我正在尝试使用 CakePHP 2.1.0实现类似Mark Story 的“Down for Maintenance”页面。我非常接近实现这一目标,但我遇到了两个我可以使用一些帮助的问题。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/控制器/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/视图/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,虽然我在“downForMaintenance”方法中将“isMobile”和“logged_in”视图变量设置为布尔值,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!
