Net::HTTP::NB(3p)

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

VERSION
version 6.19

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.
