Proposed Changes
Add MQTT as a
Message
format.Description
This commit adds
MQTT
to the supported transport protocols by adding aBinding
and theMQTTMessage<T>
type, extending the baseMessage
type, adding the MQTT fields forpayload
,PUBLISH
andUser Properties
. Thepayload
field directly maps toMessage#body
, whileUser Properties
roughly maps toMessage#headers
, even though the properties here are not formatted with ace-
prefix like other transport protocols. This is per the spec. See: https://github.com/cloudevents/spec/blob/v1.0.1/mqtt-protocol-binding.md. ThePUBLISH
property is there primarily to support the"Content type"
and perhaps should be typed better. Feedback welcome.
