为什么我的电话让Twitter用户时间表返回“401 Unauthorized。”？

我从dev.twitter无耻地获取以下代码来获取特定用户的时间线：

string endpoint = "https://api.twitter.com/1.1/statuses/user_timeline.json"; string user_name = "....."; string ConsumerKey = "...."; string ConsumerSecret = "........"; string Token = "......."; string TokenSecret = "........"; // oauth application keys var oauth_token = Token; var oauth_token_secret = TokenSecret; var oauth_consumer_key = ConsumerKey; var oauth_consumer_secret = ConsumerSecret; // oauth implementation details var oauth_version = "1.0"; var oauth_signature_method = "HMAC-SHA1"; // unique request details var oauth_nonce = Convert.ToBase64String(new ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString())); var timeSpan = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc); var oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString(); var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&screen_name={6}"; var baseString = string.Format(baseFormat, oauth_consumer_key, oauth_nonce, oauth_signature_method, oauth_timestamp, oauth_token, oauth_version, user_name ); //&include_rts=true &exclude_replies=false baseString = string.Concat("GET&", Uri.EscapeDataString(endpoint), "&", Uri.EscapeDataString(baseString)); var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret), "&", Uri.EscapeDataString(oauth_token_secret)); string oauth_signature; using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey))) { oauth_signature = Convert.ToBase64String(hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString))); } string headerFormat = "OAuth oauth_nonce=\"{0}\", oauth_signature_method=\"{1}\", " + "oauth_timestamp=\"{2}\", oauth_consumer_key=\"{3}\", " + "oauth_token=\"{4}\", oauth_signature=\"{5}\", " + "oauth_version=\"{6}\",screen_name=\"{7}\""; var authHeader = string.Format(headerFormat, Uri.EscapeDataString(oauth_nonce), Uri.EscapeDataString(oauth_signature_method), Uri.EscapeDataString(oauth_timestamp), Uri.EscapeDataString(oauth_consumer_key), Uri.EscapeDataString(oauth_token), Uri.EscapeDataString(oauth_signature), Uri.EscapeDataString(oauth_version), Uri.EscapeDataString(user_name) ); // make the request HttpWebRequest request = (HttpWebRequest)WebRequest.Create(endpoint); request.Headers.Add("Authorization", authHeader); request.Method = "GET"; request.ContentType = "application/x-www-form-urlencoded"; var response = (HttpWebResponse)request.GetResponse(); var reader = new StreamReader(response.GetResponseStream()); var objText = reader.ReadToEnd(); 

但是，我在这一行收到401，Unauthorized错误：

 var response = (HttpWebResponse)request.GetResponse(); 

（确实是Twitter开发者线程中的最后几张海报）。

有什么方法可以快速检查我的各种令牌，密钥和秘密是否有效并应该返回我正在寻找的数据？

我在GitHub上创建了一个测试控制台应用程序，它在这里执行此操作：

使用Twitter API 1.1 oAuthvalidation并请求用户的时间表
