愤怒的小菜

user

{

  "_id":ObjectId(...),

  "uid":1,

  "ncikname":'xiaocai',

  "goods":[

      {

          "gid":22,

          "name":"xxxx",

          "price":24.5,

          "comment":[{},{},{}]

       },

      {},

      {}

   ]

}

如上结构，我需要分页查询出uid=1的goods列表。

db.user.find({"uid":1},{goods:{$slice:[0,1]}});
