Cloudflare Worker自动检测并添加serv00/CT8的Cron

XJFKKK2024-11-142025-01-22

由于Serv00会定期清理cron任务，使得部署的服务失效，这是最令人头疼的。

本脚本通过自动登录Serv00/CT8来定期监控cron任务，若不存在则添加并推送电报通知。（存在的话不会添加cron且不会推送消息，避免消息爆炸）

效果图：

1.在cloudflare创建worker

登录以下网址：
https://www.cloudflare.com

创建worker

将下面代码复制粘贴进worker

      "username": "user2",
      "password": "password2",
      "panelnum": "2",
      "type": "serv00",
       "cronCommands": [
        "/usr/home/serv00name"
      ]
    },
    {
      "username": "user3",
      "password": "password3",
      "type": "ct8",
      "cronCommands": [
        "/usr/home/serv00name",
        "你的脚本",
        "python /usr/home/serv00name/domains/backup.py"
      ]
    }
  ]
}

cronCommands这部分是你想要添加的cron任务，可以是路径，也可以是程序运行的命令

TELEGRAM_JSON

{
  "telegramBotToken": "YOUR_BOT_TOKEN",
  "telegramBotUserId": "YOUR_USER_ID"
}

PASSWORD

1	你访问worker面板的密码

3.添加Cron

为了频繁登录执行脚本，建议各位佬友把时间填4-12h为宜

4.创建一个KV变量

创建一个名为CRON_RESULTS的KV变量

回到刚才创建的worker界面绑定KV

5.绑定自定义域名

点击运行按钮脚本就开始启动了

这个面板会记录你最后一次执行的命令结果，包括你手动执行或者是设置的定时Cron。

当你部署在serv00的网站不能访问时，通过访问worker，点击一下运行脚本就能马上执行任务了，避免了频繁的使用cron启动脚本登录网站执行命令

电报只有当cron被干掉重新建立时才会通知（运行就消息推送会消息爆炸），这个可视化面板会记录输出的最后一次运行状态算是弥补了这部分
