在config index.js文件中
引入如下代码即可
const path = require('path')
const devEnv = require('./dev.env')
module.exports = {dev: {// PathsassetsSubDirectory: 'static',assetsPublicPath: '/',proxyTable: devEnv.OPEN_PROXY === false ? {} : {'/api': {target: 'http://localhost:8083',changeOrigin: true,pathRewrite: {'^/api': '/'}}},
// PathsassetsSubDirectory: 'static',assetsPublicPath: '/',proxyTable: devEnv.OPEN_PROXY === false ? {} : {'/api': {target: 'http://localhost:8083', //需要更改的后端的端口号changeOrigin: true,pathRewrite: {'^/api': '/'}}},这里的配置是正则表达式,以/api开头的将会被用用‘/api'替换掉,假如后台文档的接口是 /api/list/xxx//前端api接口写:axios.get('/api/list/xxx') , 被处理之后实际访问的是:http://news.baidu.com/api/list/xxx}}},
