wordpress建立移动m站上海公共场所

在 Vue 3、TypeScript 和 Vite 项目中，设置动态目录以及目录权限，通常涉及到路径别名的配置、动态路由的实现以及权限控制的逻辑。以下是具体的实现步骤：

1. 动态路由的实现

定义静态路由

在 router/index.ts 中定义静态路由，例如登录页、首页等。

import { createRouter, createWebHistory } from 'vue-router';
import Layout from '@/layout/index.vue';export const constantRoutes = [{path: '/',redirect: '/dashboard',hidden: true,},{path: '/dashboard',name: 'Dashboard',meta: {title: '首页',icon: 'House',},component: Layout,},{path: '/login',name: 'Login',meta: {title: '登录',},component: () => import('@/views/user/login/index.vue'),hidden: true,},{path: '/:pathMatch(.*)*',component: () => import('@/views/error/404.vue'),hidden: true,},
];const router = createRouter({history: createWebHistory(),routes: constantRoutes,
});export default router;

动态加载路由

创建一个函数来动态加载路由，通常在权限相关的 store 中实现。

import { ref } from 'vue';
import router from '@/router';
import type { RouteRecordRaw } from 'vue-router';const asyncRoutes = ref<RouteRecordRaw[]>([]);export const useRouterConfig = () => {const modules = import.meta.glob('@/views/**');const addRoutes = (menus: RouteRecordRaw[]) => {asyncRoutes.value = menus;filterAsyncRouter();router.addRoute({path: '/',redirect: asyncRoutes.value[0].path,});};const filterAsyncRouter = () => {const routerLoop = (routes: RouteRecordRaw[], 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,};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) => {const 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 };
};

2. 权限控制

在导航守卫中进行权限控制，确保用户只能访问其有权限的路由。

import router from './index';
import { useUserStore } from '@/store/user';const whiteList = ['/login', '/404'];router.beforeEach(async (to) => {const token = localStorage.getItem('token');if (whiteList.includes(to.path) && !token) {return true;} else {const { menuList, getMenuList } = useUserStore();if (!menuList.length) {await getMenuList();return { path: to.fullPath };}}
});

3. 获取后端路由数据

在 store/user.ts 中定义获取用户菜单列表的逻辑。

import { defineStore } from 'pinia';
import { ref } from 'vue';export const useUserStore = defineStore('user', () => {const menuList = ref([]);const getMenuList = async () => {// 这里是获取后端路由数据的 API 调用// 模拟获取数据menuList.value = [{path: '/dashboard',name: 'Dashboard',meta: { title: '首页', icon: 'House' },component: 'Layout',},{path: '/user',name: 'User',meta: { title: '用户管理', icon: 'User' },component: 'Layout',children: [{path: '/user/list',name: 'UserList',meta: { title: '用户列表' },component: () => import('@/views/user/list.vue'),},],},];};return { menuList, getMenuList };
});

4. 动态路由的初始化

在 main.ts 中初始化动态路由。

import { createApp } from 'vue';
import App from './App.vue';
import router from './router';
import { useRouterConfig } from './router/config';
import { useUserStore } from './store/user';const app = createApp(App);
app.use(router);// 初始化动态路由
const { addRoutes } = useRouterConfig();
const userStore = useUserStore();
addRoutes(userStore.menuList);app.mount('#app');

通过以上步骤可以实现 Vue 3、TypeScript 和 Vite 项目中的动态目录设置和目录权限控制。这包括了路径别名的配置、动态路由的实现以及权限控制的逻辑。
