前言：
跨域方案有很多种，既然我们用到了Vue，那么就使用vue提供的跨域方案。
解决方案：
1.修改HttpRequestUtil.js
1 import axios from 'axios'2 3 export var baseurl = '/api'4 /**5 * Get请求6 */7 export function get(url, callback){8 console.log('测试get请求')9 axios.get(baseurl+url)10 .then(function (response) {11 console.log(response)12 callback(response.data,true)13 })14 .catch(function (error) {15 console.log(error)16 callback(null,false)17 })18 }19 20 21 export default {22 get23 }复制代码 2.修改index.js
