webqq机器人实现

webqq机器人,实现支持虚拟空间,异步后台执行,使用了fsockopen 函数模拟浏览器请求,并把相关cookie保存,在下一次请求时再发送到原始的header头里,目前代码还未很完善,也需要web登陆窗口的支持。
webQQ登陆流程:QQ登陆窗口 输入QQ号后验证QQ相关信息,查看是否需要返回验证码,如果需要则返回验证码,输入密码后提交登陆时生成相关的加密串,并提交到腾讯的网站用户登陆验证接口,此时仅仅是登陆到了腾讯网站,再提交一次到webqq登陆网关实现QQ的登录,返回登录成功后就获取相关的cookie。

异步挂起实现:使用fsockopen访问启动qq在线的web地址,无需等待直接返回,qq在线的web地址就使用while来获取qq返回的聊天信息(qq.class.php main 方法)
