短信驗(yàn)證碼/通知 - 代碼示例

//接口類型：短信接口
//測試環(huán)境：centos7.8 gcc4.8.5
//測試日期：2022-01-26
//使用說明：demo只包含了對接時需要的傳參和解析的核心代碼，可參考整合到自己的系統(tǒng)中，具體業(yè)務(wù)細(xì)節(jié)代碼可根據(jù)自己的需要進(jìn)行調(diào)整及優(yōu)化。
//linux下的編譯：gcc -o test ./test.c
//linux下的執(zhí)行：./test

//接口類型：互億無線觸發(fā)短信接口，支持發(fā)送驗(yàn)證碼短信、訂單通知短信等。
//賬戶注冊：請通過該地址開通賬戶http://sms.ihuyi.com/register.html
//注意事項(xiàng)：
//（1）調(diào)試期間，請用默認(rèn)的模板進(jìn)行測試，默認(rèn)模板詳見接口文檔；
//（2）請使用APIID（查看APIID請登錄用戶中心->驗(yàn)證碼短信->產(chǎn)品總覽->APIID）及APIkey來調(diào)用接口；
//（3）該代碼僅供接入互億無線短信接口參考使用，客戶可根據(jù)實(shí)際需要自行編寫；
