producer confirm_delivery

[edsionxuanxuan]

hi:

version: 1.3.2
os: windows10
python: 3.10

I want to ask , in the new version of pika, the producer confirm mode, producter-->exchange, exchange-->queue, only need to use try... except.. to catch busic_publish? If producter-->exchange fails, catch NackError, then exchange-->queue, catch UnroutableError?
old version:

def on_delivery_confirmation(method_frame):
    confirmation_type = method_frame.method.NAME
    if confirmation_type == 'Basic.Ack':
        print("Message published and confirmed!")
    else:
        print("Message not confirmed!")
channel.confirm_delivery()
channel.basic_publish(exchange='', routing_key='queue_name', body=message,
                      properties=pika.BasicProperties(content_type='text/plain'))
channel.add_on_return_callback(on_delivery_confirmation)

new version:

    channel.confirm_delivery()
    
    try:
        channel.basic_publish(exchange='test_exchange',
                routing_key='standard_key',
                body=json.dumps(message),
                properties=pika.BasicProperties(content_type='application/json', delivery_mode=DeliveryMode.Persistent))
        print('Message publish was confirmed')
    except pika.exceptions.UnroutableError:
        print('exchange routing Message to queue could not be confirmed')
    except pika.exceptions.NackError:
        print("product send Message to exchange could not be confirmed ")

thanks

Hello, could you please provide a git repository with complete code I can run?

hey,
so there is no concept of basic.ack and basic.nack in the newer version in the publisher confirms?

What makes you think that? Of course this library supports basic.ack and basic.nack.
