Vue introduces axios homologous cross-domain problem

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