有一款针对视频网站的广告进行屏蔽的chrome插件做的比较好，其在360浏览器市场上排名非常靠前。

在使用过程中发现它在页面中插入了一段代码

[html] view plaincopy
<div class="player" id="player" err="">  
    <object type="application/x-shockwave-flash" data="http://opengg.guodafanli.com/swf/kafan/loader.swf" width="100%" height="100%" id="movie_player">

                    </span>  
                </div>  
            </div>  
        </div>

</div>  

把优酷的播放器换成了自己的播放器。

[html] view plaincopy
<a target=_blank href="http://opengg.guodafanli.com">http://opengg.guodafanli.com</a>  

在页面打开过程中，还要访问下面的网址：

http://app2.522.com.cn

这个就更奇怪了，这个网站经查是注册在

还注册了以下的网站：

[plain] view plaincopy
GET http://app2.522.com.cn/playlist2.php/v.youku.com/player/getPlayList/VideoIDS/XODI3MzIyNzgw/timezone/+08/version/5/source/video/Type/Folder/Fid/23073811/Pt/0/Ob/1?ctype=10&password=&n=3&ran=1731&ev=1 HTTP/1.1

Accept-Encoding: gzip,deflate,sdch

以上请求返回的是以下数据，看起来是优酷的视频分段信息。

在该插件第一次运行时，会从网上下载一些脚本，

http://sub.adtchrome.com/html5player.txt

http://sub.adtchrome.com/videoadjs.txt

都是经过base64加密的。

很容易解密。

主要的脚本如下：
