QQ开放平台 OAUTH2.0 QqConnetSDK 登录，运行原理，附源码。
供大家研究使用，您可以对源代码进行修正编写。有很多不足，有很多缺点，在这里我只编写原理。
您需要开放式站点，做为了解它，您需要编写补充很多，或者您可以按照我的使用提供下载，进行编写其余内容补充及修正。谢谢大家，让大家的站点也融合这玩意。
开发环境：vs2005
QqConnetSDK
// 默认“Microsoft XML,v3.0”,其他版本也可以，只要能编译通过，步骤如下。
// 添加引用 -> “COM” 选项卡 -> 找到组件名称为“Microsoft XML,v3.0”

QqConnetSDK 项目sdk
QqConnet QqConnet基础类 ；您可以改进
ConfigurationHandler 配置节点句柄类 ；用于扩展配置文件节点，您可以改进
JSON JSON分析类 ；您可以改进
UserInfo 用户实体类 ；您可以改进，其他实体类不在一一列出，自行扩展。
