Vue3动态导入后端路由

1. 动态获取文件

// modules就是一个map，文件路径作为key，文件对象作为value
const modules=import.meta.glob('../views/**/*.vue')

获取到的modules对象如下：

2. 添加动态路由

import {createRouter, createWebHashHistory} from 'vue-router'

const modules = import.meta.glob('../views/**/*.vue')

const constantRoutes = [
    {
        path: '/login',
        name: 'login',
        meta: {
            title: '登录',
            hidden: true
        },
        component: () => import('../views/login/index.vue')
    },
]

const router = createRouter({
    history: createWebHashHistory(),
    routes:[…constantRoutes]
})

// 从后端动态获取的路由列表,[hidden:是否在侧边栏显示]
let dynamicRoutes = [
    {
        path: '/',
        name: 'Layout',
        redirect: '/home',
        component: '/views/layout/index',
        meta: {
            title: 'Layout',
            icon: 'HomeFilled',
            hidden: false
        },
        children: [
            {
                path: '/home',
                name: 'Home',
                component: '/views/home/index',
                meta: {
                    title: '首页',
                    icon: 'HomeFilled',
                    hidden: false
                }
            },
        ]
    },
    {
        path: '/sys',
        name: 'Sys',
        component: '/views/layout/index',
        meta: {
            title: '系统管理',
            icon: 'document',
            hidden: false
        },
        children: [
            {
                path: '/sys/user',
                name: 'User',
                component: '/views/sys/user/index',
                meta: {
                    title: '用户管理',
                    icon: 'document',
                    hidden: false
                }
            },
            {
                path: '/sys/role',
                name: 'Role',
                component: '/views/sys/role/index',
                meta: {
                    title: '角色管理',
                    icon: 'document',
                    hidden: false
                }
            },
        ]
    }
]

convertPathToComponent(dynamicRoutes)
addDynamicRoutes(dynamicRoutes)

// 添加动态路由
function addDynamicRoutes(dynamicRoutes) {
    dynamicRoutes.forEach(item => {
        router.addRoute(item)
    })
}

// 使用递归将routeList中每个对象及其子对象中的component路径转换为组件（在component不为空的情况下）
function convertPathToComponent(dynamicRoutes) {
    dynamicRoutes.forEach(item => {
        if (item.component) {
            item.component = modules['..' + item.component + '.vue'] || modules['../views/404/index.vue']
        }
        if (item.children) {
            convertPathToComponent(item.children)
        }
    })
}

export default router
