Interface simulation method and device for automatically providing interface service

The invention provides an interface simulation method for automatically providing interface service, which comprises the following steps of prefabricating interface data, making an interface description file and an interface data return file for each interface, making the interface data return file according to the interface description file, wherein the interface description file is used for describing the interface data and standardized manufacturing is realized according to the interface description file, the interface data return file is interface data returned after the interface is requested to be served, and is manufactured according to an interface data return file specification; storing the manufactured interface description file and interface data return file into an interface data memory; and carrying out interface request processing: receiving an interface service request sent by the interface data request end, reading the interface description file and the interface data return file from the inte
