将参数从中间件传递到控制器

Question

I have a middleware which does a query and I would like to pass the result back to my controller. Is it possible? I'm using Laravel 5.

public function handle($request, Closure $next)
    {
        if ($this->auth->guest()) {
            if ($request->ajax()) {
                return view('errors.401');
            } else {
                return redirect()->guest('auth/login');
            }
        }

        $cur_route = Request::segment(1);

        $result = DB::table('t_user_acl_masters')->join('t_function_details', 't_function_details.functiondtl_id', '=' ,'t_user_acl_masters.functiondtl_id')
                                                ->where('t_function_details.routename', '=', $cur_route)
                                                ->where('t_user_acl_masters.user_id', '=', $request->user()->user_id)
                                                ->select('t_user_acl_masters.viewaccess','t_user_acl_masters.addaccess','t_user_acl_masters.editaccess','t_user_acl_masters.deleteaccess')
                                                ->first();

        if(!empty($result)) {
            if ($result->viewaccess != 'y') {
                return view('errors.401');
            }
        }

        return $next($request, $result);
    }

Controller:

public function __construct(Request $request)
    {
        parent::__construct();
        $this->middleware('auth');
        $this->user = Auth::user();
        $this->acl = $request->attributes->get('acl');
    }

public function index(Request $request){
        dd($this->acl);
}

I have injected it in to the attributes of request, but I can't get it from my function. If I dd($request->attributes->get('acl')) in my index() function, data is available.

You can store the variable in the session:

Session::flash('result', $result);

Then you can retrieve it in your controller like so:

Session::get('result');
