自从学校换了强智的教务系统后，学校的app的查课表功能基本就报废了，记不住课表的我无奈自己动手。
功能实现：如果当天有课，在当天早上6点30以短信的形式自动发送课表至手机
首先我想的是利用模拟登陆然后直接获取课表
输入一些错误信息，点击登陆，得到一个请求
其中的flag参数是重要线索，顺着这个参数找到对应的js
此时可以发现整个加密的流程
通过向/Logon.do?method=logon&flag=sess发送请求获得一个dataStr
再将dataStr切片，分成scode与sxh
code = 用户名 + ‘%%%’ +密码
再通过for循环加密，得到encoded (登录的请求参数之一)
同时对验证码进行识别（我用的是pytesseract + PIL）
最后将userAccount(用户名）、userPassword（密码）、RANDOMCODE（验证码）、encoded作为参数向http://logon.do/?method=logon发起请求，即可完成模拟登录。
但由于pytesseract的处理能力实在有限，识图率太低了（灰度处理、二值化、降噪后处理成功率还不到一半）
然后我选择了另一种方法
强智有一个小程序叫智校园助手，利用HttpCanary可以获取强智的接口，然后又在git上找到了教务系统api的python封装
嘻嘻嘻，于是事情变得简单了起来

最后只需要在利用crontab在服务器上设置一个定时任务每天6点30执行一次就可以啦
