How to get the parameters in the QR code with parameters?

Question

Hello everyone, I am using PHP to create a QR code with parameters, but I want to get the detailed information (action_info) of the parameters in the QR code. How can I achieve this? Thank you~

Answer 1

The process of generating a QR code with parameters has two steps. First, we need to create a ticket for the QR code, and then use the ticket to the specified URL to exchange for the QR code.

　Every time you create a QR code ticket, you need to provide a parameter (scene_id) set by the developer. The process of creating a QR code ticket for temporary QR codes and permanent QR codes is introduced respectively.
