jsoup登录日志平台后调企业微信机器人自动发送错误日志告警

本文主要是介绍jsoup登录日志平台后调企业微信机器人自动发送错误日志告警，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、需求：错误日志Top10告警发送

二、需求分解

jsoup实现登录，获取到cookie和token等用户鉴权信息
获取接口相应的key值
调用日志平台错误日志Top榜接口，查询到结果集
调用企业微信机器人发送消息接口
加上定时任务，可以实现定时发送错误日志告警的功能

定时任务高度设置1小时（根据实际需要）执行一次，可以实现自动巡检错误日志的功能。以便及时发现生产问题

jsoup是java的爬虫框架，可以爬取网页数据，这里没有重点使用，只是做了个登录功能。后续可以专门它写一份爬虫的程序。。
