  // 2. 定义一些路由
  // 每个路由都需要映射到一个组件。
  // 我们后面再讨论嵌套路由。

        name: 'about',

    },
    { path: '/user/:id', component: User },
    {
        name: "news",
        //path: '/news/:id(\\d+)',//正则匹配
        // path: '/news/:id+',//多个参数
        //path: '/news/:id+',//参数可有可无
        //path: '/news/:id*',//参数可重复叠加
        path: '/news/:id?',//参数不可重复叠加
        component: News
    },
    {
        path: '/:path(.*)',
        component: NotFound
    },//使用正则，匹配任意path
    {
        path: "/parent",
        // alias: '/father', //起一个别名
        alias: ['/father', '/laofuqin'], //起多个别名

  // 3. 创建路由实例并传递 `routes` 配置
  // 你可以在这里输入更多的配置，但我们在这里
  // 暂时保持简单
  const router = createRouter({
    // 4. 内部提供了 history 模式的实现。为了简单起见，我们在这里使用 hash 模式。
    history: createWebHashHistory(),
    routes, // `routes: routes` 的缩写
  })
  
  
  export default router
