basic_publish back is None

[Alan Lee]

channel = connection.channel()

result = channel.basic_publish(exchange=exchange_name, routing_key=routing_key, body=message_body,

properties=pika.BasicProperties(
delivery_mode=2
))

The result is always None, even if the message has been successfully sent.

connection = pika.BlockingConnection(
pika.ConnectionParameters(host='172.26.22.201',
credentials=pika.PlainCredentials('guest', '123456'),
virtual_host="/"))
channel = connection.channel()

channel.confirm_delivery()

if channel.basic_publish(exchange='exchange.direct.order', routing_key='order', body='Hello, RabbitMQ!'):
print("sucessful delivery")
else:
print("failed delivery")

always None

basic_publish returns None, or will raise one of two exceptions. Just ensure the messages are sent as Mandatory and the channel mode is set to confirm, then catch these two to handle unroutable or returned messages, otherwise I think you can assume the message was publish successfully.
