我是靠谱客的博主害怕小熊猫，最近开发中收集的这篇文章主要介绍天翼开放平台免费短信验证码接口使用实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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)

复制代码代码如下:

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

from time import strftime, localtime
import urllib, urllib2, json
import hmac, hashlib

class RandCode(object):

APP_ID = ''
