全动态vue-router [英] Fully dynamic vue-router

问题描述

我们正在构建一个基于 Vue 和 Nuxt 的庞大网站，其中包含超过 25 种不同的页面类型，这些页面类型无法与 Vue Router 开箱即用的标准/:id 或/overview/:slug 逻辑匹配.

由于 slug-matching 不是一种选择，我们正在考虑以下解决方案:

1. 用户访问页面/this-is-a-topic-page"
2. 服务器调用返回 pageType 的 API topicPage
3. topicPage 与 nuxt 页面相关 WpTopicPage
4. 我们在 Vue Router 的通配符实例中将 WpTopicPage 设置为我们的组件

代码如下:

导出函数 createRouter() {返回新路由器({模式:'历史'，路线:[//1. 用户访问页面/this-is-a-topic-page"{name: '通配符',小路: '*'，组件: *,//这应该是动态的beforeEnter: (to, from, next) =>{//2. 服务器调用返回pageType`topicPage`的APIthis.$axios.get(`/call-to-the-api?slug=${to.params.slug}`).then((res) => {//3.`topicPage`与nuxt页面`WpTopicPage`相关if(res.data.pageType === 'topicPage') {//4. 设置 `WpTopicPage` 作为我们的页面组件返回 WpTopicPage；}})},},],});}

以上显然行不通.有没有办法在 beforeEnter 函数中动态设置路由内的 component ?

解决方案

这是可能的.我创建了一个

正如您在控制台日志中看到的那样 - 每次发生变化时，我们都会加载和安装随机组件.

We are building an enormous website based on Vue and Nuxt with over 25 different page types that cannot be matched with standard /:id or /overview/:slug logic that comes out of the box with Vue Router.

As slug-matching isn't an option, we are thinking about the following solution:

1. User visits page "/this-is-a-topic-page"
2. Server calls API that returns the pageType topicPage
3. topicPage relates to the nuxt page WpTopicPage
4. We set WpTopicPage as our component within our wildcard instance of Vue Router

This looks like the following in code:

export function createRouter() {
  return new Router({
    mode: 'history',
    routes: [
      // 1. User visits page "/this-is-a-topic-page"
      {
        name: 'wildcard',
        path: '*',
        component: *, // this should be dynamic
        beforeEnter: (to, from, next) => {
          // 2. Server calls API that returns the pageType `topicPage`
          this.$axios.get(`/call-to-the-api?slug=${to.params.slug}`)
            .then((res) => {
              // 3. `topicPage` relates to the nuxt page `WpTopicPage`
              if(res.data.pageType === 'topicPage') {
                // 4. Set `WpTopicPage` as our Page component
                return WpTopicPage;
              }
            })
        },
      },
    ],
  });
}

The above obviously doesn't work. Is there a way to set the component within a route dynamically in the beforeEnter function?

解决方案

It's possible to do. I have created a codepen for you to test:

Here it is:

Vue.use(VueRouter);

let A = {
  mounted() {
    console.log('Mouted component A');
  },
};
let B = {
  mounted() {
    console.log('Mouted component B');
  },
};
let C = {
  mounted() {
    console.log('Mouted component C');
  },
};

const router = new VueRouter({
  mode: "hash",
  routes: [
    {
      path: '*',
      beforeEnter(to, from, next) {
        let components = {
          default: [A, B, C][Math.floor(Math.random() * 100) % 3],
        };
        to.matched[0].components = components;
        
        next();
      }
    },
  ]
});

app = new Vue({
  router,
  el: '#app',
  components: { A, B, C }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue-router/3.0.2/vue-router.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <router-link :to="'/' + Math.random()">anything</router-link>
  <router-view></router-view>
</div>

This is the output:

As you can see in the console logs - each time something changes we get random component loaded and mounted.
