【问题描述】:
我最近尝试在Perl中制作一个游戏服务器控制器,我想启动,停止和查看游戏服务器已经输出的文本,这是我目前的:
#!/usr/bin/perl -w
use IO::Socket;
use Net::hostent; # for OO version of gethostbyaddr
$PORT = 9050; # pick something not in use
$server = IO::Socket::INET->new( Proto => 'tcp',
LocalPort => $PORT,
Listen => SOMAXCONN,
Reuse => 1);
die "can't setup server" unless $server;
print "[Server $0 accepting clients]\n";
while ($client = $server->accept()) {
$client->autoflush(1);
print $client "Welcome to $0; type help for command list.\n";
$hostinfo = gethostbyaddr($client->peeraddr);
printf "[Connect from %s]\n", $hostinfo->name || $client->peerhost;
print $client "Command? ";
while ( <$client>) {
next unless /\S/; # blank line
if (/quit|exit/i) {
last; }
elsif (/some|thing/i) {
printf $client "%s\n", scalar localtime; }
elsif (/start/i ) {
open RSPS, '|java -jar JARFILE.jar' or die "ERROR STARTING: $!\n";
print $client "I think it started...\n Say status for output\n"; }
elsif (/stop/i ) {
print RSPS "stop";
close(RSPS);
print $client "Should be closed.\n"; }
elsif (/status/i ) {
$output = <RSPS>;
print $client $output; }
else {
print $client "Hmmmm\n";
}
} continue {
print $client "Command? ";
}
close $client;
}
我无法从管道中读取,有什么想法吗?
谢谢!
