如何在nodejs / nextjs api处理程序中确定http与https

const http = require('http');

const httpServer = http.createServer((req, res) => {
  // 处理HTTP请求
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, HTTP!');
});

const port = 3000;
httpServer.listen(port, () => {
  console.log(`HTTP server is running on port ${port}`);
});

const https = require('https');
const fs = require('fs');

const options = {
  key: fs.readFileSync('privatekey.pem'),
  cert: fs.readFileSync('certificate.pem')
};

const httpsServer = https.createServer(options, (req, res) => {
  // 处理HTTPS请求
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, HTTPS!');
});

const port = 443;
httpsServer.listen(port, () => {
  console.log(`HTTPS server is running on port ${port}`);
});

import { IncomingMessage, ServerResponse } from 'http';
import { NextApiRequest, NextApiResponse } from 'next';

export default function handler(req: NextApiRequest, res: NextApiResponse) {
  if (req.connection.encrypted) {
    // HTTPS请求处理
    res.status(200).json({ message: 'Hello, HTTPS!' });
  } else {
    // HTTP请求处理
    res.status(200).json({ message: 'Hello, HTTP!' });
  }
}
