路由重定向

重定向到路由地址

通過屬性 redirect 指定重定向的路由地址：

const router = new VueRouter({
  routes: [
    { path: '/a', redirect: '/b' }
  ]
})

示例

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>Document</title>
</head>
<body>
  <div id="app">
    <div>
      <router-link to="/index">首頁</router-link>
      <router-link to="/article">文章</router-link>
    </div>
    <router-view></router-view>
  </div>
</body>

<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<script type="text/javascript">

const Index = Vue.component('index', {
  template: '<div>Hello，歡迎使用慕課網學習 Vue 教程！</div>',
})

const Article = Vue.component('myArticle', {
  template: `<ul><li>1. Vue 計算屬性的學習</li><li>2. React 基礎學習</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>
</html>

重定向到具名路由

通過屬性 redirect 重定向到具名路由：

const router = new VueRouter({
  routes: [
    { path: '/a', redirect: {name: 'name'} }
  ]
})

示例

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>Document</title>
</head>
<body>
  <div id="app">
    <div>
      <router-link to="/index">首頁</router-link>
      <router-link to="/article">文章</router-link>
    </div>
    <router-view></router-view>
  </div>
</body>

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<script type="text/javascript">

const Index = Vue.component('index', {
  template: '<div>Hello，歡迎使用慕課網學習 Vue 教程！</div>',
})

const Article = Vue.component('myArticle', {
  template: `<ul><li>1. Vue 計算屬性的學習</li><li>2. React 基礎學習</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>

動態返回重定向目標

屬性 redirect 可以接收一個方法，動態返回重定向目標：

const router = new VueRouter({
  routes: [
    { path: '/a', redirect: to => {
      // 方法接收 目標路由 作為引數
      // return 重定向的 字串路徑/路徑物件
    }}
  ]
})

})

const routes = [
{ path: '/', redirect: to => {
  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
})

var vm = new Vue({
  el: '#app',
  router: router,
  data() {
    return {}
  }
})
</script>
</html>

路由別名

“重定向”的意思是，當用戶訪問 /a 時，URL 將會被替換成 /b，然後匹配路由為 /b，那麼“別名”又是什麼呢？
/a 的別名是 /b，意味著，當用戶訪問 /b 時，URL 會保持為 /b，但是路由匹配則為 /a，就像使用者訪問 /a 一樣。

const router = new VueRouter({
  routes: [
    { path: '/a', component: A, alias: '/b' }
  ]
})
