laravel5.1使用entrust实现权限管理遇到的问题。

public function handle($request, Closure $next)
    {
        if ($this->auth->guest()) {
            if ($request->ajax() || $request->wantsJson()) {
                return response('Unauthorized.', 401);
            } else {
                return redirect()->guest('auth/login');
            }
        } else {
            if (!$this->auth->user()->can(Route::getCurrentRoute()->getPath())) {
                if ($request->ajax() || $request->wantsJson()) {
                    return response('您没有该操作权限', 403);
                } else {
                    return response()->view('errors.403');
                }
            }
            view()->share('menuData', $this->getMenu());
            return $next($request);
        }
    }

始终提示没有权限,求教！

if (!$this->auth->user()->can(Route::getCurrentRoute()->getPath())) {
                if ($request->ajax() || $request->wantsJson()) {
                    return response('您没有该操作权限', 403);
                } else {
                    return response()->view('errors.403');
                }
            }

始终会进入到403,我已经给admin赋予了所有权限.
