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.
QtCoap.ResponseCode.Continue
Indicates that the transfer of the current block was successful, and the server will send more blocks.
QtCoap.ResponseCode.BadRequest
The request was not recognized. This response code corresponds to HTTP 400 “Bad Request”.
QtCoap.ResponseCode.Unauthorized
The client is not authorized to perform the requested action. This response code corresponds to HTTP 401 “Unauthorized”.
QtCoap.ResponseCode.BadOption
The request could not be understood by the server due to unrecognized options.
QtCoap.ResponseCode.Forbidden
Access to this resource is forbidden. This response code corresponds to HTTP 403 “Forbidden”.
QtCoap.ResponseCode.NotFound
The resource requested was not found. This response code corresponds to HTTP 404 “Not Found”.
QtCoap.ResponseCode.MethodNotAllowed
The server does not allow the method used for the URL requested. This response code corresponds to HTTP 405 “Method Not Allowed” but with no parallel to the “Allow” header field.
QtCoap.ResponseCode.NotAcceptable
No resource satisfying the request’s acceptance criteria was found. This response code corresponds to HTTP 406 “Not Acceptable”, but with no response entity.
QtCoap.ResponseCode.RequestEntityIncomplete
The server has not received all blocks, of the request body, that it needs to proceed.
QtCoap.ResponseCode.PreconditionFailed
Preconditions given in the request header fields evaluated to
false
when tested on the server. This response code corresponds to HTTP 412 “Precondition Failed”.QtCoap.ResponseCode.RequestEntityTooLarge
The request payload is larger than the server is willing or able to process. This response code corresponds to HTTP 413 “Request Entity Too Large”.
QtCoap.ResponseCode.UnsupportedContentFormat
The payload is in a format not supported by this method on the target resource. This response code corresponds to HTTP 415 “Unsupported Media Type”.
QtCoap.ResponseCode.InternalServerFault
The server encountered an unexpected condition that prevented it from fulfilling the request. This response code corresponds to HTTP 500 “Internal Server Error”.
QtCoap.ResponseCode.NotImplemented
The server does not support the functionality required to fulfill the request. This response code corresponds to HTTP 501 “Not Implemented”.
QtCoap.ResponseCode.BadGateway
An error occurred with an upstream server. This response code corresponds to HTTP 502 “Bad Gateway”.
QtCoap.ResponseCode.ServiceUnavailable
The service is currently unavailable. This response code corresponds to HTTP 503 “Service Unavailable”.
QtCoap.ResponseCode.GatewayTimeout
The server, while acting as a gateway or proxy, did not receive a timely response from an upstream server. This response code corresponds to HTTP 504 “Gateway Timeout”.
QtCoap.ResponseCode.ProxyingNotSupported
The server is unable or unwilling to act as a forward-proxy for the URI specified in the Proxy-Uri Option or using the scheme specified in Proxy-Scheme.
QtCoap.ResponseCode.InvalidCode
An invalid response code.
- PySide6.QtCoap.QtCoap.Error#
Indicates the error condition found during processing of the request.
Constant
Description
QtCoap.Error.Ok
No error condition.
QtCoap.Error.HostNotFound
The remote host name was not found.
QtCoap.Error.AddressInUse
The address is already in use.
QtCoap.Error.TimeOut
The response did not arrive in time.
QtCoap.Error.BadRequest
The request was not recognized.
QtCoap.Error.Unauthorized
The client is not authorized to perform the requested action.
QtCoap.Error.BadOption
The request could not be understood by the server due to one or more unrecognized or malformed options.
QtCoap.Error.Forbidden
Access to this resource is forbidden.
QtCoap.Error.NotFound
The resource requested was not found.
QtCoap.Error.MethodNotAllowed
The server does not allow the method used for the URL requested.
QtCoap.Error.NotAcceptable
