How to read all message from Azure Service Bus topic using Python?

问题

I want to read all messages from azure service bus using python. Currently it fetch only one message.

from azure.servicebus.control_client import ServiceBusService, Message, Topic, Rule, DEFAULT_RULE_NAME

    bus_service = ServiceBusService(
        service_namespace='<NameSpace>',
        shared_access_key_name='<KeyName>',
        shared_access_key_value='<ConnectionString>')

msg = bus_service.receive_subscription_message('topic', 'msglist', peek_lock=True)
print(msg.body)

How can I get all the message in bulk from the topic with python 3

回答1:

This is possible by using a Receiver object which supports batch operations. Refer this sample which showcases how to get this object for a subscription.

To guarantee you get batches of messages, you have to set the prefetch argument of get_receiver() to your batch size and consequently the max_batch_size argument of fetch_next() to the same.
