如何在Next.js中添加301重定向(从http到https )？

const { createServer } = require('http');
const { parse } = require('url');
const next = require('next');

const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });
const handle = app.getRequestHandler();

app.prepare().then(() => {
  createServer((req, res) => {
    const parsedUrl = parse(req.url, true);
    const { pathname, query } = parsedUrl;

    // 检查是否为HTTP请求
    if (req.headers['x-forwarded-proto'] === 'http') {
      // 重定向到HTTPS
      res.writeHead(301, {
        Location: `https://${req.headers.host}${pathname}${query}`
      });
      res.end();
    } else {
      // 处理其他请求
      handle(req, res, parsedUrl);
    }
  }).listen(3000, (err) => {
    if (err) throw err;
    console.log('> Ready on http://localhost:3000');
  });
});
