Telegram Bot Webhook Messages

本篇将电报群机器人，通过 Webhook 回调接口，返回的消息体，收集和展示出来。 便于对电报群消息的解析和监控处理。

Webhook 回调的消息处理和存储注意事项

1. 消息的内容，可能包含表情，视频，图片等；用户的昵称也会有表情
如果数据库采用 MySQL，需要将编码集改为 utf8mb4，并且，应用层的连接 encoding 也需要改为 utf8mb4 字符集。
MySQL 支持表情字符的保存详细信息请看之前的博客： Aliyun RDS Change MySQL Charset From utf8 To utf8mb4

2. 关于用户的个人信息模块，一开始没有返回 username，运行后期才出现

Webhook 回调的消息示例

// 系统上线后期，发现，用户结构内，包含 username
