DESCRIPTION
PubSubHubbub subscriber implementation in the form of a Plack app and a
client. Originally developed for storyfindr.com <http://storyfindr.com>
$self->config( $conf )
Get/Set the Plack::App::PubSubHubbub::Subscriber::Config object. This
same config object can be use to instanciate the client
Plack::App::PubSubHubbub::Subscriber::Client
$self->on_ping( sub { my ($content_type, $content, $token) = @_ } )
Triggered when a new ping is received, the parameters are the content
type, the raw content, and the token in that order. Note that the token
is available only if the configuration flag "token_in_path" is set (the
default). Also note that, in any case, the token is undef if you didn't
use a token to (un)subcribe. The return value is ignore.
$self->on_verify( sub { my ($topic, $token, $mode, $lease) = @_ } )
Triggered when a subscribe/unsubscribe request is received, the
parameters are the topic, the token, the mode, and the number of seconds
of the lease, in that order. Note that the token is undef if you didn't
use a token to (un)subcribe. Given these parameters, this coderef must
return 1 for verified, or 0 for rejected.
$self->callback_path
Return the path part of the callback URL. Useful for doing "mount
$app->callback_path, $app;"
LIMITATION
the "Authenticated Content Distribution" is not supported.
