云函数自动签到视频教程bilibili在线播放
使用腾讯云函数，设置语言python3.6，模板空白函数
将index.py改成zjy.py，执行方法改成zjy.auto_signin
将下面代码的内容复制到云函数的zjy.py，修改网页中zjy.py的用户名，密码
设置内存64MB，超时4s
设置环境变量TZ=Asia/Shanghai即可
添加触发方式，使用自定义触发

注意: 运行次数过多将产生费用参考云函数定价
免费额度：资源使用量40万GBs 调用次数100 万次
计费定价(超出免费额度部分)：资源使用量0.00011108元/GBs 调用次数0.0133元/万次 外网出流量0.8元/GB
资源使用量 = (内存/1024) × (运行时间(毫秒)/1000)
因账单明细费用（计费）最多支持8位小数，而账户支付金额（扣费）最多支持2位小数，故在高精度计费和低精度扣费之间存在精度差异，系统会按高精度计费与按低精度扣费之间的差额进行自动精度差异调整。
以下面的实时签到为例
资源使用量 = (64/1024) × (700/1000) = 0.04375 GBs
调用次数= 20 × (19-7+1) x 60 x (5/60) = 18720次
资源使用量和调用次数都没有超出免费额度，所以只需要支付外网流量
每次调用的外网流量平均应该5K不到，实测定时签到在月度计费精度差异下可以免去费用(单个实时签到应该也行)

以下是触发参考，更多自定义触发参考cron文档
定时签到参考
9点50左右有一次签到(星期二到星期五的上午9点45-54的每五秒钟执行一次

*/5 45-54 9 * * TUE-FRI * 

13点40左右有一次签到(星期一和星期三的下午1点35-44的每五秒钟执行一次)

*/5 35-44 13 * * MON,WED * 

实时签到参考(频率高时，返回值是Unicode编码，Unicode转中文)
上午7点到19点不定时会有签到(星期一到星期五的上午7点到19点的每五秒执行一次)

*/5 * 7-19 * * MON-FRI * 

支持常规、手势、二维码签到
代码如下,开启邮箱通知，修改mailConfig中Eanbled的值False为True，按照提示配置SMTP,开启邮箱记得调整超时。开启server酱，修改serverChan中Eanbled的值False为True，并配置SCKEY。
