DESCRIPTION

Wrapper for the Spotify Web API.

https://developer.spotify.com/web-api/

Have access to a JSON viewer to help develop and debug. The Chrome JSON viewer is very good and provides the exact path of the item within the JSON in the lower left of the screen as you mouse over an element.

CONSTRUCTOR ARGS

ua

You may provide your own user agent object to the constructor. This should be a LWP:UserAgent or a subclass of it, like WWW::Mechanize. If you are using WWW::Mechanize, you may want to set autocheck off. To get extra debugging information, you can do something like this:

    use LWP::ConsoleLogger::Easy qw( debug_ua );
    use WWW::Mechanize ();
    use WWW::Spotify ();

    my $mech = WWW::Mechanize->new( autocheck => 0 );
    debug_ua( $mech );
    my $spotify = WWW::Spotify->new( ua => $mech )

METHODS

auto_json_decode

When true results will be returned as JSON instead of a perl data structure

    $spotify->auto_json_decode(1);

get

Returns a specific item or array of items from the JSON result of the last action.

    $result = $spotify->search(
                        'tania bowra' ,
                        'artist' ,
                        { limit => 15 , offset => 0 }
    );

 my $image_url = $spotify->get( 'artists.items[0].images[0].url' );

JSON::Path is the underlying library that actually parses the JSON.

query_full_url( $url , [needs o_auth] )

Results from some calls (playlist for example) return full urls that can be in their entirety. This method allows you make a call to that url and use all of the o_auth and other features provided.

    $spotify->query_full_url( "https://api.spotify.com/v1/users/spotify/playlists/06U6mm6KPtPIg9D4YGNEnu" , 1 );

album

equivalent to /v1/albums/{id}

    $spotify->album('0sNOF9WDwhWunNAHPD3Baj');

used album vs albums since it is a singular request

albums

equivalent to /v1/albums?ids={ids}

    $spotify->albums( '41MnTivkwTO3UUJ8DrqEJJ,6JWc4iAiJ9FjyK0B59ABb4,6UXCm6bOO4gFlDQZV5yL37' );

or

    $spotify->albums( [ '41MnTivkwTO3UUJ8DrqEJJ',
                        '6JWc4iAiJ9FjyK0B59ABb4',
                        '6UXCm6bOO4gFlDQZV5yL37' ] );

    {

        offset => 1

    }
    );

artist

equivalent to /v1/artists/{id}

    $spotify->artist( '0LcJLqbBmaGUft1e9Mm8HV' );

used artist vs artists since it is a singular request and avoids collision with "artists" method

artists

equivalent to /v1/artists?ids={ids}

    my $artists_multiple = '0oSGxfWSnnOXhD2fKuz2Gy,3dBVyJ7JuOMt4GE9607Qin';

    $spotify->artists( $artists_multiple );

artist_albums

                        { album_type => 'single',
                          # country => 'US',
                          limit   => 2,
                          offset  => 0
                        }  );

artist_top_tracks

equivalent to /v1/artists/{id}/top-tracks

equivalent to /v1/search?type=album (etc)

    $spotify->search(
                        'tania bowra' ,
                        'artist' ,
                        { limit => 15 , offset => 0 }

oauth_client_secret

needed for requests that require OAuth, see Spotify API documentation for more information

    $spotify->oauth_client_secret('2xfjijkcjidjkfdi');

response_status

returns the response code for the last request made

    my $status = $spotify->response_status();

response_content_type

returns the response type for the last request made, helpful to verify JSON

    my $content_type = $spotify->response_content_type();

custom_request_handler

pass a callback subroutine to this method that will be run at the end of the request prior to die_on_response_error, if enabled

    # $m is the WWW::Mechanize object
    $spotify->custom_request_handler(
        sub { my $m = shift;
            if ($m->status() == 401) {

if ($@) { warn $spotify->last_error(); }

last_error

returns last_error (if applicable) from the most recent request. reset to empty string on each request
