这很容易用JavaScript实现。将此放置在页面底部，就在</body> 标签

这将附加?pp=my-affiliate-id 在链接的末尾。只需更改变量aid 以下值：

<script>
// Change "my-affiliate-id" below to your actual affiliate id
const aid = \'my-affiliate-id\';

// Append slash with affiliate id, only if an affiliate ID is not found in the link yet
const goglinks = document.querySelectorAll(\'a[href*="gog.com"]\');
goglinks.forEach(function(el) {
  if(!el.href.includes(\'pp=\')) {
    el.href = el.href.replace(/\\?.*$/, \'\') + \'?pp=\' + aid
  }
})
</script>
