天翼开放平台免费短信验证码接口使用实例

对于目前众多的验证码解决方案来说，这个api有着中国电信这个重量级的运营商为靠山，应该是比较靠谱的了，而且还是免费的。详细情况请参阅：http://open.189.cn

使用方式：
#定义app_id和app_secret
r = randcode('app_id', 'app_secret')
#支持平台的两种接口方式
#方式1：自定义接收验证码的回调url
r.send('phone number', 'http://yourdomain/rand_code.php', '3')
#方式2：自定义验证码内容
r.send_sms('phone number', 189189)

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