Publisher/subscriber Subscription-Release modeThe follow-up will continue to collate some of these years to do some of the pre-research demo, and some of the leading-edge technology, with everyone to study technology and common progress.There are many ways to implement a publish subscription, the following is mainly about the publication of the subscription in WC
A publish Subscription (PUB/SUB) is a message communication pattern that is primarily designed to decouple the coupling between a message publisher and a message subscriber, which is similar to the observer pattern in design patterns. Pub/sub not only solves the direct code level coupling between publishers and subscribers, but also solves the coupling between the two on the physical deployment. As a pub/sub server, Redis serves as a message routing f

My idea is to obtain the unique ID of the current subscription number when a user places an order in one of the subscription numbers. Insert an identifier to the database when an order is generated. There is a requirement that multiple subscription numbers share one website. However, when placing an order, make a difference. So, I hope you will pass...
