动态匹配路由$route.params

      <router-link to="/user/3">User3</router-link>
      <router-link to="/register">Register</router-link>

      <!-- 路由占位符 -->

    <script>
      const User = {
        template: '<h1>User 组件 -- 用户id为: {{$route.params.id}}</h1>'
      }

      const Register = {
        template: '<h1>Register 组件</h1>'
      }

      // 创建路由实例对象
      const router = new VueRouter({
        // 所有的路由规则
        routes: [
          { path: '/', redirect: '/user'},
          { path: '/user/:id', component: User },
          { path: '/register', component: Register }
        ]
      })

      // 创建 vm 实例对象
      const vm = new Vue({
        // 指定控制的区域
        el: '#app',
        data: {},
        // 挂载路由实例对象
        // router: router
        router
      })
    </script>
  </body>
</html>

如果使用$route.params.id来获取路径传参的数据不够灵活。可以通过props来接收参数

在这里插入图片描述

函数类型的props: route => ({ uname: ‘zs’, age: 20, id: route.params.id })既可以配到路径的id也可以配到数据
