node-http-proxy，如何向初始请求传递新的查询参数？

const httpProxy = require('http-proxy');
const proxy = httpProxy.createProxyServer();

proxy.on('proxyReq', function(proxyReq, req, res, options) {
  // 获取原始请求的URL
  const originalUrl = req.url;

  // 添加新的查询参数
  const newQueryParams = 'newParam=value';
  const newUrl = originalUrl + (originalUrl.includes('?') ? '&' : '?') + newQueryParams;

  // 修改代理请求的URL
  proxyReq.path = newUrl;
});

const targetUrl = 'http://target-server.com';
const proxyPort = 3000;

proxy.web(req, res, { target: targetUrl });

proxy.listen(proxyPort, function() {
  console.log('Proxy server is listening on port ' + proxyPort);
});
