vue2 利用网络代理axios实现前端跨域
vue.config.js 配置代理

module.exports = {devServer: {proxy: {'/CorsDemo': {target: 'http://xxxtech.net/', //需要跨域的地址changeOrigin: true,pathRewrite: {"^/CorsDemo": "/",//重写匹配的字段。把/CorsDemo转为 /}},}},}

vue文件

import axios from 'axios'methods:{
functionA (){
axios.get('/CorsDemo/validate?service=' + '123').then(response => {console.log(response)},error => {'请求失败',error.message})}}

实现开发环境跨域请求
