# **interfaces接口** 目錄結構 ``` ├─interfaces │ JobInterface.php │ ListenerInterface.php │ MiddlewareInterface.php ``` * JobInterface 屬于消息隊列接口類 ## ListenerInterface 屬于事件監聽接口類 創建一個事件監聽類，并且必須完成`handle`方法 ``` <?php crmeb\listeners; use crmeb\interfaces\ListenerInterface; class UserListener implements ListenerInterface { public function handle($event){ } } ``` ## 注冊UserListener事件 注冊容器地址：\app\adminapi\event.php ``` return [ 'listen' => [ 'AppInit' => [], 'HttpRun' => [], 'HttpEnd' => [], 'LogLevel' => [], 'LogWrite' => [], 'UserLogin'=>[ \crmeb\listeners\user\UserListener::class ] ] ]; ``` ## MiddlewareInterface 屬于中間件接口類 在創建中間件的時候可以繼承接口類,并且必須完成`handle`方法 ``` <?php namespase app\http\middleware; use crmeb\interfaces\MiddlewareInterface; class AdminLogMiddleware implements MiddlewareInterface { /** * @param Request $request * @param \Closure $next * @return mixed */ public function handle(Request $request, \Closure $next) { //具體操作邏輯 } ``` 路由調用 ``` Route::group('export', function () { })->middleware([ \app\adminapi\middleware\AdminLogMiddleware::class ]); ```
