网上帖子基本上获得的都是假路径，用httpclient根本无法下载视频
例如：
优酷视频地址：http://v.youku.com/v_show/id_XNDM2NTcyOTM2.html?f=17977385
虚假地址：http://static.youku.com/v1.0.0255/v/swf/player.swf
用firebug获得视频的路径：其实真实路径是：http://119.167.222.14/youku/65716DFC6F9388254A1CF6480D/0300080100502107179D450727D0CD7450768F-5C38-9529-5B70-574065346233.mp4 视频大小为：4.9M怎样运用java程序获得视频的真实路径，并且下载？？

这个是网页中内嵌视频的方法
这是一个播放器：http://static.youku.com/v1.0.0255/v/swf/player.swf
这些是请求参数：

这个是硕鼠网站会把你嗅出真是的下载地址，然后你去爬取这个里面给你的真实地址
