本篇仅提供思路，代码不能直接拿来用哦
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
