{path: '/home',component: Home,redirect:'/home/index',children: [{path: 'index',component: MyHome},{path: 'self_test',component: SelfTest},{path: 'owm_info',component: OwnInfo},]},{path: '/testing',component: Testing},我从/home/self_test进入到testing路由 是可以的 然后再从/testing路由返回到/home/self_test路由  地址栏路径瞬间变成了/index  有没有哪位大佬 可以解答一下  万分感谢404s will fallback to /index.html
