如何将React表单中的数据插入到mysql？

import React, { useState } from 'react';

const Form = () => {
  const [formData, setFormData] = useState({
    name: '',
    email: '',
    message: ''
  });

  const handleChange = (e) => {
    setFormData({ ...formData, [e.target.name]: e.target.value });
  };

  const handleSubmit = (e) => {
    e.preventDefault();
    fetch('/api/insertData', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(formData)
    })
      .then(response => response.json())
      .then(data => {
        console.log(data);
        // 处理成功插入数据后的逻辑
      })
      .catch(error => {
        console.error(error);
        // 处理错误情况
      });
  };

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" name="name" value={formData.name} onChange={handleChange} />
      <input type="email" name="email" value={formData.email} onChange={handleChange} />
      <textarea name="message" value={formData.message} onChange={handleChange} />
      <button type="submit">提交</button>
    </form>
  );
};

export default Form;

const express = require('express');
const mysql = require('mysql2');

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

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'your_mysql_username',
  password: 'your_mysql_password',
  database: 'your_database_name'
});

app.post('/api/insertData', (req, res) => {
  const { name, email, message } = req.body;
  const sql = 'INSERT INTO your_table_name (name, email, message) VALUES (?, ?, ?)';
  const values = [name, email, message];

  connection.query(sql, values, (error, results) => {
    if (error) {
      console.error(error);
      res.status(500).json({ message: '插入数据时发生错误' });
    } else {
      res.json({ message: '数据插入成功' });
    }
  });
});

app.listen(3000, () => {
  console.log('服务器已启动');
});
