1 第一个bug
分配菜单时未加入父id，导致分配菜单失效
<!-- :check-strictly="true" 默认是false，父子关联;true 是不关联需手动勾选父选择框
-->
<el-tree:props="props":data="menuData"show-checkboxnode-key="id"ref="tree":check-strictly="true":default-expanded-keys="expends":default-checked-keys="checks"><span class="custom-tree-node" slot-scope="{ node, data }"><span><i :class="data.icon"></i> {{ data.name }}</span></span></el-tree>

2 第二个bug
启动成功前端访问地址，弹出的是404页面不是登录页面
2.1 修改路由router下面的index.js
修改的地方
// 第一处
{path: '/404',name: '404',component: () => import('../views/404.vue')}// 第二处
// 路由守卫
router.beforeEach((to, from, next) => {// localStorage.setItem('currentPathName',to.name); // 设置当前的路由名称，为了在Header组件中去使用// store.commit('setPath') // 触发store的数据更新// 未找到路由情况if(!to.matched.length){const storeMenus = localStorage.getItem("menus");if(storeMenus){ // 有菜单没有找到路由，跳转至 404页面next("/404")}else { // // 没有菜单，直接跳转至登录页next("/login")}}next() // 放行路由
})完整的代码
import Vue from 'vue'
import VueRouter from 'vue-router'
import Manage from '../views/Manage.vue'
import store from "@/store";Vue.use(VueRouter)
//定义一个路由对象数组
const routes = [{path: '/login',name: '登录',component: () => import('../views/Login.vue')},{path: '/register',name: '注册',component: () => import('../views/Register.vue')},{path: '/404',name: '404',component: () => import('../views/404.vue')}]//使用路由对象数组创建路由实例，供main.js引用
const router = new VueRouter({mode: 'history',base: process.env.BASE_URL,routes
})// 注意：刷新页面会导致页面路由重置
export const setRoutes = () => {const storeMenus = localStorage.getItem("menus");if (storeMenus) {// 获取当前的路由对象名称数组const currentRouteNames = router.getRoutes().map(v => v.name)if (!currentRouteNames.includes('Manage')) {// 拼装动态路由const manageRoute = { path: '/', name: 'Manage', component: () => import('../views/Manage.vue'), redirect: "/home", children: [{ path: 'person', name: '个人信息', component: () => import('../views/Person.vue')},// { path: 'password', name: '修改密码', component: () => import('../views/Password.vue')}] }const menus = JSON.parse(storeMenus)menus.forEach(item => {if (item.path) { // 当且仅当path不为空的时候才去设置路由let itemMenu = { path: item.path.replace("/", ""), name: item.name, component: () => import('../views/' + item.pagePath + '.vue'),meta: { title: item.name }}manageRoute.children.push(itemMenu)} else if(item.children.length) {item.children.forEach(item => {if (item.path) {let itemMenu = { path: item.path.replace("/", ""), name: item.name, component: () => import('../views/' + item.pagePath + '.vue'),meta: { title: item.name }}manageRoute.children.push(itemMenu)}})}})// 动态添加到现在的路由对象中去router.addRoute(manageRoute)}}
}// 重置我就再set一次路由
setRoutes()// 路由守卫
router.beforeEach((to, from, next) => {// localStorage.setItem('currentPathName',to.name); // 设置当前的路由名称，为了在Header组件中去使用// store.commit('setPath') // 触发store的数据更新// 未找到路由情况if(!to.matched.length){const storeMenus = localStorage.getItem("menus");if(storeMenus){ // 有菜单没有找到路由，跳转至 404页面next("/404")}else { // // 没有菜单，直接跳转至登录页next("/login")}}// 其他情况next() // 放行路由
})export default router总结
- 动态菜单完结，基本项目也快接近尾声。
