Cinderhaze / Parsing JSON with Ruby?
Created May 7, 2015 02:51
Trying to parse AWS JSON with ruby
I found a good example of how to parse JSON with ruby on stack overflow here => http://stackoverflow.com/a/13625633
For an example of AWS JSON, I found an example at (http://unix.stackexchange.com/questions/121718/how-to-parse-json-with-shell-scripting-in-linux), but I fixed some errors in the json and have a copy here (https://gist.github.com/Cinderhaze/f122232d15eb700449f0)
I put the above json in a file (ec2s.json) and ran 'gem install json'
I have tried the following in IRB
require 'json'
file = File.open('ec2s.json')
contents = file.read
file.close

My first 'successful' attempt at getting the info I need
# JSON Parsing example
require "rubygems"
require "json"
string = '{"desc":{"someKey":"someValue","anotherKey":"value"},"main_item":{"stats":{"a":8,"b":12,"c":10}}}'
parsed = JSON.parse(string) # returns a hash
p parsed["desc"]["someKey"]
p parsed["main_item"]["stats"]["a"]
