AmqpMessageProperties Class

  • Reference

Message properties. The properties that are actually used will depend on the service implementation. Not all received messages will have all properties, and not all properties will be utilized on a sent message. Please refer to the AMQP spec: http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-messaging-v1.0-os.html#type-properties for more information on the message properties.

Keyword-Only Parameters

Name Description
message_id
Optional[Union[str, bytes, UUID]]

Message-id, if set, uniquely identifies a message within the message system.

A broker MAY discard a message as a duplicate if the value of the message-id matches that of a previously received message sent to the same node.
user_id
Optional[Union[str, bytes]]

The identity of the user responsible for producing the message. The client sets this value, and it MAY be authenticated by intermediaries.
to
Optional[Union[str, bytes]]

The to field identifies the node that is the intended destination of the message. On any given transfer this might not be the node at the receiving end of the link.
subject
Optional[Union[str, bytes]]

A common field for summary information about the message content and purpose.
reply_to
Optional[Union[str, bytes]]

The address of the node to send replies to.

content_encoding
Optional[Union[str, bytes]]

The content-encoding property is used as a modifier to the content-type.
creation_time
Optional[int]

An absolute time when this message was created.
absolute_expiry_time
Optional[int]

An absolute time when this message is considered to be expired.
group_id
Optional[Union[str, bytes]]
