c# - 使用TweetSharp/Hammock将媒体上传到Twitpic时的"Headers rejected by Twitter"

我正在尝试使用WP7应用程序中的TweetSharp和Hammock库将图片上传到Twitpic。上传照片的代码段是这样的:

// Clients.srv is a TweetSharp TwitterClient
RestRequest req = Clients.srv.PrepareEchoRequest();
RestClient client = new RestClient { Authority = "http://api.twitpic.com/", VersionPath = "2" };

req.AddFile("media", e.OriginalFileName, e.ChosenPhoto);
req.AddField("key", "hidden");
req.AddField("message", Tweet.Text);
req.Path = "upload.xml";
req.Method = Hammock.Web.WebMethod.Post;

client.BeginRequest(req, (RestCallback) uploadCompleted);

对代码的一些解释:这来自对photoPickerTask的调用，e是事件参数，其中包含照片名称和文件(IO.Stream对象)。所有这些都已被证明可以正常工作。

问题在于，Twitpic的响应始终是“无法验证您的身份:Twitter拒绝标题”。 TwitterClient正常工作，OAuth token 可以。 API key 正确。我不知道错误是来自我的代码，来自TweetSharp PrepareEchoRequest()函数还是来自Twitpic。有人可以给我一个提示吗？

最佳答案

我今天遇到相同(和类似)的问题已经有很多小时了。我终于通过将版本路径更改为1并将所有 token 输入到请求中来使其工作(如twitpic doco中所述)。我以为昨天尝试过这种精确的组合，但现在可以使用，因此，手指越过api的同时不会更新。

    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;
    }
