我在我的项目中实现了动态路由，根据用户角色打开不同的页面。https://github.com/javaLuo/react-admin
它在初始加载页面时工作正常。但是，每当我尝试刷新BasicLayout中的任何页面而不是login page时，它都会返回空白页面。
index.js:

import React, { useEffect, useState } from "react";
import { Navigate, BrowserRouter, Routes, Route, Outlet, Router } from 'react-router-dom';
import { createHashHistory as createHistory} from "history";
import { connect} from "react-redux";
import tools from "../util/tools";
import BasicLayout from "../layouts/BasicLayout";
import UserLayout from "../layouts/UserLayout";

const history = createHistory();
    
const RouterContainer = (props) => {
  useEffect(() => {
    const userinfo = localStorage.getItem("userinfo");
    if(userinfo){
      props.setUserInfo(JSON.parse(userinfo));
    }
  },[]);

  const onEnter = (Component, props) => {
    const userinfo = localStorage.getItem("userinfo");
    if (userinfo) {
      return <Component {...props} />;
    }
    return <Navigate to="/public/login"/>;
  };

  return (
    <BrowserRouter history={history}>
      <Routes>
        <Route path="/public/*" element={<UserLayout />} />
        <Route path="/*" element={onEnter(BasicLayout, props)}/> 
      </Routes>
    </BrowserRouter>
  );
};

export default connect(
  (state) => ({
    userinfo: state.app.userinfo,
  }),
  (dispatch) => ({
    setUserInfo: dispatch.app.setUserInfo,
  })
)(RouterContainer);

如果localeStorage中没有登录记录，则onEnter函数将重定向到登录页面。
BasicLayout.js
