NAME POE::Component::CPANIDX - A POE mechanism for querying the CPANIDX 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.
