# 网站 robots.txt User-agent Disallow 参考示例


网站通过设置 robots.txt 禁止一些爬虫。robots.txt 几个可参考示例。

## 缘起


之前看了篇文，goodboyboy 的 [Facebook 爬虫造成的高占用问题](https://blog.goodboyboy.top/posts/1911030434.html) 。而且爬的是自建 Gitea 的 commit 。最后通过屏蔽海外 IP 实现的禁爬。

我以前搭建过 Chevereto 图床，被爬虫搞的服务器资源占满。谷歌的爬虫各种参数排列组合去爬。Chevereto 自带多语言，爬虫每种语言都试一遍。有些爬虫也会爬图片，用于生成略缩图。之前必应搜索看到我博客里的图片了，甚至会收录文章中引用的 JSON 文件。

话说回来，通常做法是写 robots.txt 。这个文件可确保像对搜索引擎没有任何意义的 API 端点等等不会被搜索引擎索引，或者禁止部分路径，UA 爬取，或其他限制。

本文主要提供 UA 列表，作为备忘和参考。

Hugo Theme Doit https://github.com/HEIGE-PCloud/DoIt/blob/main/layouts/robots.txt 

禁止了几个营销公司的爬虫，有些据说是监视版权之类的。

以及 Internet Archive 用的 Heritrix 默认 UA。注意 Internet Archive 网站实际使用的是 archive.org_bot 等 UA。

## 总结

众所周知，许多爬虫会忽略 robots.txt 中的条目。此时，可考虑在反向代理处配置过滤 UA 等方法。
