我尝试使用代码

<?php

      $ch = curl_init("//lh3.googleusercontent.com/gNqSDOMdfLcZDOv1j7TGfEQSzXrk0ngBSloMd6JSjGQ=m22");
      curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
      curl_setopt($ch, CURLOPT_HEADER, true); 
      curl_setopt($ch, CURLOPT_NOBODY, true); 
      $response = curl_exec($ch); 
      $resolved = curl_getinfo($ch); 
      echo $resolved['url']; 
  ?>

：//r8---sn-ab5l6nel.googlevideo.com/videoplayback ID = f091f46ecaa177ea＆安培; ITAG = 22＆安培;源= Picasa和安培;开始= 0＆安培; requiressl = YES＆安培;毫米= 30＆安培; MN = SN-ab5l6nel＆安培; MS = NXU＆安培; MV = U＆安培; PL = 48＆安培; MIME =视频/ MP4＆安培; LMT = 1438598135161434＆安培; MT = 1448012329＆安培; IP = 2604：A880：800：A1 :: 75：6001＆安培; ipbits = 48＆安培;到期= 1448042024＆安培; sparams = IP，ipbits，到期，ID，ITAG，来源，requiressl，毫米，MN，MS，MV，PL，MIME，LMT＆安培;签名= 9259AF5059FA660980BB65F95637C73690207B67.3F352385B6D53E5FF4938A859338554D90173F7A＆安培;键= CK2

我很高兴，但它没有运行。

非常感谢！

我知道您要执行的操作并且视频无法播放，因为您收到的响应不会包含Access-Control-Origin-Policy标头。这意味着浏览器无法访问没有该标头的响应接收。这是出于安全目的。如果要解决此问题，您必须将https://r2---sn-i3b7kn7z部分替换为https://redirector。
