Cron Job with Laravel 4
提问by TheSteed
I'm trying to find out how to set up a cron job in Laravel 4, and the command I would need to run in artisan for it.
我试图找出如何在 Laravel 4 中设置 cron 作业，以及我需要在 artisan 中运行的命令。
In Laravel 3, there were Tasksbut these don't seem to be there anymore and there is no documentation as to how to do it...
在 Laravel 3 中，有Tasks但这些似乎不再存在，并且没有关于如何做的文档......

Below I detail a tutorial for using commandsin Laravel 4with cron. I have divided into four steps to make it easier to follow.
下面我详细使用教程commands中Laravel 4：用cron。为了更容易理解，我分为四个步骤。
STEP #1: Create a command in Laravel 4:
第 1 步：在 Laravel 4 中创建一个命令：
php artisan command:make RefreshStats
With command above, Laravel will create a file named RefreshStats.phpin directory app/commands/
使用上面的命令，Laravel 将创建一个RefreshStats.php在目录中命名的文件 app/commands/
RefreshStats.phpit's a file like this:
RefreshStats.php它是一个这样的文件：
use Illuminate\Console\Command;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputArgument;
class RefreshStats extends Command {
protected $name = 'command:name';
protected $description = 'Command description.';
public function __construct() {
parent::__construct();
}
public function fire(){
}
protected function getArguments() {
return array(
array('example', InputArgument::REQUIRED, 'An example argument.'),
);
}
protected function getOptions() {
return array(
array('example', null, InputOption::VALUE_OPTIONAL, 'An example option.', null),
);
}
}
STEP #2: Simple "configuration" of RefreshStats file:
第 2步：RefreshStats 文件的简单“配置”：
You should change this line:
你应该改变这一行：
protected $name = 'command:name';
to something like this:
像这样：
protected $name = 'refresh:stats';
If you don't need arguments (same for options), change this line:
如果您不需要参数（与 options 相同），请更改此行：
protected function getArguments() {
return array(
array('example', InputArgument::REQUIRED, 'An example argument.'),
);
}
to:
到：
protected function getArguments() {
return array();
}
And now pay attentionto the firefunction. The command will execute source code that is wrote in that function. Example:
而现在注重的fire功能。该命令将执行在该函数中编写的源代码。例子：
public function fire(){
echo "Hello world";
}
STEP #3: Register the command:
第 3 步：注册命令：
You need to register the command. So open app/start/artisan.phpfile, and add one line as below:
您需要注册该命令。所以打开app/start/artisan.php文件，并添加如下一行：
Artisan::add(new RefreshStats);
STEP #4: Create CRONscheduled task:
第 4步：创建CRON计划任务：
Finally, you can add a scheduled task as follow:
最后，您可以添加计划任务如下：
crontab -e
And add a line (run command every 30 minutes) like below:
并添加一行（每 30 分钟运行一次命令），如下所示：
*/30 * * * * php path_laravel_project/artisan refresh:stats
And all will work automagically!
并且一切都会自动运行！

Alternative, if you don't like commands there is an unofficial Laravel 4 cron package: https://github.com/liebig/cron
或者，如果你不喜欢命令，有一个非官方的 Laravel 4 cron 包：https: //github.com/liebig/cron
