//router.js
import React, { lazy } from react;
import { Navigate } from react-router-domconst Error lazy(() import(/pages/Error/Error.jsx))
const Index lazy(() import(/pages/Index/Index.jsx))
const Login lazy(() import(/pages/Login/Login.jsx))export const routes [{path: /,element: Navigate to/index/},{path: /login,element: Login /},{path: /index,element: Index /},{path: *,element: Error /},
]
import React, { useEffect, Suspense } from react
import { useRoutes, useNavigate } from react-router-dom
import { routes } from ./routerexport default function Index() {const element useRoutes(routes)return (Authen route{element} children{element.children}Suspensediv{element}/div/Suspense/Authen)}
//实现路由拦截
const Authen (props) {const navigate useNavigate()const { route, children } propsconst username sessionStorage.getItem(username)console.log(props);useEffect(() {if (route.props.match.pathname /login username) {navigate(/index)}}, [route, navigate,username])return children
}
Surpense组件是react组件懒加载的时候路由跳转了由于网络原因组件内容无法及时过去不添加会报错。
