NAME

Net::HTTP::NB - Non-blocking HTTP client

VERSION

version 6.23

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.
