Vue history模式和hash模式

路由器默认工作模式为hash模式

//引入文件，该文件专门用于创建整个应用的路由器
import VueRouter from 'vue-router'
//引入组件
import About from '../components/Home'
import Home from '../components/About'
import Message from '../components/Message'
import Detail from '../components/Detail'
//创建并暴露一个路由器
export default new VueRouter({
	mode:'hash',           //也可以切换为history模式
    routes: [{
            name:'about',
            path: '/about',
            component: About
        },
        {
            name:'home',
            path: '/home',
            component: Home,
            children: [{
            	name:'message/:id/:title', //占位符
                path: "message",
                component: Message
            }]
        }
    ]
})
