近期公司做了一款OTP令牌激活的产品，因为之前激活手机令牌须要输入非常多的激活信息才干进行激活。

经过一段使用后，发现易用性不是非常强，考虑假设添加二维码的的扫码功能岂不是大大添加了易用性。

     在网上搜了非常多资料，要不是配置太多，要不就是代码量太大。最后没办法就硬着头皮去写和去精简,最后压缩至眼下的版本号。

假设有更好的版本号能够联系我。  

        详细DEMO能够通过 下载http://download.csdn.net/detail/fugui6611634/7341277下载

        本文代码执行的结果例如以下：

      代码的结构例如以下：

        以下主要来看一下配置文件：
