How to deal with axios errors

This time I will show you how to deal with axios errors and what are the precautions for dealing with axios errors. The following is a practical case, let's take a look.

Now the official package of vue no longer updates vue-resource, and instead recommends axios. The following is the axios plug-in setting summarized in the actual project:

/**
 * @file Axios的Vue插件（添加全局请求/响应拦截器）
 */
// https://github.com/mzabriskie/axios
import axios from 'axios'
// 拦截request,设置全局请求为ajax请求
axios.interceptors.request.use((config) => {
 config.headers['X-Requested-With'] = 'XMLHttpRequest'
 return config
})
// 拦截响应response，并做一些错误处理
axios.interceptors.response.use((response) => {
 const data = response.data
// 根据返回的code值来做不同的处理（和后端约定）
 switch (data.code) {
 case '0':
  // 举例
  // exp: 修复iPhone 6+ 微信点击返回出现页面空白的问题
  if (isIOS()) {
  // 异步以保证数据已渲染到页面上
  setTimeout(() => {
   // 通过滚动强制浏览器进行页面重绘
   document.body.scrollTop += 1
  }, 0)
  }
  // 这一步保证数据返回，如果没有return则会走接下来的代码，不是未登录就是报错
  return data
 // 需要重新登录
 case 'SHIRO_E5001':
  // 微信生产环境下授权登录
  if (isWeChat() && IS_PRODUCTION) {
  axios.get(apis.common.wechat.authorizeUrl).then(({ result }) => {
   location.replace(global.decodeURIComponent(result))
  })
  } else {
  // 否则跳转到h5登录并带上跳转路由
  const search = encodeSearchParams({
   next: location.href,
  })
  location.replace(`/user/login?${search}`)
  }
  // 不显示提示消息
  data.description = ''
  break
 default:
 }
 // 若不是正确的返回code，且已经登录，就抛出错误
 const err = new Error(data.description)
 err.data = data
 err.response = response
 throw err
}, (err) => { // 这里是返回状态码不为200时候的错误处理
 if (err && err.response) {
 switch (err.response.status) {
  case 400:
  err.message = '请求错误'
  break
  case 401:
  err.message = '未授权，请登录'
  break
  case 403:
  err.message = '拒绝访问'
  break
  case 404:
  err.message = `请求地址出错: ${err.response.config.url}`
  break
  case 408:
  err.message = '请求超时'
  break
  case 500:
  err.message = '服务器内部错误'
  break
  case 501:
  err.message = '服务未实现'
  break
  case 502:
  err.message = '网关错误'
  break
  case 503:
  err.message = '服务不可用'
  break
  case 504:
  err.message = '网关超时'
  break
  case 505:
  err.message = 'HTTP版本不受支持'
  break
  default:
 }
 }
 return Promise.reject(err)
})
axios.install = (Vue) => {
 Vue.prototype.$axios = axios
}
export default axios
