json-server实现数据Mock

1. 项目中安装json-server

npm i -D json-server --legacy-peer-deps

2. 准备一个json文件

建立一个server文件夹，建立一个data.json文件。
以下为一个例子：

{"ka": [{"type": "pay","money": -99,"date": "2022-10-24 10:36:42","useFor": "drinks","id": 1},{"type": "pay","money": -88,"date": "2022-10-24 10:37:51","useFor": "longdistance","id": 2},{"type": "income","money": 100,"date": "2022-10-22 00:00:00","useFor": "bonus","id": 3},{"type": "pay","money": -33,"date": "2022-09-24 16:15:41","useFor": "dessert","id": 4},{"type": "pay","money": -56,"date": "2022-10-22T05:37:06.000Z","useFor": "drinks","id": 5},{"type": "pay","money": -888,"date": "2022-10-28T08:21:42.135Z","useFor": "travel","id": 6},{"type": "income","money": 10000,"date": "2023-03-20T06:45:54.004Z","useFor": "salary","id": 7},{"type": "pay","money": -10,"date": "2023-03-22T07:17:12.531Z","useFor": "drinks","id": 8},{"type": "pay","money": -20,"date": "2023-03-22T07:51:20.421Z","useFor": "dessert","id": 9},{"type": "pay","money": -100,"date": "2023-03-22T09:18:12.898Z","useFor": "drinks","id": 17},{"type": "pay","money": -50,"date": "2023-03-23T09:11:23.312Z","useFor": "food","id": 18},{"type": "pay","money": -10,"date": "2023-04-03T11:14:56.036Z","useFor": "food","id": 19}]}

3. 添加启动命令

在package.json文件中添加：

"server": "json-server ./server/data.json --port 8888"

4. 访问接口进行测试
