我想在 Rails 应用程序中显示用户的活动提要。我正在使用 feedjira。

2.2.4 :006 > xml_feed = Feedjira::Feed.fetch_raw "https://github.com/prasadsurase.atom"
2.2.4 :006 > github_feed = Feedjira::Feed.parse xml_feed
2.2.4 :006 > github_feed.entries.first.content

在将 haml 中 github_feed.entries 中的每个条目的内容呈现为raw时，链接不包含域https://github.com/，而仅包含路径。这会导致问题，例如 UI 上呈现的链接包含应用程序域而不是 github。我们如何解决这个问题？

由于 github atom feeds 为内容提供了相对 url，您可能希望将它们替换为绝对引用。

这可以通过

gsub( %r{<a href=\"/},'<a href="https://github.com/')

从而替换您的：

2.2.4 :006 > github_feed.entries.first.content

和

2.2.4 :006 > github_feed.entries.first.content.gsub( %r{<a href=\"/},'<a href="https://github.com/')
