如何从reactjs向nodejs发送表单

import React, { useState } from 'react';

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

  const handleSubmit = async (e) => {
    e.preventDefault();
    
    try {
      const response = await fetch('/submit-form', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify(formData),
      });
      
      if (response.ok) {
        // 处理成功响应
      } else {
        // 处理失败响应
      }
    } catch (error) {
      // 处理错误
    }
  };

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

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

export default FormComponent;

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

const app = express();

app.use(bodyParser.json());

app.post('/submit-form', (req, res) => {
  const formData = req.body;
  
  // 处理表单数据
  // ...

  // 返回响应
  res.sendStatus(200);
});

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