### 未使用自定义进程相关代码
```php

<?php

namespace App\Console\Commands
use Illuminate\Console\Command;
use Illuminate\Support\Carbon;
use Swoole\Coroutine;
use function Swoole\Coroutine\run;

class test extends Command
{

protected $signature = 'test';

public function handle()
    {
        run(function () {
            while (true){
                Coroutine::create(function() {
                  var_dump(file_get_contents("http://www.xinhuanet.com/"));
                });
         });
    }
}

```

### 使用自定义进程相关代码
```php
<?php

namespace App\Processes;

use Hhxsv5\LaravelS\Swoole\Process\CustomProcessInterface;
use Swoole\Http\Server;
use Swoole\Process;
use Swoole\Runtime;
use Swoole\Coroutine;
use function Swoole\Coroutine\run;

class TestProcess implements CustomProcessInterface
{
    /**
     * @var bool 退出标记，用于Reload更新
     */
    private static $quit = false;

public static function callback(Server $swoole, Process $process)
    {
        Runtime::enableCoroutine(true,SWOOLE_HOOK_SLEEP);
        Coroutine::create(function() {
            while (1){
                var_dump(1);
            }
        });
    }

// 要求：LaravelS >= v3.4.0 并且 callback() 必须是异步非阻塞程序。
    public static function onReload(Server $swoole, Process $process)
    {
        self::$quit = true;
    }

// 要求：LaravelS >= v3.7.4 并且 callback() 必须是异步非阻塞程序。
    public static function onStop(Server $swoole, Process $process)
    {
        self::$quit = true;
    }
}

```

### 你期待的结果是什么？实际看到的错误信息又是什么？
