What is a good way to get the filename from a URL in Ruby?

Question

require 'uri'

url = 'http://www.example.com/foo/bar/filename.jpg?2384973948743'

uri = URI.parse(url)

puts File.basename(uri.path)

#=> filename.jpg

If you do not expect query_string in url, you can simply use File.basename

puts File.basename('http://example.com/folder1/folder2/file.txt')

This displays file.txt

The easiest way is probably to use URI.parse

url_object = URI.parse([my url])
url_path = url_object.path
filename = url_path.split("/").last
