首先在终端下载axios

npm install axios -s

在src文件下新建文件

axios.js内容

import axios from 'axios'
// import { ElMessage } from 'element-plus'
// import router from '../router'
import NProgress from 'nprogress'
import 'nprogress/nprogress.css'

axios.defaults.baseURL = process.env.NODE_ENV === 'production' ? process.env.API_ROOT : '';
axios.defaults.withCredentials = true
axios.defaults.headers['X-Requested-With'] = 'XMLHttpRequest'
axios.defaults.headers['token'] = localStorage.getItem('token') || ''
axios.defaults.headers.post['Content-Type'] = 'application/json'

NProgress.inc(0.2)
NProgress.configure({ easing: 'ease', speed: 600, showSpinner: false })

axios.interceptors.request.use(function (config) {
    // 启动进度条
    NProgress.start()
    // ElMessage.success({
    //     message: '成功',
    //     type: 'success'
    //   });
    return config
}, function (error) {
    // 对响应错误做点什么
    return Promise.reject(error);
    })

axios.interceptors.response.use(function (response) {
    // 对响应数据做点什么
    NProgress.done()
    return response;
    }, function (error) {
    // 对响应错误做点什么
    return Promise.reject(error);
    });


export default axios

之后再根目录新建vue.config.js引入mock数据

vue.config.js内容

const userData = require('./mock/modules/sum.json');
const address = require('./mock/modules/address_table.json');
module.exports = {
  publicPath: './',
    outputDir: "dist",
    devServer: {
        port:4000,
        open:true,
        before(app){
          app.get('/sum/list',(req,res,next)=>{
            res.json(userData);
          })
          app.get('/address/list',(req,res,next)=>{
            res.json(address);
          })
        },
      }

}

根目录下mock文件

mock文件下的index.js内容

// 首先引入Mock
const Mock = require('mockjs');

// 设置拦截ajax请求的相应时间
Mock.setup({
  timeout: '200-600'
});

let configArray = [];

// 使用webpack的require.context()遍历所有mock文件
const files = require.context('.', true, /\.js$/);
files.keys().forEach((key) => {
  if (key === './index.js') return;
  configArray = configArray.concat(files(key).default);
});

// 注册所有的mock服务
configArray.forEach((item) => {
  for (let [path, target] of Object.entries(item)) {
    let protocol = path.split('|');
    Mock.mock(new RegExp('^' + protocol[1]), protocol[0], target);
  }
});

mock文件下的address_table.json内容

{
    "address":{
        "status":200,
        "result":[
            {
                "ip_name": "dev_3011",
                "ip_address": "30.0.11.0/24",
                "progress": 50,
                "color": "red",
                "used":"10",
                "brand":"20"
              },
              {
                "ip_name": "dev_3011",
                "ip_address": "30.0.11.0/24",
                "progress": 70,
                "color": "green",
                "used":"10",
                "brand":"20"
              },
              {
                "ip_name": "dev_3011",
                "ip_address": "30.0.11.0/24",
                "progress": 50,
                "color": "red",
                "used":"10",
                "brand":"20"
              }
        ]
    }
}

将axios引入vue文件中

import axios from "../utils/axios";

 mounted() {
    this.getTabelInfo()
  },

methods: {
	getTabelInfo(){
           axios
        .get("/address/list")
        .then((res) => {
          this.tableData= res.data.address.result;
          console.log(res.data.address.result)
          this.$message.success("成功")
        })
        .catch((error) => {
          console.log(error);
          this.$message.error('失败')
        });
        },
}
