Vimeo API - 按质量获取视频的直接 link (C#)

Vimeo API - Getting video's direct link by quality (C#)

我有一个单用户应用程序,

在 Vimeo 的操场上,当做视频/{id} 时,我得到一个很大的 JSON 结果,其中包含:

"files": [
        {
            "quality": "hd",
            "type": "video/mp4",
            "width": 1920,
            "height": 1080,

        },
        {

        },
        {

        {

            "link_secure": "...link..."
        }

(我编辑了网址)

但是在我的代码中执行相同的调用时,整个 "files" 部分都丢失了(整个 json 结果看起来也不同):

这是我的代码,调用:

vc.Request("/videos/255898412", null, "GET");

请求方式:

 public Dictionary<string, object> Request(
            string url,
            Dictionary<string, string> parameters,
            string method,
            bool jsonBody = true)
        { 
            var headers = new WebHeaderCollection()
            {
                { "Authorization", String.Format("Bearer {0}", AccessToken) }
            };
            method = method.ToUpper();
            url = apiRoot + url;
            string body = "";
            string contentType = "application/x-www-form-urlencoded";

            if (parameters != null && parameters.Count > 0)
            {
                if (method == "GET")
                {
                    url += "?" + Helpers.KeyValueToString(parameters);
                }
                else if (method == "POST" || method == "PATCH" || method == "PUT" || method == "DELETE")
                {
                    if (jsonBody)
                    {
                        contentType = "application/json";
                        body = jsonEncode(parameters);
                    }
                    else
                    {
                        body = Helpers.KeyValueToString(parameters);
                    }
                }
            }


            return  JsonConvert.DeserializeObject<Dictionary<string, object>>(Helpers.HTTPFetch(url, method, headers, body, contentType));

        }

我的目标是直接获得 HLS link,以便在我的播放器中播放。 我怎样才能实现它?

谢谢

我今天也遇到了同样的问题

我的笨办法如下

  • 使用3.1版本API

存在一个错误,即使用 API v3.4 的开发人员无法返回下载和文件密钥。 Vimeo 此后修复了该错误(截至 2018 年 2 月 23 日)。

从 API v3.4 开始,开发人员必须使用具有 video_files 范围的令牌对请求进行身份验证,以接收视频响应中的下载​​和文件密钥。

如果您使用 OAuth 工作流程生成令牌,则可以通过这种方式生成具有 video_files 范围的令牌:https://developer.vimeo.com/api/authentication#supported-scopes

希望这些信息对您有所帮助!
