Php 未在YII2中加载Css

我在YII2中实现了漂亮的url，在实现之前一切都很好，但现在加载了我的应用程序的样式。我能帮忙吗

我的manin.php

'urlManager' => [
        'class' => 'yii\web\UrlManager',
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
            '<alias:index|login|logout|contact|about|signup|request-password-reset|reset-password>' => 'site/<alias>',
            '<alias:index|create|confirm|confirmation|update|delete>' => 'user/<alias>',
        ],
    ],

'urlManager'=>[
'class'=>'yii\web\UrlManager'，
“enablePrettyUrl”=>true，
'showScriptName'=>false，
“规则”=>[
''=>'站点/'，
''=>'用户/'，
],
],

Request.php

<?php
namespace common\components;
class Request extends \yii\web\Request {
    public $web;
    public $adminUrl;

    public function getBaseUrl(){
        return str_replace($this->web, "", parent::getBaseUrl()) . $this->adminUrl;
    }


/*
    If you don't have this function, the admin site will 404 if you leave off
    the trailing slash.

    E.g.:

    Wouldn't work:
    site.com/admin

    Would work:
    site.com/admin/

    Using this function, both will work.
*/
public function resolvePathInfo(){
    if($this->getUrl() === $this->adminUrl){
        return "";
        }else{
            return parent::resolvePathInfo();
        }
    }
}

以确保应在配置文件中添加以下行..`
