route中的to.matched的运用

routes:
[
   {
      path: ‘/cinema‘,
      redirect: ‘/page/cinema‘,
      component: BlankLayout,
      meta: { title: ‘影院‘ , requiresAuth: true}
      children: [
        {
          path: ‘/cinema/plan‘,
          name: ‘cinemaPlan‘,
          component: () => import(‘./views/cinema/Plan‘),
          meta: { title: ‘影院排期‘ }
        },
        {
          path: ‘/cinema/cinemaDetail‘,
          name: ‘cinemaDetail‘,
          component: () => import(‘./views/cinema/CinemaDetail‘),
          meta: { title: ‘影院详情‘ }
        }
       ]
    }
]

to.meta && (typeof to.meta.title !== ‘undefined‘ && setDocumentTitle(`${to.meta.title}`))
  if (to.matched.some(record => record.meta.requiresAuth)) {
    // this route requires auth, check if logged in
    // if not, redirect to login page.
    if (!store.getters.token) {
      next({
        path: ‘/login‘,
        query: { redirect: to.fullPath }
      })
    } else {
      if (to.query.siteCode) {
        next()
        return
      }
      if (from.query.siteCode) {
        const query = JSON.parse(JSON.stringify(to.query))
        query.siteCode = from.query.siteCode
        next({
          path: to.path,
          query: query
        })
      } else {
        next() // 确保一定要调用 next()
      }
    }
