rails best way to extract values from response hash - ruby-on-rails

Question

I'm having problems extracting values in a response hash from a call to google image search API.
I only want the value from the url key from each result.
I figured i'd call deep_symbolize_keys on the response and do something like hash.results.url , which doesn't work. I feel like i'm doing something stupid, so any pointers are welcome.
CONTROLLER CODE
_url = 'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=fuzzy%20monkey'
_response = Net::HTTP.get_response(URI.parse(_url))
#response_hash = JSON.parse _response.body
RESPONSE HASH BEFORE KEYED STORED IN #response_hash

Answer 1

are you looking for something like this?
urls = _response["responseData"]["results"].map { |result| result["url"] }
