如何将react数据发送到express后台？

import React, { useState } from 'react';
import axios from 'axios';

const MyComponent = () => {
  const [data, setData] = useState('');

  const handleSubmit = async (e) => {
    e.preventDefault();
    try {
      const response = await axios.post('/api/data', { data });
      console.log(response.data);
    } catch (error) {
      console.error(error);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="text"
        value={data}
        onChange={(e) => setData(e.target.value)}
      />
      <button type="submit">Submit</button>
    </form>
  );
};

export default MyComponent;

const express = require('express');
const bodyParser = require('body-parser');

const app = express();
app.use(bodyParser.json());

app.post('/api/data', (req, res) => {
  const { data } = req.body;
  // 处理接收到的数据，例如存储到数据库
  console.log(data);
  res.send('Data received!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
