//动态引入组件，直接写（）=》import('组件地址') 这样是不可行的
const modules = import.meta.glob([

// 递归函数来生成路由，根据接口生成路由
function generateRoutes(routes: any[]): any {

//判断是否加载过动态路由，可以放在store中

  }

  if (!useToken().getToken()) {
    //你的逻辑
  } else if (!registerRouteFresh) {
   //修改以后的权限，刷新网页及时生效、vue3只支持单个路由添加，只能循环去动态加载路由
    await menuStore.getMenus(useUserInfoStore().userInfo.role)
    await menuStore.getBtn(useUserInfoStore().userInfo.role)
    const menus = menuStore.menu
    if (menus !== null && menus.length > 0) {
      const asyncRoutes = generateRoutes(menus)
      asyncRoutes.forEach((item: any) => {
        router.addRoute(item)
        // @ts-ignore
        //这个是我左侧菜单需要循环二级路由添加的，vue3addRoute以后router.options.routes是没有动态更新的
        router.options.routes.push(item)
      })
    }
    registerRouteFresh = true
    next({ ...to, replace: true })

总结：vue3权限控制动态路由踩坑记录，重点全在这里了
