NAME POE::Component::CPANIDX - A POE mechanism for querying the CPANIDX VERSION version 0.12 SYNOPSIS use strict; use warnings; use POE qw(Component::CPANIDX); my $url = shift or die; my $cmd = shift or die; my $search = shift; my $idx = POE::Component::CPANIDX->spawn(); POE::Session->create( package_states => [ main => [qw(_start _reply)], ], args => [ $url, $cmd, $search ], ); $poe_kernel->run(); exit 0; sub _start { my ($URL,$CMD,$SRCH) = @_[ARG0..ARG2]; $idx->query_idx( event => '_reply', url => $URL, cmd => $CMD, search => $SRCH, ); return; } sub _reply { my $resp = $_[ARG0]; use Data::Dumper; $Data::Dumper::Indent=1; unless ( $resp->{error} ) { print Dumper( $resp->{data} ); } else { print Dumper( $resp->{error} ); } $idx->shutdown; return; } DESCRIPTION POE::Component::CPANIDX is a POE component for querying web servers that are running App::CPANIDX. CONSTRUCTOR spawn Creates a new POE::Component::CPANIDX session. Takes one optional argument alias so you can set an alias on the component to send it events later. Returns an object reference which the following methods can be used on. METHODS session_id Takes no arguments. Returns the POE::Session ID of the component. shutdown Takes no arguments. Terminates the component. query_idx event The name of the event that should be sent to the requesting session with the reply from the CPANIDX server. This is required. url The base url of the website that is running App::CPANIDX. This is required. cmd The query command to send to the server. This can be mod, dist, dists, corelist, auth, timestamp mirrors or topten. If no cmd is specified the component will default to timestamp. The first three commands require a search term. search The search term to use for the mod, dist, dists, auth, corelist commands. See OUTPUT EVENTS below for what will be sent to your session in reply. You may also set arbitary keys to pass arbitary data along with your request. These must be prefixed with an underscore _. INPUT EVENTS These are POE events that the component will accept. shutdown Takes no arguments. Terminates the component. query_idx event The name of the event that should be sent to the requesting session with the reply from the CPANIDX server. This is required. url The base url of the website that is running App::CPANIDX. This is required. cmd The query command to send to the server. This can be mod, dists, auth, timestamp or topten. If no cmd is specified the component will default to timestamp. The first three commands require a search term. search The search term to use for the mod, dists, auth commands. See OUTPUT EVENTS below for what will be sent to your session in reply. You may also set arbitary keys to pass arbitary data along with your request. These must be prefixed with an underscore _. OUTPUT EVENTS The component will send an event in response to query_idx. ARG0 of the event will be a HASHREF containing the key/values of the original request ( including any arbitary key/values passed ). It will also contain either a data key or an error key. data This will an arrayref of the data returned by the CPANIDX site. If there was no data to return then this will be a 'blank' arrayref. error If there was an error of some sort then data will not be defined and this will contain a message indicating what the problem was.
