为优酷视频添加评论

Question

我的网页是用.net开发的，我正在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);
        }
    }

此代码执行时没有任何错误。如果我使用"myusername"和"mypassword"登录，它也会发表评论。

但是，如果我使用任何其他用户登录，它会给我以下错误：E

Execution of request failed:

我在这方面做了很多工作。我不确定这里有什么问题。任何帮助将不胜感激。

看起来您正在使用已弃用且可能无法正常工作的 ClientLogin。请考虑改用OAuth2，下面是一个示例：http://code.google.com/p/google-gdata/source/browse/trunk/clients/cs/samples/oauth2_sample/oauth2demo.cs。此外，YouTube将拒绝某些评论，请尝试使用没有特殊字符的简单字符串。
