video - 如何通过优酷获取直接视频下载链接

Question

我正在尝试从优酷获取直接文件下载链接。

示例网址：http: //v.youku.com/v_show/id_XNDU0MTgxNzI0.html

我使用了一个视频下载网站，试图模仿下载路径。我使用了 hxxp://flvcd 。com 来解析链接。（您可以将示例 URL 粘贴到搜索字段中，然后您将得到结果，应该有 4 个链接）。

获得 4 直接链接后，我使用 fiddler2 捕获 HTTP 输出。我能够找到视频的第一部分（根据 flvcd 网站应该有 4 个）

我尝试在页面源中搜索直接下载链接字符串，但找不到任何匹配项。我想实际的直接链接是使用网站 javascript 获取的？

有人可以对此有所了解吗？

这是我正在使用的代码；我从 SO 上的另一个答案中找到了它，但我现在找不到它..

<?php
