vue router 关于权限的全局路由守卫（无token）

前提：由于公司架构师整合，决定将用户token放跨域cookie里面(axios设置withCredentials: true)，前端就无需记录token与用户状态，由此对全局路由的逻辑的改变
关键：
用 【用户信息】判断用户是否登录，
没有用户信息时，获取用户信息（若已登录获取成功，没有登录或失效获取不到用户信息），
然后再进入下一个路由

import router from './router'
import store from './store'
import NProgress from 'nprogress' // progress bar
import 'nprogress/nprogress.css' // progress bar style
import getPageTitle from '@/utils/get-page-title'

NProgress.configure({ showSpinner: false }) // NProgress Configuration

const whiteList = ['/loginBms'] // no redirect whitelist

router.beforeEach(async(to, from, next) => {
  // start progress bar
  NProgress.start()
  // set page title
  document.title = getPageTitle(to.name)

  // determine whether the user has logged in
  const hasUserInfo = store.state.bmsUser.name
  if(hasUserInfo){
    if(to.path === '/loginBms'){
      next({ path: from.path })
      NProgress.done()
      return false
    }
    next()
  }else{
    if(whiteList.includes(to.path)){
      next()
      return false
    }
    try {
      await store.dispatch('bmsUser/getUserInfo')
      const accessRoutes = await store.dispatch('bmsPermission/generateRoutes')
      console.log('accessRoutes:',accessRoutes)
      router.addRoutes(accessRoutes)
      next({ ...to, replace: true })
    } catch (error) {
      next(`/loginBms?redirect=${to.path}`)
      NProgress.done()
    }
  }
})

router.afterEach(() => {
  // finish progress bar
  NProgress.done()
})
