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> //子组件 <template v-for="item in props.apidto" key="item"> <el-sub-menu v-if="item.children && item.children.length > 0" :index="item.mName" :key="item"> <template #title> <el-icon> <component :is="item.mIcol" /> </el-icon> <span>{{ item.mName }}</span> </template> <RecursiveMenuItem :apidto="item.children" /> <!-- 递归调用自身 --> </el-sub-menu> <el-menu-item v-else :index="item.roUrl"> <el-icon> <component :is="item.mIcol" /> </el-icon> <span>{{ item.mName }}</span> </el-menu-item> </template>
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);
