();
    }
