import About from '../pages/About'
import Home from '../pages/Home'
import News from '../pages/News'
import Message from '../pages/Message'
import Detail from '../pages/Detail'

//创建并暴露一个路由器
export default new VueRouter({
    routes:[
        {
            name:'guanyu',
            path:'/about',
            component:About
