+通知类定义:
+```
+InfoData:
+    date: 当前日期（包括星期几）
+    time: 当前时间
+    course_time: 课程开始时间
+    course_name: 课程名称
+    course_teacher: 教师名称
+    course_location: 上课地点
+    course_time_interval: 距上课剩余时间，根据上文计算
+```
+通知格式参考InfoData内容
+
+通知形式：参考下方bash脚本，将ip换为192.168.12.1,uid、路径均不变。抽取为方法
+```
+#!/bin/bash
+msg=$1
+json=$(jq -n --arg msg "$msg" --argjson uid 2998813882 '{user_id: $uid, message: $msg}')
+curl -s -o /dev/null -X POST http://127.0.0.1:3000/send_private_msg \
+     -H "Content-Type: application/json" \
+     -d "$json"
+```
+
+定义方法publish_info负责推送，该类只暴露publish_info方法，如果涉及其他方法以及字段，均需要以`_`开头进行私有化
