导航守卫

可以在路由的meta属性中配置自定义属性：
  {
    path: '/about',
    name: 'About',
    meta: {
      title: 'about'
    },
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
  }


const router = new VueRouter({
  mode: 'history',
  routes,
})

router.beforeEach((to, from, next) => {
  document.title=to.meta.title;
  next();
})
