在javascript中(使用jQuery):

function vimeoLoadingThumb(id){    
    var url = "http://vimeo.com/api/v2/video/" + id + ".json?callback=showThumb";

    var id_img = "#vimeo-" + id;

    var script = document.createElement( 'script' );
    script.src = url;

    $(id_img).before(script);
}


function showThumb(data){
    var id_img = "#vimeo-" + data[0].id;
    $(id_img).attr('src',data[0].thumbnail_medium);
}

要显示它:

<img id="vimeo-{{ video.id_video }}" src="" alt="{{ video.title }}" />
<script type="text/javascript">
  vimeoLoadingThumb({{ video.id_video }});
</script>

对于像我这样最近正试图弄清楚这个问题的人来说，

(其中尺寸= 200x150 | 640)

分解Karthikeyan P的答案，使其可以用于更广泛的场景:

// Requires jQuery

function parseVimeoIdFromUrl(vimeoUrl) {
  var match = /vimeo.*\/(\d+)/i.exec(vimeoUrl);
  if (match)
    return match[1];

  return null;
};

function getVimeoThumbUrl(vimeoId) {
  var deferred = $.Deferred();
  $.ajax(
    '//www.vimeo.com/api/v2/video/' + vimeoId + '.json',
    {
        dataType: 'jsonp',
        cache: true
    }
  )
  .done(function (data) {
    // .thumbnail_small 100x75
    // .thumbnail_medium 200x150
    // 640 wide
        var img = data[0].thumbnail_large;
        deferred.resolve(img);  
    })
  .fail(function(a, b, c) {
    deferred.reject(a, b, c);
  });
  return deferred;
};

使用

从Vimeo视频URL获取Vimeo Id:

var vimeoId = parseVimeoIdFromUrl(vimeoUrl);

从vimeo Id获取一个vimeo缩略图URL:

getVimeoThumbUrl(vimeoIds[0])
.done(function(img) {
    $('div').append('<img src="' + img + '"/>');
});

        var type = 'vimeo';
    }

    return {

如果您不需要自动解决方案，您可以通过在这里输入vimeo ID: http://video.depone.eu/来找到缩略图URL

你可能想看看马特·胡克斯的宝石。https://github.com/matthooks/vimeo

它为api提供了一个简单的vimeo包装器。

所有你需要的是存储video_id(和提供商，如果你也做其他视频网站)

你可以像这样提取vimeo视频id

def 
  get_vimeo_video_id (link)
        vimeo_video_id = nil
        vimeo_regex  = /http:\/\/(www\.)?vimeo.com\/(\d+)($|\/)/
        vimeo_match = vimeo_regex.match(link)


if vimeo_match.nil?
  vimeo_regex  = /http:\/\/player.vimeo.com\/video\/([a-z0-9-]+)/
  vimeo_match = vimeo_regex.match(link)
end

    vimeo_video_id = vimeo_match[2] unless vimeo_match.nil?
    return vimeo_video_id
  end

如果你需要你的试管，你可能会发现这个很有用

def
 get_youtube_video_id (link)
    youtube_video_id = nil
    youtube_regex  = /^(https?:\/\/)?(www\.)?youtu.be\/([A-Za-z0-9._%-]*)(\&\S+)?/
    youtube_match = youtube_regex.match(link)

if youtube_match.nil?
  youtubecom_regex  = /^(https?:\/\/)?(www\.)?youtube.com\/watch\?v=([A-Za-z0-9._%-]*)(\&\S+)?/
  youtube_match = youtubecom_regex.match(link)
end

youtube_video_id = youtube_match[3] unless youtube_match.nil?
return youtube_video_id
end
