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

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

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。

这是一种快速巧妙的方法，也是一种选择自定义大小的方法。

我去这里:

http://vimeo.com/api/v2/video/[VIDEO ID].php

下载文件，打开它，找到640像素宽的缩略图，它的格式如下:

https://i.vimeocdn.com/video/[LONG NUMBER HERE]_640.jpg

你拿这个链接，把640改成——比如——1400，你就会得到这样的东西:

https://i.vimeocdn.com/video/[LONG NUMBER HERE]_1400.jpg

把它粘贴到你的浏览器搜索栏上，享受吧。

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
