Question

我正在创建一个音乐播放器，根据Rcmmndr api的推荐从AWS S3中提取歌曲。该播放器是一个JavaScript播放器，但使用红宝石后端来获取歌曲。每次我进入具有播放器的页面时，我的服务器都会中止，我必须重新启动它们才能运行我的应用程序。这是我运行的ruby脚本：

songs = Database.check('songs').body #This pulls the list of songs from the database
user_id = Database.check("users/" + session[:user] + "/user_id").body #This pulls the user id

uri = URI.parse "http://api.rcmmndr.com/api_key/#{ENV['rcmmndr_api_key']}/recommend/#{user_id}"
http = Net::HTTP.new(uri.host, uri.port)
response = http.request(Net::HTTP::Get.new(uri.request_uri))

#If there are no recommendations then the player randomly selects a song from the database
if response.body.to_s != "{}"
    song = JSON.parse(response.body).to_a.sample(1)[0][0]
    artist = Database.check("songs/" + song + "/artist").body
    title = Database.check("songs/" + song + "/title").body
else
    song = songs.to_a.sample(1)[0][0]
    artist = Database.check("songs/" + song + "/artist").body
    title = Database.check("songs/" + song + "/title").body
end

#The song's information is stored into JSON that is read by the javascript 
song_to_play = {}
song_to_play[:id] = song
song_to_play[:url] = "https://s3.amazonaws.com/bucket/#{song}"
song_to_play[:artist] = artist
song_to_play[:title] = title
song_to_play.to_json

我的终端吐出大约600条看起来像这样的线条以及许多其他线条，包括宝石的位置

有人可以帮我找到原因吗？当我从我的应用程序中删除该代码时，它运行时音乐播放器不播放是唯一的问题。（如果重要的话，我正在编写Cloud 9开发环境）

在我的ruby语法中的某处但我无法找到它
