模拟实现msn登陆过程（MSNP15）

这几天了解了一下msn协议的登陆部分，凑了几段代码实现了，有资料的话没什么难度，主要是了解一下相关的过程和机制。下面模拟的是msn 8.5.1238 版本（实际上就是抓包然后填到程序里） 废话少说，直接开始吧（细节不说了，自己补课） 首先登陆DS服务器：messenger.hotmail.com:1863 VER 1 MSNP15 MSNP14 MSNP13 CVR0 VER 1 MSNP15 MSNP14 MSNP13 CVR0 CVR 2 0x0804 winnt 5.1 i386 MSG80BETA 8.5.1238 msmsgs test@hotmail.com USR 3 SSO I test@hotmail.com CVR 2 8.1.0178 8.1.0178 8.1.0178 http://msgruser.dlservice.microsoft.com/download/B/D/3/BD343317-2DBF-48FE-8BD9-9E3212D65E6A/Install_Messenger.exe http://get.live.com/cn XFR 3 NS 207.46.108.67:1863 U D 获得NS服务器的地址：207.46.108.67:1863，后面要用；使用https进行Passport的验证过程，获得登陆必需的ticket和BinarySecret。msnp15采用了SSO的方式进行认证。SSO，Single Sign-On，我的理解就是一次验证便可获取对应不同服务的ticket。访问https://login.live.com/RST.srf，并且POST下列xml内容
