SoundCloud API Wrapper

Description

The official SoundCloud API wrapper. It provides simple methods to handle authorization and to execute HTTP calls.

Installation

gem install soundcloud

Examples

Print links of the 10 hottest tracks

# register a client with YOUR_CLIENT_ID as client_id_
client = SoundCloud.new(:client_id => YOUR_CLIENT_ID)
# get 10 hottest tracks
tracks = client.get('/tracks', :limit => 10, :order => 'hotness')
# print each link
tracks.each do |track|
  puts track.permalink_url
end

OAuth2 user credentials flow and print the username of the authenticated user

# register a new client, which will exchange the username, password for an access_token
# NOTE: the SoundCloud API Docs advise not to use the user credentials flow in a web app.
# In any case, never store the password of a user.
client = SoundCloud.new({
  :client_id     => YOUR_CLIENT_ID,
  :client_secret => YOUR_CLIENT_SECRET,
  :username      => 'some@email.com',
  :password      => 'userpass'
})

# print logged in username
puts client.get('/me').username

OAuth2 authorization code flow

client = SoundCloud.new({
  :client_id     => YOUR_CLIENT_ID,
  :client_secret => YOUR_CLIENT_SECRET,
  :redirect_uri  => YOUR_REDIRECT_URI,
})

redirect client.authorize_url()
# the user should be redirected to "https://soundcloud.com/connect?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=YOUR_REDIRECT_URI"
# after granting access he will be redirected back to YOUR_REDIRECT_URI
# in your respective handler you can build an exchange token from the transmitted code
client.exchange_token(:code => params[:code])

OAuth2 refresh token flow, upload a track and print its link

# register a new client which will exchange an existing refresh_token for an access_token
client = SoundCloud.new({
  :client_id     => YOUR_CLIENT_ID,
  :client_secret => YOUR_CLIENT_SECRET,
  :refresh_token => SOME_REFRESH_TOKEN
})

# upload a new track with audio.mp3 as audio and image.jpg as artwork
track = client.post('/tracks', :track => {
  :title      => 'a new track',
  :asset_data => File.new('audio.mp3')
})

# print new tracks link
puts track.permalink_url

Resolve a track url and print its id

# register the client
client = SoundCloud.new(:client_id => YOUR_CLIENT_ID)

# call the resolve endpoint with a track url
track = client.get('/resolve', :url => "http://soundcloud.com/forss/flickermood")

# print the track id
puts track.id

Initializing a client with an access token and updating the users profile description

# initializing a client with an access token
client = SoundCloud.new(:access_token => SOME_ACCESS_TOKEN)

# updating the users profile description
client.put("/me", :user => {:description => "a new description"})

Add a track to a playlist / set

client = SoundCloud.new(:access_token => "A_VALID_TOKEN")

# get my last playlist
playlist = client.get("/me/playlists").first

# get ids of contained tracks
track_ids = playlist.tracks.map(&:id) # => [22448500, 21928809]

# adding a new track 21778201
track_ids << 21778201 # => [22448500, 21928809, 21778201]

# map array of ids to array of track objects:
tracks = track_ids.map{|id| {:id => id}} # => [{:id=>22448500}, {:id=>21928809}, {:id=>21778201}]

# send update/put request to playlist
playlist = client.put(playlist.uri, :playlist => {
  :tracks => tracks
})

# print the list of track ids of the updated playlist:
p playlist.tracks.map(&:id)

Interface

SoundCloud.new(options={})

Stores the passed options and call exchange_token in case options are passed that allow an exchange of tokens.

SoundCloud#exchange_token(options={})

Stores the passed options and try to exchange tokens if no access_token is present and:

• refresh_token, client_id and client_secret is present.
• client_id, client_secret, username, and password is present
• client_id, client_secret, redirect_uri, and code is present

SoundCloud#authorize_url(options={})

Stores the passed options except for state and display and return an authorize url. The client_id and redirect_uri options need to present to generate the authorize url. The state and display options can be used to set the parameters accordingly in the authorize url.

SoundCloud#get, SoundCloud#post, SoundCloud#put, SoundCloud#delete, SoundCloud#head

These methods expose all available HTTP methods. They all share the signature (path_or_uri, query={}, options={}). The query hash will be merged with the options hash and passed to httparty. Depending on if the client is authorized it will either add the client_id or the access_token as a query parameter. In case an access_token is expired and a refresh_token, client_id and client_secret is present it will try to refresh the access_token and retry the call. The response is either a Hashie::Mash or an array of Hashie::Mashes. The mashes expose all resource attributes as methods and the original response through HashResponseWrapper#response.

SoundCloud#client_id, client_secret, access_token, refresh_token, use_ssl?

These methods are accessors for the stored options.

SoundCloud#on_exchange_token

A Proc passed to on_exchange_token will be called each time a token was successfully exchanged or refreshed

SoundCloud#expires_at

Returns a date based on the expires_in attribute returned from a token exchange.

SoundCloud#expired?

Will return true or false depending on if expires_at is in the past.

Error Handling

In case a request was not successful a SoundCloud::ResponseError will be raised. The original HTTParty response is available through SoundCloud::ResponseError#response.
