java-给微信推送消息
目的：给关注用户推送消息
场景：自动化测试,运维监控，接口访问等报错预警。例如线上接口报错，发送提醒消息
准备工作：
1:注册企业号（为什么不用公众号呢？）
企业号注册
2:常用参数介绍：
1:CORPID企业号唯一标志符号。
位置：点击首页企业名称，企业资料中有key：CorpID
2:CORPSECRET：
需要创建单独等应用。具体步骤，按照提示一步一步来即可。需关注2个参数
Secret和AgentId（用于区分给哪个应用推送消息）
3:发送消息准备工作：
关注自己的企业号。（需要先绑定手机号）
4:纪录下需要发送消息的通讯录Id
用于给指定用户推送消息
5:代码结构
1:获取token
2:发送消息
6源码：（在你执行下面代码的时候，AgentId改为你自己的）
