Software service access control method and device

The invention provides a software service access control method and device, and aims to solve the problems that different software versions need to be deployed independently and unified maintenance and management of software are not facilitated because the same software version cannot be kept when a current client customizes logic. A software module is divided into a standard service module and acustomized service module, the standard service module is used for realizing a general service function, and the customized service module is used for realizing a customized service function; for different users, when the users initiate service access requests, different service entries are distributed based on routing, a standard service module is accessed normally, a customized user enters a customized service module, corresponding service functions are completed, standardized or customized services of clients are realized, and independent software versions do not need to be formed for customized service clients res
