企业出行服务系统怎么创建

import React, { useState } from 'react';

function RegisterForm() {
  const [formData, setFormData] = useState({
    username: '',
    email: '',
    password: ''
  });

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

  const handleSubmit = (e) => {
    e.preventDefault();
    // 这里可以添加API调用进行用户注册
    console.log(formData);
  };

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" name="username" placeholder="Username" onChange={handleChange} required />
      <input type="email" name="email" placeholder="Email" onChange={handleChange} required />
      <input type="password" name="password" placeholder="Password" onChange={handleChange} required />
      <button type="submit">Register</button>
    </form>
  );
}

export default RegisterForm;

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

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

app.post('/register', async (req, res) => {
  const { username, email, password } = req.body;
  
  // 密码加密
  const hashedPassword = await bcrypt.hash(password, 10);

  // 这里可以添加数据库操作保存用户信息
  console.log({ username, email, hashedPassword });

  res.status(201).send('User registered successfully');
});

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