后端数据格式

1. 常规数据格式，例如：

   {
    "code": 0,
    "msg": "",
    "data": [{
        "id": 1,
        "title": "title1 content",
        "time": 1510363800000
    }, {
        "id": 2,
        "title": "title2 content",
        "time": 1510212370000
    }, {
        "id": 3,
        "title": "title3 content",
        "time": 1510212370000
    }]
   }
   

2. 涉及到分页的数据格式，多了 count 一项，例如：

   {
    "code": 0,
    "msg": "",
    "count": 53454 
    "data": [{
        "id": 1,
        "title": "title1 content",
        "time": 1510363800000
    }, {
        "id": 2,
        "title": "title2 content",
        "time": 1510212370000
    }, {
        "id": 3,
        "title": "title3 content",
        "time": 1510212370000
    }]
   }
