问题描述
我正在使用youtube的.NET API检索视频供稿，下面是代码:
I am using youtube's .NET API to retrieve video feeds, here is the code:
String[] ids;
YouTubeRequestSettings settings = new YouTubeRequestSettings("My App Name", "My App Key");
YouTubeRequest request = new YouTubeRequest(settings);
Uri uri =
new Uri("http://gdata.youtube.com/feeds/api/users/nptelhrd/uploads?max-results=50");//Change "GoogleDevelopers" to "default"
Google.GData.Client.Feed<Video> videoFeed = request.Get<Video>(uri);
ids = new String[videoFeed.TotalResults];
int count = 0;
for (int i = 0; i < 50; i++)
ids[i] = videoFeed.Entries.ElementAt(i).VideoId;
for (int i = 50; i < ids.Length-50; i+=50)
{
Uri uri2 =
new Uri("http://gdata.youtube.com/feeds/api/users/nptelhrd/uploads?max-results=50&start-index=" + i.ToString());//Change "GoogleDevelopers" to "default"
Google.GData.Client.Feed<Video> videoFeed2 = request.Get<Video>(uri);
for (int j = 0; j < 50; j++)
{
ids[i+j] = videoFeed2.Entries.ElementAt(j).VideoId;
count++;
}
}
上面的代码返回用户"nptelhrd"上传的每个视频的所有信息(标题，描述，ViewCount，评分等).该特定用户上传了6950个视频.
The above code returns every information(Title, Description, ViewCount, Rating....etc.) for each video uploaded by the user "nptelhrd". There are 6950 videos uploaded by this particular user.
以上代码在512Kbps连接上需要15分钟来执行，因为它检索每个视频的所有信息非常缓慢，浪费了大量服务器资源.上面的代码不能修改为仅检索videoId吗?如何只检索所有视频的videoId?
THE ABOVE CODE TAKES 15 MINUTES TO EXECUTE on a 512Kbps connection, because it retrieves all information of each and every video, its painfully slow, wastes a lot of server resources. Can't the above code be modified so that it only retrieve videoId's? How can I only retrieve videoId's of all videos?
推荐答案
由于.NET YOUTUBE API的当前限制，无法仅检索VIDEOID.
With the present limitations of .NET YOUTUBE API, its not possible to retrieve only VIDEOID.
