正则表达式 - 查找推文中的所有链接 [英] Regex - find all links in a tweet

问题描述

我的正则表达式很差，让我失望，所以在这里提供一些帮助会很棒.

My regex is poor and letting me down so some help would be great here.

我想要做的就是返回出现在推文中的所有链接(只是一个字符串)——一些例子是:

All I want to do is return all the links which appear in a tweet (just a string) - Some examples are:

"很棒的总结 http://mytest.com/blog/post.html (#test)

"http://mytest.com/blog/post.html (#test)

帖子:http://mytest.com/blog/post.html"

它还应该支持多个链接，例如:阅读 http://mytest.com/blog/post.html 和 http://mytest.com/blog/post_two.html"

It should also support multiple links like: "read http://mytest.com/blog/post.html and http://mytest.com/blog/post_two.html"

任何帮助都会很棒！

谢谢

推荐答案

试试这个:

/\bhttps?:\/\/\S+\b/

更新:

捕捉以www"开头的链接.也是(没有http://"前缀)，你可以试试这个:

To catch links beginning with "www." too (no "http://" prefix), you could try this:

/\b(?:https?:\/\/|www\.)\S+\b/
