💡 应用建议:动态路由适合需要灵活权限控制和模块化管理的复杂应用
addRoute是Vue Router 4提供的动态添加路由的核心方法:
// 🎉 动态添加路由基础示例
import { createRouter, createWebHistory } from 'vue-router';
const router = createRouter({
history: createWebHistory(),
routes: [
{
path: '/',
name: 'Home',
component: () => import('@/views/Home.vue')
}
]
});
// 1. 添加顶级路由
router.addRoute({
path: '/about',
name: 'About',
component: () => import('@/views/About.vue'),
meta: { title: '关于我们' }
});
// 2. 添加嵌套路由
router.addRoute('Home', {
path: 'news',
name: 'News',
component: () => import('@/views/News.vue')
});
// 3. 批量添加路由
const dynamicRoutes = [
{
path: '/products',
name: 'Products',
component: () => import('@/views/Products.vue')
},
{
path: '/services',
name: 'Services',
component: () => import('@/views/Services.vue')
}
];
dynamicRoutes.forEach(route => {
router.addRoute(route);
});
export default router;// 动态删除路由示例
// 1. 通过路由名称删除
router.removeRoute('About');
// 2. 通过addRoute返回的删除函数
const removeRoute = router.addRoute({
path: '/temp',
name: 'Temp',
component: TempComponent
});
// 稍后删除路由
removeRoute();
// 3. 批量删除路由
const routesToRemove = ['Products', 'Services', 'Contact'];
routesToRemove.forEach(routeName => {
if (router.hasRoute(routeName)) {
router.removeRoute(routeName);
}
});
// 4. 检查路由是否存在
if (router.hasRoute('Admin')) {
console.log('Admin路由存在');
} else {
console.log('Admin路由不存在');
}
// 5. 获取所有路由
const allRoutes = router.getRoutes();
console.log('当前所有路由:', allRoutes);权限驱动的动态路由通过用户权限数据动态生成可访问的路由配置:
// 🎉 权限路由管理器示例
class PermissionRouteManager {
constructor(router) {
this.router = router;
this.dynamicRoutes = new Set();
this.routeModules = new Map();
}
// 注册路由模块
registerModule(moduleName, routes) {
this.routeModules.set(moduleName, routes);
}
// 根据权限生成路由
async generateRoutes(userPermissions, userRoles) {
// 清除之前的动态路由
this.clearDynamicRoutes();
// 获取所有可用路由模块
const availableRoutes = this.getAvailableRoutes(userPermissions, userRoles);
// 动态添加路由
for (const route of availableRoutes) {
this.addDynamicRoute(route);
}
return availableRoutes;
}
// 获取可用路由
getAvailableRoutes(permissions, roles) {
const availableRoutes = [];
for (const [moduleName, routes] of this.routeModules) {
const filteredRoutes = this.filterRoutesByPermission(routes, permissions, roles);
availableRoutes.push(...filteredRoutes);
}
return availableRoutes;
}
// 根据权限过滤路由
filterRoutesByPermission(routes, permissions, roles) {
return routes.filter(route => {
// 检查角色权限
if (route.meta?.roles) {
const hasRole = route.meta.roles.some(role => roles.includes(role));
if (!hasRole) return false;
}
// 检查具体权限
if (route.meta?.permissions) {
const hasPermission = route.meta.permissions.every(permission =>
permissions.includes(permission)
);
if (!hasPermission) return false;
}
// 递归处理子路由
if (route.children) {
route.children = this.filterRoutesByPermission(route.children, permissions, roles);
}
return true;
});
}
// 添加动态路由
addDynamicRoute(route) {
const removeRoute = this.router.addRoute(route);
this.dynamicRoutes.add({
name: route.name,
removeFunction: removeRoute
});
}
// 清除动态路由
clearDynamicRoutes() {
for (const routeInfo of this.dynamicRoutes) {
if (routeInfo.removeFunction) {
routeInfo.removeFunction();
} else if (routeInfo.name) {
this.router.removeRoute(routeInfo.name);
}
}
this.dynamicRoutes.clear();
}
// 重新加载路由
async reloadRoutes(userPermissions, userRoles) {
await this.generateRoutes(userPermissions, userRoles);
// 如果当前路由不再可访问,重定向到首页
const currentRoute = this.router.currentRoute.value;
if (!this.router.hasRoute(currentRoute.name)) {
this.router.push('/');
}
}
}
// 使用权限路由管理器
const routeManager = new PermissionRouteManager(router);
// 注册路由模块
routeManager.registerModule('admin', [
{
path: '/admin',
name: 'Admin',
component: () => import('@/views/admin/Layout.vue'),
meta: {
title: '管理后台',
roles: ['admin'],
icon: 'admin'
},
children: [
{
path: 'users',
name: 'AdminUsers',
component: () => import('@/views/admin/Users.vue'),
meta: {
title: '用户管理',
permissions: ['admin:users:read']
}
},
{
path: 'settings',
name: 'AdminSettings',
component: () => import('@/views/admin/Settings.vue'),
meta: {
title: '系统设置',
permissions: ['admin:settings:read']
}
}
]
}
]);
routeManager.registerModule('user', [
{
path: '/profile',
name: 'Profile',
component: () => import('@/views/user/Profile.vue'),
meta: {
title: '个人资料',
roles: ['user', 'admin']
}
}
]);// 🎉 用户登录后路由初始化示例
import { useUserStore } from '@/stores/user';
// 在用户登录成功后初始化路由
async function initializeUserRoutes() {
const userStore = useUserStore();
try {
// 获取用户信息和权限
await userStore.fetchUserInfo();
const { permissions, roles } = userStore.user;
// 生成动态路由
const availableRoutes = await routeManager.generateRoutes(permissions, roles);
console.log('用户可访问路由:', availableRoutes);
// 更新菜单数据
updateMenuData(availableRoutes);
return availableRoutes;
} catch (error) {
console.error('初始化用户路由失败:', error);
throw error;
}
}
// 在路由守卫中使用
router.beforeEach(async (to, from, next) => {
const userStore = useUserStore();
if (userStore.isLoggedIn && !userStore.routesInitialized) {
try {
await initializeUserRoutes();
userStore.routesInitialized = true;
// 重新导航到目标路由
next({ ...to, replace: true });
} catch (error) {
// 初始化失败,重定向到登录页
next('/login');
}
} else {
next();
}
});权限驱动路由的核心优势:
💼 实际应用场景:企业管理系统、多角色平台、SaaS应用等需要精细权限控制的系统
// 🎉 动态路由参数高级应用示例
class DynamicRouteHandler {
constructor(router) {
this.router = router;
this.paramRoutes = new Map();
}
// 添加参数化路由
addParameterizedRoute(pattern, componentResolver) {
const routeConfig = {
path: pattern,
name: `dynamic-${Date.now()}`,
component: componentResolver,
beforeEnter: (to, from, next) => {
// 验证参数
if (this.validateRouteParams(to.params, pattern)) {
next();
} else {
next({ name: 'NotFound' });
}
}
};
const removeRoute = this.router.addRoute(routeConfig);
this.paramRoutes.set(pattern, {
config: routeConfig,
removeFunction: removeRoute
});
return removeRoute;
}
// 验证路由参数
validateRouteParams(params, pattern) {
// 根据路由模式验证参数
const paramNames = this.extractParamNames(pattern);
for (const paramName of paramNames) {
const value = params[paramName];
// 根据参数名称进行特定验证
if (!this.validateParam(paramName, value)) {
return false;
}
}
return true;
}
// 提取参数名称
extractParamNames(pattern) {
const matches = pattern.match(/:(\w+)/g);
return matches ? matches.map(match => match.slice(1)) : [];
}
// 验证单个参数
validateParam(paramName, value) {
const validators = {
id: (val) => /^\d+$/.test(val),
slug: (val) => /^[a-z0-9-]+$/.test(val),
category: (val) => ['tech', 'business', 'lifestyle'].includes(val),
userId: (val) => /^[a-f0-9-]{36}$/.test(val) // UUID格式
};
const validator = validators[paramName];
return validator ? validator(value) : true;
}
// 动态生成内容路由
generateContentRoutes(contentTypes) {
contentTypes.forEach(type => {
// 列表页路由
this.addParameterizedRoute(`/${type.slug}`, () =>
import(`@/views/content/${type.component}List.vue`)
);
// 详情页路由
this.addParameterizedRoute(`/${type.slug}/:id(\\d+)`, () =>
import(`@/views/content/${type.component}Detail.vue`)
);
// 分类页路由
if (type.hasCategories) {
this.addParameterizedRoute(`/${type.slug}/category/:category`, () =>
import(`@/views/content/${type.component}Category.vue`)
);
}
});
}
}
// 使用动态路由处理器
const routeHandler = new DynamicRouteHandler(router);
// 根据CMS配置生成内容路由
const contentTypes = [
{
slug: 'articles',
component: 'Article',
hasCategories: true
},
{
slug: 'products',
component: 'Product',
hasCategories: true
},
{
slug: 'events',
component: 'Event',
hasCategories: false
}
];
routeHandler.generateContentRoutes(contentTypes);// 路由缓存和预加载管理
class RouteCache {
constructor() {
this.componentCache = new Map();
this.preloadQueue = new Set();
}
// 缓存组件
cacheComponent(routeName, component) {
this.componentCache.set(routeName, component);
}
// 获取缓存的组件
getCachedComponent(routeName) {
return this.componentCache.get(routeName);
}
// 预加载路由组件
async preloadRoute(routePath) {
if (this.preloadQueue.has(routePath)) {
return;
}
this.preloadQueue.add(routePath);
try {
const route = router.resolve(routePath);
if (route.matched.length > 0) {
const component = route.matched[0].components?.default;
if (typeof component === 'function') {
await component();
}
}
} catch (error) {
console.warn('预加载路由失败:', routePath, error);
}
}
// 批量预加载
async batchPreload(routePaths) {
const promises = routePaths.map(path => this.preloadRoute(path));
await Promise.allSettled(promises);
}
}
const routeCache = new RouteCache();
// 在路由变化时进行预加载
router.afterEach((to) => {
// 预加载相关路由
const relatedRoutes = getRelatedRoutes(to.path);
routeCache.batchPreload(relatedRoutes);
});
function getRelatedRoutes(currentPath) {
// 根据当前路径推测用户可能访问的路由
const related = [];
if (currentPath.startsWith('/admin')) {
related.push('/admin/users', '/admin/settings');
} else if (currentPath.startsWith('/user')) {
related.push('/user/profile', '/user/orders');
}
return related;
}通过本节Vue Router动态路由详解的学习,你已经掌握:
A: 适量的动态路由不会显著影响性能,但大量动态路由可能影响路由匹配速度,建议合理设计路由结构。
A: 是的,动态路由在页面刷新后会丢失,需要在应用初始化时重新添加。
A: 可以添加通配符路由作为兜底,或者在路由守卫中处理未匹配的路由。
A: 可以,动态路由支持嵌套结构,可以动态添加父路由和子路由。
A: 可以使用router.getRoutes()查看当前所有路由,使用Vue DevTools监控路由变化。
