如何跨多个域重用代码? [英] How to reuse code across multiple domains?

问题描述

我只是使用 Yii 框架构建了一个 CMS 框架.我想将 CMS 部署到多个域.

I just build a CMS framework using Yii framework. I want to deploy the CMS to multiple domains.

/home/root/www/domain1.com
/home/root/www/domain2.com
/home/root/www/domain3.com
/home/root/www/domain4.com

我想重用css文件和受保护文件夹下的所有文件，这样一旦我更新了css和受保护文件夹中的文件，所有域都应该反映更改.

I want to reuse the css files and all the files under protected folder, so that once I update css and the files in the protected folder, all the domains should reflect the change.

推荐答案

是的，Yii 支持这个.事实上，这就是我配置一些网站的方式.

Yes, Yii supports this. In fact, this is how I have some websites configured.

(当然，前提是您的所有站点都在同一台服务器上.但我看到 Evan 有这个.这在跨服务器上是行不通的.)

(Of course, this is predicated on having all your sites on the same server. But I see that Evan has this. This would not work accross servers.)

首先，这将要求您将代码移出 Web 根目录并移至文档根目录中.请参阅此处.

Firstly, it would require that you move your code out of the web-root and into the document root. See here.

其次，它要求你使用 Yii AssetsBase.请参阅此处和那里.我发现资产管理需要配置(但使用起来很轻松).这就是我最终的结果:

Secondly, it requires that you use Yii AssetsBase. See here and there. I found the asset management a bear to configure (but a breeze to work with). This is what I ended up with:

在 components/Controller.php 中包含以下内容:

In components/Controller.php include the following:

    /**
     * @var registers which js, css, images have been published
     * See: http://www.yiiframework.com/wiki/311/assetmanager-clearing-browser-s-cache-on-site-          update/
 */

    private $_assetsBase;

    public function getAssetsBase()
    {
            if ($this->_assetsBase === null) {
                Yii::app()->assetManager->newDirMode = 0755;        
                Yii::app()->assetManager->newFileMode = 0644;        

                    $this->_assetsBase = Yii::app()->assetManager->publish(
                            Yii::getPathOfAlias('application.assets'),
                            false,
                            -1,
                            defined('YII_DEBUG') && YII_DEBUG
                    );
            }
            return $this->_assetsBase;
    }

以上假设你的 JS、CSS 和图片位置如下:

The above presupposes that your JS, CSS and images are located as follows:

protected/assets/js/mobiscroll-2.3.custom.min.js
protected/assets/css/mobiscroll-2.3.custom.min.css
protected/assets/img/einstein.png

然后在您的视图中，按如下方式调用您的资产:

Then in your views, call your assets as follows:

<?php
$cs->registerScriptFile($this->assetsBase.'/js/mobiscroll-2.3.1/js/mobiscroll-2.3.custom.min.js');
$cs->registerCssFile($this->assetsBase.'/js/mobiscroll-2.3.1/css/mobiscroll-2.3.custom.min.css');
?>

<img src="<?php echo $this->assetsBase ?>/img/einstein.png">

最后，在您对 JS 或 CSS 进行更改后，您将希望在所有用户的浏览器中强制刷新缓存.您可以通过触摸(原始)资产目录来完成此操作.这将强制 Yii 重新散列(已发布的)资产目录.随后，您的 JS &CSS 将在所有用户的浏览器中刷新.做这样的事情:

Finally, after you have made changes to your JS or CSS, you will want to force a cache refresh in all users' browsers. You do this by touching the (original) assets directory. This will force Yii to rehash the (published) assets directory. Subsequently, your JS & CSS will be refreshed in all users' browsers. Do something like this:

$command = 'touch /path/to/your/website/protected/assets';
exec ( $command.' 2>&1',  $output , $result  );
if ($result === 0) {
    $message = 'Assets have been pointed; a new directory should now be hashed';
} else {
    $message = 'Looks like something went wrong. Assets not pointed?';
} // END if
