Spotify

GoDoc Build status Build Status

This is a Go wrapper for working with Spotify's Web API.

It aims to support every task listed in the Web API Endpoint Reference, located here.

By using this library you agree to Spotify's Developer Terms of Use.

Installation

To install the library, simply

go get github.com/zmb3/spotify

Authentication

Spotify uses OAuth2 for authentication and authorization.
As of May 29, 2017 all Web API endpoints require an access token.

You can authenticate using a client credentials flow, but this does not provide any authorization to access a user's private data. For most use cases, you'll want to use the authorization code flow. This package includes an Authenticator type to handle the details for you.

Start by registering your application at the following page:

https://developer.spotify.com/my-applications/.

You'll get a client ID and secret key for your application. An easy way to provide this data to your application is to set the SPOTIFY_ID and SPOTIFY_SECRET environment variables. If you choose not to use environment variables, you can provide this data manually.

// the redirect URL must be an exact match of a URL you've registered for your application
// scopes determine which permissions the user is prompted to authorize
auth := spotify.NewAuthenticator(redirectURL, spotify.ScopeUserReadPrivate)

// if you didn't store your ID and secret key in the specified environment variables,
// you can set them manually here
auth.SetAuthInfo(clientID, secretKey)

// get the user to this URL - how you do that is up to you
// you should specify a unique state string to identify the session
url := auth.AuthURL(state)

// the user will eventually be redirected back to your redirect URL
// typically you'll have a handler set up like the following:
func redirectHandler(w http.ResponseWriter, r *http.Request) {
      // use the same state string here that you used to generate the URL
      token, err := auth.Token(state, r)
      if err != nil {
            http.Error(w, "Couldn't get token", http.StatusNotFound)
            return
      }
      // create a client using the specified token
      client := auth.NewClient(token)

      // the client can now be used to make authenticated requests
}

Helpful Hints

Optional Parameters

Many of the functions in this package come in two forms - a simple version that omits optional parameters and uses reasonable defaults, and a more sophisticated version that accepts additional parameters. The latter is suffixed with Opt to indicate that it accepts some optional parameters.

Automatic Retries

The API will throttle your requests if you are sending them too rapidly. The client can be configured to wait and re-attempt the request. To enable this, set the AutoRetry field on the Client struct to true.

For more information, see Spotify rate-limits.

API Examples

Examples of the API can be found in the examples directory.

You may find tools such as Spotify's Web API Console or Rapid API valuable for experimenting with the API.

AudioFeatures contains various high-level acoustic attributes for a particular track.

type Authenticator 

type Authenticator struct {
	// contains filtered or unexported fields
}

Authenticator provides convenience functions for implementing the OAuth2 flow. You should always use `NewAuthenticator` to make them.

Example: 

a := spotify.NewAuthenticator(redirectURL, spotify.ScopeUserLibaryRead, spotify.ScopeUserFollowRead)
// direct user to Spotify to log in
http.Redirect(w, r, a.AuthURL("state-string"), http.StatusFound)

// then, in redirect handler:
token, err := a.Token(state, r)
client := a.NewClient(token)

func NewAuthenticator 

func NewAuthenticator(redirectURL string, scopes ...string) Authenticator

NewAuthenticator creates an authenticator which is used to implement the OAuth2 authorization flow. The redirectURL must exactly match one of the URLs specified in your Spotify developer account.

By default, NewAuthenticator pulls your client ID and secret key from the SPOTIFY_ID and SPOTIFY_SECRET environment variables. If you'd like to provide them from some other source, you can call `SetAuthInfo(id, key)` on the returned authenticator.

func (Authenticator) AuthURL 

func (a Authenticator) AuthURL(state string) string

AuthURL returns a URL to the the Spotify Accounts Service's OAuth2 endpoint.

State is a token to protect the user from CSRF attacks. You should pass the same state to `Token`, where it will be validated. For more info, refer to http://tools.ietf.org/html/rfc6749#section-10.12.

func (Authenticator) AuthURLWithDialog 

func (a Authenticator) AuthURLWithDialog(state string) string

AuthURLWithDialog returns the same URL as AuthURL, but sets show_dialog to true

func (Authenticator) AuthURLWithOpts 

func (a Authenticator) AuthURLWithOpts(state string, opts ...oauth2.AuthCodeOption) string

AuthURLWithOpts returns the bause AuthURL along with any extra URL Auth params

func (Authenticator) Exchange 

func (a Authenticator) Exchange(code string) (*oauth2.Token, error)

Exchange is like Token, except it allows you to manually specify the access code instead of pulling it out of an HTTP request.

func (Authenticator) NewClient 

func (a Authenticator) NewClient(token *oauth2.Token) Client

NewClient creates a Client that will use the specified access token for its API requests.

func (*Authenticator) SetAuthInfo 

func (a *Authenticator) SetAuthInfo(clientID, secretKey string)

SetAuthInfo overwrites the client ID and secret key used by the authenticator. You can use this if you don't want to store this information in environment variables.

func (Authenticator) Token 

func (a Authenticator) Token(state string, r *http.Request) (*oauth2.Token, error)

Token pulls an authorization code from an HTTP request and attempts to exchange it for an access token. The standard use case is to call Token from the handler that handles requests to your application's redirect URL.

func (Authenticator) TokenWithOpts 

func (a Authenticator) TokenWithOpts(state string, r *http.Request, opts ...oauth2.AuthCodeOption) (*oauth2.Token, error)

TokenWithOpts performs the same function as the Authenticator Token function but takes in optional URL Auth params

type Category 

type Category struct {
	// A link to the Web API endpoint returning full details of the category
	Endpoint string `json:"href"`
	// The category icon, in various sizes
	Icons []Image `json:"icons"`
	// The Spotify category ID.  This isn't a base-62 Spotify ID, its just
	// a short string that describes and identifies the category (ie "party").
	ID string `json:"id"`
	// The name of the category
	Name string `json:"name"`
}

Category is used by Spotify to tag items in. For example, on the Spotify player's "Browse" tab.

type CategoryPage 

type CategoryPage struct {
	Categories []Category `json:"items"`
	// contains filtered or unexported fields
}

CategoryPage contains Category objects returned by the Web API.

type Client 

type Client struct {
	AutoRetry      bool
	AcceptLanguage string
	// contains filtered or unexported fields
}

Client is a client for working with the Spotify Web API. It is created by `NewClient` and `Authenticator.NewClient`.

func NewClient 

func NewClient(client *http.Client) Client

NewClient returns a client for working with the Spotify Web API. The provided HTTP client must include the user's access token in each request; if you do not have such a client, use the `Authenticator.NewClient` method instead.

func (*Client) AddTracksToLibrary 

func (c *Client) AddTracksToLibrary(ids ...ID) error

AddTracksToLibrary saves one or more tracks to the current user's "Your Music" library. This call requires the ScopeUserLibraryModify scope. A track can only be saved once; duplicate IDs are ignored.

func (*Client) AddTracksToPlaylist 

func (c *Client) AddTracksToPlaylist(playlistID ID, trackIDs ...ID) (snapshotID string, err error)

AddTracksToPlaylist adds one or more tracks to a user's playlist. This call requires ScopePlaylistModifyPublic or ScopePlaylistModifyPrivate. A maximum of 100 tracks can be added per call.

The current user must own the playlist in order to modify it.

func (*Client) ChangePlaylistName 

func (c *Client) ChangePlaylistName(playlistID ID, newName string) error

ChangePlaylistName changes the name of a playlist. This call requires that the user has authorized the ScopePlaylistModifyPublic or ScopePlaylistModifyPrivate scopes (depending on whether the playlist is public or private). The current user must own the playlist in order to modify it.

func (*Client) ChangePlaylistNameAccessAndDescription 

func (c *Client) ChangePlaylistNameAccessAndDescription(playlistID ID, newName, newDescription string, public bool) error

ChangePlaylistNameAccessAndDescription combines ChangePlaylistName, ChangePlaylistAccess, and ChangePlaylistDescription into a single Web API call. It requires that the user has authorized the ScopePlaylistModifyPublic or ScopePlaylistModifyPrivate scopes (depending on whether the playlist is currently public or private). The current user must own the playlist in order to modify it.

func (*Client) ChangePlaylistNameAndAccess 

func (c *Client) ChangePlaylistNameAndAccess(playlistID ID, newName string, public bool) error

ChangePlaylistNameAndAccess combines ChangePlaylistName and ChangePlaylistAccess into a single Web API call.

The current user must own the playlist in order to modify it.

func (*Client) CreatePlaylistForUser 

func (c *Client) CreatePlaylistForUser(userID, playlistName, description string, public bool) (*FullPlaylist, error)

CreatePlaylistForUser creates a playlist for a Spotify user. The playlist will be empty until you add tracks to it. The playlistName does not need to be unique - a user can have several playlists with the same name.

Creating a public playlist for a user requires ScopePlaylistModifyPublic; creating a private playlist requires ScopePlaylistModifyPrivate.

On success, the newly created playlist is returned.

func (*Client) CurrentUser 

func (c *Client) CurrentUser() (*PrivateUser, error)

CurrentUser gets detailed profile information about the current user.

Reading the user's email address requires that the application has the ScopeUserReadEmail scope. Reading the country, display name, profile images, and product subscription level requires that the application has the ScopeUserReadPrivate scope.

Warning: The email address in the response will be the address that was entered when the user created their spotify account. This email address is unverified - do not assume that Spotify has checked that the email address actually belongs to the user.

func (*Client) CurrentUserFollows 

func (c *Client) CurrentUserFollows(t string, ids ...ID) ([]bool, error)

CurrentUserFollows checks to see if the current user is following one or more artists or other Spotify Users. This call requires ScopeUserFollowRead.

The t argument indicates the type of the IDs, and must be either "user" or "artist".

The result is returned as a slice of bool values in the same order in which the IDs were specified.

func (*Client) CurrentUsersAlbums 

func (c *Client) CurrentUsersAlbums() (*SavedAlbumPage, error)

CurrentUsersAlbums gets a list of albums saved in the current Spotify user's "Your Music" library.

func (*Client) CurrentUsersAlbumsOpt

CurrentUsersFollowedArtistsOpt is like CurrentUsersFollowedArtists, but it accept the optional arguments limit and after. Limit is the maximum number of items to return (1 <= limit <= 50), and after is the last artist ID retrieved from the previous request. If you don't wish to specify either of the parameters, use -1 for limit and the empty string for after.

func (*Client) CurrentUsersPlaylists 

func (c *Client) CurrentUsersPlaylists() (*SimplePlaylistPage, error)

CurrentUsersPlaylists gets a list of the playlists owned or followed by the current spotify user.

Private playlists require the ScopePlaylistReadPrivate scope. Note that this scope alone will not return collaborative playlists, even though they are always private. In order to retrieve collaborative playlists the user must authorize the ScopePlaylistReadCollaborative scope.

Matching of search keywords is NOT case sensitive. Keywords are matched in any order unless surrounded by double quotes. Searching for playlists will return results where the query keyword(s) match any part of the playlist's name or description. Only popular public playlists are returned.

The operator NOT can be used to exclude results. For example, query = "roadhouse NOT blues" returns items that match "roadhouse" but excludes those that also contain the keyword "blues". Similarly, the OR operator can be used to broaden the search. query = "roadhouse OR blues" returns all results that include either of the terms. Only one OR operator can be used in a query.

Operators should be specified in uppercase.

The asterisk (*) character can, with some limitations, be used as a wildcard (maximum of 2 per query). It will match a variable number of non-white-space characters. It cannot be used in a quoted phrase, in a field filter, or as the first character of a keyword string.

By default, results are returned when a match is found in any field of the target object type. Searches can be made more specific by specifying an album, artist, or track field filter. For example, "album:gold artist:abba type:album" will only return results with the text "gold" in the album name and the text "abba" in the artist's name.

The field filter "year" can be used with album, artist, and track searches to limit the results to a particular year. For example "bob year:2014" or "bob year:1980-2020".

The field filter "tag:new" can be used in album searches to retrieve only albums released in the last two weeks. The field filter "tag:hipster" can be used in album searches to retrieve only albums with the lowest 10% popularity.

Other possible field filters, depending on object types being searched, include "genre", "upc", and "isrc". For example "damian genre:reggae-pop".

func (*Client) SearchOpt 

func (c *Client) SearchOpt(query string, t SearchType, opt *Options) (*SearchResult, error)

type SimpleTrackPage 

type SimpleTrackPage struct {
	Tracks []SimpleTrack `json:"items"`
	// contains filtered or unexported fields
}

SimpleTrackPage contains SimpleTracks returned by the Web API.

type TrackAttributes 

type TrackAttributes struct {
	// contains filtered or unexported fields
}

TrackAttributes contains various tuneable parameters that can be used for recommendations. For each of the tuneable track attributes, target, min and max values may be provided. Target: 

Tracks with the attribute values nearest to the target values will be preferred.
For example, you might request TargetEnergy=0.6 and TargetDanceability=0.8.
All target values will be weighed equally in ranking results.

Max: 

A hard ceiling on the selected track attribute’s value can be provided.
For example, MaxInstrumentalness=0.35 would filter out most tracks
that are likely to be instrumental.

Min: 

A hard floor on the selected track attribute’s value can be provided.
For example, min_tempo=140 would restrict results to only those tracks
with a tempo of greater than 140 beats per minute.
