官网: http://mockjs.com/

安装  npm  install  mockjs -D

steps1: main.js 文件引入

import '@/api/mock.js'

steps2: src/api/mock.js

import Mock from 'mockjs'
import homeApi from './mockData/home'
/**
 * 1.拦截的路径:mock拦截了正常NetWork/网络请求,数据正常响应
 * 2.方法
 * 3.制造假数据
 */
Mock.mock(/api\/home\/getTableData/, 'get', homeApi.getTableData)

steps3: 编造数据

src/api/mockData/home.js

export default {
  getTableData: () => {
    return {
      code: 200,
      data: {
        tableData: [
          {
            name: 'oppo',
            todayBuy: 500,
            monthBuy: 3500,
            totalBuy: 22000
          }
        ]
      }
    }
  }
}

steps4: 页面发起请求

import axios from 'axios'
axios({
  url: '/api/home/getTableData',
  method: 'get'
}).then((res) => {
  const data = res.data.getTableData
  if (data.code == 200) {
    tableData.value = data.data.tableData
  }
})
