使用 robots.txt 阻止 AI 爬虫，给服务器“减负”

时间：2026-04-09 08:44:00 来源：作者：

最近辣鸡轻量服务器资源频频飙红，开始还以为流量暴涨，自己要发了。

结果一看日志——原来是每天被各种AI爬虫轮番“光顾”，资源被薅到见底……

如何礼貌地拒绝这些不请自来的“访客”呢？

这时， robots.txt 文件就可以派上用场了。

什么是 robots.txt？
robots.txt 是放置在网站根目录下的一个文本文件，用于向网络爬虫和机器人传达抓取规则。通过它，你可以指定哪些内容允许被抓取，哪些应被禁止访问。

需要注意的是，尽管大多数正规机器人会遵守 robots.txt 中的规则，但某些恶意爬虫可能会无视这些限制，仍需结合其他防护手段。

如何阻止特定爬虫？
你可以在 robots.txt 中使用如下指令：
Bash
User-agent: [爬虫名称]
Disallow: /

针对常见AI机器人的屏蔽清单，以下是一份实用的 robots.txt 示例，可用于限制部分AI爬虫访问：
