Consuming messages in RabbitMQ - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to consume a message from the queue.

RabbitMQ

channel.basic_consume(queue='task_queue', on_message_callback=[1], auto_ack=True)

Drag options to blanks, or click blank then click option'

Acallback_function

Csend_message

Ddeclare_queue

💡 Hint

Common Mistakes

Using a function that sends messages instead of processing them.

Passing a queue name instead of a function.

The on_message_callback parameter requires a function that will be called when a message is received. This function processes the message.

Complete the code to start consuming messages.

RabbitMQ

Drag options to blanks, or click blank then click option'

Bbasic_publish

Cstop_consuming

Dstart_consuming

Attempts:

💡 Hint

Common Mistakes

Using basic_publish which sends messages instead of receiving.

Calling stop_consuming which stops the consumer.

The start_consuming() method tells the channel to begin waiting for messages and call the callback when messages arrive.

3fill in blank

hard

Fix the error in the callback function to acknowledge the message.

RabbitMQ

def callback(ch, method, properties, body):
    print(f"Received {body}")
    ch.basic_ack(delivery_tag=[1])

Drag options to blanks, or click blank then click option'

Amethod.delivery_tag

Bbody

Cproperties.delivery_tag

Dch.delivery_tag

Attempts:

💡 Hint

Common Mistakes

Using the message body as the delivery tag.

Trying to access delivery_tag from the wrong parameter.

The delivery_tag is part of the method parameter and is used to acknowledge the specific message.

4fill in blank

hard

Fill both blanks to consume messages with manual acknowledgment.

RabbitMQ

channel.basic_consume(queue=[1], on_message_callback=[2], auto_ack=False)

Drag options to blanks, or click blank then click option'

A'task_queue'

Bcallback

C'logs'

Dsend_message

Attempts:

💡 Hint

Common Mistakes

Using a wrong queue name.

Passing a function that does not process messages.

The queue name must be the one declared earlier, and the callback function processes the messages. Setting auto_ack=False means you manually acknowledge messages.

5fill in blank

hard

Fill all three blanks to set up a consumer with a callback and start consuming.

RabbitMQ

channel.basic_consume(queue=[1], on_message_callback=[2], auto_ack=[3])
channel.start_consuming()

Drag options to blanks, or click blank then click option'

A'task_queue'

Bcallback

CFalse

DTrue

💡 Hint

Common Mistakes

Setting auto_ack to True when manual ack is needed.

Using wrong queue or callback names.

This sets up consuming from the 'task_queue' with the callback function and manual acknowledgment (auto_ack=False), then starts the consumer loop.
