Ruby: Extract the hostname from a URL
url = 'http://www.foocorp.com/foo/bar'
URI.parse(url).host
# => www.foocorp.com
Note that this will raise an error if the given argument is not a URL.
If you need the host's full URL without path, query, fragment etc., use
URI.join
Show archive.org snapshot
with a clever twist:
url = 'http://www.foocorp.com:33546/foo/bar?query=foobar#hash'
URI.join url, '/'
# => http://www.foocorp.com:33546/
