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

const app = express();
const port = 3000;

// 使用 body-parser 中间件解析 JSON 数据
app.use(bodyParser.json());

// 处理 POST 请求
app.post('/api/data', (req, res) => {
  const data = req.body;
  console.log('Received data:', data);
  res.status(200).send('Data received successfully');
});

app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}`);
});

app.use(bodyParser.json());
// 或者对于表单数据
app.use(bodyParser.urlencoded({ extended: true }));

const cors = require('cors');
app.use(cors());

const Joi = require('joi');

const schema = Joi.object({
  username: Joi.string().required(),
  email: Joi.string().email().required(),
});

app.post('/api/user', (req, res) => {
  const { error } = schema.validate(req.body);
  if (error) {
    return res.status(400).send(error.details[0].message);
  }
  // 处理数据
