The invention provides a role-based front-rear-end separation architecture access control system and method, and the system comprises an authority role association module, a route authority role registration module, a route system, an access control module, a route monitoring module, an identity authentication module and a data access module. The authority role association module is respectively connected with the route authority role registration module and the data access module, and the route authority role registration module is connected with the route system. The identity authenticationmodule is connected with the data access module and the route monitoring module, and the route monitoring module is connected with the route system and the access control module. The access control module is respectively connected with the data access module and the route system. The invention mainly solves the problem of the access control of a front-end restricted resource in the front-rear-endseparation architecture, enhances the front-end authority control capability, limits the improper interface request, and improves the user interaction logic.
