A distributed state synchronization method based on http and websocket

Abstract

The invention discloses a distributed state synchronization method for HTTP and WebSocket collaboration, which is characterized in that it includes: step 1: WebSocket server cluster initialization, step 2: reconstructing the URL of the WebSocket server cluster, and step 3: assigning a URL to each client A WebSocket session, step 4: check whether the long connection is normal, step 5: determine the business status change request; step 6: call the business server to process the request, and feed back the result to the client, step 7: send the request to the WebSocket server Node, step 8: close the long connection. Using the WebSocket server instead of the original client to send heartbeat detection, without using messages or external storage, it has the effect of simple deployment and easy expansion, and at the same time solves the functional requirements of different scenarios.

Description

A Distributed State Synchronization Method for HTTP and WebSocket Collaboration technical field The present invention relates to the technical field of data communication, particularly relate to a kind of distributed distributed coordination of HTTP and WebSocket State synchronization method. Background technique In the real-time communication fields such as audio and video, screen sharing, for efficient collaboration between users, a real-time state is required. Dynamic synchronization system, compatible with browsers and APPs at the same time. WebSocket uses a long connection, which can realize the instant connection between the server and the client. time communication, but the client requests the server, since the operation result cannot be sensed in real time by using asynchronous messages, the operation may fail Wrong; using the WebSocket protocol alone requires an additional authentication mechanism. In the aspect of WebSocket long connection, the prior art...

Problems solved by technology

[0005] Patents CN2019104677729-distributed push method for single-user multi-site login based on websocket, CN2019113338150-distributed server cluster interaction method and device based on WebSocket, both provide technical solutions based on distributed scenarios, but need to use messages or storage , not concise enough for practical application

At the same time, the existing technology only uses one protocol at the same time, and the scalability is limited
