Detailed Description#

PySide6.QtCoap.QtCoap.ResponseCode#

This enum represents the response code from the CoAP protocol, as defined in RFC 7252 and RFC 7959 .

Constant

Description

QtCoap.ResponseCode.EmptyMessage

The response code for an empty message.

QtCoap.ResponseCode.Created

The request was successful and has resulted in new resources being created. This response code corresponds to HTTP 201 “Created”.

QtCoap.ResponseCode.Deleted

The resource has been successfully deleted. This response code corresponds to HTTP 204 “No Content” but is only used in response to requests that cause the resource to cease being available, such as DELETE and, in certain circumstances, POST.

QtCoap.ResponseCode.Valid

This response code is related to HTTP 304 “Not Modified” but is only used to indicate that the response identified by the entity-tag given in the ETag Option is valid.

QtCoap.ResponseCode.Changed

The resource has been successfully modified. This response code corresponds to HTTP 204 “No Content” but is only used in response to POST and PUT requests.

QtCoap.ResponseCode.Content

The request has succeeded. This response code corresponds to HTTP 200 “OK” but is only used in response to GET requests.
