Laravel 5:在控制台内核的schedule()函数中使用Cache ::或DB ::

问题描述

我试图在Laravel 5中以用户配置的不同时间间隔运行Artisan控制台命令.我已经构建了控制台命令，并拥有一个数据库(使用Eloquent模型)，该数据库具有运行频率"配置值.

I'm trying to run an Artisan console command in Laravel 5 at varying, user-configured time intervals. I have built the console command and have a database (with Eloquent model) holding a "run frequency" configuration value.

在App\Console\Kernel.php的schedule()函数中，我想将此值从数据库中拉出，并根据需要根据需要在适当的时候运行命令.

Within the schedule() function of App\Console\Kernel.php I'd like to pull this value out of the database and run the command as and when needed based on this value.

使用带有或不带有use DB;的DB::table()...时，我会收到一个Fatal error: Class 'DB' not found，如果我也尝试使用Cache::...函数，也会发生同样的情况.

I receive a Fatal error: Class 'DB' not found when using DB::table()... with or without use DB;, and the same happens if I try to use Cache::... functions too.

我假设无法从App\Console\Kernel.php文件的schedule()函数中访问IoC容器.有没有人有类似的发现，并且找到了一个优雅的解决方法?

I'm assuming the IoC container isn't accessible from within the schedule() function of App\Console\Kernel.php file. Has anyone had similar and found an elegant workaround?

我的简化代码是:

<?php namespace App\Console;

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

class Kernel extends ConsoleKernel {

    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $settings = Cache::get('settings');
    }

和错误:

php artisan schedule:run
PHP Fatal error:  Class 'Cache' not found in /home/vagrant/projects/project/dir/api/app/Console/Kernel.php on line 26

任何帮助将不胜感激
