plex subscription

subscriber registers the event that he wants to subscribe to the dispatch center, when the event triggers, the Publisher publishes the event to the Dispatch center (incidentally), and the dispatch center uniformly dispatches the subscriber to the dispatch center's processing code.For example, an interface is a real-time display of weather, it subscribes to weather events (registered to the dispatch center, including handlers), when the weather changes (timing to obtain data), as the publisher t

New users focus on the public platform and will generate a subscription event, the subscribe event , which does not respond appropriately to this event in the default code.After the new user has focused on the public platform, it may be interesting to know what features the platform provides and how to use it, which is a "user's manual" for the platform.This article will detail the processing of the Subscribe event, and respond to the corresponding in

First, publish the subscription messageA publish Subscription (PUB/SUB) is a message communication pattern that is primarily designed to decouple the coupling between a message publisher and a subscriber, and Redis acts as a pub/sub server, with the ability to route messages between subscribers and publishers. Subscribers can subscribe to Redis server for the type of message they are interested in by using

Command line version Open cmd, switch to the Redis installation directory, the directory should have Redis-cli.exe, Redis-server.exe, redis.conf and other files.

What is message-oriented middleware? The publishing and subscription of point-to-point message-oriented middleware is asynchronous communication. Case: Use redis for publishing and subscriptionRedis publish and subscribe Redis pub/sub is a message communication mode: the sender (pub) sends messages, and the subscriber (sub) receives messages. Redis clients can subscribe to any number of channels. Shows the relationship between channel channel1 a

JMS is a Java Message Service. JMS clients can transmit messages asynchronously through the JMS service. JMS supports two message models: point-to-point (P2P) and publish/subscribe (pub/Sub), that is, point-to-point and publish subscription models.P2P The P2P model has the following concepts: queue, sender, and receiver ). Each message is sent to a specific queue, and the receiver obtains the message from the queue. The queue retains messages until

As an example of the previous section, when an order is generated, the background n systems need to be linked, but there is a prerequisite to receive order information, then we need to publish a producer's message to n consumers.Producers: try {//create the Connec

There is no such implementation method, trouble to give a train of thought, the subscription number can not get the user's information, also did not generate the parameters of the two-dimensional code function, do not need to two-dimensional code, to achieve a similar process on the line, to seek ideas, thank you!
