The invention relates to an app interface replacement prevention method and a
server. The method comprises the steps that an interface request sent by a sender is received; sender
verification information in the interface request is acquired, and whether or not the sender
verification information meets the preset
verification requirement is verified; and if yes, a
processing affair of the interface request is executed, a response message is returned, and otherwise, the interface request is not processed, and an
error message is returned. According to the app interface replacement prevention method and the
server, the sender verification information in the interface request is acquired, and whether or not the sender verification information is reasonable is verified; when the sender verification information is reasonable, it indicates that the interface request is reasonable, the
processing affair of the interface request is executed, and then the response message is returned to the sender to inform the sender that operation succeeds; if the sender verification information is unreasonable, the interface request is considered to be wrong and not processed, and the
error message is sent to the sender; and accordingly, the condition that due to the fact that the
server receives the same interface request multiple times, data of a
database is disorder, and even the server is down isavoided.
