Laravel 权限管理涉及 中的节点与关系 加深记忆，自用

    // 构建用户显示菜单节点
    public function getMenus($pid=0)
    {
        $menus = self::select(['id','pid','name','route'])->where(['type'=>'GET','status'=>'Y','pid'=>$pid])->with(['SecondMenus'=>function($query){
            $query->where(['type'=>'GET','status'=>'Y'])->select(['id','pid','name','route']);
        }])->get();

        return $menus;
    }

    // 获取全部节点
    public function getAllMenus($pis = 0)
    {
        $menus = self::select(['id','pid','name','route'])->where(['type'=>'GET','pid'=>$pid])->with(['SecondMenus'=>function($query){
            $query->select(['id','pid','name','route']);
        }])->get();

        return $menus;
    }

    public function SecondMenus()
    {
        return $this->hasMany(AdminNode::class,'pid','id');
    }

主要自己学习使用， 结合with 和一对多的使用，构建出权限的结构树
