Question

简单的问题。我使用Yii2高级模板。在apache我有DocumentRoot "{$path}/www/yii-application1/frontend/web"。如何访问/www/yii-application1/uploads以向用户显示图像？以下code无效：

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

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

步骤：1

首先在此处创建 .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

步骤：2

现在在components/Request.php目录中创建一个common文件，并在此文件中写下以下代码。

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。分别在frontend/config/main.php和backend/config/main.php文件中写下以下代码。

//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'
    ],
]

您的domain.com/frontend/web问题已解决，可以按照上述steps进行操作。并且您可以使用index访问domain.com/frontend/web的{{1}}页面。

现在您可以使用

访问您的图像

domain.com

您也可以使用以下代码访问<?php echo Html::img('uploads/ring.jpg') ?>

domain.com/frontend/web/image

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

获取webroot路径

Answer 2

你也可以在配置文件夹的web.php文件中使用alise inside config数组，如

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

并在任何你想要的地方使用它

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

Yii2。访问更高级别的文件夹
