如何在Laravel 4中设置任务调度？ [英] How to set up task scheduling in Laravel 4?

问题描述

我有一个网站在Laravel 4.2，我们有一个月会员30个学分。即使用户不使用它们，他们应该在 valid_till 日期到期。

I've a website made in Laravel 4.2 and we have a monthly membership with 30 credits. Even if user doesn't use all of them, they should expire at valid_till date.

我希望有一段代码，它将在每天晚上12点运行，并在每个人的帐户中将信用值设置为0 valid_till date等于昨天或之前。

I wish to have a piece of code which will run at 12 am every night and will set credit as 0 in everyone's account who's valid_till date is equal to yesterday or before that.

如果在laravel 5.1中可以有任务调度，它每天在特定的时间运行一个函数，这将是完美的。

我知道cron可以设置在Laravel 4.2，使用命令，但我不能理解如何使用它在我的case。

If there could be something like task scheduling in laravel 5.1, which runs a function on particular time of day daily, that would be perfect.
I know cron can be set up in Laravel 4.2, using commands but I'm unable to understand how to use it in my case?

推荐答案

在app / commands中创建一个类似下面的文件，使用更新函数替换fire方法中的注释。

Create a file like the following in app/commands, replace my comment in the fire method with your update function.

<?php

use Illuminate\Console\Command;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputArgument;

class setCreditToZero extends Command {

    /**
     * The console command name.
     *
     * @var string
     */
    protected $name = 'set:zero';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Command description.';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function fire()
    {
        // your update function here
    }

    /**
     * Get the console command arguments.
     *
     * @return array
     */
    protected function getArguments()
    {
        return [

        ];
    }

    /**
     * Get the console command options.
     *
     * @return array
     */
    protected function getOptions()
    {
        return [

        ];
    }

}

在app / start注册命令/artisan.php

Register your command in app/start/artisan.php

Artisan::add(new setCreditToZero);

现在使用终端上的命令设置cronjob

Now set a cronjob using command on your terminal

crontab -e

cronjob with this line

And in this file set a cronjob with this line

0 0 * * * /usr/bin/php /path/to/laravel/baseDir/artisan set:zero
