1.switch被廢棄券盅，使用routes替代
2.嵌套路由使用< Outlet />
3.跳轉(zhuǎn)方式改變冈钦，新增hook useNavigate/useLocation/useRoutes等

v6自動生成路由

import React,{useState} from "react";
import { BrowserRouter as Router, Routes, Route, Navigate } from "react-router-dom";

import Home from "../pages/home";
import Error from "../pages/404";
const CollectRouter = ({ routes }) => {
  const [userInfo,setuserInfo] = useState(auth.getUser() || '');
  const initRoute = (routeArray) =>
    routeArray.map((v) => (
      <Route
        path={v.path}
        key={v.path}
          element={userInfo || v.path ==='/login'?<v.element />:<Navigate to='/login' replace />}
        children={v.children && initRoute(v.children)}
      />
     //注意這里的element以及children，值與5不同，嵌套路由方式升級
    )
  );
  return (
    <Router>
//switch廢棄，改用routes
      <Routes>
        <Route path="/" element={userInfo?<Home />:<Navigate to='/login' replace />} />
        {initRoute(routes)}
        <Route path="*" element={<Error />} />
      </Routes>
    </Router>
  );
};

export default CollectRouter;

自動讀取文件毙石，并講page下的文件自動生成路由樹 （待優(yōu)化）

let context = require.context('../pages', true, /\.js$/);
let paths = context.keys();
let routes = paths.map(d => {
  return {
    path: d.substr(1).replace(/(\/index\.js|\.js)$/, ""),
    element: context(d).default,
  }
})

function getRouteTree(routes) {
  routes.forEach(el => {
    let _path = el.path.substr(1).split('/');
    if (_path.length <= 1) {
      el.id = _path.join('');
    } else {
      // el.path = _path.slice(-1)[0];
      el.id = _path.join('/');
      _path.pop();
      el.parent_id = _path.join('/');
    }
  });
  let tree = [];
  routes.forEach(el => {
    if (el.element.params) { el.path = el.path + el.element.params }
    if (el.parent_id) {
      let target = routes.find(v => v.id === el.parent_id);
      if (!target.children) {
        target.children = []
      }
      target.children.push(el)
    } else {
      tree.push(el)
    }
  })
  return tree
}

export default getRouteTree(routes)
