Request response method, device and system, server and storage medium

The embodiment of the invention discloses a request response method, device and system, a server and a storage medium, and the method is applied to a gateway server, and comprises the steps: receiving a user request sent by a client; determining target verification configuration information corresponding to a target API interface according to target API interface information in the user request; according to the target verification configuration information, detecting whether the user request meets a target verification condition; and if the user request meets the target verification condition, sending the user request to a target algorithm model of a background server by calling a target API interface of the background server, so that the target algorithm model performs response processing on the user request. Through the technical scheme of the embodiment of the invention, unified verification of user requests can be realized, and the non-business logic codes and the business logic codes related to the algo
