NAME

POE::Component::WWW::Pastebin::Many::Retrieve - non-blocking wrapper around WWW::Pastebin::Many::Retrieve

SYNOPSIS


            

              
              
use strict;
use warnings;
use POE qw(Component::WWW::Pastebin::Many::Retrieve);
my $poco = POE::Component::WWW::Pastebin::Many::Retrieve->spawn;
POE::Session->create(
    package_states => [ main => [qw(_start retrieved)] ],
);
$poe_kernel->run;
sub _start {
    $poco->retrieve( {
            uri     => 'http://phpfi.com/302683',
            event   => 'retrieved',
            _random => scalar localtime,
        }
    );
}
sub retrieved {
    my $in_ref = $_[ARG0];
    print "This is request from $in_ref->{_random}\n";
    if ( $in_ref->{error} ) {
        print "Got error: $in_ref->{error}\n";
    }
    else {
        print "Paste $in_ref->{uri} contains:\n$in_ref->{content}\n";
    }
    $poco->shutdown;
}

Using event based interface is also possible.

DESCRIPTION

The module is a non-blocking wrapper around WWW::Pastebin::Many::Retrieve which provides interface to retrieve pastes from many different pastebin sites.

CONSTRUCTOR

spawn


            

              
              
my $poco = POE::Component::WWW::Pastebin::Many::Retrieve->spawn;
POE::Component::WWW::Pastebin::Many::Retrieve->spawn(
    alias => 'paster',
    timeout => 30,
    options => {
        debug => 1,
        trace => 1,
        # POE::Session arguments for the component
    },
    debug => 1, # output some debug info
);

The spawn method returns a POE::Component::WWW::Pastebin::Many::Retrieve object. It takes a few arguments, all of which are optional. The possible arguments are as follows:

alias


            

              
              
->spawn( alias => 'paster' );

Optional. Specifies a POE Kernel alias for the component.

timeout


            

              
              
->spawn( timeout => 30 );

Optional. Specifies the network timeout to relate to when retrieving pastes. Defaults to: 30 seconds

options


            

              
              
->spawn(
    options => {
        trace => 1,
        default => 1,
    },
);

Optional. A hashref of POE Session options to pass to the component's session.

debug


            

              
              
->spawn(
    debug => 1
);

When set to a true value turns on output of debug messages. Defaults to: 0.

METHODS

retrieve


            

              
              
$poco->retrieve( {
        event       => 'event_for_output',
        uri         => 'http://uri_to_paste_you_want_to_retrieve.com',
        _blah       => 'pooh!',
        session     => 'other',
    }
);

Takes a hashref as an argument, does not return a sensible return value. See retrieve event's description for more information.

session_id


            

              
              
my $poco_id = $poco->session_id;

Takes no arguments. Returns component's session ID.

shutdown


            

              
              
$poco->shutdown;

Takes no arguments. Shuts down the component.

ACCEPTED EVENTS

retrieve


            

              
              
$poe_kernel->post( paster => retrieve => {
        event       => 'event_for_output',
        uri         => 'http://uri_to_paste_you_want_to_retrieve.com',
        _blah       => 'pooh!',
        session     => 'other',
    }
);

Instructs the component to retrieve a paste. Takes a hashref as an argument, the possible keys/value of that hashref are as follows:

event


            

              
              
{ event => 'results_event', }

Mandatory. Specifies the name of the event to emit when results are ready. See OUTPUT section for more information.

uri


            

              
              
{ uri => 'http://uri_to_paste_you_want_to_retrieve.com' }

Mandatory. Takes a scalar containing a URI poiting to the paste you would like to retrieve. See "SUPPORTED PASTEBINS" section in documentation for WWW::Pastebin::Many::Retrieve module regarding accepted pastebins.

session


            

              
              
{ session => 'other' }
{ session => $other_session_reference }
{ session => $other_session_ID }

Optional. Takes either an alias, reference or an ID of an alternative session to send output to.

user defined


            

              
              
{
    _user    => 'random',
    _another => 'more',
}

Optional. Any keys starting with _ (underscore) will not affect the component and will be passed back in the result intact.

shutdown


            

              
              
$poe_kernel->post( paster => 'shutdown' );

Takes no arguments. Tells the component to shut itself down.

OUTPUT


            

              
              
$VAR1 = {
    'response' => {
        'hits' => '0',
        'lang' => 'plaintext',
        'name' => 'N/A',
        'content' => 'paste content here',
        'age' => '14.03.08 21:59'
    },
    'content' => 'paste content here',
    'uri' => 'http://phpfi.com/302683',
    '_random' => 'Sun Mar 30 07:33:00 2008'
};

The event handler set up to handle the event which you've specified in the event argument to retrieve() method/event will recieve input in the $_[ARG0] in a form of a hashref. The possible keys/value of that hashref are as follows:

content


            

              
              
{ 'content' => 'paste content here', }

Unless an error occured the content key will be present and its value will be the actual content of the paste you retrieved.

response


            

              
              
{
    'response' => {
        'hits' => '0',
        'lang' => 'plaintext',
        'name' => 'N/A',
        'content' => 'paste content here',
        'age' => '14.03.08 21:59'
    },
}

Unless an error occured the response key will contain the return value of response() method of the specific object which was used to retrieve your paste. See WWW::Pastebin::Many::Retrieve for more information.

error


            

              
              
{ 'error' => 'Nework error: 500 read timeout' }

If an error occured during retrieval of your paste the error key will be present and its value will be a human parsable error message explaining why we failed.

uri


            

              
              
{ 'uri' => 'http://phpfi.com/302683', }

The uri key will contain whatever you've specified in the uri argument to retrieve() event/method.

user defined


            

              
              
{ '_blah' => 'foos' }

Any arguments beginning with _ (underscore) passed into the retrieve() event/method will be present intact in the result.
