要想实现vite+vue-router实现动态路由我们需要用到

1. addRoute()

官方文档中addRoute的使用

当我们添加一个主路由的时候

router.addRoute({ path: '/permission', name: 'permission', component: () => import('xxxxx')})

添加子路由也就是嵌套路由

router.addRoute('主路由的name', { path: 'settings', component: AdminSettings })

2. 导航守卫使用时的注意事项，否则会出现刷新白屏，或者路由访问死循环等

之前我们使用导航守卫的时候需要一个参数next()去控制是否放行以及去哪个页面，但是在新版本的vue-router里面可以不是用next()

我们可以新建一个permission.ts文件

import router from "./index";
import { useSessionStorage } from "@vueuse/core";
import { StorageEnum } from "@/enum";
import { useUserStore } from "@/store";const whiteList = ["/login", "/404"];router.beforeEach(async (to) => {const token = useSessionStorage(StorageEnum.TOKEN, "").value;// 如果在白名单里面 并且 token 不存在if (whiteList.includes(to.path) && !token) {return true;} else {const { menuList, getMenuList } = useUserStore();// 如果为空数组，name就请求接口重新获取后端维护的路由数据if (!menuList.length) {await getMenuList();console.log("获取全部路由 =>", router.getRoutes());// 触发重定向 不这样写会导致刷新找不到路由 两种写法都行// return { path: to.fullPath };return to.fullPath;}}
});

出现404的话比如说你在路由表中维护了下面路由映射

{path: "/:pathMatch(.*)",name: "page404",component: () => import("@/views/system/404.vue"),
}

3. 获取后端tree数据，递归循环，可能业务会有type类型，比如分为模块，菜单，页面，按钮等，到时候结合业务去实现逻辑

4.import.meta.glob()

import.meta.glob动态的去拼接获取文件,把后台返回内容转换成() => import('xxxx')格式

以下代码仅供参考，有很多需要完善的地方

import type { RouterType } from "@/router/type";
import router from "@/router";
import type { RouteRecordRaw } from "vue-router";export const useRouterConfig = () => {// 获取views目录下的所有的文件 不要使用@别名 const modules = import.meta.glob("../views/**");const asyncRoutes = ref<RouterType[]>([]);const addRoutes = (menus: RouterType[]) => {asyncRoutes.value = menus;filterAsyncRouter();// 动态添加 / 路由router.addRoute({path: "/",redirect: asyncRoutes.value[0].path,});};const filterAsyncRouter = () => {const routerLoop = (routes: RouterType[], ParentName?: string) => {routes.forEach((item) => {if (item.component === "Layout") {item.component = () => import("@/layout/index.vue");} else {item.component = resolveComponent(item.component);}const { title, show, icon, name, path, component, children } = item;const route: RouteRecordRaw = {component,path,name,meta: {title,show,icon,},children: children as any,};// 动态添加路由if (ParentName) {router.addRoute(ParentName, route);} else {router.addRoute(route);}if (item.children && item.children.length > 0) {routerLoop(item.children, item.name);}});};routerLoop(asyncRoutes.value);};const resolveComponent = (path: string) => {console.log(modules);// 拿到views下面的所有文件之后，动态拼接`key`去获取valueconst importPage = modules[`../views${path}`];if (!importPage) {throw new Error(`Unknown page ${path}. Is it located under Pages with a .vue extension?`);}return importPage;};return { addRoutes };
};
