路由重定向
重定向到路由地址
通过属性 redirect 指定重定向的路由地址：
const router = new VueRouter({
routes: [
{ path: '/a', redirect: '/b' }
]
})

template: '<div>Hello，欢迎使用慕课网学习 Vue 教程！</div>',
})
const Article = Vue.component('myArticle', {
template: `<ul><li>1. Vue 计算属性的学习</li><li>2. React 基础学习</li></ul>`,
})
const routes = [
{ path: '/', redirect: '/index' },
{ path: '/index', component: Index },
{ path: '/article', component: Article }
]
const router = new VueRouter({
routes: routes
})
var vm = new Vue({
el: '#app',
router: router,
data() {
return {}
}
})
</script>

重定向到具名路由
通过属性 redirect 重定向到具名路由：
const router = new VueRouter({
routes: [
{ path: '/a', redirect: {name: 'name'} }
]
})

})
const Article = Vue.component('myArticle', {
template: `<ul><li>1. Vue 计算属性的学习</li><li>2. React 基础学习</li></ul>`,
})
const routes = [
{ path: '/', redirect: {name: 'index'} },
{ path: '/index', name: 'index', component: Index },
{ path: '/article', name: 'article', component: Article }
]
const router = new VueRouter({
routes: routes
})
var vm = new Vue({
el: '#app',
router: router,
data() {
return {}
}
})
</script>
</html>
动态返回重定向目标
属性 redirect 可以接收一个方法，动态返回重定向目标：
const router = new VueRouter({
routes: [
{ path: '/a', redirect: to => {
// 方法接收 目标路由 作为参数
// return 重定向的 字符串路径/路径对象
}}
]
})

if(Math.random() > 0.5) {
return '/index'
}else {
return {
name: 'article'
}
}
}},
{ path: '/index', name: 'index', component: Index },
{ path: '/article', name: 'article', component: Article }

const router = new VueRouter({
routes: routes
})

路由别名
“重定向”的意思是，当用户访问 /a 时，URL 将会被替换成 /b，然后匹配路由为 /b，那么“别名”又是什么呢？
/a 的别名是 /b，意味着，当用户访问 /b 时，URL 会保持为 /b，但是路由匹配则为 /a，就像用户访问 /a 一样。
const router = new VueRouter({
routes: [
{ path: '/a', component: A, alias: '/b' }
]
})
