vue + webpack 模拟后台数据

一、在webpack-dev-conf.js文件中：

1、在const portfinder = require(‘portfinder’)后添加如下内容

const express = require('express')
const app = express() //请求server
var appData = require('../mock/goods.json') //加载本地数据文件
var apiRoutes = express.Router()
app.use(apiRoutes) //通过路由请求数据

2、找到devServer,在里面加上before（）方法

devServer: {
    clientLogLevel: 'warning',
    historyApiFallback: {
        rewrites: [
            { from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, 'index.html') },
        ],
    },
    hot: true,
    contentBase: false, // since we use CopyWebpackPlugin.
    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,
    },
    before(app) {
        app.get('/goods', (req, res) => {
            res.json(appData)
        })
    }
},

二、在goods.json文件：

{
    "status": "0",
    "msg": "",
    "result": [
        {
            "productId": "100001",
            "productName": "小米6",
            "productPrice": "2499",
            "productImg": "1.jpg"
        },{
            "productId": "100002",
            "productName": "音箱",
            "productPrice": "999",
            "productImg": "2.jpg"
        },{
            "productId": "100003",
            "productName": "电脑",
            "productPrice": "199",
            "productImg": "3.jpg"
        }
    ]
}

三、在GoodsList.vue文件中：
