挖掘视频网站【优酷】上被截断的视频的地址--002
发布时间：2020-12-14 03:52:41 所属栏目：大数据 来源：网络整理
导读：上一篇博客（这里）寻找视频地址的时候，有些细节没有弄很清楚，这两天继续弄，发现原来路径里边的sid是个随机生成数，不需要找它。对于k值，现在的是服务器直接返回来的，而里边也有通过返回的json里边的key1计算获得： PlayListProxy.as文件里边: param1.k

上一篇博客（这里）寻找视频地址的时候，有些细节没有弄很清楚，这两天继续弄，发现原来路径里边的sid是个随机生成数，不需要找它。对于k值，现在的是服务器直接返回来的，而里边也有通过返回的json里边的key1计算获得： PlayListProxy.as文件里边: param1.key1 = (Number("0x" + param2.key1) ^ Number("0xA55AA5A5")).toString(16);
而关键之处是就剩下了那个fileid，这是我从它的播放器里边找到的源码： private function parseMainData(param1:PlayListData,param2:Object) : void
{
var _loc_5:String = null;//临时变量
var _loc_9:String = null;//临时变量
var _loc_10:String = null;//flvmp4分段视频信息
var _loc_11:Object = null;//streamfileids
var _loc_12:String = null;
var _loc_13:Array = null;
var _loc_14:RandomProxy = null;
var _loc_15:Dictionary = null;//segs里边几种视频类型的数据
var _loc_16:String = null;//视频类型
var _loc_17:int = 0;//临时变量，长度计数用
var _loc_18:String = null;
var _loc_19:Array = null;//存放视频数据
var _loc_20:String = null;
var _loc_21:Object = null;//临时变量
var _loc_22:VideoSegmentData = null;//视频数据：no,size.type,seconds,k值

_loc_22.fileId = this.getFileId(_loc_11,_loc_14); 知道它是计算fileId的关键代码，但是RandomProxy是什么结构的有人知道吗？为什么怎么搜索都找不到呢？ getFileId函数代码： //streamfileids,RandomProxy(param1.seed)

{
var _loc_6:String = null;//mp4/flv

比如fileid是：0300080400510C15B61CF004ED56DCBD905FF1-B527-63DA-87D3-6C0D90F804E1 很显然，_loc_9得到的是前边8位，_loc_11得到的是中间两位，而_loc_12是通过函数cg_fun()得到的那个字符串出去前边被替换的10位的剩余字符串。 所有的核心就剩下这个函数了，一时间找不到办法解决，之后查了一下其他人做的方法，那些几乎都是以前的早起版本，但是现在依然可以用： ?最新的优酷真实下载地址解析 http://blog.csdn.net/feige2008/article/details/8198434? 优酷视频真实地址解析?http://blog.csdn.net/amor2006/article/details/7055902
