vue3에서 동적으로 라우팅을 추가하는 방법

import {createRouter, createWebHashHistory} from "vue-router";
const  routes = [
    {
        path: "/",
        component: () => import("../views/HomePage.vue")
    },
    {
        path: "/404",
        component: () => import("../views/ErrorPage.vue")
    },
    {
        path: "/:catchAll(.*)", // 不识别的path自动匹配404
        redirect: '/404',
    },
]
const router=createRouter({
    history: createWebHashHistory(),
    routes
})
export default router;

import {useRouter} from "vue-router";
let router = useRouter();
function addRouter(){
  router.addRoute(  {
    path: "/vip",
    component: () => import("../views/VipPage.vue")
  })
}

router.addRoute({ name: 'admin', path: '/admin', component: Admin })
router.addRoute('admin', { path: 'settings', component: AdminSettings })

// 这等效于：
router.addRoute({
  name: 'admin',
  path: '/admin',
  component: Admin,
  children: [{ path: 'settings', component: AdminSettings }],
})
