Authority control method and device and storage medium

Embodiments of the invention disclose an authority control method and apparatus, and a storage medium. The method comprises the steps of determining a constraint item set of an authority of a target entity; obtaining the attribute and configuration information of each constraint item in the constraint item set; according to the attribute and configuration information of each constraint item in the constraint item set, determining a corresponding model module in the permission model of the target entity and an association relationship corresponding to the model module; constructing each model module by using the configuration information of each constraint item, and associating the constructed model modules according to an association relationship to obtain a target permission model; and generating the permission of the target entity based on the target permission model to control the target entity to access a resource corresponding to the permission. According to the method, the expandability and usability of
