import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
//引入创建的两个组件
import Cart from './Cart.vue'
import Me from './Me.vue'
//使用路由实例插件
Vue.use(VueRouter)
const router = new VueRouter({
 mode:'history',
 base: '__dirname',
 routes:[
 //将页面组件与path指令的路由关联
 {path:'/cart',component:Cart},
 {path:'/me',component:Me}
 ]
})
new Vue({
 el: '#app',
 //将路由实例添加到Vue实例中去
 router,
 render: h => h(App)
})
