路由添加参数

Route::any('/product', [app\index\controller\Index::class, 'product']);

// 匹配 /user/123 /user/abc
Route::any('/user/{id}', [app\controller\User:class, 'get']);

namespace app\controller;
class User
{
    public function get($request, $id)
    {
        return response('接收到参数'.$id);
    }
}
