How to extract URLs from text

Question

How do I extract all URLs from a plain text file in Ruby?

I tried some libraries but they fail in some cases. What\'s the best way?

You can use regex and .scan()

string.scan(/(https?:\/\/([-\w\.]+)+(:\d+)?(\/([\w\/_\.]*(\?\S+)?)?)?)/)

You can get started with that regex and adjust it according to your needs.
