参照了别人写的记录一下
最新的vue里dev-server.js被替换成了webpack-dev-conf.js
在模拟后台数据的时候直接在webpack-dev-conf.js文件中修改
第一步,在const portfinder = require(‘portfinder’)后添加
//第一步
const express = require('express')
const app = express()//请求server
var appData = require('../data.json')//加载本地数据文件
var seller = appData.seller//获取对应的本地数据
var goods = appData.goods
var ratings = appData.ratings
var apiRoutes = express.Router()
app.use('/api', apiRoutes)//通过路由请求数据
第二步:找到devServer,在里面加上before()方法
devServer: {
clientLogLevel: 'warning',
historyApiFallback: true,
hot: true,
compress: true,
host: HOST || config.dev.host,
port: PORT || config.dev.port,
open: config.dev.autoOpenBrowser,
overlay: config.dev.errorOverlay
? { warnings: false, errors: true }
: false,
publicPath: config.dev.assetsPublicPath,
proxy: config.dev.proxyTable,
quiet: true, // necessary for FriendlyErrorsPlugin
watchOptions: {
poll: config.dev.poll,
},
//第二步找到devServer,在里面添加
before(app) {
app.get('/api/seller', (req, res) => {
res.json({
errno: 0,
data: seller
})//接口返回json数据,上面配置的数据seller就赋值给data请求后调用
}),
app.get('/api/goods', (req, res) => {
res.json({
errno: 0,
data: goods
})
}),
app.get('/api/ratings', (req, res) => {
res.json({
errno: 0,
data: ratings
})
})
}
}
提供一个json.data数据

PS:
所有的修改配置都需要重新启动运行命令的:npm run dev才能生效(很重要,否则无法请求到数据)
