将评论添加到youtube视频

Question

我的网页是在.net中开发的，我正尝试使用以下代码向YouTube视频添加评论。

 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); 
     } 
    } 

该代码执行时没有任何错误。如果我使用“myusername”&“mypassword”登录，它也发布评论。

但是，如果我用它给我下面的错误任何其他用户登录： ë

Execution of request failed:

我已经为此工作了很多。我不确定这里有什么问题。任何帮助，将不胜感激。

看起来您正在使用ClientLogin，它已弃用且可能无法正常工作。请考虑使用OAuth2，这里是一个例子：http://code.google.com/p/google-gdata/source/browse/trunk/clients/cs/samples/oauth2_sample/oauth2demo.cs。此外，YouTube会拒绝某些评论，尝试使用不带特殊字符的简单字符串。
