Generate URIs from Hash in Ruby

HashToURI.rb

require "net/https"

# Regular URI
URI::HTTP.build(
  :host => "domain.com"
)
# http://domain.com

# Secure URI
URI::HTTPS.build(
  :host => "domain.com"
)
# https://domain.com

# Advanced URI
URI::HTTPS.build(
  :host => "sub.domain.com",
  :path => "/path",
  :port => 8888,
  :userinfo => 'user:pass',
  :query => 'foo=bar&bar=foo'
)
# https://user:pass@sub.domain.com:8888/path?foo=bar&bar=foo

  def to_param
    self.to_a.map { |x| "#{x[0]}=#{x[1]}" }.join("&")
  end
end

URI::HTTPS.build(
  :host => "sub.domain.com",

  :port => 8888,
