React-router如何重定向到Express GET

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

function MyComponent() {
  // 根据某些条件决定是否重定向
  const shouldRedirect = true;

  if (shouldRedirect) {
    return <Redirect to="/express-route" />;
  }

  return (
    <div>
      {/* 其他内容 */}
    </div>
  );
}

const express = require('express');
const app = express();

app.get('/express-route', (req, res) => {
  res.send('这是由 Express 处理的页面');
});

app.listen(3000, () => {
  console.log('服务器运行在 http://localhost:3000');
});

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

function MyComponent() {
  const history = useHistory();

  function handleClick() {
    history.push('/express-route');
  }

  return (
    <button onClick={handleClick}>跳转到 Express 页面</button>
  );
}
