第一步安装mockjs:npm i mockjs -S

在src目录下新建mock文件夹，文件夹添加test.js

test.js内容如下：

import Mock from 'mockjs';const List = [];const count = 20;for (let i = 0; i < count; i++) {  List.push(Mock.mock({    id: '@id',    title: '@ctitle(10, 20)',    'status|1': ['published', 'draft'],    author: '@cname',    display_time: '@datetime',    pageviews: '@integer(300, 5000)'  }));}const nowPeople = {  "errcode": "0",  "errmsg": "success",  "data": {    "expo_audience": "@integer(100, 5000)",  }}const viewNumber = {  "errcode": "0",  "errmsg": "success",  "data": { "desk_num": 24, "desk_duration": 105.50, "per_desk_duration": 25.20 }}export let nowPeopleData = Mock.mock('http://compony.com/api/v1/t1', nowPeople);export let viewNumberData = Mock.mock('http://compony.com/api/v1/t2', viewNumber);

在main.js中引入：

import * as expo from './mock/test.js'

axios.defaults.baseURL = 'http://compony.com/api/v1'

在组件中使用：

this.axios.get('/t1').then((data) => {}

等到后台开发好api后，只需要注释掉import * as expo from './mock/test.js'即可，其他代码都不用动
