The module is a non-blocking wrapper around Net::LastFM::Submission module, it is truelly asynchronously. Net::LastFM::Submission contains methods for generate requests and parse response (version >= 0.5). See documentation Net::LastFM::Submission.

POE::Component::Net::LastFM::Submission start own POE::Component::Client::HTTP when the user didn't supply the parameter Client. It lets other sessions run while HTTP transactions are being processed, and it lets several HTTP transactions be processed in parallel.

    POE::Component::Net::LastFM::Submission->spawn(
        Alias  => 'LASTFM_SUBMIT',
        LastFM => {
            user     => 'net_lastfm',
            password => '12',
        },
    );

    # or

    POE::Component::Client::HTTP->spawn(
       Alias => 'HTTP_CLIENT',
       ...
    );

    POE::Component::Net::LastFM::Submission->spawn(
       Alias  => 'LASTFM_SUBMIT',
       Client => 'HTTP_CLIENT', # alias or session id of PoCo::Client::HTTP
       LastFM => {
           user     => 'net_lastfm',
           password => '12',
       },
    );

PoCo::Net::LastFM::Submission's spawn method takes a few named parameters:

* Alias

Alias sets the name by which the session will be known. If no alias is given, the component defaults is LASTFM_SUBMISSION. The alias lets several sessions interact with HTTP components without keeping (or even knowing) hard references to them. It's possible to spawn several Submission components with different names.

This is a constructor for Net::LastFM::Submission object. It takes list of parameters or hashref parameter.

* LastFM

The data for Net::LastFM::Submission constructor. It's hashref of data. Required. See Net::LastFM::Submission.

* Client

The alias or session id of an existing PoCo::Client::HTTP. Optional. See POE::Component::Client::HTTP.

* Agent

The user agent of the client. Optional. It is a agent of own PoCo::Client::HTTP. See POE::Component::Client::HTTP.

* Timeout

The timeout of the client. Optional. It is a timeout of own PoCo::Client::HTTP. See POE::Component::Client::HTTP.

Sessions communicate asynchronously with PoCo::Net::LastFM::Submission. They post requests to it, and it posts responses back.

Events have syntax like PoCo::Client::HTTP.

First param is a alias of submission session.

Second param is accepted event such as handshake, now_playing and submit.

Third param is a event for return after execute request.

Forth param is hashref param for the accepted event (for real method of Net::LastFM::Submission).

Fiveth param is a tag to identify the request.

    $_[KERNEL]->post('LASTFM_SUBMIT' => 'handshake' => 'np');

     $_[KERNEL]->post(
        'LASTFM_SUBMIT' => 'now_playing' => 'np',
        {'artist' => 'ArtistName', 'title'  => 'TrackTitle'}, # params of now_playing
        'job_id'
    );

See params of now_playing in Net::LastFM::Submission.

    $_[KERNEL]->post(
        'LASTFM_SUBMIT' => 'submit' => 'sb',
        {'artist' => 'ArtistName', 'title'  => 'TrackTitle', 'time'   => time - 10*60}, # params of submit
        'job_id'
    );

See params of submit in Net::LastFM::Submission.

The module supports trace mode - trace POE session.

    BEGIN { $ENV{SUBMISSION_TRACE}++ };
    use POE::Component::Net::LastFM::Submission;
