通过 google api 将视频上传到 youtube 服务器时出错

Question

这是我的代码

上传视频大小 7Mb

上传视频类型 mp4

category.SelectedItem.Text：视频/mp4

如果 (FileUpload1.PostedFile != null)
{

        HttpPostedFile postfiles = FileUpload1.PostedFile;
        if (postfiles.ContentLength > 0)
        {
            System.IO.Stream iStream = postfiles.InputStream;
            byte[] filedata = new byte[postfiles.ContentLength];
            iStream.Read(filedata, 0, postfiles.ContentLength);
            postfiles.SaveAs(@"c:\Temp\" + postfiles.FileName);
            YouTubeRequestSettings settings = new YouTubeRequestSettings("AAA", youtube_DVkey, g_username, g_password);
            YouTubeRequest request = new YouTubeRequest(settings);
            Video newvideo = new Video();
            newvideo.Title = txtTitle.Text;
            newvideo.Tags.Add(new MediaCategory(category.SelectedItem.Text, YouTubeNameTable.CategorySchema));
            newvideo.Keywords = txtKeywords.Text;
            newvideo.Description = txtDescription.Text;
            newvideo.Private = false;
            newvideo.Tags.Add(new MediaCategory(txtTitle.Text.Trim(), YouTubeNameTable.DeveloperTagSchema));
            newvideo.YouTubeEntry.Location = new Google.GData.Extensions.Location.GeoRssWhere(37, -122);
            newvideo.YouTubeEntry.MediaSource = new MediaFileSource(@"c:\Temp\" + postfiles.FileName, Video_type.SelectedItem.Text);
            try
            {
                Video result_video = request.Upload(youtubeaccount, newvideo);
                File.Delete(@"c:\Temp\" + postfiles.FileName);
                Response.Redirect("gallery.aspx");

            }
            catch (Google.GData.Client.GDataRequestException ex)
            {
                Response.Write(ex.ToString());
            }
            catch (Google.GData.Client.InvalidCredentialsException ex)
            {
                Response.Write("Invalid credentials" + ex.ToString());
            }
            catch(Exception ex)
            {
                Response.Write("Failed to upload！" + ex);
            }
        }
    }

例外

您必须使用resumable upload mechanism 来上传大文件。使用 ResumableUploader 组件检查 YouTubeUploader 源以获取完整示例：
