Disconnect Peer

API reference for diameter.message.commands.disconnect_peer.

This module contains Disconnect-PeerConnection Request and Answer messages, implementing AVPs documented in rfc6733.

DisconnectPeer

DisconnectPeer(header: MessageHeader = None, avps: list[Avp] = None)

Bases: DefinedMessage

A Disconnect-Peer message.

This message class lists message attributes based on the current RFC6733 as python properties, acessible as instance attributes. AVPs not listed in the base protocol can be retrieved using the DisconnectPeer.find_avps search method.

Examples:

AVPs accessible either as instance attributes or by searching:

>>> msg = Message.from_bytes(b"...")
>>> msg.origin_realm
b'mvno.net'
>>> msg.find_avps((AVP_ORIGIN_REALM, 0))
[b'mvno.net']

When diameter message is decoded using Message.from_bytes, it returns either an instance of DisconnectPeerRequest or DisconnectPeerAnswer automatically:

>>> msg = Message.from_bytes(b"...")
>>> assert msg.header.is_request is True
>>> assert isinstance(msg, DisconnectPeerRequest)

When creating a new message, the DisconnectPeerRequest or DisconnectPeerAnswer class should be instantiated directly, and values for AVPs set as class attributes:

>>> msg = DisconnectPeerRequest()
>>> msg.origin_realm = b"mvno.net"

Other, custom AVPs can be appended to the message using the DisconnectPeer.append_avp method, or by overwriting the avp attribute entirely. Regardless of the custom AVPs set, the mandatory values listed in RFC6733 must be set, however they can be set as None, if they are not to be used.

Warning

Every AVP documented for the subclasses of this command can be accessed as an instance attribute, even if the original network-received message did not contain that specific AVP. Such AVPs will be returned with the value None when accessed.

Every other AVP not mentioned here, and not present in a network-received message will raise an AttributeError when being accessed; their presence should be validated with hasattr before accessing.
