The invention provides a two-dimensional code display method, which comprises the following steps that: after an application program is started, if a login cache exists locally, entering an offline process and simultaneously carrying out an online request process, and when an online request is carried out, a terminal interacts with a server; the offline line process comprises the following steps:querying local cache data and judging whether first data information of a local cache meets requirements or not; if the locally cached first data information meets the requirement, signing by adoptinga private key, assembling cached data and then displaying a two-dimensional code; and if the first data information of the local cache does not meet the requirement, obtaining the related data information from the server, refreshing the local cache, and returning to continue to execute the step of judging whether the first data information of the local cache meets the requirement or not. According to the invention, the two-dimensional code display speed is improved and the safety is ensured as much as possible.
Description
technical field [0001] The present invention relates to the technical field of two-dimensional codes, in particular to a two-dimensional code display method, device, terminal and computer-readable storage medium. Background technique [0002] It should be noted that the contents recorded in this section do not represent all prior art. [0003] When the terminal device displays the QR code, it needs to continuously interact with the server to confirm whether the information meets the requirements. The interaction process takes a lot of time, especially in the field of transportation. The network environment is complex, especially during peak hours. Code display affects experience. Contents of the invention [0004] In view of this, in order to solve one of the technical problems in the related art to a certain extent, it is necessary to provide a two-dimensional code display method, device, terminal and computer-readable storage medium, which is conducive to improving the ...
