通过JSON获取Youtube信息,以获取Javascript中的单个视频(非Feed)

Question

所以我试图通过JSON格式从单个YouTube视频中获取信息.像标题描述类别一样,除了评论之外我还能得到什么.我想在Javascript中这样做.我注意到下面的链接,但他们的所有示例都是如何从Feed中获取视频信息.我想从一个视频中获取信息,假设我知道它的ID.

https://developers.google.com/youtube/2.0/developers_guide_json

我也在看这个Stackoverflow问题, 但我有一个问题,它说"test.js(第10行)GET http://gdata.youtube.com/feeds/api/videos/VA770w...v = 2 ALT = JSON-在脚本&回调=列表信息

200 OK 9ms"

简而言之,如果我有一个像VA770wpLX-Q这样的YouTube视频ID,那么网址在JSON中获取视频信息会是什么样的？

谢谢

2018年更新

API v2已弃用.新的youtube api v3仅适用于开发人员令牌,并且对免费连接有限制.

你可以在没有API的情况下获得JSON:

http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=ojCkgU5XGdg&format=json

或者xml

http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=ojCkgU5XGdg&format=xml

其中UCkA21M22vGK9GtAvq3DvSlA是您的频道ID.您可以在"我的频道"链接上的youtube帐户中找到它.

Answer 2

2015年5月更新:

此解决方案无法正常运行,YouTube API v2正在制作过程中即将停止.

有关详细信息,请访问:https: //www.youtube.com/devicesupport

尝试这样的事情:

var video_id='VA770wpLX-Q';

$.getJSON('http://gdata.youtube.com/feeds/api/videos/'+video_id+'?v=2&alt=jsonc',function(data,status,xhr){
    alert(data.data.title);
    // data contains the JSON-Object below
});

演示:http://jsfiddle.net/wqwxg/

返回的JSON如下所示:

Answer 3

问题

YouTube API不支持JSONP - 请参阅问题4329:针对JSONP的oEmbed回调.此外,不推荐使用YouTube Data API v2.

解

您可以使用Noembed服务通过JSONP for YouTube视频获取oEmbed数据.

奖金

• 不需要API密钥
• 不需要服务器端代理

例

对于您的VA770wpLX-Q视频,您可以尝试以下链接:

https://noembed.com/embed?url=http://www.youtube.com/watch?v=VA770wpLX-Q

或者对于JSONP:

https://noembed.com/embed?callback=example&url=http://www.youtube.com/watch?v=VA770wpLX-Q

这些链接具有作为url参数传递的YouTube视频的标准网址.它不仅适用于YouTube,还适用于Vimeo和其他网址,例如:

https://noembed.com/embed?url=https://vimeo.com/45196609

演示

这是一个使用jQuery的简单示例:

var id = 'VA770wpLX-Q';
var url = 'https://www.youtube.com/watch?v=' + id;

$.getJSON('https://noembed.com/embed',
    {format: 'json', url: url}, function (data) {
    alert(data.title);
});

请参阅:JS Bin上的DEMO.

其他选择

• 嵌入式(商业服务,每月最多免费5000个URL)
• Oohembed(更新:现在由Embedly购买,但来源可用)
• AutoEmbed(更新:似乎已关闭或已停止)

更多信息

另见这些问题:

• 没有API密钥的API v3的Youtube视频标题？
• 对youtube oembed调用的JSONp请求的响应给出"无效标签"错误

Answer 4

在第3节:

$.getJSON('https://www.googleapis.com/youtube/v3/videos?id={videoId}&key={myApiKey}&part=snippet&callback=?',function(data){

 if (typeof(data.items[0]) != "undefined") {
     console.log('video exists ' + data.items[0].snippet.title);
   } else {
     console.log('video not exists');
 }   
});

作为对@Jonathan服务器端的回应,使用PHP和CURL:

$url = "https://www.googleapis.com/youtube/v3/videos?id=".$videoId."&key=".$miApikey."&part=snippet";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$output=curl_exec($ch);                 
$response = json_decode($output, TRUE);
print_r($response);
