//        auth登录
        $data=auth()->attempt(['username'=>$postData['username'],'password'=>$postData['password']]);

  public function handle(Request $request, Closure $next)
    {
//        检测用户是否登录
        if(!auth()->check()){
            return redirect('admin/login')->withErrors(['error'=>'请登录']);
        }
        return $next($request);
    }

//        取出缓存中的拥有权限
        $node=session('node');
//        dd($node);
//        权限验证
        if(auth()->user()['username']!=config('admin.admin')){
            if(!in_array($request->path(),$node)){
                return redirect('welcome')->withErrors('权限不足');
            }
        }
        return $next($request);
    }
