我无法在json返回的主目录中打印值。
我想循环返回以下字段
require 'httparty'
require 'rubygems'
response = HTTParty.get("https://www.instagram.com/p/BvNWyEpDoz2/?__a=1")
response['graphql']['shortcode_media'].each do |child|
puts child['__typename']
puts child['id']
puts child['display_url']
puts child['edge_media_to_parent_comment']['edges']
puts child['node']['text']
end
