如何制作一个企业微信机器人

最近老是看到别人在企业微信群里搞个机器人，每天定时发送消息。闲着蛋疼就了解了一下。

1、创建一个企业微信机器人你会发现它其实就是一个接口。

以及有它的配置说明，发送不同格式或类型的消息。

2、编辑脚本

导入依赖的jar包

    org.apache.httpcomponents
    httpclient
    4.5.13


    org.apache.httpcomponents
    httpmime
    4.5.13


    org.apache.httpcomponents
    httpcore
    4.4.15

 脚本

 3、在windows上挂个定时任务
