详解vue-cli项目中怎么使用mock数据

{
 "code": 200,
 "data": [
 {
  "id": 0,
  "title": "复联3大陆定档5月11日，全球最晚!!"
 },
 {
  "id": 1,
  "title": "蚁人2最新预告发布，展现量子领域!!"
 }
 ]
}

{
 "code": 200,
 "data": [
 {
  "id": 0,
  "nickname": "美国队长",
  "avatar": "url"
 },
 {
  "id": 1,
  "nickname": "惊奇队长",
  "avatar": "url"
 }
 ]
}

// mock code
const express = require('express')
const app = express()
const posts = require('../mock/posts.json') // 文章列表数据源
const users = require('../mock/users.json') // 用户列表数据源
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/posts', (req, res) => {
  res.json(posts)
 })
 app.get('/api/users', (req, res) => {
  res.json(users)
 })
 }
}

import axios from 'axios'
Vue.prototype.$http = axios

created() {
 this.$http.get("http://localhost:8080/api/posts").then(res => {
 console.log(res.data)
 })
}
