使用阿里云云函数进行bugku签到

参考文档：

dota_st师傅的博客

阿里云fc文档

准备工作

• 阿里云账号（支付宝账号，淘宝账号）
• GitHub账号(用于登录bugku)

  抓取自己GitHub的cookie备用(user_session的值)

• bugku账号(绑定GitHub账号)
• 签到脚本(基本使用dota_st这位师傅博客中的脚本，进行了一些小修改)

  index.py 云函数服务默认调用的文件名，不要修改

  main()

  配置.txt，记得把对应的参数加进去

  user=你的用户名# server_key=填写你的server酱# git_cookie=填写抓包获得的githubcookie#
******author:dota_st******

  • 然后去注册一下server酱，绑定你的微信。然后通过调用server酱，把打卡结果发送到微信上

云函数部署

创建云函数

阿里云云函数网址

首次开通不收费，跟随指导直接默认开通就行

进入管理控制台 -> 选择函数 -> 创建函数 -> 选择事件函数 -> 填写函数名称，运行环境选择python，通过文件或压缩包上传代码 ->点击创建

配置运行环境

因为脚本需要用到一些外部库，因此需要下载，点击函数名进入函数，往下拉到在线编辑器界面，进入终端

进入终端后依次输入命令：

这三个命令的意思是更新pip，下载retrying库和bs4库脚本所在目录，库的具体作用自行百度

完成后点击部署代码，点击测试函数，可以看到脚本执行后的回显（我已经签过到了）

设置定时任务

往上找到配置点击后在触发器功能里创建触发器，选择定时触发器 ->输入定时器名称 自定义cron表达式 CRON_TZ=Asia/Shanghai 0 0 7 * * *（每天7点执行，可以更改数字7改变时间）点击确定。至此全部完成
