Problems solved by technology

At present, the interaction between IoT devices is usually realized by subscribing to each other's path (Topic) and then sending messages to each other's path. However, this kind of cross-device path authorization is difficult to manage, and it is easy to cause the problem of unauthorized use.

Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The embodiment of the present application may be applied to MQTT (Message Queuing Telemetry Transport, message queue telemetry transmission) technology. In the existing MQTT, cross-device Topic authorization is required. After authorization, the device side needs to subscribe to receive the corresponding Topic message, which leads to confusion in Topic authority management, and the problem of illegal unauthorized use is prone to occur. However, the embodiment of the present application does not require cross-device authorization, but establishes a routing relationship between a source path and at least one destination path, which facilitates authority management and prevents unauthorized use.

Abstract

The embodiment of the invention provides an inter-device communication method and device, equipment and a storage medium, and aims to solve the communication problem of cross-device Topic authorization. The inter-device communication method comprises the following steps: establishing a routing relationship between a source path and at least one destination path; querying the routing relationship according to the received message, and determining at least one destination path and the number of routes; selecting a message sending mode according to the routing number; and sending the message according to the message sending mode. According to the inter-device communication method, communication is carried out without a cross-device path authorization mode, and the routing relationship can beinquired for the received message, so that the message is sent more flexibly, and the problem of unauthorized use is avoided.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an inter-device communication method, an inter-device communication device, a server, a routing gateway, and a storage medium. Background technique [0002] The Internet of Things (IoT) is an Internet where things are connected. With the rise of the Internet of Things, IoT devices are becoming more and more diverse. [0003] IoT devices need to be connected to the Internet to realize interactive communication with other IoT devices and with servers in the cloud for message delivery and device control. At present, the interaction between IoT devices is usually realized by subscribing to each other's Topic and then sending messages to each other's Topic. However, this kind of cross-device path authorization is difficult to manage, and it is easy to cause the problem of unauthorized use. Contents of the invention [0004] The embodiment of the present application ...
