动态路由
动态菜单
//通过循环组件完成动态菜单<el-menu active-text-color="#ffd04b" background-color="#545c64" class="el-menu-vertical-demo" text-color="#fff":collapse="isCollapse" router default-active style="width: auto;"><el-menu-item index="99"><img src="@/assets/logo.svg" width="18" /><span style="font-weight: bold;">TMS用户管理系统</span></el-menu-item><el-menu-item index="/Main"><el-icon><HomeFilled /></el-icon><span>首页</span></el-menu-item><RecursiveMenuItem :apidto="apidto" /><el-menu-item@click="isCollapse = !isCollapse; isCollapse == true ? iconSwitch = 'Expand' : iconSwitch = 'Fold'"><el-icon style="font-size: 20px;"><component :is="iconSwitch"></component></el-icon><span>展开</span></el-menu-item></el-menu>

动态路由
import router from '@/router/index'
const modules = import.meta.glob('../views/**/*.vue')
//导航守卫+动态路由
//to是要跳转到的页面
//form是跳转前的页面
//next是不做任何阻拦允许跳转
router.beforeEach((to, from, next) => {//pinia中获取用户登录状态const CounterStore = useCounterStore();//是否为登录状态,并且令牌不为空if (CounterStore.isLogin && localStorage.getItem('token')) {//如果路由是登录页面则跳转到主页if (to.path === '/') {next({path: '/Main'})}//不为登录页面else {//如果路由不存在则添加路由if (to.name === undefined) {const routes = JSON.parse(localStorage.getItem('apidto') as string);addRoutesRecursively(routes);next({ ...to, replace: true })}next();}}//如果没有登录else {if (to.path === '/') {next()}else {next({path: '/'})}}
})
//递归获取用户
function addRoutesRecursively(routes: any[]) {routes.forEach((route) => {// 假设 route 可能包含 children 属性 if (route.children) {// 递归调用自身来处理 children addRoutesRecursively(route.children);}// 添加当前路由else {router.addRoute('Main', {path: route.roUrl,name: route.roName,component: modules['../views' + route.moUrl] // 注意这里可能需要根据实际情况调整路径拼接方式 });}});
}
动态按钮
//pinia状态管理
import { useUserStore } from '../stores/User'
import type { Directive, DirectiveBinding } from "vue";//权限按钮自定义事件export const hasPerm: Directive = {mounted(el: HTMLElement, binding: DirectiveBinding) {// DOM绑定需要的按钮权限标识const { value: requiredPerms } = binding;if (requiredPerms) {if (!hasAuth(requiredPerms)) {el.parentNode && el.parentNode.removeChild(el);}} else {throw new Error("你没有权限");}},
};// 是否有权限
function hasAuth(value: string | string[],type: "button" | "role" = "button"//约束type只能为button或role,同时赋值默认值button
) {//获取账号下的角色和权限const userStore = useUserStore();const { roles, perms } = userStore.users;//「终极管理员」拥有所有的按钮权限if (type === "button" && roles.includes("终极管理员")) {return true;}//判断是否获取的是按钮权限，否则获取角色权限const auths = type === "button" ? perms : roles;//判断用户value是一堆角色还是单个角色return typeof value === "string"? auths.includes(value)//判断用户是否有这个权限: auths.some((perm) => {return value.includes(perm);//查询需要的权限是否拥有，可能是一个按钮可以有好几个角色访问});
}//Main中注册
//注册全局自定义指令
app.directive("hasPerm", hasPerm);
