Python实现今日校园自动签到

本篇仅提供思路，代码不能直接运行哦

每天早上8点都要打开今日校园APP签到，填表。。就不能让人好好睡个觉啊！！为了解决这个头疼的问题，想到了用python中的Request库进行发送请求

鲁迅说： 人类越来越懒、发明越来越多!创造来源于我们的生活啊!

话不多说，开始造车！

国际惯例！打开Burp抓抓抓 在点击提交按钮后，捕获到了三个POST请求 让我们来逐条分析

1. 第一个POST的作用： 判断"wid":“422"任务是否存在，存在返回"message”:“SUCCESS” ，不存在则返回"message":null　　【这里提一下”422“的含义，简单的说就是老师发布这个表给同学们填，这个任务的编号是422。】

2. 第二个POST的作用： 查询"wid":"422"任务的基本信息，为啥这里说是基本信息，因为只返回了这个任务创建者是谁，什么时候发布的等等，并没有返回这条任务的详细内容

3. 第三个POST的作用： 聪明的小伙伴们应该已经猜到了，第三个POST请求返回的就是 “message”:“SUCCESS” 以及"wid":”422“这个任务的详细信息， 内容是老师让我们填的一些个人状况，家庭住址什么的

数据包分析完了，很明显，重点在第三条，第三条数据的Body中的"wid":“422"是关键，我们只要找到这个"wid”:"num"中的num 再构造Request请求就OK了！

怎么找呢，想到了一种穷举的思路，用指定范围的数值来构造 422~999的POST请求 ，再传到Body里 发送Request请求 完成提交

在构造Body时发现了个更好玩的地方，如果把422改成423 就会返回”您无需填写该信息收集，请勿代填“ 说明这个任务不是我们学院老师发布的，也就是说如果是其他学院发布的任务 我想提交都提交不了！！ 这里是重点 我们可以利用系统这个判断机制进行不断的发包 如果返回不是SUCCESS就是没提交成功（没提交成功不代表没发包成功），则继续构造包 发送包，如果返回SUCCESS那就皆大欢喜 成功提交了，咱们的最终目的就完成了

下面看代码， 可不要被这一堆代码给吓到哦，head,body部分都是复制粘贴的Burp抓的数据包

最后给代码加上了休眠

为了让程序间接性的向服务器发送数据包，我们用到了Python中的time库 ，使用sleep()函数让程序运行一会歇一会，这一路上走走停停 顺着少年漂流的痕迹 ~

最终部署在服务器上的运行效果展示：
