vue3+vite注册动态路由的实践

目的是先将从后端拿到返回的路由列表的component与本地的路径进行比对，然后将匹配的数据拿到后再渲染，注意，使用动态路由注册后的路由需要走一次replace,否则将无法渲染

// route/index.js

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'
//  const comp = () => import ('../views/AboutView.vue' )
// console.log('comp :>> ', await comp()?.default)
 const baseRoute = [
   {
     path: '/',
     name: 'home',
     component: HomeView
   },
   {
     path: '/about',
     name: 'about',
     component: () => import('../views/AboutView.vue')
   }
 ]
 console.log('baseRoute :>> ', baseRoute );
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: baseRoute 
})
const page = import.meta.glob('../views/**/*.vue', { eager: true })
const cru = Object.entries(page)
// 递归添加路由
const loadRoute = (list) => {
  list.forEach((item) => {
    const path = item.site // size：后端配置好的路由地址
    console.log('path :>> ', path);
    cru.forEach( async cruItem => {
      // cruItem是一个二维数组
      if (cruItem[0] === path) {
        // 注意：异步渲染，需要走await才能返回读取后的组件数据
        item.component = await cruItem[1]?.default
        console.log('cruItem[1] :>> ', cruItem[1]);
        console.log('11111 :>> ', 11111);
        console.log('path :>> ', path);
        console.log('11111 :>> ', 11111)
      }
    })
    router.addRoute(item)
    if (item.children) {
      loadRoute(item.children)
    }
  })
}
console.log('page :>> ', page);
const asyncRoute = [
  {
    path: '/layout',
    name: 'layout',
    site: '../views/Layout.vue',
    redirect: '/demo1',
    component: () => import('../views/Layout.vue'),
    children: [
      {
        path: '/demo1',
        name: 'demo1',
        site: '../views/Demo1.vue',
        component: () => import('../views/Demo2.vue')
      },
      {
        path: '/test1',
        name: 'test1',
        site: '../views/test/test1.vue',
        component: () => import('../views/text/test1.vue')
      },
      {
        path: '/test2',
        name: 'test2',
        site: '../views/test/test2.vue',
        component: () => import('../views/test/test2.vue')
      }
    ]
  }
] 
 
  
router.beforeEach((to, from, next) => {
  if (!router.hasRoute('layout')) { 
    loadRoute(asyncRoute)
    // console.log('asyncRoute :>> ', asyncRoute);
    router.replace({...to,replace:true})
  }
  console.log('router.getRoutes() :>> ', router.getRoutes())
  next()
})
 
export default router
