我正在使用 perl 中的套接字连接编写一个简单的代码:
$sock = new IO::Socket::INET(
PeerAddr => '192.168.10.7',
PeerPort => 8000,
Proto => 'tcp');
$sock or die "no socket :$!";
然后使用循环发送数据:
while...
print $sock $str;
...loop
有没有办法在循环中插入一个命令来检查连接?就像是:
while...
socket is up?
yes => send data
no => connect again and the continue with loop
...loop
编辑添加我的代码:
my $sock = new IO::Socket::INET(
PeerAddr => '192.168.10.152',
PeerPort => 8000,
Proto => 'tcp');
$sock or die "no socket :$!";
open(my $fh, '<:encoding(UTF-8)', 'list1.txt')
or die "Could not open file $!";
while (my $msdn = <$fh>) {
my $port="8000";
my $ip="192.168.10.152";
unless ($sock->connected) {
$sock->connect($port, $ip) or die $!;
}
my $str="DATA TO SEND: " . $msdn;
print $sock $str;
}
close($sock);
