这是大家流传的看视频方法：

其中vid=125936631就是视频VID。
现在问题来了：

解决方法1：使用硕鼠，直接将上面的链接输入进去解析。

解决方法2：改变发给v_play.php的请求：
之前：
/v_play.php
?vid=125936631
&uid=0
&pid=0
&tid=0
&plid=4004
&prid=ja_7_5986379099
&referrer=
&ran=0.5436820345930755
&r=p.you.video.sina.com.cn
&v=4.4.42.32
&p=i
&k=477ef81e4db7a75521928141
之后：
/v_play.php
?vid=125936631
&uid=0
&pid=0
&tid=0
&plid=4004
&prid=ja_7_5986379099
&referrer=http%3A%2F%2Fvideo.sina.com.cn%2F
&ran=0.5436820345930755
&r=video.sina.com.cn
&v=4.4.42.32
&p=i
&k=477ef81e4db7a75521928141
看出差别了吧。
