將評論添加到youtube視頻

Question

我的網頁是在.net中開發的，我正嘗試使用以下代碼向YouTube視頻添加評論。

 string lsDeveloperKey = "myDeveloperKey"; 

    //This will ask user to login to accounts.google for posting comment 
     if (!Request.QueryString.AllKeys.Contains("token")) 
     { 
      string lsUserName = "myusername"; 
      string lsPassword = "mypassword"; 

      YouTubeRequestSettings loSettings = new YouTubeRequestSettings(Keys.PortalName, lsDeveloperKey, lsUserName, lsPassword); 
      YouTubeRequest loRequest = new YouTubeRequest(loSettings); 

      Uri videoEntryUrl = new Uri(string.Format("{0}/{1}", Google.GData.YouTube.YouTubeQuery.DefaultVideoUri, "ofjQ_Gf5CQc")); 
      Google.YouTube.Video loVideo = loRequest.Retrieve<Google.YouTube.Video>(videoEntryUrl); 

      string lsRandomVideoId = getRandomId() + loVideo.VideoId; 
      Session[lsRandomVideoId] = loVideo; ; 

      Response.Redirect(AuthSubUtil.getRequestUrl(Request.Url.ToString() + "?v=" + lsRandomVideoId, "http://gdata.youtube.com", false, true)); 
     } 

    //This will post a comment for logged user 
     else 
     { 
      Session["token"] = AuthSubUtil.exchangeForSessionToken(Request.QueryString["token"], null).ToString(); 

      YouTubeRequestSettings loSettings = new YouTubeRequestSettings(Keys.PortalName, lsDeveloperKey, (String)   Session["token"]); 
      YouTubeRequest loRequest = new YouTubeRequest(loSettings); 

      Video loVideo = (Video)Session[Request.QueryString["v"]]; 

      Comment loComment = new Comment(); 
      loComment.Content = "This is my comment from my app"; 
      loRequest.AddComment(loVideo, loComment); 
     } 
    } 

該代碼執行時沒有任何錯誤。如果我使用「myusername」&「mypassword」登錄，它也發佈評論。

但是，如果我用它給我下面的錯誤任何其他用戶登錄： ë

Execution of request failed:

我已經爲此工作了很多。我不確定這裏有什麼問題。任何幫助，將不勝感激。

看起來您正在使用ClientLogin，它已棄用且可能無法正常工作。請考慮使用OAuth2，這裏是一個例子：http://code.google.com/p/google-gdata/source/browse/trunk/clients/cs/samples/oauth2_sample/oauth2demo.cs。此外，YouTube會拒絕某些評論，嘗試使用不帶特殊字符的簡單字符串。
