Net::HTTP::NB − Non−blocking HTTP client
use Net::HTTP::NB;
my $s = Net::HTTP::NB−>new(Host => "www.perl.com") || die $@;
$s−>write_request(GET => "/");
use IO::Select;
my $sel = IO::Select−>new($s);
READ_HEADER: {
die "Header timeout" unless $sel−>can_read(10);
my($code, $mess, %h) = $s−>read_response_headers;
redo READ_HEADER unless $code;
}
while (1) {
die "Body timeout" unless $sel−>can_read(10);
my $buf;
my $n = $s−>read_entity_body($buf, 1024);
last unless $n;
print $buf;
}
Same interface as "Net::HTTP" but it will never try multiple reads when the read_response_headers() or read_entity_body() methods are invoked. This make it possible to multiplex multiple Net::HTTP::NB using select without risk blocking.
If read_response_headers() did not see enough data to complete the headers an empty list is returned.
If read_entity_body() did not see new entity data in its read the value −1 is returned.
