Extracting values from a hash

Question

Hello Im using HTTParty to call for a remote json file that I need to extract the URL\'s to use in one of my tests.. the json format goes something like:

  \"man         


        

Answer 1

Try the following:

#!/usr/bin/env ruby

require 'httparty'

(HOST, ID, VERSION) = ARGV

class MyApi
  include HTTParty
  format :json
end

response = MyApi.get("http://#{HOST}/v1/dc/manifest/#{ID}/#{VERSION}")

puts response.inspect

The addition of the format :json tells HTTParty to parse the response as JSON. Then you'll get a hash you can iterate over properly.

Answer 2

Try:

file['manifest']['files'].each do |item|
   puts item['url']
end
