Publish.PacketID is not consist with puback.PacketID

或者是不是可以参考下emqtt的实现，Publish消息生成一个messageID，收的puback 后通过PacketID关联下messageID？

Question(from google translate):
After the sender pushes the message, the pushback PacketID returned by the subscriber after receiving the message is inconsistent with the PacketID of the sender's push message.

Due to the inconsistency of the two PacketIDs, the sender cannot determine whether the number has been successfully received by the subscriber through the puback message. I found that the PacketID of the message was reset deliberately in the code before it was delivered to the subscriber. Is it because there are multiple subscribers to a certain topic that different PacketIDs are generated? If this is the case, is it possible to consider maintaining a messageID for each message on the server side to determine whether the subscriber has received it, while retaining Publish.PacketID.

@blessmylovexy Having a messageID for each message sounds reasonable, but If you want to get notified when the message has been delivered, I suggest you should use the OnMsgDelivered hooks.
OnPuback hook will only work with QoS1 the message, QoS0 and QoS2 message do not use Puback.
I've been a little busy these days, but we can discuss this and I can help you if you want to contribute.:)
