youtube - 给定视频网址，如何从 Youtube API 获取 Youtube 视频 ID？

我有一个页面，用户可以在其中粘贴 Youtube 视频 url，然后我需要提取视频的 ID 以获取视频的缩略图。困难的部分是获得一种从视频 url 中提取视频 ID 的可靠方法。这里有许多正则表达式解决方案，但对我来说，这些解决方案都不是 100% 可靠的。这里有一些:

  • JavaScript REGEX: How do I get the YouTube video id from a URL?
  • Youtube API - Extract video ID

    • 这就像一场关于谁拥有更长正则表达式的比赛。我觉得正确的方法是从 Youtube 的 api 中获取此信息，但查看它，似乎此选项不可用:

    https://developers.google.com/apis-explorer/#p/youtube/v3/

    如您所见，一切都基于视频 ID。我觉得我需要实际的视频 ID 来获取有关视频的任何信息是荒谬的，因为现实世界中的用户甚至都不知道视频 ID 是什么。 Vimeo 在其 API 中内置了此功能。下面是一个例子:

    https://vimeo.com/api/oembed.json?url=https://vimeo.com/29474908

    有没有人有一个不涉及一些正则表达式的解决方案？

    做一个 search with the API适用于不同的 YouTube URL 类型。 URL 作为查询项 chuyển khoảnq .

    https://www.googleapis.com/youtube/v3/search/?key=&part=snippet&q=youtu.be/M7lc1UVf-VE

    也许某些情况可能会导致多个项目，但正常的搜索结果只是一个匹配项: 

    {

    我测试了来自 this answer 的一些 URL 变体大多数工作: 

    var urls = [
        '//www.youtube-nocookie.com/embed/M7lc1UVf-VE?rel=0',
        'https://www.youtube.com/watch?v=M7lc1UVf-VE&feature=channel',
        'https://www.youtube.com/watch?v=M7lc1UVf-VE&playnext_from=TL&videos=osPknwzXEas&feature=sub',
        'https://www.youtube.com/ytscreeningroom?v=NRHVzbJVx8I', // <---- invalid
        'https://youtu.be/M7lc1UVf-VE',
        'https://www.youtube.com/watch?v=M7lc1UVf-VE&feature=youtu.be',
        'https://youtu.be/M7lc1UVf-VE',
        'https://www.youtube.com/watch?v=M7lc1UVf-VE&feature=channel',
        'https://www.youtube.com/watch?v=M7lc1UVf-VE&playnext_from=TL&videos=osPknwzXEas&feature=sub',

        'https://youtube.com/v/M7lc1UVf-VE?feature=youtube_gdata_player',
        'https://youtube.com/vi/M7lc1UVf-VE?feature=youtube_gdata_player', // <---- invalid
        'https://youtube.com/?v=M7lc1UVf-VE&feature=youtube_gdata_player',
        'https://www.youtube.com/watch?v=M7lc1UVf-VE&feature=youtube_gdata_player',
        'https://youtube.com/?vi=M7lc1UVf-VE&feature=youtube_gdata_player', // <---- invalid
        'https://youtube.com/watch?v=M7lc1UVf-VE&feature=youtube_gdata_player',
        'https://youtube.com/watch?vi=M7lc1UVf-VE&feature=youtube_gdata_player',
        'https://youtu.be/M7lc1UVf-VE?feature=youtube_gdata_player'
    ];

    var my_key = '';

    function getUri(uri){
        $.get('https://www.googleapis.com/youtube/v3/search/?key='+my_key+'&part=snippet&q='+uri, function(data) {
            if(data.items.length !== 0)
                console.log(data.items[0].snippet.publishedAt);
            khác
                console.warn('no items for',uri)
        });
    }

    for (i = 0; i < urls.length; ++i) {
        getUri(urls[i]);
    }
