java-给微信推送消息 利用企业微信

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）
