如何阻止来自中国的请求？

我有一个比较流行的 API（每天 10,000 多个请求）。每天从某个 IP 地址发出 10 个请求后，我会返回一条消息，告诉用户如果想更多地使用该服务，则需要支付一些现金。

今天早上，我发现我的网络服务运行速度非常慢。我检查了数据库，发现我收到了来自中国 IP 地址的垃圾邮件。他们会使用一个 IP 地址 10 次，然后递增最后一个八位字节。悲伤的时刻。

为了保持系统的活力，我想限制或完全切断来自中国的请求。最好的方法是什么？在 PHP 中按国家/地区代码进行地理查找每个请求和禁令？这似乎是一种低效的方式。我在 htaccess 级别无能为力，是吗？

只需屏蔽整个中国IP范围即可： 在 .htaccess 中
