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.
