我想阅读我的套接字并在它们上做一个“ getline”。
my @socket1;
$socket1[0] = IO::Socket::INET->new(
Type => SOCK_STREAM,
PeerAddr => "127.0.0.1",
Proto => "tcp",
PeerPort => $dbase_param{camera_stream}
) or die "Cannot open socket on port " . $dbase_param{camera_stream} . ".\n";
print { $socket1[0] } "\n";
my $ligne = <$socket1[0]>;
while ( !( $ligne =~ /Content-Length:/ ) ) {
$ligne = <$socket1[0]>;
}
它将告诉我第二个
Use of uninitialized value $ligne in pattern match (m//)
我不明白
最佳答案
尖括号也用于glob()
,
perl -MO=Deparse -e '$ligne = <$socket1[0]>;'
use File::Glob ();
$ligne = glob($socket1[0]);
因此,如果您不使用普通标量作为套接字,则可以使用
readline()
使其更加明确,$ligne = readline($socket1[0]);
