Title: TWO-DIMENSIONAL CODE INFORMATION QUERY METHOD, SERVER, CLIENT, AND SYSTEM
Abstract:
Provided are a two-dimensional code information query method, server, client, and system, relating to the technical field of image recognition; the main objective of the invention is to solve the problem in the prior art of it being impossible to identify, across clients, user identity information in a two-dimensional code; by means of one two-dimensional code containing user identity information of a plurality of clients, "one code, many uses" is achieved, that is, cross-client identification of user identity information in a two-dimensional code is accomplished. The method comprises: receiving a two-dimensional code query request sent by a first client (101), the two-dimensional code query request containing a first two-dimensional code; according to the first two-dimensional code, querying another two-dimensional code bound to the first two-dimensional code (102); returning the queried other two-dimensional code to the first client so that the first client displays the returned other two-dimensional code (103); the first two-dimensional code being bound to the other two-dimensional code comprising: receiving a two-dimensional code binding request sent by a second client; establishing a binding relationship between the first two-dimensional code and at least one other two-dimensional code.
