使用selenium完成健康打卡
一年前,写了selenium打卡的代码.一年来也有不断地更新版本,添加邮件通知功能,http get请求进行腾讯文档标注(后来腾讯文档改版,隐藏了接口).以及用post登入验证打卡是否成功.到今天,算是完成了2.0版本的,现在整个程序觉得还蛮满意的(强迫症的满足).

---

一、为什么想改?

1. 强迫症

虽然selenium已经很方便的,但我还是觉得不够优雅,使用浏览器+driver的方式太臃肿了,相比于图形操作的方式,我更喜欢命令行的方式.

2. 不方便

有不少同学会想找我要代码,但是我想介绍的时候,即使是计算机专业的同学介绍还是蛮麻烦的,毕竟需要配置driver环境变量,还要下驱动.非计算机专业的同学大概率没得python环境就更难介绍了.(后续查好像selenium也可以打包,不确定没装驱动可不可以)

3. 不稳定

其实用selenium我个人觉得不稳定因素贼多,老是会出错,所以我会在一年里用了很多方法处理,比如邮件确定,try catch捕获异常,用post登入确保一定登上.这一系列的操作,让程序又臃肿起来了.
第二个不稳定因素是webdriver的问题,Chrome老自动更新.driver也要更新挺烦的

二、过程

1. 登入系统

抓包登入接口.此处有一个问题需要处理:
登入的密码其实与我们的密码不一致,是经过算法加密的.所以想要直接使用这个接口的话,需要对代码进行处理.我找了好哥们儿帮我找到了加密方式,解决了这个问题.其实也有替代方案,要哪个账号打卡就登入一下抓包就能拿到了,不过不优雅.
这个接口能得到的响应:

这里的响应会有msg,用于判断是否打卡
jnuid后续post的重要凭证

2.获取历史信息

拿到jnuid以后就可以通过这个另外一个接口获取信息

3.用历史信息构造请求体数据,post

写的时候发现,暴露的东西有点点多,我还是把具体步骤隐藏起来吧,下面的代码是可以用的,但是需要自己抓包接口.另外我还发现了一个问题,觉得系统不是很安全.我还是不要暴露了

然后发现打卡并没有用session.如果有的话其实更方便,用session.request()

---

三、使用(不发邮件版)

1.我将代码打包成exe文件(可直接在Windows10运行).这里我修改了代码为本地版本的,不再发邮件而是使用log.txt的形式进行记录.使用的打包工具是pyinstaller我这里打包的是带命令行界面版的
2.以account.txt作为账户输入.格式为账户 (空格) 密码 (空格) 姓名
如果多个账户换行即可.示例:

20xxxxx xxxxx 张三
20xxxxx xxxxx 李四

相应的打卡记录会显示在同一目录下的log.txt中
3. Windows定时任务定时执行代码.(可以看后面的参考资料)

四、代码(未阉割版)

以下为批量打卡程序

import post_daka_success
from email.mime.text import MIMEText
import smtplib
account = [['账号','密码','姓名','邮箱']]

msg_from = ''  # 发送方邮箱
passwd = ''  # 填入发送方邮箱的授权码
msg_to = ['']  # 收件人邮箱
subject = "打卡邮件"  # 主题
content = ""

for acc in account:
    obj = post_daka_success.daka(acc[0],acc[1])
    obj.run()
    if obj.check():
        content += "程序已经为"+acc[2]+"打卡\n"
    else:
        content += acc[2]+"未打卡\n"


s = smtplib.SMTP_SSL("smtp.qq.com", 465)
msg = MIMEText(content)
msg['Subject'] = subject
msg['From'] = msg_from
msg['To'] = account[0][3]
s.login(msg_from, passwd)
s.sendmail(msg_from, account[0][3], msg.as_string())

以下为打卡用的程序
