json-server，模拟rest接口，自动生成增删改查接口。(官网地址：json-server - npm)
使用方法：
1. 安装json-server，npm i json-server -g
2. 创建json文件，文件中存储list数据，db.json
{"posts": [{ "id": "1", "title": "a title", "views": 100 },{ "id": "2", "title": "another title", "views": 200 }],"comments": [{ "id": "1", "text": "a comment about post 1", "postId": "1" },{ "id": "2", "text": "another comment about post 1", "postId": "1" }],"profile": {"name": "typicode"}
}3. 启动 json-server
终端进入到db.json所在目录，执行 npx json-server db.json 命令启动服务
注意：如果遇到下面报错，需要升级node版本
PS D:\workspace\learnui\vuex-demo\db> npx json-server index.json
