コピーエラーである可能性がありますが、 'ハッシュ'の '配列'のようです – whodini9

'media'アイテムが複数ある場合どうなりますか？ – whodini9

きちんと整えられていないかもしれませんが、引き続き次のことを試すことができます：

require 'json' 
test = JSON.parse(json) 
test.each {|k| 
p "============================" 
full_text = k['full_text'] unless k['full_text'].nil? 
urls = k['entities']['urls'] unless k['entities']['urls'].nil? 
urls.each {|u| 
    entities_url = u['url'] unless u['url'].nil? 
    p "Url: #{entities_url}" } 
lang = k['lang'] unless k['lang'] 
media = k['entities']['media'] 
extended_media = k['extended_entities']['media'] unless k['extended_entities'].nil? 
p "Full text: #{full_text}" unless full_text.nil? 

media.each {|u| 
p "Media url: #{u['media_url_https']}" unless u['media_url_https'].nil? 
} unless media.nil? 


extended_media.each {|u| 
p "Extended url: #{u['media_url_https']}" unless u['media_url_https'].nil? 
} unless extended_media.nil? 
p "Lang: #{lang}" unless lang.nil? 
p "=============================" 
}
