Cloud data reading method and device

Abstract

The embodiment of the invention provides a cloud data reading method and device, and the method comprises the steps: obtaining a data reading request initiated by a target user, the data reading request comprising the user information of the target user, and target data expected to be read by the target user; authenticating the identity of the target user according to the user information of the target user; if it is judged that the identity authentication of the target user is passed, obtaining target data from topics corresponding to target users in the server, and when each user applies forthe cloud access service at the server, allocating a corresponding topic, the topic being a logic storage unit divided by the server according to data sources of different users, and storing the datasources of the same user in the same topic. According to the cloud data reading method and device provided by the embodiment of the invention, the authentication mechanism is adopted to perform safety control on the distributed message system, so that the real-time performance and the high efficiency of data reading are ensured, and the safety of data is ensured.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a cloud data reading method and device. Background technique [0002] Equipment data collection and analysis are two essential services provided by the industrial Internet platform for industrial enterprises, but there are also some enterprises that have independent research and development capabilities. They know their business better than the platform, and hope to only use the equipment access and Data collection service, complete data analysis by yourself. This requires a reasonable way to obtain device data from the industrial Internet platform side, so that the industrial Internet platform can provide users with efficient cloud access services. [0003] In the prior art, industrial Internet platforms provide users with RESTful API query methods to obtain device data stored on the platform.

Problems solved by technology

[0003] In the prior art, industrial Internet platforms provide users with RESTful API query methods to obtain device data stored on the platform. However, RESTful API queries are based on HTTP short connections, which have problems such as multiple calls and poor real-time performance. API calls will also greatly increase the load on the industrial Internet platform, which cannot meet the urgent needs of users for high-speed, real-time subscription data to the industrial Internet platform
