分析
首先,要想使用浏览器登陆易班,我们需要一个特定的请求头.登陆时,易班中的js代码会对window.navigator进行检查设备是否为手机.登录过程通过简单的发送请求难以获取到Cookie,因为这其中有很多JS代码需要运行.所以应该使用无头浏览器获取到Cookie,之后在使用Cookie调用易班的接口.无头浏览器,笔者使用Python中的selenium,发送请求,笔者使用requests.
使用Chrome访问易班校本化
设置请求头用户代理字符串设置为Mozilla/5.0 (iPhone; CPU iPhone OS 14_7_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 yiban_iOS/5.02. 使用Chrome移动端体调试功能

在main函数中从users.json读取账号信息
非常简单，新建个对象，调用一下函数就可以了
def do_task():with open("src/users.json", 'r', encoding='utf8') as f:users = json.load(f)infos = users.get("userInfos")for user in infos:print("当前用户:", user.get("name"))yiban = YiBanHelper(password=user.get("password"), username=user.get("username"), show_cookie=True)person_info = user.get("dataJson")yiban.submit_task(info=person_info, auto_wf_id=True)# Press the green button in the gutter to run the script.if __name__ == '__main__':do_task()
远程服务器运行
编写shell,将每次的输出以日期命名放在一个文件夹中.在Linux中创建定时任务,在任务开始的时候自动运行,然后就彻底告别易班了!!
cd 相关目录current_date=`date '+%m-%d'`current_time=`date`result=`python3 "main.py"`mkdir -p logecho -e "${current_time}\n $result \n" >> "log/${current_date}.log"
本地自动运行
当然，如果你是Mac或者Linux用户都是可以创建自动化任务的,在终端中输入crontab -e来编辑定时任务。
如果你是windows用户的话，win+R，输入taskschd.msc可以创建windows的自动化任务
备注:本方法在NJNU已经失效，因为对发送的数据进行了加密。但是这只是一个日报功能，其他的晚点签到仍然可以使用类似的方法实现全自动签到。
