Bidirectional real-time communication system and method based on WebSocket and message queue

Abstract

The invention discloses a bidirectional real-time communication system and method based on a WebSocket and a message queue and relates to the technical field of communication. The problem that an existing real-time communication scheme based on the WebSocket protocol is liable to result in the condition that rear end service and a database need to bear a great deal of concurrent pressure is solved. According to the technical scheme key point, the system comprises a server and clients. The server comprises a marking module which is used for establishing unique identifications for the clients connected with the server, and an index module which is used for establishing indexes according to the unique identifications established by the marking module, wherein the indexes are used for positioning positions of the clients in WebSocket service. The server receives messages issued by a receiving message producer from a subscribed message queue in a message queue consumer mode and pushes the received messages to the clients according to the indexes. The server receives the messages passively and then pushes the messages to the corresponding clients, so the performance problem resulting from polling is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for realizing two-way real-time communication based on WebSocket and message queue. Background technique [0002] Currently, the most widely used network protocol on the Internet is Hypertext Transfer Protocol (HTTP, HyperText Transfer Protocol). The working principle of HTTP is that the client keeps sending Ajax requests to the server (that is, let the client send a request every few seconds to ask the server if there is new information), and the server immediately returns the response information and closes the connection after receiving the request . At this point, the connection between the client and the server is terminated. If the client does not obtain the expected data, it needs to repeat the above steps to establish a connection again. [0003] Although the client can obtain the latest data as soon as possible (depending on the polling inter...

AI Technical Summary

Problems solved by technology

[0007] The first object of the invention is to provide a system for two-way real-time communication based on WebSocket and message queue, which has the advantage that the server receives messages in a passive manner, which solves the performance problem caused by polling;

[0008] The second purpose of the invention is to provide a method for two-way real-time communication based on WebSocket and message queues. The advantage is that the server receives messages in a passive manner, which ensures system performance and solves the problem that WebSocket services cannot be located when they are deployed in a cluster. The problem with the position of the client in the WebSocket service
