Javascript-Vue-Router：页面刷新后查看返回登录页面

我正在使用Vuejs构建应用程序,并使用vue-router和vuex.我现在卡住了,因为在用户登录后,我的应用程序重定向到了仪表板,但是如果我刷新页面,他将再次返回登录页面.为了验证用户是否被登录,我的应用检查本地存储是否具有access_token,然后将其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 /路由器

index.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 }
   }
 ]

解决方法:

您将需要使isLogged函数在刷新时知道本地存储情况.

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
)
