Version updating method of server interface and calling method of server interface

The invention relates to a version updating method and device of a server interface and a server interface calling method and device. The version updating method comprises the steps: acquiring a to-be-updated interface version; comparing the to-be-updated interface version with a preset interface version, and determining a first interface different from the preset interface version in the to-be-updated interface version; and generating an updated interface version, wherein the updated interface version includes the first interface. Through the method and the device, the application is simple,according to the interface updating method and device, the problem that in the prior art, when a certain interface is updated each time, the interfaces, with the same interface identifiers as the interfaces needing to be updated, in all old interface versions need to be updated into new interfaces, so the workload of interface code modification and testing is increased is solved, and the workloadof interface version maint
