DESCRIPTION

declare_queue

bind_queue

Binds a queue to an exchange, with a routing key.

Arguments:

queue

The name of the queue to bind

exchange

The name of the exchange to bind

routing_key

unbind_queue

purge_queue

Flushes the contents of a queue.

delete_queue

Deletes a queue. The queue may not have any active consumers.

publish

Publish a message to an exchange

Arguments:

body

The text body of the message to send.

header

Customer headers for the message (if any).

exchange

The name of the exchange to send the message to.

routing_key

The routing key with which to publish the message.

on_ack

Callback (if any) for confirming acknowledgment when in confirm mode.

consume

Subscribe to consume messages from a queue.

Arguments:

on_consume

Callback called with an argument of the message which has been consumed.

on_cancel

Callback called if consumption is canceled. This may be at client request or as a side effect of queue deletion. (Notification of queue deletion is a RabbitMQ extension.)

consumer_tag

Identifies this consumer, will be auto-generated if you do not provide it, but you must supply a value if you want to be able to later cancel the subscription.

on_success

Callback called if the subscription was successful (before the first message is consumed).

on_failure

Callback called if the subscription fails for any reason.

cancel

Cancel a queue subscription.

Note that the cancellation will not take place at once, and further messages may be consumed before the subscription is cancelled. No further messages will be consumed after the on_success callback has been called.

Arguments:

consumer_tag

Identifies this consumer, needs to be the value supplied when the queue is initially consumed from.

on_success

Callback called if the subscription was successfully cancelled.

on_failure

Callback called if the subscription could not be cancelled for any reason.

get

Try to get a single message from a queue.

Arguments:

queue

Mandatory. Name of the queue to try to receive a message from.

on_success

Will be called either with either a message, or, if the queue is empty, a notification that there was nothing to collect from the queue.

on_failure

This callback will be called if an error is signalled on this channel.

ack

qos

confirm

Put channel into confirm mode. In confirm mode, publishes are confirmed by the server, so the on_ack callback of publish works.

recover

select_tx

commit_tx

rollback_tx
