自定义输出器
  1. 实现该接口
<?php

declare(strict_types=1);

namespace Guanguans\LaravelSoar\Contracts;

use Illuminate\Support\Collection;

interface Output
{
    /**
     * @param \Illuminate\Console\Events\CommandFinished|\Symfony\Component\HttpFoundation\Response $dispatcher
     */
    public function shouldOutput($dispatcher): bool;

    /**
     * @param \Illuminate\Console\Events\CommandFinished|\Symfony\Component\HttpFoundation\Response $dispatcher
     */
    public function output(Collection $scores, $dispatcher);
}
  1. config/soar.php 中配置输出器即可
<?php

return [
    ...
    'output' => [
        ...
        Guanguans\LaravelSoar\Outputs\LogOutput::class => ['channel' => 'daily', 'level' => 'warning'],
        ...
    ],
    ...
];
