NAME Net::AMQP - Advanced Message Queue Protocol (de)serialization and representation

SYNOPSIS use Net::AMQP;

  Net::AMQP::Protocol->load_xml_spec('amqp0-8.xml');

  ...

  my @frames = Net::AMQP->parse_raw_frames(\$input);

  ...

  foreach my $frame (@frames) {
      if ($frame->can('method_frame') && $frame->method_frame->isa('Net::AMQP::Protocol::Connection::Start')) {
          my $output = Net::AMQP::Frame::Method->new(
              channel => 0,
              method_frame => Net::AMQP::Protocol::Connection::StartOk->new(
                  client_properties => { ... },
                  mechanism         => 'AMQPLAIN',
                  locale            => 'en_US',
                  response          => {
                      LOGIN    => 'guest',
                      PASSWORD => 'guest',
                  },
              ),
          );
          print OUT $output->to_raw_frame();
      }
  }

DESCRIPTION This module implements the frame (de)serialization and representation of the Advanced Message Queue Protocol (http://www.amqp.org/). It is to be used in conjunction with client or server software that does the actual TCP/IP communication.

CLASS METHODS parse_raw_frames Net::AMQP->parse_raw_frames($binary_payload)

Given a scalar reference to a binary string, return a list of
Net::AMQP::Frame objects, consuming the data in the string. Croaks on
invalid input.

AMQP VERSIONS AMQP 0-8 is fully supported.

AMQP 0-9, 0-9-1, and 0-10 are usably supported. There are
interoperability issues with table encodings because the standard
disagrees with the dialects of major implementations (RabbitMQ and
Qpid). For now, Net::AMQP limits itself to universally agreed table
elements. See <http://www.rabbitmq.com/amqp-0-9-1-errata.html> for
details.

AMQP 1.0 has not been tested.

TODO Address the dialect problem, either via modified spec files that completely control the wire protocol, or by programmatic request. The former has precedent (viz "qpid.amqp0-8.xml" in spec), but could cause a combinatorial explosion as more brokers and versions are added. The latter adds interface complexity.
