Vue-Router：页面刷新后视图返回登录页面

Question

我正在使用 Vuejs 并使用 vue-router 和 vuex 构建一个应用程序。我现在陷入困境，因为在用户登录后，我的应用程序重定向到仪表板，但如果我刷新页面，他会再次返回登录页面。为了验证用户是否已登录，我的应用程序检查本地存储是否有 access_token，然后将他重定向到路由器视图“/”。

这是我的路由器文件夹和他的文件：

src/router

索引.js：

import Vue from 'vue'

import VueRouter from 'vue-router'

import {routes} from './routes'

import beforeEach from './beforeEach'

Vue.use(VueRouter)

const router = Vue.router = new VueRouter({
  hashbang: false,
  linkActiveClass: 'active',
  saveScrollPosition: true,
  mode: 'history',
  base: __dirname,
  routes
})


router.beforeEach(beforeEach)

export default router

beforeEach.js：

import store from '../store/store'

const isAuthRoute = route => route.path.indexOf('/login') !== -1

const isLogged = () => store.getters.isLoggedIn

export default (to, from, next) => {
  if (!isAuthRoute(to) && !isLogged()) {
    next('/login')
  } else {
    next()
  }
}

路线：

export const routes = [
   {
     path: '/',
     component: require('../components/Application/Dashboard.vue'),
     meta: { auth: true },
     children: [
       {
         path: '',
         component: require('../components/Home.vue'),
         name: 'home',
         meta: { auth: true }
       },
       {
         path: 'account',
         component: require('../components/Application/Account.vue'),
         name: 'account',
         meta: { auth: true }
       }
     ]
   },
   {
     path: '/login',
     component: require('../components/Application/Login.vue'),
     name: 'login',
     meta: { auth: false }
   },
   {
     path: '*',
     component: require('../components/PageNotFound.vue'),
     meta: { auth: false }
   }
 ]

您需要使 isLogged 函数了解刷新时的本地存储情况。

const isLogged = () => storeLoggedIn || loadSessionFromLocalStorage
const storeLoggedIn = () => store.getters.isLoggedIn
const loadSessionFromLocalStorage = () => (
  // if localstorage has token
  //   commit a mutation for loggedIn and then return true
  // else return false
)
