gdut_erke's Introduction

声明

只是发现了一个小bug（但是学校好像并没有想要修复的样子） 要成功签到和签退的前提是成功报名该活动

已经打包成了exe文件，可在windows下运行，在目录处生成二维码，源文件是Qrcode.py

原理

二维码本质是网址，观察erke的链接可以发现

1713274015472其实是2024-04-16 21:26:55北京时间（ms）的时间戳——是不是跟上面ts后面的数字很像，所以结论就是ts后面的数字就是签到和签退过期的时间，token后面的和ts类似。

一次使用

token生成的链接只能被唯一识别并在服务端产生一对一标记

多次使用

利用ts来实现多人扫码
