天翼開放平臺免費短信驗證碼接口使用實例

更新時間：2013年12月18日 15:41:52 作者：

天翼開放平臺提供了一個免費的短信驗證碼API,下面看看使用方法吧,我們用python開發(fā)接口

對于目前眾多的驗證碼解決方案來說，這個API有著中國電信這個重量級的運營商為靠山，應(yīng)該是比較靠譜的了，而且還是免費的。詳細情況請參閱：http://open.189.cn

使用方式：
#定義app_id和app_secret
r = RandCode('app_id', 'app_secret')
#支持平臺的兩種接口方式
#方式1：自定義接收驗證碼的回調(diào)URL
r.send('phone number', 'http://yourdomain/rand_code.php', '3')
#方式2：自定義驗證碼內(nèi)容
r.send_sms('phone number', 189189)

復(fù)制代碼代碼如下:

#!/usr/bin/env python
# coding: utf-8
