Question

我想在rails应用程序中显示用户的活动供稿。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haml中原始从 github_feed.entries 呈现每个条目的内容时，链接会执行不包含域 https://github.com/ ，但仅包含路径。这会导致问题，即UI上的呈现链接包含应用程序域而不是github。我们如何解决这个问题？

Answer 1

由于github atom feeds为内容提供了相对url，你可能想用绝对引用替换它们。

这可以通过

完成

^((?:\s*\d{1,3}[wW]\s*)?(?:\s+\d{1,3}[dD]\s*)?(?:\s+\d{1,3}[hH]\s*)?(?:\s+\d{1,3}[mM]\s*)?(?:\s+\d{1,3}[sS]\s*)?)$

然后替换你的：

 NSPredicate *predicate = [NSPredicate predicateWithFormat: @"compositeName CONTAINS[c] %@", searchText];

与

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

Github活动供稿网址不包含域
