网络视频源地址抓包分析（1）

1、准备工具

抓包工具：firebug或httpwatch，这里我使用firebug。它是火狐自带的组件，如果浏览顺上没有可以在【工具--》附加组件--》搜索fireug安装即可】。

谷歌浏览器

记事本

2、以优酷、腾讯的例子为例。



优酷

访问优酷www.youku.com，随便找了个视频，标题是：违法司机强行开车冲撞执勤交警 被拘十日

地址：http://v.youku.com/v_show/id_XNTM2MTQ5MDcy.html



打开firebug，【网络--》选择HTML】，然后访问视频上述视频地址。此时firebug会记录的有get与post请求！如图：



待视频播放后（广告结束后，播放视频），立即点击【保持】并且暂停视频。这时候开始分析所有URL。

视频播放前，前台页面肯定会发请求给CDN服务器，来获取真实的视频源地址，从而进行播放！一般地，只需要查看所有GET请求的URL就行了。

仔细分析你会发现http://v.youku.com/player/getPlayList/VideoIDS/XNTM2MTQ5MDcy/timezone/+08/version/5/source/video?n=3&password=&ran=5169，这个URL特别可疑！

为什么可疑？我是这么想的：

1、域名现视频地址的域名一样，都是v.youku.com，其他PHP大多是系统去获取广告信息的，你可以点击看一下的。

2、大的视频网站命名都比较规范，只要跟播放相关都带有player、video等字眼。

3、另外链接有一个加密参数XNTM2MTQ5MDcy，这个与链接地址一样 ，说明它通过此链接要获取什么。

打开这个链接看看，如图：

看到没有，title标题，标签与视频的标题一样，说明这个文件内容绝对有用！
