Notes

Note

  • This module requires the pika python library https://pika.readthedocs.io/.

  • Pika is a pure-Python implementation of the AMQP 0-9-1 protocol that tries to stay fairly independent of the underlying network support library.

  • This module is tested against RabbitMQ. Other AMQP 0.9.1 protocol based servers may work but not tested/guaranteed.

  • The certificate authentication was tested with certificates created via https://www.rabbitmq.com/ssl.html#automated-certificate-generation and RabbitMQ configuration variables ssl_options.verify = verify_peer & ssl_options.fail_if_no_peer_cert = true.
