Uncaught (in promise) Error: timeout of 500ms exceeded

一、封装axios
在响应拦截器中处理超时

import router from '@/router'
import axios from 'axios'
import { Message } from 'sec-ui'

const api = axios.create({
  // baseURL: 'http://39.105.151.241:8081',
  timeout: 5 * 1000 // request timeout
})

api.defaults.timeout = 5000

api.interceptors.request.use(config => {
  // config.headers.Authorization = window.sessionStorage.getItem('tokense')
  return config
}, err => {
  Promise.reject(err)
})

// 响应拦截器
api.interceptors.response.use(res => {
  // console.log(res, '响应')
  const code = res.data.code
  switch (code) {
    case 401:
      router.push({path: '/'})
      break
    default:
      break
  }
  return Promise.resolve(res.data)
}, err => {
  // console.log(err, 'err')
  if (err.message.includes('timeout')) {
    Message({
      message: '请求服务超时:传输超时',
      type: 'error',
      duration: 5 * 1000
    })
  } else {
    if (err.response.status === 413) {
      Message({
        message: 'Request Entity Too Large',
        type: 'error',
        duration: 5 * 1000
      })
    } else {
      Message({
        message: err,
        type: 'error',
        duration: 5 * 1000
      })
    }
  }
  const res = ''
  console.log('err' + err)
  return res && Promise.reject(err)
})

export default api
