Decentralized data subscription and distribution method, server and client

The invention discloses a decentralized data subscription and distribution method and system, and the method is characterized in that the method comprises the following steps: 1, building the network connection between a client and a server in the data subscription and distribution system, and deploying a plurality of application programs in the server; step 2, identifying data requests from the client based on the server, aggregating and classifying the data requests, and compiling identification codes; and step 3, respectively obtaining combined data contents from the plurality of application programs based on the identification codes, and issuing the combined data contents to the corresponding clients sending the data requests in a multiplexing mode. The method disclosed by the invention is ingenious in conception, relatively low in network load rate, relatively high in transmission and processing speed and controllable in network occupancy rate, and the data processing pressure of the server is greatly re
