require 'uri'

URI

URI is a module providing classes to handle Uniform Resource Identifiers (RFC2396).

Features

  • Uniform way of handling URIs.
  • Flexibility to introduce custom URI schemes.
  • Flexibility to have an alternate URI::Parser (or just different patterns and regexp’s).

Basic example

require 'uri'

uri = URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
#=> #<URI::HTTP http://foo.com/posts?id=30&limit=5#time=1305298413>

uri.scheme    #=> "http"
uri.host      #=> "foo.com"
uri.path      #=> "/posts"
uri.query     #=> "id=30&limit=5"
uri.fragment  #=> "time=1305298413"

uri.to_s      #=> "http://foo.com/posts?id=30&limit=5#time=1305298413"

Adding custom URIs

module URI
  class RSYNC < Generic
    DEFAULT_PORT = 873
  end
  @@schemes['RSYNC'] = RSYNC
end
#=> URI::RSYNC

URI.scheme_list
#=> {"FILE"=>URI::File, "FTP"=>URI::FTP, "HTTP"=>URI::HTTP,
#    "HTTPS"=>URI::HTTPS, "LDAP"=>URI::LDAP, "LDAPS"=>URI::LDAPS,
#    "MAILTO"=>URI::MailTo, "RSYNC"=>URI::RSYNC}

uri = URI("rsync://rsync.foo.com")
#=> #<URI::RSYNC rsync://rsync.foo.com>
