README
事件相比较中间件的优势是事件比中间件更加精准定位(或者说粒度更细),并且更适合一些业务场景的扩展。例如,我们通常会遇到用户注册或者登录后需要做一系列操作,通过事件系统可以做到不侵入原有代码完成登录的操作扩展,降低系统的耦合性的同时,也降低了BUG的可能性。
安装
composer require yzh52521/webman-event
配置
事件配置文件 config/plugin/yzh52521/event/app.php
内容如下
return [ 'enable' => true, 'events' =>[ // 事件监听 'listener' => [ 'test' => [ \app\listeners\TestListeners::class, ], ], // 事件订阅器 'subscriber' => [ \app\subscribes\TestSubscribe::class, ], ] ];
快速开始
事件类:Test
namespace app\events; class Test { public $data = []; public function __construct($data) { $this->data = $data; } }
监听类
namespace app\listeners; use app\events\Test; class TestListeners { public function __construct() { } /** * 处理事件 * @return void */ public function handle(Test $event) { // 控制台打印 var_dump('listener'); var_dump($event->data); } }
订阅类
namespace app\subscribes; use app\events\Test; class TestSubscribe { public function handleTest(Test $event) { var_dump('subscribe'); var_dump($event); } public function subscribe($events) { $events->listen( Test::class, [TestSubscribe::class, 'handleTest'] ); } }
调用触发事件
event(new Test('event data'));
or
event('test',[new Test('event data')]);
