自从我访问的几乎所有网站都弹出有关 cookie 等的消息以来，已经有一段时间了。我一直不明白为什么，但不知不觉中，我总是点击“确定”。
由于担心这可能会干扰我使用的 Google AdSense、YouTube、Vimeo 甚至 Facebook（评论插件），我试图了解更多，甚至不给出任何未获得报酬的借口（如果适用）。然后，我大致上阅读了我最关心的部分（因为我没有联系表格或用户注册）“除非授权的 cookie 不得记录在用户的浏览器中”。
但是，如果我的网站是静态的，使用 Hugo 生成重要的东西，那么在底部或全屏叠加层添加横幅有什么好处呢？用户可以同意，但我无法知道他们是否同意，因为它是静态的，只有 HTML/JS/CSS，没有数据库，对吗？我的意思是，我怎么能存储这个用户偏好？

由于这个社区在没有代码的情况下关闭（有时是拒绝投票和逃避）主题的政策有时是不可接受的——比如如果概念性问题是完全完全错误的——并且考虑到一些成员对此事的兴趣，正如所承诺的那样，我我编写了一个非常基本的示例：

这有点……荒谬，严肃，不得不写一个 cookie 只是为了说你不会写任何 cookie。oO
无论如何......这是一个非常基本的实现，标记和样式从 Stack Overflow 自己的消息中借用 - 每次清除 cookie 时都会显示，即使在这里关闭消息时会发出 AJAX 请求来更新用户帐户，这不应该再次为同一用户显示消息，毕竟他/她之前已经接受了。
该例程使用js-cookie 的Cookie 操作代码（此处由JSCompress混淆）读取 cookie 的值，如果没有找到它，则显示接受消息，或者如果用户先前同意，则在任何时候以非常明确的方式不同意 GDPR — 即使用户尚未同意，也不会阻止任何内容。
这段代码可能在这里不起作用。我必须启动我的 PHP 内置网络服务器才能以http而不是file:///的形式访问它
