• 调用某接口，发现token需要更新，response.config记录着我们上一次请求的结果
      1. http.interceptors.response.use(async response => {
      2.   localStorage.setItem('token', response.data.refreshToken)
      3.   let refreshRequest = () => {
      4.     return new Promise((resolve, reject) => {
      5.       http(response.config).then(data => {
      6.         resolve(data)
      7.       }).catch((e) => {
      8.         reject(e)
      9.       })
      10.     })
      11.   }
      12.   let res = await refreshRequest()
      13.   return Promise.resolve(res)
      14. })
