// router/index.js
import { createRouter, createWebHistory } from 'vue-router'
import Home from '../views/Home.vue'
import About from '../views/About.vue'

const routes = [
  {
    path: '/',
    name: 'Home',
    component: Home
  },
  {
    path: '/about',
    name: 'About',
    component: About
  }
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

router.beforeEach((to, from, next) => {
  // 在这里处理路由跳转时的参数传递
  console.log('跳转前的参数：', to.params)
  next()
})

export default router

<!-- views/Home.vue -->
<template>
  <div>
    <h1>首页</h1>

  </div>
</template>
