目的：給關注用戶推送消息
場景：自動化測試,運維監控，接口訪問等報錯預警。例如線上接口報錯，發送提醒消息
准備工作：
1:注冊企業號（為什么不用公眾號呢？）
2:常用參數介紹：
1:CORPID 企業號唯一標志符號。 位置：點擊首頁企業名稱，企業資料中有key：CorpID 2:CORPSECRET： 需要創建單獨等應用。具體步驟，按照提示一步一步來即可。需關注2個參數 Secret 和 AgentId（用於區分給哪個應用推送消息） 3:發送消息准備工作：
關注自己的企業號。（需要先綁定手機號）
4:紀錄下需要發送消息的通訊錄Id
用於給指定用戶推送消息
5:代碼結構
1:獲取token
2:發送消息
6源碼：（在你執行下面代碼的時候，AgentId改為你自己的）
