vue-cli项目如何使用vue-resource获取本地的json数据（模拟服务端返回数据）

{
 "seller": {
   "name": "粥品香坊（回龙观）",
   "description": "蜂鸟专送",
   "bulletin": "会指定餐饮服务商。",

 },
 "goods": [
   {
    "name": "热销榜",
    "type": -1
   },
   {
    "name": "热销榜",
    "type": -1
   }
 ],
 "ratings": [
  {
   "username": "3******c",
   "avatar": "http://static.galileo.xiaojukeji.com/static/tms/default_header.png",
   "recommend": [
    "南瓜粥",
    "皮蛋瘦肉粥"
   ]
  },
