我在下面写了一个函数:

function getYoutubeUrlId (url) {
    const urlObject = new URL(url);
    let urlOrigin = urlObject.origin;
    let urlPath = urlObject.pathname;

    if (urlOrigin.search('youtu.be') > -1) {
        return urlPath.substr(1);
    }

    if (urlPath.search('embed') > -1) {
        // Örneğin "/embed/wCCSEol8oSc" ise "wCCSEol8oSc" return eder.
        return urlPath.substr(7);
    }

   
    return urlObject.searchParams.get('v');
},

试试这个——

function getYouTubeIdFromURL($url) 
{
  $pattern = '/(?:youtube.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu.be/)([^"&?/ ]{11})/i';
  preg_match($pattern, $url, $matches);

  return isset($matches[1]) ? $matches[1] : false;
}

试试NPM包youtube-id

测试在不同的网址:

const tested = [
  'https://www.youtube.com/watch?v={YOUTUBE_ID}&nohtml5=False',
  'https://youtu.be/{YOUTUBE_ID}',
  'www.youtube.com/embed/{YOUTUBE_ID}'
  // ....
]

截至2015年1月1日，这些都不能在厨房里工作，特别是没有http/s协议和youtube-nocookie域的url。这里有一个修改过的版本，适用于所有这些不同的Youtube版本:

// Just the regex. Output is in [1]. /^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/|shorts\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/ // For testing. var urls = [ 'https://youtube.com/shorts/dQw4w9WgXcQ?feature=share', '//www.youtube-nocookie.com/embed/up_lNV-yoK4?rel=0', 'http://www.youtube.com/user/Scobleizer#p/u/1/1p3vcRhsYGo', 'http://www.youtube.com/watch?v=cKZDdG9FTKY&feature=channel', 'http://www.youtube.com/watch?v=yZ-K7nCVnBI&playnext_from=TL&videos=osPknwzXEas&feature=sub', 'http://www.youtube.com/ytscreeningroom?v=NRHVzbJVx8I', 'http://www.youtube.com/user/SilkRoadTheatre#p/a/u/2/6dwqZw0j_jY', 'http://youtu.be/6dwqZw0j_jY', 'http://www.youtube.com/watch?v=6dwqZw0j_jY&feature=youtu.be', 'http://youtu.be/afa-5HQHiAs', 'http://www.youtube.com/user/Scobleizer#p/u/1/1p3vcRhsYGo?rel=0', 'http://www.youtube.com/watch?v=cKZDdG9FTKY&feature=channel', 'http://www.youtube.com/watch?v=yZ-K7nCVnBI&playnext_from=TL&videos=osPknwzXEas&feature=sub', 'http://www.youtube.com/ytscreeningroom?v=NRHVzbJVx8I', 'http://www.youtube.com/embed/nas1rJpm7wY?rel=0', 'http://www.youtube.com/watch?v=peFZbP64dsU', 'http://youtube.com/v/dQw4w9WgXcQ?feature=youtube_gdata_player', 'http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player', 'http://youtube.com/?v=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player' ]; var i, r, rx = /^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/|shorts\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/; for (i = 0; i < urls.length; ++i) { r = urls[i].match(rx); console.log(r[1]); }

好吧，简单解析的方法是:从第一个=符号开始到第一个&符号。

我想他们在这里有一个类似的答案:

使用JavaScript解析Vimeo ID ?

强大的Python来了

import pytube

yt = pytube.YouTube("https://www.youtube.com/watch?v=kwM2ApskJy4")

video_id = yt.video_id

print("video id from utl..",video_id)
