使用Ruby，你可以做以下事情，比如:

url                      = "http://www.vimeo.com/7592893"
vimeo_video_id           = url.scan(/vimeo.com\/(\d+)\/?/).flatten.to_s               # extract the video id
vimeo_video_json_url     = "http://vimeo.com/api/v2/video/%s.json" % vimeo_video_id   # API call

# Parse the JSON and extract the thumbnail_large url
thumbnail_image_location = JSON.parse(open(vimeo_video_json_url).read).first['thumbnail_large'] rescue nil

我写了一个函数在PHP让我这，我希望它对某人有用。缩略图的路径包含在视频页面的链接标记中。这似乎对我有用。

    $video_url = "http://vimeo.com/7811853"  
    $file = fopen($video_url, "r");
    $filedata = stream_get_contents($file);
    $html_content = strpos($filedata,"<link rel=\"videothumbnail");
    $link_string = substr($filedata, $html_content, 128);
    $video_id_array = explode("\"", $link_string);
    $thumbnail_url = $video_id_array[3];
    echo $thumbnail_url;

希望能对大家有所帮助。

下面是一个如何在ASP中做同样的事情的例子。NET使用c#。请随意使用不同的错误捕获图像:)

public string GetVimeoPreviewImage(string vimeoURL)
{
    try
    {
        string vimeoUrl = System.Web.HttpContext.Current.Server.HtmlEncode(vimeoURL);
        int pos = vimeoUrl.LastIndexOf(".com");
        string videoID = vimeoUrl.Substring(pos + 4, 8);

        XmlDocument doc = new XmlDocument();
        doc.Load("http://vimeo.com/api/v2/video/" + videoID + ".xml");
        XmlElement root = doc.DocumentElement;
        string vimeoThumb = root.FirstChild.SelectSingleNode("thumbnail_medium").ChildNodes[0].Value;
        string imageURL = vimeoThumb;
        return imageURL;
    }
    catch
    {
        //cat with cheese on it's face fail
        return "http://bestofepicfail.com/wp-content/uploads/2008/08/cheese_fail.jpg";
    }
}

注意:当被请求时，你的API请求应该像这样:http://vimeo.com/api/v2/video/32660708.xml

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 + '"/>');
});

我创建了一个code depen来为您获取图像。

https://codepen.io/isramv/pen/gOpabXg

HTML

<input type="text" id="vimeoid" placeholder="257314493" value="257314493">
<button id="getVideo">Get Video</button>
<div id="output"></div>

JavaScript:

const videoIdInput = document.getElementById('vimeoid');
const getVideo = document.getElementById('getVideo');
const output = document.getElementById('output');

function getVideoThumbnails(videoid) {
  fetch(`https://vimeo.com/api/v2/video/${videoid}.json`)
  .then(response => {
    return response.text();
  })
  .then(data => {
    const { thumbnail_large, thumbnail_medium, thumbnail_small } = JSON.parse(data)[0];
    const small = `<img src="${thumbnail_small}"/>`;
    const medium = `<img src="${thumbnail_medium}"/>`;
    const large = `<img src="${thumbnail_large}"/>`;
    output.innerHTML = small + medium + large;
  })
  .catch(error => {
    console.log(error);
  });
}

getVideo.addEventListener('click', e => {
  if (!isNaN(videoIdInput.value)) {
    getVideoThumbnails(videoIdInput.value);
  }
});

如果你想通过纯js/jquery没有api使用缩略图，你可以使用这个工具从视频中捕获一帧，瞧!插入url拇指在任何你喜欢的来源。

这是一支码笔:

<img src="https://i.vimeocdn.com/video/531141496_640.jpg"` alt="" />
