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) }
