我正在尝试使用v2 API开发一个与Tumblr交互的简单应用程序.我能够通过oAuth流程中的每一步(感谢Twitter上的文档)并获得授权和认证的令牌和秘密.但是在发布时,我收到了401未经授权的错误.这是相关的代码段:

    private void post_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        url = new Uri("http://api.tumblr.com/v2/blog/*myblog*.tumblr.com/post");

        Random random = new Random();
        nonce = random.Next(1234000, 9999999).ToString();

        TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0);
        timestamp = Convert.ToInt64(ts.TotalSeconds).ToString();

        string method = "POST";

        StringBuilder sb = new StringBuilder();
        sb.AppendFormat("{0}&", method);
        sb.AppendFormat("{0}&", upperCaseUrl(HttpUtility.UrlEncode(url.ToString())));
        sb.AppendFormat("body%3D{0}%26", upperCaseUrl(HttpUtility.UrlEncode(textBox.Text)));
        sb.AppendFormat("oauth_consumer_key%3D{0}%26", consumerKey);
        sb.AppendFormat("oauth_nonce%3D{0}%26", nonce);
        sb.AppendFormat("oauth_signature_method%3D{0}%26", "HMAC-SHA1");
        sb.AppendFormat("oauth_timestamp%3D{0}%26", timestamp);
        sb.AppendFormat("oauth_token%3D{0}%26", token);
        sb.AppendFormat("oauth_version%3D{0}%26", "1.0");
        sb.AppendFormat("type%3D{0}", "text");

        System.Diagnostics.Debug.WriteLine(sb.ToString());

        string signingKey = consumerSecret + '&' + secret;

        HMACSHA1 signing = new …
