react如何动态添加路由

动态添加路由的实现方法

在React中动态添加路由通常结合React Router库实现。以下是几种常见场景的解决方案：

使用React Router v6实现动态路由

React Router v6提供了useRoutes钩子和动态路由配置能力：

import { useRoutes } from 'react-router-dom';

function App() {
  const routes = useRoutes([
    { path: '/', element: <Home /> },
    { path: '/users', element: <Users /> },
    // 动态添加的其他路由...
  ]);

  return routes;
}

基于权限的动态路由加载

根据用户权限动态生成路由配置：

function App() {
  const [routes, setRoutes] = useState([]);

  useEffect(() => {
    fetchUserPermissions().then(permissions => {
      const dynamicRoutes = generateRoutesBasedOnPermissions(permissions);
      setRoutes(dynamicRoutes);
    });
  }, []);

  return useRoutes([
    { path: '/', element: <PublicPage /> },
    ...routes
  ]);
}

懒加载路由组件

结合React的lazy和Suspense实现路由组件的动态加载：

const AdminPanel = React.lazy(() => import('./AdminPanel'));

function App() {
  return (
    <Routes>
      <Route path="/admin" element={
        <Suspense fallback={<Loading />}>
          <AdminPanel />
        </Suspense>
      } />
    </Routes>
  );
}

路由配置化方案

将路由配置提取为独立模块便于管理：

// routes.js
export const publicRoutes = [
  { path: '/', element: <Home /> }
];

export const privateRoutes = [
  { path: '/dashboard', element: <Dashboard /> }
];

// App.js
function App() {
  const [allRoutes, setAllRoutes] = useState(publicRoutes);

  useEffect(() => {
    if (userLoggedIn) {
      setAllRoutes([...publicRoutes, ...privateRoutes]);
    }
  }, [userLoggedIn]);

  return useRoutes(allRoutes);
}

路由守卫实现

在动态路由中添加权限验证层：

function PrivateRoute({ element, ...rest }) {
  const auth = useAuth();
  return auth ? element : <Navigate to="/login" />;
}

// 动态路由配置
const dynamicRoutes = [
  { 
    path: '/profile', 
    element: <PrivateRoute element={<Profile />} /> 
  }
];

服务端控制路由

从服务端获取路由配置的实现方式：

async function fetchRoutes() {
  const response = await fetch('/api/routes');
  return response.json();
}

function App() {
  const [routes, setRoutes] = useState([]);

  useEffect(() => {
    fetchRoutes().then(serverRoutes => {
      const formattedRoutes = serverRoutes.map(route => ({
        path: route.path,
        element: React.createElement(components[route.component])
      }));
      setRoutes(formattedRoutes);
    });
  }, []);

  return useRoutes(routes);
}
