【问题描述】：

我对 SendTweetWithMedia() 有疑问。这是我的实现方式

        var service = new TwitterService(TwitterSettings.ConsumerKey, TwitterSettings.ConsumerSecret);
        service.AuthenticateWith(twitterAccess.AccessToken, twitterAccess.AccessTokenSecret);

        string status = string.IsNullOrEmpty(message) ? " " : message;
        var memoryStream = new MemoryStream();
        bitmap.SaveJpeg(memoryStream, bitmap.PixelWidth, bitmap.PixelHeight, 0, 100);
        memoryStream.Position = 0;

        var options = new SendTweetWithMediaOptions
        {
            Status = status,
            Images = new Dictionary<string, Stream> {{"picture", memoryStream}}
        };
        service.SendTweetWithMedia(options, (responseStatus, response) => Dispatcher.BeginInvoke(() =>
        {
            memoryStream.Close();
            memoryStream.Dispose();

            if (response.StatusCode == HttpStatusCode.OK)
            {
                UiHelper.ShowToastPrompt(AppResources.TwitterToastPrompt);
            }
            else if (response.StatusCode == HttpStatusCode.Unauthorized)
            {
                NavigationService.Navigate(new Uri("/TwitterLoginPage.xaml", UriKind.Relative));
            }
            else
            {
                MessageBox.Show(response.StatusDescription, AppResources.ErrorMessageBoxCaption, MessageBoxButton.OK);
            }
        }));

但它在消息框中显示“禁止”。

即使我尝试从 SendTweetWithMediaOptions 中删除图像，但它没有帮助。

有人可以帮忙吗？谢谢。

【解决方案1】：

我终于可以使用 TweetSharp + Hammock 和此代码将照片上传到 Twitter

TwitterService service = new TwitterService(consumerKey, consumerSecret);
service.AuthenticateWith(accessToken, accessTokenSecret);

if (thumbnail != null)  // an image post - go through twitpic
{
    MemoryStream ms = new MemoryStream();
    thumbnail.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
    ms.Seek(0, SeekOrigin.Begin);

    // Prepare an OAuth Echo request to TwitPic
    RestRequest request = service.PrepareEchoRequest();
    request.Path = "uploadAndPost.xml";
    request.AddField("key", twitpicApiKey);
    request.AddField("consumer_token", consumerKey);
    request.AddField("consumer_secret", consumerSecret);
    request.AddField("oauth_token", accessToken);
    request.AddField("oauth_secret", accessTokenSecret);
    request.AddField("message", "Failwhale!");
    request.AddFile("media", "failwhale" + Environment.TickCount.ToString(), ms, "image/jpeg");

    // Post photo to TwitPic with Hammock
    RestClient client = new RestClient { Authority = "http://api.twitpic.com/", VersionPath = "1" };
    RestResponse response = client.Request(request);

    return response.Content;
}

将 VersionPath 的值设置为 1 非常重要。我之前用过2，但是没用。
