QtCoap::Error::NotImplemented 16 The server does not support the functionality required to fulfill the request.
QtCoap::Error::BadGateway 17 An error occurred with an upstream server.
QtCoap::Error::ServiceUnavailable 18 The service is currently unavailable.
QtCoap::Error::GatewayTimeout 19 The server, while acting as a gateway or proxy, did not receive a timely response from an upstream server it needed to access in order to complete the request.
QtCoap::Error::ProxyingNotSupported 20 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::Error::Unknown 21 出现未知错误。

QtCoap::DefaultSecurePort 5684 The default port used for the secure transmission.

enum class QtCoap:: ResponseCode

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

常量 描述
QtCoap::ResponseCode::EmptyMessage 0x00 The response code for an empty message.
QtCoap::ResponseCode::Created 0x41 The request was successful and has resulted in new resources being created. This response code corresponds to HTTP 201 "Created".
QtCoap::ResponseCode::Deleted 0x42 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 0x43 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.
