Yii2 制作一个404页面

我是通过模块的方式添加的。

1.添加模块:

'site' => [
    'class' => '\fecshop\app\appfront\modules\Site\Module',
    
  ],

2.新建controller方法:

<?php
namespace fecshop\app\appfront\modules\Site\controllers;
use Yii;
use fec\helpers\CModule;
use fecshop\app\appfront\modules\AppfrontController;
class HelperController extends AppfrontController
{
    public function actions()
    {
        return [
            'error' => [
                'class' => 'yii\web\ErrorAction',
            ],
            'captcha' => [
                'class' => 'yii\captcha\CaptchaAction',
                'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
            ],
        ];
    }



}

3.新建view方法

<?php

/* @var $this yii\web\View */
/* @var $name string */
/* @var $message string */
/* @var $exception Exception */

use yii\helpers\Html;

$this->title = $name;
?>
<div class="site-error">

    <h1><?= Html::encode($this->title) ?></h1>

    <div class="alert alert-danger">
        <?= nl2br(Html::encode($message)) ?>
    </div>

    <p>
        The above error occurred while the Web server was processing your request.
    </p>
    <p>
        Please contact us if you think this is a server error. Thank you.
    </p>

</div>

4.设置:(config)

'errorHandler' => [
      'errorAction' => 'site/helper/error',
    ],

这样就添加成功了。
