NAME¶
Net::HTTP::NB - Non-blocking HTTP client
SYNOPSIS¶
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; }
DESCRIPTION¶
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.
