通过JSON获取Javascript中单个视频（非提要）的Youtube信息

所以我试图通过一个youtube视频获取JSON格式的信息。像标题描述类，等等，除了评论之外我还能得到什么。我正试图用Javascript实现这一点。我注意到下面的链接，但他们所有的例子都是如何从feed获取视频信息。假设我知道它的ID，我想从单个视频中获取信息

我也在看这个，但我对它所说的get请求有一个问题 “test.js（第10行） 得到

200行 9毫秒”

简言之，如果我有一个像VA770wpLX-Q这样的youtube视频id，那么用JSON获取视频信息的url会是什么样子？

谢谢

此解决方案无法正常工作，YouTube API v2即将停止使用

试着这样做：

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

2018年更新

API v2已弃用。新的youtube api v3仅适用于开发者令牌，并且对免费连接有限制

您可以在不使用API的情况下获取JSON：

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

或xml

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

新的2018 json响应已经发布

{
  "html": "<iframe width=\"480\" height=\"270\" src=\"https://www.youtube.com/embed/ojCkgU5XGdg?feature=oembed\" frameborder=\"0\" allow=\"autoplay; encrypted-media\" allowfullscreen></iframe>",

以及如何嵌入youtube live

https://www.youtube.com/embed/live_stream?channel=UCkA21M22vGK9GtAvq3DvSlA

其中UCkA21M22vGK9GtAvq3DvSlA是您的频道id。 你可以在youtube账户的“我的频道”链接上找到它

在v3中：

使用PHP和CURL，通过服务器端响应@Jonathan：

$url = "https://www.googleapis.com/youtube/v3/videos?id=".$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);

问题 YouTube API不支持JSONP，正如它应该支持的那样-请参阅。 也

解决方案 您可以使用该服务获取YouTube视频的数据

奖金

• 不需要API密钥
• 不需要服务器端代理

例子 对于

VA770wpLX-Q

视频，您可以尝试以下链接：

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

        },
        "player": {
            "default": "http://www.youtube.com/watch?v=VA770wpLX-Q&feature=youtube_gdata_player"

        },
        "restrictions": [{
            "type": "country",
            "relationship": "deny",

            "autoPlay": "denied",
            "syndicate": "allowed"
        }
    }
}

或者，对于JSONP：

这些链接具有作为

URL

参数传递的YouTube视频的标准URL。它不仅适用于YouTube，也适用于Vimeo和URL，如：

演示 下面是一个使用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：关于JS-Bin

其他选择

• （商业服务，每月免费提供多达5000个URL）
• （更新：现由Embedly购买，但可用）
• （更新：似乎已停止或停止）

发布您已经尝试过的jquery代码。jquery不是我的问题，我只是想不出获取json数据的正确url或模式。下面的答案为我指明了正确的方向url=”“这就是你的做法。NWHfY_lvKIQ是视频的ID。在那之后，你可以做一个$.getJSON（url，函数（数据）{并从那里获取json我想问一下如何获取格式为HH:MM:ss的持续时间，因为在json文件中，它是在几秒钟内，是否有任何函数可以做到这一点！！不再支持

“error”：{“code”：410，“message”：“不再可用”

遗憾的是，oembed不支持jsonp（即回调），因此在浏览器中跨域使用它将是一个问题。@BlaM我可以用jsonp加载它，但jQuery无法分析响应：-（这就是我的意思。YouTube服务器不支持为那些oEmbed发送JSONP。@Alexufo您可以使用您的网站后端代理该连接。这种方式可以工作，但这样显示密钥似乎不是一个好主意。最好使用ajax调用服务器端脚本来获取该连接url@JonathanGoogle提供了一个类似这样的API密钥，这样你就可以公开使用它。这些限制是在Google端设置的。这是做需要的事情的正确方法。API密钥不能在你通过控制台允许的域之外使用。这一切在控制台中都非常清楚。@BobSinclar谢谢。它也适用于Vimeo和其他网站，请参阅：@KenSharp如果第一方不可信（并且），那么我们可以告诉原始海报，这是不可能做到的，或者我们可以使用第三方服务来解决问题。但是如果你有更好的解决方案，请发布一个答案。知道Noembed是如何做到的吗？@jakob.j这是开源的。所以，是的。
