CakePHP 2.1.0 : How to Create "Down for Maintenance" Page

Question

我正在尝试实现类似 Mark Story's "Down for Maintenance" page使用 CakePHP 2.1.0。我非常接近实现这一目标，但我遇到了两个问题，我可以使用一些帮助。首先，这里是所有相关代码(六个文件):

1)应用程序/配置/bootstrap.php:

Configure::write('App.maintenance', true);

2) 应用/配置/core.php:

Configure::write('debug', 1);

...

Configure::write('Exception', array(
    'handler' => 'ErrorHandler::handleException',
    'renderer' => 'AppExceptionRenderer',
    'log' => true
));

3) 应用程序/ Controller /AppController.php:

if (Configure::read('App.maintenance') == true) {
    App::uses('DownForMaintenanceException', 'Error/Exception');
    throw new DownForMaintenanceException(null);
}

4) 应用程序/Lib/错误/异常/DownForMaintenanceException.php:

<?php
class DownForMaintenanceException extends CakeException {}

5) app/Lib/Error/AppExceptionRenderer.php:

<?php
App::uses('ExceptionRenderer', 'Error');

class AppExceptionRenderer extends ExceptionRenderer {
    function _outputMessage($template) {
        // Call the "beforeFilter" method so that the "Page Not Found" page will
        // know if the user is logged in or not and, therefore, show the links that
        // it is supposed to show.

        if (Configure::read('App.maintenance') == false)
        {
            $this->controller->beforeFilter();
        }

        parent::_outputMessage($template);
    }

    public function downForMaintenance() {
        $url = $this->controller->request->here();
        $code = 403;
        $this->controller->response->statusCode($code);
        $this->controller->set(array(
            'code' => $code,
            'url' => h($url),
            'isMobile' => $this->controller->RequestHandler->isMobile(),
            'logged_in' => false,
            'title_for_layout' => 'Down for Maintenance'
        ));
        $this->_outputMessage($this->template);
    }
}

6) 应用程序/ View /错误/down_for_maintenance.ctp:

<p>Down for Maintenance</p>

现在，对于我遇到的两个问题。首先，此代码仅在调试设置高于 1 时才有效。对此我能做些什么吗？这是否表明我正在以错误的方式解决这个问题？第二个问题是，尽管我在“downForMaintenance”方法中将“isMobile”和“logged_in” View 变量设置为 bool 值，但“app/View/Layouts/default.ctp”文件将它们视为字符串。我能做些什么呢？

谢谢!

Answer 1

这是 cakephp 的快速而肮脏的维护页面

在公共(public) index.php 中

define('MAINTENANCE', 0); 
if(MAINTENANCE > 0 && $_SERVER['REMOTE_ADDR'] !='188.YOUR.IP.HERE')
{
require('maintenance.php'); die(); 
}

然后，当您想要关闭您的网站时，只需更改 MAINTENANCE = 1，它仍然可以从您的家/办公室查看。
