一、菜单权限

1.1 路由拆分 

 将项目路由拆分为：

• 静态路由：login、404、home、screen
• 异步路由：权限管理（包含三个子路由）、商品管理（包含四个子路由）
• 任意路由：任意路由

 src/router/routes.ts

// 对外暴露配置路由（常量路由）：全部用户都可以访问到的路由
export const constantRoute = [{// 登录path: '/login',component: () => import('@/views/login/index.vue'),name: 'login',meta: {title: '登录', // 菜单标题hidden: true, // 代表路由标题在菜单中是否隐藏  true:隐藏  false:显示icon: 'Promotion', // 菜单文字左侧的图标,支持element-plus全部图标},},{// 登录成功以后展示数据的路由path: '/',component: () => import('@/layout/index.vue'),name: 'layout',meta: {title: '',hidden: true,icon: '',},redirect: '/home',children: [{path: '/home',component: () => import('@/views/home/index.vue'),name: 'home',meta: {title: '首页',hidden: false,icon: 'HomeFilled',},},],},{// 404path: '/404',component: () => import('@/views/404/index.vue'),name: '404',meta: {title: '404',hidden: true,icon: 'BrushFilled',},},{path: '/screen',component: () => import('@/views/screen/index.vue'),name: 'Screen',meta: {title: '数据大屏',hidden: false,icon: 'Platform',},}
]//异步路由
export const asnycRoute = [{path: '/acl',component: () => import('@/layout/index.vue'),name: 'Acl',meta: {title: '权限管理',icon: 'Lock',},redirect: '/acl/user',children: [{path: '/acl/user',component: () => import('@/views/acl/user/index.vue'),name: 'User',meta: {title: '用户管理',icon: 'User',},},{path: '/acl/role',component: () => import('@/views/acl/role/index.vue'),name: 'Role',meta: {title: '角色管理',icon: 'UserFilled',},},{path: '/acl/permission',component: () => import('@/views/acl/permission/index.vue'),name: 'Permission',meta: {title: '菜单管理',icon: 'Monitor',},},],},{path: '/product',component: () => import('@/layout/index.vue'),name: 'Product',meta: {title: '商品管理',icon: 'Goods',},redirect: '/product/trademark',children: [{path: '/product/trademark',component: () => import('@/views/product/trademark/index.vue'),name: 'Trademark',meta: {title: '品牌管理',icon: 'ShoppingCartFull',},},{path: '/product/attr',component: () => import('@/views/product/attr/index.vue'),name: 'Attr',meta: {title: '属性管理',icon: 'ChromeFilled',},},{path: '/product/spu',component: () => import('@/views/product/spu/index.vue'),name: 'Spu',meta: {title: 'SPU管理',icon: 'Calendar',},},{path: '/product/sku',component: () => import('@/views/product/sku/index.vue'),name: 'Sku',meta: {title: 'SKU管理',icon: 'Orange',},},],},
]//任意路由
export const anyRoute = {// 任意路由path: '/:pathMatch(.*)*',redirect: '/404',name: 'Any',meta: {title: '任意路由',hidden: true,icon: 'Wallet',},
}

1.2  菜单权限业务实现 

 PS：退出登录记得删除添加的路由，防止切换角色后还能访问另一个角色的权限

src/store/modules/user.ts

......
// 引入路由(常量路由)
import { constantRoute, asnycRoute, anyRoute } from '@/router/routes'// 引入深拷贝方法
//@ts-expect-error
import cloneDeep from 'lodash/cloneDeep'
import router from '@/router'
// 用于过滤当前用户需要展示的异步路由
function filterAsyncRoute(asnycRoute: any, routes: any) {return asnycRoute.filter((item: any) => {if (routes.includes(item.name)) {if (item.children && item.children.length > 0) {item.children = filterAsyncRoute(item.children, routes)}return true}})
}
......const useUserStore = defineStore('User', {// 小仓库存储数据的地方state: (): UserState => {return {......menuRoutes: constantRoute, // 仓库存储生成菜单需要数组（路由）   removeRouteCallbackList: []}},// 异步|逻辑的地方actions: {......// 获取用户信息async userInfo() {// 获取用户信息进行存储仓库当中（用户头像、名字）let result: userInfoResponeData = await reqUserInfo()// 如果获取信息成功，存储下用户信息if (result.code === 200) {this.username = result.data.namethis.avatar = result.data.avatar// 计算当前用户需要展示的异步路由const userAsyncRoute = filterAsyncRoute(cloneDeep(asnycRoute),result.data.routes)// 菜单需要的数据整理完毕this.menuRoutes = [...constantRoute, ...userAsyncRoute, anyRoute]// 目前路由器管理的只有常量路由:用户计算完毕异步路由、任意路由动态追加;[...userAsyncRoute, anyRoute].forEach((route: any) => {let removeRoute = router.addRoute(route)this.removeRouteCallbackList.push(removeRoute)})return 'ok'} else {return Promise.reject(new Error(result.message))}},// 退出登录async userLogout() {let result: any = await reqLogout()if (result.code === 200) {// 目前没有mock接口：退出登录接口（通知服务器本地用户唯一标识失败）this.token = ''this.username = ''this.avatar = ''REMOVE_TOKEN()// 退出登录时删除登录添加的路由this.removeRouteCallbackList.forEach((removeRouteCallback: any) => {removeRouteCallback()})return 'ok'} else {return Promise.reject(new Error(result.message))}},},getters: {},
})

刷新的时候是异步路由，有可能获取到用户信息，异步路由还没有加载完毕，出现空白的效果！！

解决方法：在全局前置守卫中，获取用户信息后改成next({...to})

• next() ：直接放行（这种写法会导致刷新产生空白的效果）
• next({...to})：等待路由加载完毕再放行

src/permission.ts

......try {// 获取用户信息await useStore.userInfo()// 放行//等待路由加载完毕再放行next({ ...to})} catch (error) {}.......

 二、按钮权限

1.1 按钮权限业务实现 

1.1.1 用户按钮权限信息存储

src/store/modules/user.ts 

......
state: (): UserState => {return {......//存储当前用户是否包含某一个按钮buttons: [],}
......
async userInfo() {......// 如果获取信息成功，存储下用户信息if (result.code === 200) {......this.buttons = result.data.buttons......}

 1.1.2 定义全局自定义指令

src/directive/has.ts 

import pinia from "@/store"
import useUserStore from "@/store/modules/user"
const userStore = useUserStore(pinia)
export const isHasButton = (app: any) => {// 获取对应的用户仓库// 全局自定义指令：实现按钮的权限app.directive('has', {// 代表使用这个全局指令的DOM|组件挂载完毕的时候会执行一次mounted(el: any, options: any) {// 自定义指令右侧的数值：如果在用户信息buttons数组中没有// 从DOM树上干掉if (!userStore.buttons.includes(options.value)) {el.parentNode.removeChild(el)}},})
}

 在main.ts文件中引入自定义指令文件

// 引入自定义指令文件
import { isHasButton } from '@/directive/has'
isHasButton(app)

 1.1.3 使用自定义指令配置按钮权限

PS:此处以其中一个按钮作为例子，项目中其他按钮的权限都需要配置

<el-button type="primary" size="default" icon="Plus" @click="addTrademark" v-has="'btn.Trademark.add'">
