天翼开放平台免费短信验证码Python版SDK，pythonsdk,天翼开放平台提供了一个免

天翼开放平台提供了一个免费的短信验证码API。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)
