PHP 从 shell_exec 获得一些零件

Question

我需要你们的帮助我的服务器上有一些 php 代码运行:

<?php
if ($_GET['id'])
$id = $_GET['id'];
$json = file_get_contents('http://www.youtubeinmp3.com/fetch/?format=JSON&video=http://www.youtube.com/watch?v=' . $id);
    $data = json_decode($json, true);
    $stream = $data['link'];
    $url    = $stream;



$output = shell_exec ('curl -I -L ' . $url);
echo "<pre>$output</pre>";
?>

当我转到：http://146.185.137.252/new.php?id=HgzGwKwLmgM

时它会输出这个

它输出这个：

但我不需要那些东西我只需要两件事： (Location:) 和 (Content-Disposition: attachment; filename=)

在两个不同的变量中所以在这种情况下我需要：

//w23.youtubeinmp3.com/download/get/?id=HgzGwKwLmgM&r=kT7YFcbHgX3m25ULP3GeWulVx9OmT2qd&t=Queen+-+Don%27t+Stop+Me+Now+%28Official+Video%29

和

Queen - 现在不要阻止我（官方视频）（顺便说一句，我不想要 .mp3）

我到处都在网上搜索过，但老实说，我完全是个菜鸟所以如果有人能帮助我，那就太棒了

Answer 1

如果您只想要您在问题中所写的文件名和标题。

你可以像这样简单地使用它们

$link = $data['link'];
$title = $data['title'];

一旦你有了它，你可以打印它或像这样用它制作一个 link

echo "<a href=$link>$title</a>";

除非您想保存文件，否则不需要 curl（和 shell_Exec）部分

看起来像这样：

<?php
if (isset($_GET['id'])) {
  $id = $_GET['id'];
  $json = file_get_contents('http://www.youtubeinmp3.com/fetch/?format=JSON&video=http://www.youtube.com/watch?v=' . $id);
  $data = json_decode($json, true);

  $link = $data['link'];
  $title = $data['title'];

  echo "<a href=$link>$title</a>";
  }
?>

Answer 2

此代码已经过测试。响应是从我的浏览器复制的。

我只是使用 curl 来执行 curl 请求并使用 curl_getinfo($ch,CURLINFO_REDIRECT_URL) 来获取重定向 link。

我还添加了获取 header 的功能，除非出现问题并且您希望看到响应 header.

PHP

<?php
header('content-type: text/plain');
$id='HgzGwKwLmgM';
$json = file_get_contents('http://www.youtubeinmp3.com/fetch/?format=JSON&video=http://www.youtube.com/watch?v=' . $id);
$json = json_decode($json, true);
$url = $json['link'];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
$header = curl_exec($ch);
$link = curl_getinfo($ch,CURLINFO_REDIRECT_URL);
echo "\nLINK:  $link\n\nHEADER: $header";

?>

响应：
