基于 dash + feffery-antd-components 单文件实现定时任务调度平台
实现效果
列表展示定时任务
支持搜索, 添加, 启用. 停用. 编辑, 和删除功能
新增/编辑/删除定时任务
支持 周期/日期/corn 三种调度模式
支持 python/shell/api 三种任务类型
删除进行二次确认后即可删除
触发记录查看
支持详情查看, 以及一些便捷 搜索/筛选/分页功能
日志详情
可查看任务的执行结果, 展示原始执行脚本, 和标准以及异常输出

安装依赖后 解除 td.reset_db() 行进行初始化数据库创建
数据库创建完成后, 再次启动服务, 则直接访问 127.0.0.1:5080 即可进行所有功能
相关说明
1. 仅支持了本地化执行, 不支持远程作业调度
2. 若想实现远程调度则需要在开发新页面和建模表实现ssh访问凭证的curd
3. 定时任务基于 apscheduler, 相关的详细使用文档可参考 这个博客里面写的很详细
4. 相当于实现了一个前后端不分离的实现作业调度虽小但全的麻雀demo, 简单便捷, 堪堪可用
5. 还是要吐槽一句前端写起来属实蛋疼,,,,,, 真特么是每个交互顺序都要一点一点扣出来,,,,麻
