vue权限管理——菜单权限设置

news 2025/7/10 22:59:14

1.前提：后端提供菜单对应数据

此处用mockjs模拟

const menuList = [{'id': 1, path:'/uploadSpec','authName': "上传spec", icon: 'User', children:[], rights:['view','add','edit','delete']},{'id': 2, path:'/showSpec', 'authName': "Spec预览", icon: 'DataAnalysis',children:[], rights:['view','add','edit','delete']},{'id': 3, path:'/generateTxt', 'authName': "生成测试数据", icon: 'DataAnalysis',children:[], rights:['view','add','edit','delete']},{'id': 4, path:'/generateCronjob', 'authName': "生成转码程序", icon: 'Promotion',children:[], rights:['view','add','edit','delete']},{'id': 5, path:'/pdfCompare', 'authName': "PDF文档对比", icon: 'DocumentCopy',children:[], rights:['view','add','edit','delete']},{'id': 6, path:'/resourceUpdate', 'authName': "资源更新管理", icon: 'Management',children:[], rights:['view','add','edit','delete']},{'id': 7, path:'/generateTestCase', 'authName': "自动生成ST/SIT案例", icon: 'Files',children:[], rights:['view','add','edit','delete']},{'id': 8, path:'/userManagement', 'authName': "用户管理", icon: 'User', rights:['view']},{'id': 9, path:'/roleManagement', 'authName': "角色管理", icon: 'Stamp', rights:['view']},
]

2.登录后将获取的菜单信息同时设置到vuex和sessionStorage中

import * as api from '@/api/api'
import { ElMessage } from 'element-plus'const state = () => {return {user:JSON.parse(sessionStorage.getItem("user") || '{}'),menuList: JSON.parse(sessionStorage.getItem("menuList") || '[]'),}
}const getters = () => {}const actions = {// 注意async位置和箭头函数写法login: async({ commit }, user) => {// 调用登录接口try {let result = await api.login(user);if (result.data.code === 200) {sessionStorage.setItem("token", result.data.data.token);// 调用获取user信息接口let loginUser = await api.getLoginUser();// 调用mutations的login方法if (loginUser.data.code === 200) {commit('login', loginUser.data.data);} else {ElMessage.error("登录失败：用户信息获取失败");}} else {ElMessage.error("登录失败：" + result.data.errorMsg);}} catch (error) {throw error;}},register: async({ commit, state }, user) => {// 调用注册接口，注册不需要更新vuex，所以不需要调用mutationstry {let registerUser = await api.register(user);if (registerUser) return registerUser;} catch (error) {throw error;}},
}const mutations = {initUser: (state) => {// 从localStorage中获取数据设置进user中，否则通过刷新页面时，获取不到state中的user信息state.user = JSON.parse(sessionStorage.getItem("loginUser"));},login: (state, user) => {// 登录成功后将user信息存到state中，且缓存到localStorage中        state.user = user;state.menuList = user.menuList;sessionStorage.setItem("loginUser", JSON.stringify(user));sessionStorage.setItem("menuList", JSON.stringify(user.menuList));},
}export default {namespaced: true,state,getters,actions,mutations
}

3. TAside.vue侧边栏中引入vuex的菜单信息

        <el-menu:default-active="$route.path"routeractive-text-color="#ffd04b"background-color="#545c64"text-color="#fff"><template #title><el-icon><i-ep-message /></el-icon>导航菜单</template><!-- 根据后端返回rights数据渲染菜单 --><el-menu-item :index="menu.path" v-for="menu in menuList" :key="menu.id">{{menu.authName}}</el-menu-item></el-menu>
...
import { computed } from "vue";
import { useStore } from "vuex";const store = useStore();
const menuList = computed(() => store.state.user.menuList);
...
