Facebook Like 按钮如何工作? [英] How does the Facebook Like button work?

问题描述

我想提供一段简单的 Javascript(或 iframe，我猜)，允许 3rd 方将我网站的功能嵌入到他们的网站中.所述小部件的用户已经在我们的网站上通过了身份验证 - 所以基本上 Facebook Like 按钮或 Facebook Connect 是我能找到的最接近的示例.

I want to provide a simple piece of Javascript (or an iframe, I guess) that allows 3rd parties to embed functionality from my site in theirs. The user of said widget will be authenticated on our site already - so basically the Facebook Like button, or Facebook Connect, are the closest examples I could find.

由于 Facebook 有几个不同的按钮，我很难确切地了解它们在做什么.某处是否有简洁的(和技术性的 - 我是一名开发人员，想构建自己的小部件)解释?我特别关注所涉及的安全问题.

Since Facebook has a few different buttons I'm struggling to understand exactly what they're doing though. Is there a succinct (and technical - I'm a developer and want to build my own widget) explanation somewhere? I'm particularly focused on the security issues involved.
