问题
This is a sample script. When I hit Ctrl+C, the bot quits IRC but it reconnects back after some time. How do I shut down the bot correctly?
#!/usr/bin/perl
package main;
my $bot = Perlbot->new (server => 'irc.dal.net');
$SIG{'INT'} = 'Handler';
$SIG{'TERM'} = 'Handler';
sub Handler {
print "\nShutting down bot...\n";
$bot->shutdown('Killed.');
};
$bot->run;
package Perlbot;
use base qw(Bot::BasicBot);
sub connected {
my $self = shift;
$self->join('#codetestchan');
}
回答1:
I've taken over maintainership of Bot::BasicBot, and as of version 0.82, you can shut it down properly with $bot->shutdown($quit_message)
.
回答2:
From looking at Bot::BasicBot's documentation and source code, I can't find a graceful way to shut it down. As you demonstrated, calling $bot->shutdown()
(which actually sends a shutdown
event to POE::Component::IRC
) will just cause Bot::BasicBot
to reconnect (same with $bot->quit()
by the way).
This and other limitations users have run into have caused me to recommend using POE::Component::IRC
directly. It has many plugins nowadays for features provided by Bot::BasicBot
which were missing when Bot::BasicBot
was created. While you may have to type a bit more to get a basic bot up and running, you have much more flexibility. Below is a bot like the one in your example, without using Bot::BasicBot
. It will send a quit message to the IRC server when you press CTRL+C, wait until it has been disconnected, then exit:
#!/usr/bin/env perl
use strict;
use warnings;
use POE;
use POE::Component::IRC::State;
use POE::Component::IRC::Common qw(parse_user);
use POE::Component::IRC::Plugin::Connector;
use POE::Component::IRC::Plugin::AutoJoin;
# create our session
POE::Session->create(
package_states => [
# event handlers
(__PACKAGE__) => [qw(_start int irc_join irc_disconnected)]
]
);
# start the event loop
POE::Kernel->run();
# session start handler
sub _start {
my ($kernel, $heap) = @_[KERNEL, HEAP];
# handle CTRL+C
$kernel->sig(INT => 'int');
# create bot object
my $irc = POE::Component::IRC::State->spawn(
server => 'irc.freenode.net',
nick => 'basic123bot',
debug => 1,
);
# save $irc in our session's storage heap
$heap->{irc} = $irc;
# handle reconnects
$irc->plugin_add('Connector', POE::Component::IRC::Plugin::Connector->new());
# handle channel joining
$irc->plugin_add('AutoJoin', POE::Component::IRC::Plugin::AutoJoin->new(
Channels => ['#foo123bar'],
));
# connect to IRC
$irc->yield('connect');
}
# interrupt signal handler
sub int {
my ($kernel, $heap) = @_[KERNEL, HEAP];
$heap->{irc}->yield('quit', 'Quitting, bye!');
$heap->{shutting_down} = 1;
$kernel->sig_handled();
}
# join handler
sub irc_join {
my ($who, $chan) = @_[ARG0, ARG1];
my $irc = $_[HEAP]->{irc};
my ($nick, $user, $host) = parse_user($who);
if ($nick eq $irc->nick_name()) {
# say hello to channel members
$irc->yield('privmsg', $chan, 'Hello everybody');
}
}
# disconnect handler
sub irc_disconnected {
my ($heap) = $_[HEAP];
# shut down if we disconnected voluntarily
$heap->{irc}->yield('shutdown') if $heap->{shutting_down};
}
