Yii2。进入上一级文件夹 Yii2。进入上一级文件夹(Yii2. Access to h

简单的问题。我用Yii2先进的模板。在apache我DocumentRoot "{$path}/www/yii-application1/frontend/web" 。如何访问/www/yii-application1/uploads为了显示图像的用户？下面的code无法正常工作：

<?php echo Html::img('../../uploads/ring.jpg') ?>

它的工作原理与DocumentRoot "{$path}/www/yii-application1/" 但在这种情况下， index网站的页面看起来像domain.com/frontend/web 。但我只需要domain.com 。

Answer 1:

步骤1

首先在这里创建.htaccess文件yii-application1/.htaccess

Options +FollowSymlinks
RewriteEngine On

# deal with backend first
RewriteCond %{REQUEST_URI} /(backend)
RewriteRule ^backend/assets/(.*)$ backend/web/assets/$1 [L]
RewriteRule ^backend/css/(.*)$ backend/web/css/$1 [L]
RewriteRule ^backend/image/(.*)$ backend/web/image/$1 [L]

RewriteCond %{REQUEST_URI} !/backend/web/(assets|css|image)/
RewriteCond %{REQUEST_URI} /(backend)
RewriteRule ^.*$ backend/web/index.php [L]


RewriteCond %{REQUEST_URI} /(assets|css|js|img|font)
RewriteRule ^assets/(.*)$ frontend/web/assets/$1 [L]
RewriteRule ^css/(.*)$ frontend/web/css/$1 [L]
RewriteRule ^js/(.*)$ frontend/web/js/$1 [L]
RewriteRule ^image/(.*)$ frontend/web/image/$1 [L]

RewriteCond %{REQUEST_URI} !/(frontend|backend)/web/(assets|css|js|image|font)/
RewriteCond %{REQUEST_URI} !index.php
RewriteCond %{REQUEST_FILENAME} !-f [OR]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ frontend/web/index.php

第2步

现在创建一个components/Request.php文件common的目录和文件编写下面的代码。

Request.php文件

<?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;
     }

     public function resolvePathInfo(){
        if($this->getUrl() === $this->adminUrl){
            return "";
        }else{
            return parent::resolvePathInfo();
        }
     }
  }
?>

步骤：3

现在安装组件。下面写在代码frontend/config/main.php和backend/config/main.php分别文件。

//Frontend
'components' => [
    'user' => [
        'identityClass' => 'common\models\User',
        'enableAutoLogin' => true,
        'identityCookie' => [
            'name' => '_frontendUser', // unique for frontend
        ]
    ],
    'session' => [
        'name' => 'PHPFRONTSESSID',
        'savePath' => sys_get_temp_dir(),
    ],
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
            '<alias:>' => 'site/<alias>',
        ],
    ],
    'request'=>[
        'cookieValidationKey' => '[gfhjghsdjks44fdf4fgf4fgfg5645ggxcvvc]',
        'csrfParam' => '_frontendCSRF',
        'class' => 'common\components\Request',
        'web'=> '/frontend/web'
    ],
]

//Backend 
'components' => [
    'user' => [
        'identityClass' => 'common\models\User',
        'enableAutoLogin' => false,
        'identityCookie' => [
            'name' => '_backendUser', // unique for backend
        ]
    ],
    'session' => [
        'name' => 'PHPBACKSESSID',
        'savePath' => sys_get_temp_dir(),
    ],
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
        ],
    ],
    'request'=>[
        'cookieValidationKey' => '[ruiqwybnddiogj786789hzcassdas9dasdjufi]',
        'csrfParam' => '_backendCSRF',
        'class' => 'common\components\Request',
        'web'=> '/backend/web',
        'adminUrl' => '/backend'
    ],
]

你domain.com/frontend/web问题解决了按照上面的steps 。你可以访问index的网页domain.com/frontend/web使用domain.com 。

现在你可以使用你访问图像

<?php echo Html::img('uploads/ring.jpg') ?>

您也可以访问domain.com/frontend/web/image使用下面的代码

<?= Html::img(Yii::getAlias('@web').'/image/xyz.png', ['class' => 'retina']); ?>

还你使用这个根目录路径Yii::getAlias('@webroot')

Answer 2:

您还可以在config文件夹中的文件web.php使用ALISE配置阵列内像

 'aliases' => [
    '@uploads' => '@app/web/upload',
],

并在您想要像使用任何

 <?= Html::img("@uploads/image/xyz.png", ['class' => 'retina']); ?>
