MQTT-based theme subscription forwarding management method and device, equipment and storage medium

Abstract

The invention discloses an MQTT-based theme subscription forwarding management method, apparatus and device, and a storage medium. The method comprises the following steps: analyzing a domain name of an MQTT cloud server into a local IP address through a control server according to domain name hijacking; controlling a first Internet of Things terminal to acquire the analyzed local IP address, and establishing MQTT connection with a server according to the local IP address; controlling the first Internet of Things terminal to carry out MQTT server theme subscription on the server; controlling the server to establish an MQTT connection with the MQTT cloud server; controlling the server to send locally stored MQTT theme subscription information to the MQTT cloud server; controlling the server to inform the first Internet of Things terminal of successful connection with the MQTT cloud server according to a sending result; and controlling the first Internet of Things terminal to resend the terminal state information. According to the MQTT-based theme subscription forwarding management method provided by the invention, the time delay can be shortened, the network flow can be reduced, and the efficiency of an application program and the security of data can be improved.

Description

technical field [0001] The present invention relates to the field of printing technology, in particular to an MQTT-based topic subscription and forwarding management method, device, device and storage medium. Background technique [0002] At present, the Internet of Things has pervaded our lives, such as smart home, smart medical care, smart agriculture, smart transportation and smart cities. A large number of IoT devices are connected to the online cloud, and the explosive growth of device data information. The traditional cloud centralized processing model will not be able to meet the needs of rapid transmission and processing of large amounts of data. Therefore, realizing the local communication management function of Internet of Things device access; how to solve the problems of network instability and high delay that restrict user experience through the MQTT communication protocol with low overhead and low bandwidth occupation has become an urgent problem for technician...
