在router/index.js

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login.vue'
import Home from '@/components/Home.vue'

Vue.use(Router)

const router = new Router({
  routes: [

    {path: '/', redirect: '/login'},
    {path: '/Login', component: Login},
    {path: '/Home', component: Home}
  ]
})

router.beforeEach((to, from, next) => {
  if (to.path != '/login') {
    if (!window.sessionStorage.getItem("token")) {
      next({
        path: '/login'
      })
    } else {
      next()
    }
  } else {
    next()
  }
})

export default router
