启动代码,加ssl证书

namespace app\gateway\controller;
use \Workerman\Worker;
use \GatewayWorker\Register;

use \GatewayWorker\Gateway;
use \GatewayWorker\BusinessWorker;
use \Workerman\Autoloader;

        $worker = new BusinessWorker();
        $worker->name = 'mygate';
        $worker->count = 4;
        $worker->registerAddress = '127.0.0.1:1239';
        //设置处理业务的类,此处制定Events的命名空间
        $worker->eventHandler = '\app\gateway\controller\Events';
        // 初始化 gateway 进程
         $context = array(

        //运行所有Worker;

启动命令

```php
php server.php start  -d //-d后台运行
