Abstract

The invention relates to the technical field of system updating, and provides a method for remotely and instantly updating a client based on an MQTT protocol, which comprises the following steps: step 100, a background server obtains a client updating file uploaded by an administrator, and the background server sends an instruction for querying the client needing to be updated to the dbsql database according to the client updating file; step 200, the bsql database returns the client information needing to be updated to the background server; step 300, the background server forms a client list to be updated, then the background server sends the update push message to the MQTT server according to the client list to be updated; step 400, the MQTT server issues the update push message to the client to be updated; and step 500, the to-be-updated client obtains the client update file from the FTP server, and system update is carried out. According to the invention, the client can be remotely and instantly updated, and the updating efficiency of the client is improved.

Description

technical field [0001] The invention relates to the technical field of system update, in particular to a method for remote real-time update of a client based on the MQTT protocol. Background technique [0002] WebSphere MQ Telemetry Transport (MQTT) is an asynchronous message transport protocol, and WebSphere MQ Telemetry Transport (MQTT) is a lightweight broker-based publish / subscribe message transport protocol. [0003] The push service is essentially that the server actively sends messages and data to the client, rather than the client actively going to the server to request data. This kind of push only requires that after the client is connected to the server, if there is data, the server will immediately send the data to the client. The clients here can be of various types, such as common browsers, mobile applications, and so on. After the client receives the message, it will automatically download the update file in the received message, so as to achieve remote real-...
