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

我使用了一个试图模仿下载路径的视频下载网站。我使用了hxxp：// flvcd。 com解析链接。（您可以在搜索字段中粘贴示例网址，然后您将获得结果，应该有4个链接。）

一旦我获得了4个直接链接，我使用fiddler2来捕获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）

我已尝试搜索页面源中的直接下载链接字符串，但找不到任何匹配项。我想使用网站javascript获取实际的直接链接？

有人可以对此有所了解吗？

这是我正在使用的代码;我从SO的另一个答案中解决了这个问题，但我现在找不到它了。

<?php

class VideoUrlParser{
    private $video_code;
    private $video_type;
    private $success;

    public function __construct($url = null, $type = null) {
        $this->success = false;

        if(!empty($url) && !empty($type)) {
            $this->video_code = trim($url);
            $this->video_type = trim($type);
            $this->success = true;
            return;
        }

        if(!empty($url)) {
            $urls = parse_url(trim($url));

            //url is http://youtu.be/xxxx
            if($urls['host'] == 'youtu.be'){
                $this->video_code = ltrim($urls['path'],'/');
                $this->video_type = "youtube";
                $this->success = true;
            }
            else if($urls['host'] == 'youtube.com' || $urls['host'] == 'www.youtube.com'){
                $this->video_type = "youtube";

                //url is http://www.youtube.com/embed/xxxx
                if(strpos($urls['path'],'embed') == 1){
                    $this->video_code = end(explode('/',$urls['path']));
                    $this->success = true;

                    if(preg_match($regExp, $urls['path'], $url_parts)){
                        $this->video_code = $url_parts[1];

            }
            return;

    public function success() {

        } else if($this->video_type == "youku") {
