Accessing JSON objects in Ruby -


i have json file looks kind of this:

{   "results": [     {       "lookup": null,       "result": {         "paths": [           {             "domain": "value1.ltd",             "url": "",             "text1": "",             "modules": [               {                 "name": "value",                 "tag": "value",                 "firstdetected": "1111111111",                 "lastdetected": "11111111111"               },               {                 "name": "value",                 "tag": "value",                 "firstdetected": "111111111111",                 "lastdetected": "11111111111111"               }             ]           }         ]       }     }   ] }

how print domain , access module.names in ruby , print module.names console:

#!/usr/bin/ruby require 'rubygems' require 'json' require 'pp'  json = file.read('input.json')

and 1 know of resources ruby , json new it?

json.parse takes json string , return hash can manipulated other hash.

#!/usr/bin/ruby require 'rubygems' require 'json' require 'pp'  # symbolize keys makes hash easier work data = json.parse(file.read('input.json'), symbolize_keys: true)  # loop through :results if there data[:results].each |r|   # loop through [:result][:paths] if there   r[:result][:paths].each |path|     # path refers current item     path[:modules].each |module|       # module refers current item       puts module[:name]     end if path[:modules].any?   end if r[:result][:paths].any? end if data[:results].any?
