Cron 调度器 CakePHP 2.0

2021-12-21 00:00:00 cron php cakephp

我正在使用 CakePHP 2.0 并且一直在尝试设置一个 cronjob 以在控制器中执行一个方法.我一直在发疯，查看各种教程和随机网站，看看我是否能找到解决方案.

I am using CakePHP 2.0 and have been trying to setup a cronjob to execute a method in a controller. I've been going nuts, looking over various tutorials and random sites to see if I could find a solution.

我收到的错误是:

Undefined variable: argc [APP/webroot/cron_dispatcher.php, line 83

这是我的 app/webroot/ 目录中 cron_dispatcher.php 文件的底部.

Here is the bottom of the cron_dispatcher.php file in my app/webroot/ directory.

if (!include(CORE_PATH . 'cake' . DS . 'bootstrap.php')) {
        trigger_error("CakePHP core could not be found.  Check the value of CAKE_CORE_INCLUDE_PATH in APP/webroot/index.php.  It should point to the directory containing your " . DS . "cake core directory and your " . DS . "vendors root directory.", E_USER_ERROR);
    }
    if (isset($_GET['url']) && $_GET['url'] === 'favicon.ico') {
    return;
    } else {
      define('CRON_DISPATCHER',true);
    if($argc >= 2) {
        $Dispatcher= new Dispatcher();
        $Dispatcher->dispatch($argv[1]);
        }
    }

我找不到这些变量($argv 和 $argc)的定义位置.它们没有在 dispatcher.php 文件本身的任何地方定义.我搜索了谷歌无济于事.我不是 100% 确定 Dispatcher 是如何工作的，但任何帮助将不胜感激.谢谢.

I cannot find where these variables ($argv and $argc) are defined. They aren't defined anywhere in the dispatcher.php file itself. I searched Google to no avail. I'm not 100% sure how the Dispatcher works, but any help would be greatly appreciated. Thanks.

== 更新GoDaddy 的共享主机不允许您更改 argc argv 的设置.

== UPDATE GoDaddy's shared hosting doesn't allow you to change the settings of argc argv.

推荐答案

如果其他人有兴趣，

在新的 CakePHP 2.0.5 中，您将在 webroot 文件夹中创建一个 index.php:

In the new CakePHP 2.0.5, you will an index.php in webroot folder:

复制这个文件，命名为cron_dispatcher.php，放到同一个目录下(webroot)

Copy this file and name it cron_dispatcher.php, and place it into the same directory (webroot)

您会在最底部找到此代码:

You will find this code at the very bottom:

$Dispatcher = new Dispatcher();
$Dispatcher->dispatch(new CakeRequest(), new CakeResponse(array('charset' => Configure::read('App.encoding'))));

将底部改为

define('CRON_DISPATCHER',true);
$Dispatcher = new Dispatcher();
$Dispatcher->dispatch(new CakeRequest($argv[1]), new CakeResponse(array('charset' => Configure::read('App.encoding'))));

您在这里做了两件事:将 CRON_DISPATCHER 设置为 true，并传递环境变量 ($argv[1]).

You're doing two things here: Setting CRON_DISPATCHER to true, and passing environment variables ($argv[1]).

在你的控制器中，在你做任何其他事情之前添加这一行:

In your controller, add this line before you do anything else:

if (!defined('CRON_DISPATCHER')) { $this->redirect('/'); exit(); }

这将确保访问 yoursite.com/controller/cronaction 的人将无法运行您的脚本.

This will ensure people going to yoursite.com/controller/cronaction won't be able to run your script.

在 webroot 中的 htaccess 文件中，添加:

In your htaccess file in webroot, add this: 

<Files  "cron_dispatcher.php">
    Order deny,allow
    Deny from all
</Files>

这将确保访问 yoursite.com/cron_dispatcher.php 的人无法运行它.

This will ensure poeple going to yoursite.com/cron_dispatcher.php won't be able teo run it.

现在使用以下命令设置 cron 作业:

Now set up the cron job using something like the command: 

php /home/yoursite/public_html/cakephp/app/webroot/cron_dispatcher.php /controller/cronjobaction
