有没有办法混淆 Rails 3 中的数据，以便只有网络访问者（而不是屏幕抓取者）才能查看数据？
我在 Rails 3 应用程序中有一些分层数据。它允许用户快速深入了解数据集。我想通过某种基于 JS 的混淆来防止人们成功地针对该网站运行机器人。以前有人这样做过吗？
I have some hierarchical data in a Rails 3 applications. It allows the user to quickly drill down into the data set. I would like to prevent people from running bots successfully against this site with some sort of JS-based obfuscation. Has anyone done this before?

Rails 有一个用于电子邮件地址的混淆助手实例。它可能会给你一些想法..

我想你也可以使用Flash..众所周知，这对蜘蛛来说很难理解。但总的来说，这是一个失败的提议。

Rails has one instance of an obfuscation helper for use with email addresses. It might give you some ideas..

I suppose you could use Flash too.. That's notoriously hard for spiders to grok. In general though this is a losing proposition.

我决定在这里做的是添加一些东西来检测来自特定 IP 地址的每分钟请求，然后自动将该 IP 列入黑名单（将它们重定向到“您已被列入黑名单页面并将其 IP 保存在黑名单表中）”超过了可配置的数量，我在第一晚就捕获了 GoogleBot，然后也设置了一个白名单。
What I decided to do here was to put in something that detects requests per minute from a specific IP address, then automatically blacklist that IP (redirect them to a "you've been blacklisted page and save their IP in a blacklists table) if they exceed a configurable amount. I caught the GoogleBot the first night and then set up a whitelist as well.
