vue的重定向和404

　　

//創建路由對象並配置路由規則
let router = new VueRouter({ routes:[ {path:'/',redirect:{name:"home"}},  // 重定向到主頁
       {name:'home',path:'/home',component:Home}, {path:'/music',component:Music}, {path:'/movie',component:Movie}, {name:'img',path:'/picture22',component:Picture}, {name:'musicDetail',path:'/musicDetail/:id/:name',component:MusicDetail}, {path:'*',component:NotFound},//全不匹配的情況下，返回404，路由按順序從上到下，依次匹配。最后一個*能匹配全部，
 ] });
