A data processing method and system based on websocket long connection

Abstract

The invention discloses a data processing method and system based on a Websocket long connection. The method includes: after a terminal device is connected to the network, it logs in to a ws communication address provided by a server through a login password to establish a Websocket long connection with the server; the login password is generated based on an authorization code ; The authorization code is generated based on a device code used to identify the terminal device type and / or terminal device model; based on the Websocket persistent connection, the terminal device and the server perform message interaction according to a preset JSON format message. The data processing method and system based on the Websocket persistent connection of the present invention can realize the two-way communication between the terminal equipment and the server; at the same time, it can ensure that the data in the two-way communication is not lost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data processing method and system based on Websocket persistent connection. Background technique [0002] In the early stage of traditional Internet of Things communication, HTTP short connections were mostly used. Specifically, the terminal device regularly requests the server to realize data upload and delivery interaction. With http short connection, only a single channel of the terminal device can be used to regularly send requests to the server. If the timing time is too long, the real-time performance will be poor, and if the timing time is too short, the pressure on the server will increase. Therefore, this http short connection communication method Basically, it is difficult to apply to terminal equipment with high real-time requirements, such as security, attendance, witness and other terminal equipment, and on this basis, it is impossible to monitor the online ...

With http short connection, only a single channel of the terminal device can be used to regularly send requests to the server. If the timing time is too long, the real-time performance will be poor, and if the timing time is too short, the pressure on the server will increase. Therefore, this http short connection communication method It is basically difficult to apply to terminal equipment with high real-time requirements, such as security, attendance, witness and other terminal equipment, and on this basis, it is impossible to monitor the online status of terminal equipment in real time

[0003] At present, most Internet of Things industries adopt low-power mqtt protocol more. For data uploaded by terminal devices, the server needs to monitor each terminal device. , basically depends on the mqtt qos attribute, once there is a problem with the underlying layer, there may be a problem of data loss
