Introducing uri-query_params

2010-09-02 — query_params, ruby, uri

uri-query_params is a new library which allows accessing the individual parameters in the query string of a HTTP URI in Ruby. The library monkey-patches the URI::HTTP class to provide similar behavior to PHPs famous $_GET hash.

$ gem install uri-query_params

Using uri-query_params you can, inspect the URI query_params:

require 'uri/query_params'

url = URI('http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=1HY&q=bob+ross&btnG=Search')

url.query_params
# => {"btnG"=>"Search", "hs"=>"1HY", "rls"=>"org.mozilla:en-US:official", "client"=>"firefox-a", "hl"=>"en", "q"=>"bob+ross"}

url.query_params['q']
# => "bob+ross"

Also, set the URI query_params:

url.query_params['q'] = 'Upright Citizens Brigade'
url.to_s
# => "http://www.google.com/search?btnG=Search&hs=1HY&rls=org.mozilla:en-US:official&client=firefox-a&hl=en&q=Upright%20Citizens%20Brigade"

Originally, the URI::QueryParams mixin was developed for Ronin and GScraper. I decided to split the code out into a common library, to prevent conflicts between the two separate versions.

Enjoy.
