java調用企業微信接口API發送消息(替代短信驗證碼的一種解決方案)
文章採納源地址：https://www.cnblogs.com/kuzaman/p/6564632.html
使用微信發送驗證碼配置頁面：
以下步驟獲取頁面上的參數
1、註冊企業微信：
註冊成功後微信掃碼/企業微信掃碼進行登陸
登陸成功頁面：
2、獲取企業ID
3、點擊企業應用創建一個用來發送驗證碼的應用
驗證碼應用頁面：這裏獲取企業應用的id【agentID】和管理組的憑證祕鑰【CorpSecret】
4、body是你要發送的文本信息【可以是任意內容但是有文本長度的限制】
5、ToUser這個參數是成員的賬號【大小寫都可以】
6、如何加入新的成員
掃描下方二維碼下載企業微信，註冊加入企業
掃描下方二維碼，關注企業微信插件即可通過微信接収消息
7、後臺代碼：
依賴包：
