1.配置 build/webpack.dev.conf.js

// 获取静态json数据 const express = require('express') const app = express() const apiServer = express() const bodyParser = require('body-parser') apiServer.use(bodyParser.urlencoded({ extended: true })) apiServer.use(bodyParser.json()) const apiRouter = express.Router() const fs = require('fs') apiRouter.route('/:apiName') .all(function (req, res) { fs.readFile('./db.json', 'utf8', function (err, data) { if (err) throw err var data = https://www.it610.com/article/JSON.parse(data) if (data[req.params.apiName]) { res.json(data[req.params.apiName]) } else { res.send('no such api name') }}) })apiServer.use('/api', apiRouter); apiServer.listen(8081, function (err) { if (err) { console.log(err) return } console.log('Listening at http://localhost:' + (8081) + '\n') })

【vue2.5.2通过http请求获取静态的json数据】2.新建 db.json

{ "getNewsList": [ { "id": 1, "title": "新闻条目1新闻条目1新闻条目1新闻条目1", "url": "http://starcraft.com" }, { "id": 2, "title": "新闻条目2新闻条目2新闻条目2新闻条目2", "url": "http://warcraft.com" }, { "id": 3, "title": "新闻条3新闻条3新闻条3", "url": "http://overwatch.com" }, { "id": 4, "title": "新闻条4广告发布", "url": "http://hearstone.com" } ], "login": { "username": "yudongdong", "userId": 123123 }, "getPrice": { "amount": 678 }, "createOrder": { "orderId": "6djk979" }, "getOrderList": { "list": [ { "orderId": "ddj123", "product": "数据统计", "version": "高级版", "period": "1年", "buyNum": 2, "date": "2016-10-10", "amount": "500元" }, { "orderId": "yuj583", "product": "流量分析", "version": "户外版", "period": "3个月", "buyNum": 1, "date": "2016-5-2", "amount": "2200元" }, { "orderId": "pmd201", "product": "广告发布", "version": "商铺版", "period": "3年", "buyNum": 12, "date": "2016-8-3", "amount": "7890元" } ] } }

3.通过 localhost:8081/api/getNewsList 访问
4.在页面中获取的方式

export default { data() { newsList: [] }, created: function(){ this.$http.get('api/getNewsList').then((res)=> { this.newsList = res.data },(err)=> { console.log(err); }) } }
