【中文标题】如何使用 PHP 从视频 URL 中检索 YouTube 视频详细信息？【英文标题】：How can I retrieve YouTube video details from video URL using PHP? 【发布时间】：2012-06-09 09:46:36 【问题描述】：使用 php，我如何从 youtube 视频 URL 获取视频信息，例如标题、描述、缩略图，例如
http://www.youtube.com/watch?v=B4CRkpBGQzU
【问题讨论】：
developers.google.com/youtube/2.0/developers_guide_php 【参考方案1】：您可以从 youtube oembed 界面获取两种格式的数据：XML 和 JSON
接口地址：http://www.youtube.com/oembed?url=youtubeurl&format=json
使用这个PHP函数获取数据
function get_youtube($url)
$youtube = "http://www.youtube.com/oembed?url=". $url ."&format=json";
$curl = curl_init($youtube);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$return = curl_exec($curl);
curl_close($curl);
return json_decode($return, true);
$url = // youtube video url
// Display Data
print_r(get_youtube($url));
不要忘记在您的php.ini 中启用extension=php_curl.dll
【讨论】：
应在顶部添加header('Content-Type: text')，以便不解析html。
嗨，输出返回未经授权。我访问私人视频，我得到了这个输出。有什么方法可以获取详细信息？【参考方案2】：
这会返回有关视频的元数据：
http://www.youtube.com/oembed?url=videoUrlHere&format=json
使用您的示例，调用：
http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=B4CRkpBGQzU&format=json
返回以下内容，您可以使用 PHP 消化和解析：
"provider_url": "http:\/\/www.youtube.com\/",
"thumbnail_url": "http:\/\/i3.ytimg.com\/vi\/B4CRkpBGQzU\/hqdefault.jpg",
"title": "Joan Osborne - One Of Us",
"html": "\u003ciframe width=\"459\" height=\"344\" src=\"http:\/\/www.youtube.com\/embed\/B4CRkpBGQzU?fs=1\u0026feature=oembed\" frameborder=\"0\" allowfullscreen\u003e\u003c\/iframe\u003e",
"author_name": "jzsdhk",
"height": 344,
"thumbnail_width": 480,
"width": 459,
"version": "1.0",
"author_url": "http:\/\/www.youtube.com\/user\/jzsdhk",
"provider_name": "YouTube",
"type": "video",
"thumbnail_height": 360
【讨论】：
@ShurvirMori 不，结果相同，只是顺序不同。 @VighneshRaut 它与接受的答案基本相同。【参考方案3】：另一个有用的 URL API 是：https://www.youtube.com/get_video_info?video_id=B4CRkpBGQzU
video_id 是 YouTube 的 "v" 参数。结果是一个 URL 编码格式的字典 (key1=value1&key2=value2&...)
这是长期存在的无证 API，因此探索它取决于开发人员。我知道“状态”（正常/失败）、“错误代码”（在我的实践中为 100 和 150）、“原因”（错误的字符串描述）。我以这种方式获得持续时间（“length_seconds”），因为 oEmbed 不提供此信息（奇怪但真实），我几乎无法激励每个雇主从 YouTube 获取密钥以使用官方 API
【讨论】：
这有大量有用/重要的数据，但它并没有告诉你视频有多少喜欢、不喜欢和 cmets。它也没有准确地告诉您视频的上传时间； citizenevidence.amnestyusa.org 确实告诉您该数据：“视频 ID：B4CRkpBGQzU 上传日期（YYYY/MM/DD）：2007-09-21 上传时间（UTC）：03:19:20”--citizenevidence.amnestyusa.org. 【参考方案4】：要获取 youtube 视频 description、不同大小的 thumbnail、tags 等，请使用更新的 v3 googleapis
示例网址：https://www.googleapis.com/youtube/v3/videos?part=snippet&id=7wtfhZwyrcc&key=my_google_api_key
$google_api_key = 'google_api_key';
$video_id = 'youtube_video_id';
$api_url = 'https://www.googleapis.com/youtube/v3/videos?part=snippet&id='.$video_id.'&key='.$google_api_key;
$json = file_get_contents($api_url);
$obj = json_decode($json);
var_dump($obj);

【参考方案5】：我编写这个类是为了在我们的网站上显示一个 Youtube 视频：

// playlist
$video->video = "http://www.youtube.com/playlist?list=PL6F5E9FD99326F98C";
$youtube = $video->playVideo();
echo $youtube . "<hr>";
// 1 video
$video->video="http://www.youtube.com/watch?v=uTA5bLxfvwo";
$youtube = $video->playVideo();
echo $youtube;
// shared link
echo "<hr>";
$video = new YouTube(420,315);
$video->video="http://youtu.be/VRl2XFJ_tg4";
$youtube = $video->playVideo();
echo $youtube;
// invalid request
$video->video = "http://wrongvideo.com?nothere";
// Your own error message
$video->error ="<br>Video not found :-(<br>" ;
$youtube = $video->playVideo();
echo $youtube;

这门课有很多需要改进的地方。细心的眼睛可以看到次优的if 块结构和不搜索任何字母的不区分大小写的函数调用等等。我不会在专业项目中使用这个类......不是在它的当前状态。这门课需要改头换面。【参考方案6】：
我知道这是一个老问题，但我为此编写了一个包，我会把它放在这里也许有人需要这个。
composer require smoqadam/youtube-video-info:dev-master
$details = $video->getDetails();
echo $details->getVideoId();
echo $details->getTitle();
echo $details->getThumbnails();
echo $details->getViewCount();
echo $details->getRating();

嗨，赛义德，谢谢。你在哪里添加文件？【参考方案7】：这是一个可以返回多条信息的方法：
<?php
extension_loaded('openssl') or die('openssl');
$http['method'] = 'POST';
$http['header'] = 'Content-Type: application/json';
$http['content'] = <<<eof
"videoId": "lTGjFpjOIP8", "context":
"client": "clientName": "WEB", "clientVersion": "1.19700101"
eof;
$con = stream_context_create(['http' => $http]);
$key = '?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8';
echo file_get_contents(
'https://www.youtube.com/youtubei/v1/player' . $key, context: $con
);
【讨论】：
【参考方案8】：来自 oembed：
$video_url = 'https://www.youtube.com/watch?v=bHQqvYy5KYo';
$url = 'http://www.youtube.com/oembed?format=json&url=' . $video_url;
$json = json_decode(file_get_contents($url), true);
print_r($json); // it will return details of video
【讨论】：
【参考方案9】：从视频网址获取视频ID的功能
function getYTid($ytURL)
$ytvIDlen = 11; // This is the length of YouTube's video IDs
// The ID string starts after "v=", which is usually right after
// "youtube.com/watch?" in the URL
$idStarts = strpos($ytURL, "?v=");
// In case the "v=" is NOT right after the "?" (not likely, but I like to keep my
// bases covered), it will be after an "&":
if($idStarts === FALSE)
$idStarts = strpos($ytURL, "&v=");
// If still FALSE, URL doesn't have a vid ID
if($idStarts === FALSE)
die("YouTube video ID not found. Please double-check your URL.");
// Offset the start location to match the beginning of the ID string
$idStarts +=3;
// Get the ID string and return it
$ytvID = substr($ytURL, $idStarts, $ytvIDlen);
return $ytvID;
然后
$video = getYTid($videourl);
$video_feed = file_get_contents("http://gdata.youtube.com/feeds/api/videos/$video");
$sxml = new SimpleXmlElement($video_feed);
//set up nodes
$namespaces = $sxml->getNameSpaces(true);
$media = $sxml->children($namespaces['media']);
$yt = $media->children($namespaces['yt']);
$yt_attrs = $yt->duration->attributes();
//vars
$video_title = $sxml->title;
$video_description = $sxml->content;
$video_keywords = $media->group->keywords;
$video_length = $yt_attrs['seconds'];
