[signal]
void
QCoapReply::
aborted
(const
QCoapToken
&
token
)
This signal is emitted when the request is aborted or the reply is deleted. Its token parameter is the token of the exchange that has been aborted.
注意： 若 QCoapReply is deleted while not finished, both aborted() and finished () signal will be emitted immediately before the QCoapReply is destroyed. Given the QCoapReply may have been deleted when receiving the signal, you should not rely on the sender () object to be still valid.
[signal]
void
QCoapReply::
error
(
QCoapReply

reply
,
QtCoap::Error
error
)
This signal is emitted whenever an error occurs and is followed by the finished () 信号。
Its reply parameters is the QCoapReply itself for convenience, and the error parameter is the error received.

[signal]
void
QCoapReply::
finished
(
QCoapReply

reply
)
This signal is emitted whenever the corresponding request finished, whether successfully or not. When a resource is observed, this signal will only be emitted once, when the observation ends.
The reply parameter is the QCoapReply itself for convenience.
注意： 若 QCoapReply is deleted while not finished, both aborted () and finished() signal will be emitted immediately before the QCoapReply is destroyed. Given the QCoapReply may have been deleted when receiving the signal, you should not rely on the reply to be still valid.
