My Question or Issue

I’m trying to use the API in order to call Spotify from a Ruby on Rails application. 
For that I’m using the gem rspotify. 

Everything works fine except one function was not implemented : queue function. 
So I developped it myself. 
here is the piece of code I added : 

def queue(device_id = nil, uri)  url = "me/player/queue?uri=#{uri}"  url = device_id.nil? ? url : "#{url}?device_id=#{device_id}"

  User.oauth_put(@user.id, url, {})
end

Note that this is exactly similar to the play function of rspotify which allows to directly play a song and which works.

here is the full code with other working functions : 

https://github.com/guilhermesad/rspotify/blob/master/lib/rspotify/player.rb

When trying to call that, I get the following error: 

503 Service Unavailable

here is an example showing the play function working and this one returning the error. 

> me = RSpotify::User.new(hash)
> player = RSpotify::Player.new(me)
> track = RSpotify::Track.search('Know')[0]
>
> player.play_track(track.uri)
 => nil
> player.queue(track.uri)warning: Overriding "Content-Type" header "application/json" with "application/x-www-form-urlencoded" due to payloadTraceback (most recent call last):
        1: from (irb):82
RestClient::ServiceUnavailable (503 Service Unavailable)

Could anyone help me on this?

Problem is solved.

The issue was coming from the fact that a PUT method was used instead of a POST.
Here is the fixed code:

def queue(device_id = nil, uri)
  url = "me/player/queue?uri=#{uri}"
  url = device_id.nil? ? url : "#{url}&device_id=#{device_id}"
  User.oauth_post(@user.id, url, {})
end

Hope it will save some time to others
