-# 希望的demo实现效果：
-# 1. 从stdin拿到告警信息之后，格式化为一个有缩进的json写入一个临时文件
-# 2. 文件路径和名字是.alerts/${timestamp}_${ruleid}
-# 3. 调用SMTP服务器发送告警，微信、钉钉、飞书、slack、jira、短信、电话等等留给社区实现

-# 脚本二开指南
-# 1. 可以根据下面的 TEST_ALERT_JSON 中的结构修改脚本发送逻辑，定制化告警格式见tpl下的模块文件
-# 2. 每个告警会以json文件的格式存储在 LOCAL_EVENT_FILE_DIR 下面，文件名为 filename = '%d_%d_%d' % (rule_id, event_id, trigger_time)
-# 3. 告警通道需要自行定义Send类中的send_xxx的方法，反射调用：举例 event.notify_channels = [邮件] 则需要在NOTIFY_CHANNEL_DICT配置 邮件=email，在Send类中实现 send_email 方法
-# 4. im发群信息，比如钉钉发群信息需要群的webhook机器人 token，这个信息可以在user的contacts map中，各个send_方法处理即可
-# 5. 用户创建一个虚拟的用户保存上述im群 的机器人token信息 user的contacts map中
