[Ruby] Read JSON from url and parse JSON

We can use the open-uri to get the content from the url. And use the JSON to parse the JSON string to hash or array.

require 'open-uri'
require 'JSON'

url = "https://api.com/result.json"
json = open(url).read
objs = JSON.parse(json) 
objs.each do |obj|
  title = obj["title"]
end

If the result is not a array. The result will be a dictionary. Just use like this:

obj = JSON.parse(json) 
title = obj["title"]
