request.js

import axios from 'axios'
import store from '../store'
import qs from 'qs'

export const http = axios.create({
  baseURL: 'http://localhost:8000/api/',
  header: {
    'Content-Type': 'application/x-www-form-urlencoded'
  }
})
http.interceptors.response.use(function (response) {
  return response
}, function (error) {
  const originalRequest = error.config
  console.log(originalRequest)  
  if (error.response.status === 401 && !originalRequest._retry) {
    originalRequest._retry = true
    //get refresh token
    const refreshToken = store.getters['userInfo/getOauth2'].refresh_token
    //make refresh token request
    return http.post(
      http.defaults.baseURL + 'refreshtoken',
      qs.stringify({username: store.getters['userInfo/getUser'].username, grant_type: 'refresh_token', refresh_token: refreshToken}),
      {
        auth: {
          username: 'web-application-manager',
          password: '6cd316c28d8456b9fd7577cc03acfd5f029b9068'
        }
      })
      .then((responseData) => {
        // set new oauth2 info
        store.dispatch('userInfo/set', responseData.data)
        http.defaults.headers.common['Authorization'] = 'Bearer ' + store.getters['userInfo/getOauth2'].access_token
        originalRequest.headers['Authorization'] = 'Bearer ' + store.getters['userInfo/getOauth2'].access_token
        //retry failed request
        return http(originalRequest)
      }).catch(function (error) {
        console.log(error)
      })
  }

  return Promise.reject(error)
})
