Wechat generates a temporary QR code with parameters. The user scanned it once, and the temporary parameters were the same on the second scan. - Codes Helper - Programming Question Answer

Wechat generates a temporary QR code with parameters. The user scanned it once, and the temporary parameters were the same on the second scan.

Today, when testing, we found that after generating the QR code for the first time, the user scanned the code for a temporary parameter, and the same user created a new parameter the second time, but Wechat returned the temporary parameter for the first time, making it impossible to judge the user"s behavior based on the temporary parameter after the second time. Could you tell me how to solve this?
