我正在尝试制作一个Jabber机器人,但在等待消息时我无法保持运行状态。如何让我的脚本继续运行?我试过调用一个子程序,它有一个while循环,我理论上已经设置检查任何消息并作出相应的反应,但我的脚本不是这样的。
以下是我的来源:http://pastebin.com/03Habbvh
# set jabber bot callbacks $jabberBot->SetMessageCallBacks(chat=>\&chat); $jabberBot->SetPresenceCallBacks(available=>\&welcome,unavailable=>\&killBot); $jabberBot->SetCallBacks(receive=>\&prnt,iq=>\&gotIQ); $jabberBot->PresenceSend(type=>"available"); $jabberBot->Process(1); sub welcome { print "Welcome!\n"; $jabberBot->MessageSend(to=>$jbrBoss->GetJID(),subject=>"",body=>"Hello There!",type=>"chat",priority=>10); &keepItGoing; } sub prnt { print $_[1]."\n"; } #$jabberBot->MessageSend(to=>$jbrBoss->GetJID(),subject=>"",body=>"Hello There! Global...",type=>"chat",priority=>10); #$jabberBot->Process(5); #&keepItGoing; sub chat { my ($sessionID,$msg) = @_; $dump->pl2xml($msg); if($msg->GetType() ne 'get' && $msg->GetType() ne 'set' && $msg->GetType() ne '') { my $jbrCmd = &trimSpaces($msg->GetBody()); my $dbQry = $dbh->prepare("SELECT command,acknowledgement FROM commands WHERE message = '".lc($jbrCmd)."'"); $dbQry->execute(); if($dbQry->rows() > 0 && $jbrCmd !~ /^insert/si) { my $ref = $dbQry->fetchrow_hashref(); $dbQry->finish(); $jabberBot->MessageSend(to=>$msg->GetFrom(),subject=>"",body=>$ref->{'acknowledgement'},type=>"chat",priority=>10); eval $ref->{'command'}; &keepItGoing; } else { $jabberBot->MessageSend(to=>$msg->GetFrom(),subject=>"",body=>"I didn't understand you!",type=>"chat",priority=>10); $dbQry->finish(); &keepItGoing; } } } sub gotIQ { print "iq\n"; } sub trimSpaces { my $string = $_[0]; $string =~ s/^\s+//; #remove leading spaces $string =~ s/\s+$//; #remove trailing spaces return $string; } sub keepItGoing { print "keepItGoing!\n"; my $proc = $jabberBot->Process(1); while(defined($proc) && $proc != 1) { $proc = $jabberBot->Process(1); } } sub killBot { print "killing\n"; $jabberBot->MessageSend(to=>$_[0]->GetFrom(),subject=>"",body=>"Logging Out!",type=>"chat",priority=>10); $jabberBot->Process(1); $jabberBot->Disconnect(); exit; }

POE有一些非常好的事件框架。我不知道Jabber(POE :: Component :: Jabber)有多好,但它可能值得一看。
答案 1 :(得分:4)
AnyEvent::XMPP非常全面,并且由于它使用AnyEvent,因此可以在任何带有受支持循环的事件驱动应用程序中运行(AnyEvent's own,Event,{{ 3}},EV,Tk,偶数Glib/Gtk)。

我认为你可以通过这样做来使你的例子工作:
0 while $jabber->Process
话虽如此,我强烈建议使用适当的事件处理框架,例如AnyEvent(我个人最喜欢的)或POE(传统的选择)。
