本篇僅提供思路，代碼不能直接拿來用哦
每天早上8點都要打開今日校園APP簽到，填表。。就不能讓人好好睡個覺啊！！為了解決這個頭疼的問題，想到了用python中的Request庫進行發送請求
魯迅說：人類越來越懶、發明越來越多!創造來源於我們的生活啊!
話不多說，開始造車！
國際慣例！打開Burp抓抓抓 在點擊提交按鈕后，捕獲到了三個POST請求 讓我們來逐條分析
1. 第一個POST的作用： 判斷"wid":"422"任務是否存在，存在返回"message":"SUCCESS" ，不存在則返回"message":null 【這里提一下”422“的含義，簡單的說就是老師發布這個表給同學們填，這個任務的編號是422。】
2. 第二個POST的作用： 查詢"wid":"422"任務的基本信息，為啥這里說是基本信息，因為只返回了這個任務創建者是誰，什么時候發布的等等，並沒有返回這條任務的詳細內容
3. 第三個POST的作用： 聰明的小伙伴們應該已經猜到了，第三個POST請求返回的就是 "message":"SUCCESS" 以及"wid":”422“這個任務的詳細信息， 內容是老師讓我們填的一些個人狀況，家庭住址什么的
數據包分析完了，很明顯，重點在第三條，第三條數據的Body中的"wid":"422"是關鍵，我們只要找到這個"wid":"num"中的num 再構造Request請求就OK了！
怎么找呢，想到了一種窮舉的思路，用指定范圍的數值來構造 422~999的POST請求 ，再傳到Body里 發送Request請求 完成提交
在構造Body時發現了個更好玩的地方，如果把422改成423 就會返回”您無需填寫該信息收集，請勿代填“ 說明這個任務不是我們學院老師發布的，也就是說如果是其他學院發布的任務 我想提交都提交不了！！ 這里是重點 我們可以利用系統這個判斷機制進行不斷的發包 如果返回不是SUCCESS就是沒提交成功（沒提交成功不代表沒發包成功），則繼續構造包 發送包，如果返回SUCCESS那就皆大歡喜 成功提交了，咱們的最終目的就完成了
下面看代碼，可不要被這一堆代碼給嚇到哦，head,body部分都是復制粘貼的Burp抓的數據包

最后給代碼加上了休眠
最終部署在服務器上的運行效果展示：
完
