Interface configuration file generation method and device

The invention discloses an interface configuration file generation method and device, and the method comprises the steps: generating an interface document of a to-be-interface reconstruction system according to an interface configuration file of the to-be-interface reconstruction system; wherein the interface configuration file comprises an xml file carrying field information corresponding to different message field labels; obtaining an interface document of the system after interface reconstruction; summarizing and combining the interface documents of the system to be subjected to interface reconstruction and the system subjected to interface reconstruction to generate a summarized interface document; wherein the summarized interface document contains field information corresponding to alabel in an interface document of a system to be subjected to interface reconstruction and a system after interface reconstruction under each message field label; and performing field information analysis on the summarized in
