router.js

import Vue from 'vue'import Router from 'vue-router'Vue.use(Router)export default new Router({  mode:'history',  base:__dirname,  routes: [    {path:'/'},    {path:'/params/:aaa/:bbb'},    {path:'/params-regex/:id(\\d+)'}  ]})

在vue中冒号( : )指代绑定的意思，路径path中参数可以使用正则进行匹配，如上述id(\\d+)只能识别数字，如果传入参数非数字，则params中不会有id参数
App.vue

<template>  <div id="app">    <h1>路由url传值</h1>    <ul>      <li><router-link to="/">/</router-link></li>      <li><router-link to="/params/111/222">/params/111/222</router-link></li>      <li><router-link to="/params-regex/333">/params-regex/333</router-link></li>    </ul>    <p>Show</p>    <pre>      <code>        {{ JSON.stringify($route,null,2) }}      </code>    </pre>  </div></template>

npm run dev 运行项目

结果为：

• /params/111/222
• /params-regex/333
