vue 添加子路由，并对路由重定向

// 用户信息首页
    {
      path: '/user/index',
      name: 'userIndex',
      component: userIndex,
      redirect: '/user/index/show',
      children: [
          //个人信息展示
        {
          path: 'show',
          name: 'userInformShow',
              component: InformShow
        },
        //个人信息展示-提升
    {
        path: 'improve',
        name: 'userInformImprove',
        component: InformImprove
    }
  ]
}
