我試圖讓我們網站的訪問者將視頻上傳到我們的YouTube頻道。因此，我不想使用OAuth處理身份驗證，否則我需要在任何地方遞交我們的用戶名和密碼。我不想直接上傳，因爲我不想自己託管視頻。使用YouTube API和CORS上傳視頻
因此，我有一個表單收集面板中的一些細節，該按鈕強制回發到創建Video對象的代碼後面並獲取FormUploadToken。然後，我使用這些信息創建一個在頁面上發佈爲文字的信息。
選擇文件，然後點擊上傳按鈕。立即，中止事件被觸發，但沒有理由爲什麼。
任何想法??幫助會非常讚賞：

然後後面的代碼看起來是這樣的：
protected void VideoUploadBttn_Click(object sender, EventArgs e)
{
Video newVideo = new Video();
newVideo.Title = VideoTitleTextBox.Text;
newVideo.Tags.Add(new MediaCategory("Travel", YouTubeNameTable.CategorySchema));
newVideo.Keywords = KeywordsTextBox.Text;
newVideo.Description = VideoDescriptionTextBox.Text;
newVideo.YouTubeEntry.Private = false;
newVideo.Keywords = "Travel";
newVideo.Tags.Add(new MediaCategory("Motorbike", YouTubeNameTable.DeveloperTagSchema));
// alternatively, you could just specify a descriptive string
// newVideo.YouTubeEntry.setYouTubeExtension("location", "Mountain View, CA");
YouTubeRequestSettings settings = new YouTubeRequestSettings(_AppName, _APIKey, _Username, _Password);
YouTubeRequest request = new YouTubeRequest(settings);
FormUploadToken uploadToken = request.CreateFormUploadToken(newVideo);
string actionUrl = uploadToken.Url;
string token = uploadToken.Token;
StringBuilder sb = new StringBuilder();
string url = String.Format("{0}?nexturl={1}", actionUrl, System.Web.HttpUtility.UrlEncode("http://bbc.co.uk"));
sb.AppendFormat("<form name=\"UploadForm\" action=\"{0}\" method =\"post\" enctype=\"multipart/form-data\" >", url);
sb.Append("<input type=\"file\" name=\"file\" id=\"fileToUpload\" onchange=\"fileSelected();\" />");
sb.AppendFormat("<input type=\"hidden\" name=\"token\" value=\"{0}\"/>", token);
sb.Append("<div id=\"fileName\"></div>");
sb.Append("<div id=\"fileSize\"></div>");
sb.Append("<div id=\"fileType\"></div>");
sb.Append("<input type=\"submit\" value=\"Upload\" onclick=\"uploadFile()\" />");
sb.Append("<div id=\"progressNumber\"></div>");
sb.Append("</form>");
Literal2.Text = sb.ToString();
ASPxPanel1.Visible = false;
ASPxPanel2.Visible = true;
}
請不要寫任何系統，允許用戶任意上傳視頻到一個單一的通道。請參閱http://apiblog.youtube.com/2012/02/video-uploads-from-your-sites-community.html –
Jeff，感謝您的評論。那麼，在頻道中看到YouTube視頻的比賽的首選方式是什麼？ – Swomble
好的，所以看了Jeff發來的鏈接，潛在的問題仍然沒有解決。即使將此更改爲使用oAuth並上傳到用戶自己的頻道而不是我們的，也不能解釋爲什麼立即中止上傳 – Swomble
