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)
 }
