nuxt中使用路由守卫的方法步骤

import { getCookie, setCookie } from '@/pages/logreg/api/cookie'
import axios from 'axios'

export default ({ app, store }) => {
 app.router.beforeEach((to, from, next) => {
  let isClient = process.client
  if (isClient) {
   let currentUrl = location.href
   if (currentUrl.indexOf('access_token=') !== -1) {
    let wechattoken = currentUrl.split('access_token=')[1]
    wechattoken = wechattoken.split('&')[0]
    setCookie('token', wechattoken, 5)
   }
   let token = getCookie('token')
   if (token) {
    store.state.user.userinfo.token = token
    axios
     .get('https://api.ass.net/pub/api/user_info', {
      params: {
       token
      }
     })
     .then(res => {
      res = res.data
      if (res.code == 0) {
       res = res.data
       res.headImg = res.headImg.replace('http:', 'https:')
       store.state.user.userinfo = Object.assign(
        {},
        store.state.user.userinfo,
        res
       )
      }
     })
     .catch(error => console.log(error))
   }
  }
  next()
 })
}

 plugins: [
  { src: '@/plugins/route', ssr: true }
 ],

let myredirect;
export default function ({redirect }) {
 myredirect = redirect;
}

if (error.message.toString().slice(-3) === '401') {
  Vue.prototype.$message.error('登陆超时，请重新登陆...')
  setTimeout(function () {
   return myredirect('/login/login')
  }, 2000)
 }
