slim4获取所有路由

发表于 分类于 2.7k 2 分钟

可能是因为slim框架大家使用少，加上官方文档也非常的简单，这里整理一下slim4所有所有路由的方式；问：为什么要获取所有的路由？ 答：肯定是用来做权限控制啦~~~

路由设置

本文的方式在通过中间件的方式去获取所有路由，在用户登录的时候会触发中间件去整理所有的路由

$app->group('/admin', function(Group $group) use ($app){
    $group->post('/go_login', LoginController::class.':login')->addMiddleware(new AuthNodesMiddleware($app));
});

中间件整理所有路由

中间件中的逻辑主要是获取并解析所有的路由，然后整理存储在表里，每次登录的时候都需要重新整理
