Abstract

The invention relates to a message processing method and device, an Internet of Things system and a storage medium. The message processing method comprises the following steps: when a published message sent by a published client is received, obtaining a user role of the published client; if the publishing client is confirmed to have the publishing authority based on the user role, detecting whether the theme of the published message conforms to a preset format or not; wherein the preset format comprises theme containing identification information; and when the detection result is yes, pushingthe published message. According to the invention, the security of the Internet of Things system can be improved, and the MQTT message is ensured not to be maliciously stolen and forged.

Description

Technical field [0001] This application relates to the field of Internet of Things technology, and in particular to a message processing method, device, Internet of Things system and storage medium. Background technique [0002] The MQTT (Message Queuing Telemetry Transport) protocol is a widespread protocol in the Internet of Things (IOT) system. It is a topic-based message publishing / subscription protocol. The client can publish messages to a specified topic. If other clients care about the message of the topic, they can subscribe to the message of the topic. When a message is published on the topic, the message Will be automatically pushed to subscribers. [0003] The simple usage of MQTT protocol can be as figure 1 Shown: the message subscriber Client C first subscribes to the specified topic of the MQTT service, for example, the topic of / report / data is subscribed here. Message publishers Client A and Client B can publish messages to the / report / data topic at any time, and t...
