配置和测试Laravel任务计划 [英] Configure and Test Laravel Task Scheduling

问题描述

• Laravel版本: 5.1.45(LTS)

PHP版本: 5.6.1

我正在尝试使用Laravel每1分钟运行一条命令任务计划.

I'm trying to run a command every 1 minute using Laravel Task Scheduling.

我已将此行添加到我的cron选项卡文件中

I've added this line to my cron tab file

* * * * * php artisan schedule:run >> /dev/null 2>&1

这是我的/app/Console/Kernel.php

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        \App\Console\Commands\Inspire::class,
    ];

    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('inspire')->hourly();
        $schedule->command('echo "Happy New Year!" ')->everyMinute(); //<---- ADD HERE        }
}

我已添加此行$schedule->command('echo "Happy New Year!" ')->everyMinute();

我该如何测试?

如何触发我的回声显示?

How do I trigger my echo to display ?

我怎么知道我做错了什么?

How do I know if what I did is not wrong ?

此刻我正在征求任何建议.

I'm opening to any suggestions at this moment.

任何对此的提示/建议/帮助将不胜感激！

Any hints / suggestions / helps on this be will be much appreciated !

推荐答案

command()运行工匠命令.您要实现的目标-向OS发出命令-由exec('echo "Happy New Year!"')

command() runs an artisan command. What you're trying to achieve - issuing a command to the OS - is done by exec('echo "Happy New Year!"')

测试取决于您要测试的内容:

Testing depends on what you want to test:

• 调度程序(每分钟)是否正常工作?

在这种情况下，您不必这样做.已在原始框架代码中进行了测试.

In this case, you don't have to. It is tested in the original framework code.

• 命令是否成功?

好吧，您可以手动运行php artisan schedule:run并查看输出.

Well, you can manually run php artisan schedule:run and see the output.

默认情况下(>> /dev/null 2>&1)，调度程序不产生任何输出.但是，您可以通过链接writeOutputTo()或appendOutputTo()( https://laravel.com/docs/5.1/scheduling#task-output ).

The scheduler does not produce any output on default (>> /dev/null 2>&1). You can, however, redirect the output of the runned scripts to any file by chaining writeOutputTo() or appendOutputTo() (https://laravel.com/docs/5.1/scheduling#task-output).

有关更复杂的逻辑，请编写控制台命令( https://laravel.com /docs/5.1/artisan#writing-commands )并使用command()-这样，您就可以编写漂亮的，可测试的代码.

For more complex logic, write a console command instead (https://laravel.com/docs/5.1/artisan#writing-commands) and use command() - this way you can write nice, testable code.
