路由：

一个路由就是一组映射关系（key - value）

router/index.js

//该文件用于创建整个应用的路由器

import VueRouter from "vue-router";
import Home from '../pages/Home';
import About from '../pages/About';
//创建路由器
const router = new VueRouter({
    routes: [
        {
            path: '/about',
            component: About
        },
        {
            path: '/home',
            component: Home
        }
    ]
})

export default router
