c++模拟会话登录，访问QQ的SSO，读取ClientKey，不需要注入，读取QQ ClientKey C++版本

需要注意的是，这种方法获取的clientkey长度是224位，和之前注入dll获取的不一样。

注入dll获取的是64位的clientkey

利用方法：
64字节： http://ptlogin2.qq.com/jump?ptlang=2052&clientuin=QQ号码&clientkey=64个字节的KEY&u1=需要登陆的QQ服务网站地址
224字节： http://ptlogin2.qq.com/jump?clientuin=QQ号&clientkey=224位字节的KEY&keyindex=9&u1=需要登陆的QQ服务网站地址

例如，我想利用224字节的key，无密进入qq邮箱

用浏览器访问下面构造的地址，成功后会返回一个地址，复制再访问，就直接进入QQ邮箱了
http://ptlogin2.qq.com/jump?clientuin=QQ号&clientkey=224字节key&keyindex=9&u1=https%3A%2F%2Fmail.qq.com%2Fcgi-bin%2Flogin%3Fvt%3Dpassport%26vm%3Dwpt%26ft%3Dloginpage%26target%3D&pt_local_tk=&pt_3rd_aid=0&ptopt=1&style=25
