下面的函數(shù) 用 async函數(shù) 該如何寫，請指教

  methods: {
    getList() {
      this.listLoading = true
      fetchList(this.listQuery).then(response => {
        this.list = response.data.items
        this.total = response.data.total
        // Just to simulate the time of the request
        setTimeout(() => {
          this.listLoading = false
        }, 1.5 * 1000)
      })
    },

//fetchList
export function fetchList(query) {
  return request({
    url: '/article/list',
    method: 'get',
    params: query
  })
}

//request
import axios from 'axios'
import { Message } from 'element-ui'
import store from '@/store'
import { getToken } from '@/utils/auth'

// create an axios instance
const service = axios.create({
  baseURL: process.env.BASE_API, // api的base_url
  timeout: 5000 // request timeout
})

// request interceptor
service.interceptors.request.use(config => {
  // Do something before request is sent
  if (store.getters.token) {
    // 讓每個請求攜帶token-- ['X-Token']為自定義key 請根據(jù)實際情況自行修改
    config.headers['X-Token'] = getToken()
  }
  return config
}, error => {
  // Do something with request error
  console.log(error) // for debug
  Promise.reject(error)
})

// respone interceptor
service.interceptors.response.use(
  response => response,
  error => {
    console.log('err' + error) // for debug
    Message({
      message: error.message,
      type: 'error',
      duration: 5 * 1000
    })
    return Promise.reject(error)
  })

export default service
