CakePHP 2.1.0：如何创建“下来维护”页

问题描述

我试图实现使用CakePHP 2.1.0。我很接近实现这一点，但我遇到两个问题，我可以使用一些帮助。首先，这里是所有相关的代码（六个文件）：

I'm trying to implement something like Mark Story's "Down for Maintenance" page using CakePHP 2.1.0. I'm pretty close to achieving this, but I'm running into two issues that I could use some help with. First of all, here is all of the relevant code (six files):

1）app / Config / bootstrap.php：

1) app/Config/bootstrap.php:

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

2）app / Config / core.php：

2) app/Config/core.php:

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

...

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

3）app / Controller / AppController.php：

3) app/Controller/AppController.php:

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

$ b $ p 4）app / Lib / Error / Exception / DownForMaintenanceException.php： p>

4) app/Lib/Error/Exception/DownForMaintenanceException.php:

<?php
class DownForMaintenanceException extends CakeException {}

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

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）app / View / Errors / down_for_maintenance.ctp ：

6) app/View/Errors/down_for_maintenance.ctp:

<p>Down for Maintenance</p>

现在，对于我遇到的两个问题。首先，这个代码只有当调试设置高于1时才有效。有什么我可以做的吗？这是否表明我要这个错误的方式？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 boolean 值，但是app / View / Layouts / default.ctp文件将其视为字符串。我可以做些什么？

Now, for the two issues I'm experiencing. First, this code only works when debug is set higher than 1. Is there anything I can do about that? Does that indicate that I'm going about this the wrong way? The second issue is that, although I'm setting the "isMobile" and "logged_in" view variables to boolean values in the "downForMaintenance" method, the "app/View/Layouts/default.ctp" file is seeing them as strings. What can I do about that?

谢谢！

推荐答案

是cakephp的快速和脏的维护页面

here is a quick and dirty maintenance page for cakephp

in public index.php

in public index.php

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

然后只需要更改MAINTENANCE = 1，仍然可以从您的家/办公室查看。

Then just change MAINTENANCE = 1 when you want to take your site down and it will still be viewable from your home/office.
