Vue.js 在 beforeEach 期间将 vuex 模块状态传递给 vuerouter

我将VueJS与vuex和vue-router结合使用.我有一个vuex模块正在对其存储进行变异，并试图使用它来确定用户是否经过身份验证.

下面是我的代码在相关部分的样子.

main.js

import Vue from 'vue'
import App from './App.vue'
import store from './store'
import router from './router'

router.beforeEach((to, from, next) => {
    console.log(router.app) // prints a Vue$2 object
    console.log(router.app.$store) // undefined
    console.log(store.getters.isAuthenticated) // false
    ...
}

const app = new Vue({
  store,
  router,
  ...App
})

app.$mount('#app')

/store/index.js

import Vue from 'vue'
import Vuex from 'vuex'
import core from './modules/core'

Vue.use(Vuex)

const store = new Vuex.Store({
  modules: {
    core: core
  }
})

export default store

/store/modules/core.js

import * as types from '../types'
import api from '../../api'
import router from '../../router'

const state = {
  token: null,
  user: null,
  authenticated: false
}

const mutations = {
  [types.LOGIN_SUCCESS] (state, payload) {
    console.log('mutate')
    state.token = payload.token
    state.user = payload.user
    state.authenticated = true
    router.go('/')
  }
}

const getters = {
  isAuthenticated: state => {
    return state.authenticated
  }
}

const actions = {
  [types.LOGIN] (context, payload) {
    api.getToken(payload).then(response => {
      context.commit(types.LOGIN_SUCCESS, response)
    })
  }
}

export default {
  state,
  mutations,
  actions,
  getters
}

当我通过逻辑触发LOGIN操作时，我可以看到Mutations 正确执行，当我使用Chrome扩展查看core模块的vuex状态时，user和authenticated的状态已经正确Mutations .

QUESTION

似乎路由在.beforeEach环路中运行时，这个模块还没有加载.这是真的吗？

如果是，关于如何处理这种情况，还有哪些其他建议？
