【Vue-Router】别名

后台返回来的路径名不合理，但多个项目在使用中了，不方便改时可以使用别名。可以有多个或一个。

First.vue

  <h1>First Secitonh1>

Second.vue，Third.vue代码同理

UserSettings.vue

<template>
  <h1>UserSettingsh1>
  <router-link to="/settings/children1">children1router-link>
  <br />
  <router-link to="/settings/children2">children2router-link>

  <button @click="toBackPage">返回button>
  <hr>
  <router-view>router-view>
  <router-view name="a">router-view>
  <router-view name="b">router-view>
template> 

<script setup lang="ts">
import { useRouter } from 'vue-router';
const router = useRouter();
const toBackPage = () => {
  router.go(-1);

import First from '../components/First.vue'

export const router = createRouter({
  history: createWebHistory(),
  // alias 起别名，都可以访问同一页面
  alias: ['/user-settings', '/Settings'],
