企业微信官方接口：
应用支持推送文本、图片、视频、文件、图文等类型。
请求方式：POST（HTTPS）
请求地址： https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=ACCESS_TOKEN
大概思路：
1. 封装调用企业微信函数 SE37 ：ZWECHAT_SEND_MESSAGE_MSGTYPE
注：
a. I_MSGTYPE 参数值 作为动态值新增到表结构，构造企业微信API body
b. I_MESSAGE 参数值 为json格式的消息内容
2.程序调用 ZWECHAT_SEND_MESSAGE_MSGTYPE，传入处理过的 I_MESSAGE
代码实现：
1. SE37 ：ZWECHAT_SEND_MESSAGE_MSGTYPE
1 FUNCTION zwechat_send_message_msgtype.
