是否可以从 Cloudflare worker 重定向脚本中排除搜索机器人（如 Google）？

Question

我使用 Cloudflare worker 将访问者重定向到正确的网站版本，如下所示：

addEventListener('fetch', event => {
    event.respondWith(handleRequest(event.request))
  })

  /**
   * Respond to the request
   * @param {Request} request
   */
  async function handleRequest(request) {
    country_code = request.headers.get('CF-IPCountry');
    var link;

  switch(request.headers.get('CF-IPCountry')) {
    case 'TW':  // Taiwan
    link = "https://www.website.com/twn";
        break;
    case 'TH':  // Thailand
    link = "https://www.website.com/tha";
        break;
    case 'GB':  // United Kingdom
    link = "https://www.website.com/gbr";
        break;
    case 'US':  // United States
    link = "https://www.website.com/us";
        break;
    default:
      link = "https://www.website.com/rotw" // Rest of the world
  }

  return new Response('', {
          status: 301,
          headers: {
            'Location': link
          }
        })
  }

问题是 Google 漫游器被重定向到网站。com/us 因此我的 Google 入口将访问者直接指向 /us 网站。有没有办法从国家/地区重定向脚本中排除搜索机器人并将它们直接路由到 website.com 而不是网站。com/countrycode?

你能做这样的事情吗？我还没有测试过这个。

addEventListener('fetch', event => {
    event.respondWith(handleRequest(event.request))
  })

  /**
   * Respond to the request
   * @param {Request} request
   */
  async function handleRequest(request) {
    country_code = request.headers.get('CF-IPCountry');
    var link;

  let userAgent = request.headers.get('User-Agent') || ''
  if (userAgent.includes('Googlebot')) {
    return new Response('', {
          status: 301,
          headers: {
            'Location': "https://www.website.com/"
          }
        })
  }

  switch(request.headers.get('CF-IPCountry')) {
    case 'TW':  // Taiwan
    link = "https://www.website.com/twn";
        break;
    case 'TH':  // Thailand
    link = "https://www.website.com/tha";
        break;
    case 'GB':  // United Kingdom
    link = "https://www.website.com/gbr";
        break;
    case 'US':  // United States
    link = "https://www.website.com/us";
        break;
    default:
      link = "https://www.website.com/rotw" // Rest of the world
  }

  return new Response('', {
          status: 301,
          headers: {
            'Location': link
          }
        })
  }

Is it possible to exclude search bots (like Google) from Cloudflare worker redirect script?
