vue引入axios同源跨域問題

 import axios from 'axios'
 export var baseurl = '/api'
 /**
 * Get請求
 */
 export function get(url, callback){
  console.log('測試get請求')
  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 {
