--------------------

1：在项目里面新建一个mock文件夹，在mock文件夹里面新建一个test.json文件

![1ce582489e1100782ec2b6ed9f00203d.png][]  
test.json:

{
        "first":[
    
            {"name":"520","nick":"我爱你"},
    
            {"name":"521","nick":"我愿意"},
    
            {"name":"1314","nick":"一生一世"}
        ]
    
    }

2:在build目录下找到webpack.dev.conf.js文件，编写以下代码

// mock code
    const express = require('express')
    const app = express()
    const posts = require('../mock/test.json') 
    const routes = express.Router()
    app.use('/api', routes)
    
    // 如果是post请求，那么将get改为post即可
    devServer: {
     ...
     before(app){
     app.get('/api/test', (req, res) => {
      res.json(posts)
     })
    
     }
    }

3:浏览器输入http://localhost:8080/api/test  
成功看到模拟数据

4:使用第三方http请求库axios进行ajax请求,这里不会，可以从参考上一篇文章内容。

methods: {
                getData() {
                    axios.get('http://localhost:8080/api/test').then(response => {
                        console.log(response.data);
                    }, response => {
                        console.log("error");
                    });
                }
            }

vue页面代码参考

<template>
        <div id="app">
        </div>
    </template>
    <script>
        import axios from "axios";
        export default {
            name: "app",
            data() {
                return {
                    itemList: []
                }
            },
            mounted() {
                this.getData();
            },
            methods: {
                getData() {
                    axios.get('http://localhost:8080/api/test').then(response => {
                        console.log(response.data);
                    }, response => {
                        console.log("error");
                    });
                }
            }
        }
    </script>

5:在浏览器里面，我们可以看到，mock里面的数据请求成功显示如下
