示例脚本中有很多 print 打印的输出，主要是为了方便调试使用。如果开启，可通过 n9e 的日志进行查看，日志调试在 INFO.log，报错状态在 ERROR.log，过滤关键词 event_script_notify。

更新说明

从 v8.0.0-beta7 版本开始，抽象了通知规则的概念，这个用户自定义联系方式的功能，已经基本用不到了。比如各种机器人 token（企微机器人Key、钉钉机器人Token等），都不应该放到用户联系方式里。

那这个用户联系方式是否可以下线呢？也不是。还有一些个别场景有需求。比如企微除了机器人的通知方式，还有企微应用的通知方式，企微应用通知的话，需要拿到用户的企微账号（一般公司的企微账号都是和员工邮箱前缀保持一致），这里的企微账号信息，就适合放到用户联系方式里。

即：只有真正和用户个人相关的信息，才应该放到用户联系方式里。
