Generation and processing method and system of universal two-dimensional code string

Abstract

The invention belongs to the technical field of two-dimensional codes, and provides a method and a system for generating and processing a universal two-dimensional code string. The universal two-dimensional code string generation method comprises the following steps: searching whether an unexpired user certificate is stored in a user side or not; splicing a preset routing segment, preset service scene information, a preset unique identifier of a user side, preset first expiration time, the user credential and a user credential signature corresponding to the user credential under the condition that the user credential which is not expired exists to obtain a basic code string; splicing the basic code string and the code string signature to obtain a two-dimensional code string; the code string signature is signature information obtained by using a preset user private key to sign the basic code string. Therefore, the two-dimensional code can be generated under the condition of a weak network or no network, the use scene of the code used by the user is expanded, and the experience of using the two-dimensional code by the user is improved. And meanwhile, the operation pressure of the code server is reduced, and the code server can operate more stably.
