【React】json-server

1.安装到开发环境

npm install json-server -D

2.在根目录下下，新建db.json文件

{
  "list": [
    {
      "rpid": 3,
      "user": {
        "uid": "13258165",
        "avatar": "http://toutiao.itheima.net/resources/images/98.jpg",
        "uname": "周杰伦"
      },
      "content": "哎哟，不错哦",
      "ctime": "10-18 08: 15",
      "like": 126
    },
    {
      "rpid": 2,
      "user": {
        "uid": "36080105",
        "avatar": "http://toutiao.itheima.net/resources/images/98.jpg",
        "uname": "许嵩"
      },
      "content": "我寻你千百度 日出到迟暮",
      "ctime": "11-13 11: 29",
      "like": 88
    },
    {
      "rpid": 1,
      "user": {
        "uid": "30009257",
        "avatar": "http://toutiao.itheima.net/resources/images/98.jpg",
        "uname": "黑马前端"
      },
      "content": "学前端就来黑马",
      "ctime": "10-19 09: 00",
      "like": 66
    }
  ]
}

3.在package.json中的script中，添加自定义命令

4.执行 npm run serve 就会执行后面的命令，以db.json为数据源，端口为3004开启一个服务
