[TOC] 新增 `App/Event/Event.php` 文件 ``` namespace App\Event; use EasySwoole\Component\Container; use EasySwoole\Component\Singleton; class Event extends Container{ use Singleton; function set($key, $item) { if (is_callable($item)){ return parent::set($key, $item); }else{ return false; } } function hook($event,...$arg){ $call = $this->get($event); if (is_callable($call)){ return call_user_func($call,...$arg); }else{ return null; } } } ``` 在框架的initialize事件中进行注册事件: ``` \App\Event\Event::getInstance()->set('test', function ($arg,$arg1) { echo "test event:{$arg},{$arg1}\n"; }); \App\Event\Event::getInstance()->set('test2', function ($arg,$arg1) { echo "test event:{$arg},{$arg1}\n"; }); //别处调用 \App\Event\Event::getInstance()->hook('test','123','222'); //删除 test2 的hook \App\Event\Event::getInstance()->delete('test2'); //清空所有 hook //\App\Event\Event::getInstance()->clear(); \App\Event\Event::getInstance()->hook('test2','abc','def'); ```
