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

 import axios from 'axios'
 export var baseurl = '/api'
 /**
 * Get请求
 */
 export function get(url, callback){
 console.log('测试get请求')
 axios.get(baseurl+url)
 .then(function (response) {
 console.log(response)
 callback(response.data,true)
 })
 .catch(function (error) {
 console.log(error)
 callback(null,false)
 })
 }
 export default {
 get
 }

2.修改index.js

'use strict'
 // Template version: 1.3.1
 // see http://vuejs-templates.github.io/webpack for documentation. 
 const path = require('path') 
 module.exports = {
 dev: {
 // Paths
 assetsSubDirectory: 'static',
 assetsPublicPath: '/',
 proxyTable: {
 '/api': {
 target: 'http://127.0.0.1:8088',//设置你调用的接口域名和端口号 别忘了加http
 changeOrigin: true,
 pathRewrite: {
 '^/api': 'http://127.0.0.1:8088'//这里理解成用‘/api'代替target里面的地址，后面组件中我们掉接口时直接用api代替 比如我要调用'http://40.00.100.100:3002/user/add'，直接写‘/api/user/add'即可
 }
 }
 },
 // Various Dev Server settings
 host: 'localhost', // can be overwritten by process.env.HOST
 port: 8090, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
 autoOpenBrowser: false,
 errorOverlay: true,
 notifyOnErrors: true,
 poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-

 cacheBusting: true,

 },
 build: {
 // Template for index.html

 // Run the build command with an extra argument to

 }
 }

proxyTable: {
'/api' : {
target: 'http://127.0.0.1:8088' , //设置你调用的接口域名和端口号 别忘了加http
changeOrigin: true ,
pathRewrite: {

}
