从文本中提取 URL 的正则表达式 - Ruby
regex to extract URLs from text - Ruby
我正在尝试从文本中检测 urls 并通过用引号引起来替换它们，如下所示：
original text: Hey, it is a url here www.example.com
required text: Hey, it is a url here "www.example.com"
original text 显示我的输入值，required text 代表所需的输出。我在网上搜索了很多但找不到任何可能的解决方案。我已经尝试过 URL.extract 功能，但在没有 http 或 https 的情况下似乎无法检测到 URLs。以下是我要处理的一些网址的示例。如果您知道解决方案，请告诉我。

str.split.select{|w| w[/(\b+\.\w+)/]}
这将为您提供一组没有空格且包含一个或多个 . 个可能适合您的用例的字符的单词。
puts str.split.select{|w| w[/(\b+\.\w+)/]}

已更新
修改字符串的完整解决方案：
str_with_quote = str.clone # make a clone for the `gsub!`
str.split.select{|w| w[/(\b+\.\w+)/]}
.each{|url| str_with_quote.gsub!(url, '"' + url + '"')}
现在您的克隆对象将 url 包含在双引号内
puts str_with_quote
会给你这个输出
