尝试调用Twitter流API时出现401错误(401 error while trying to call Twitter stream API)

我对此已经结束了，我已经在这里看了一遍，虽然有类似我的问题已被问到，但我找不到任何答案的确切答案。

我一直试图在C＃控制台应用程序中调用https://stream.twitter.com/1.1/statuses/filter.json几天，并继续获取401 Unauthorized错误，无论我做什么都不会消失。适用于任何不流媒体的东西。

const string streamUrl = "https://stream.twitter.com/1.1/statuses/filter.json"; const string oauth_token = "XXX-XXXXX"; const string oauth_token_secret = "XXXXXXXXXXXX"; const string oauth_consumer_key = "XXXXXXXXXXXXX"; const string oauth_consumer_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // oauth implementation details const string oauth_version = "1.0a"; const string 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(); // create oauth signature const string baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&track=twitter"; var baseString = string.Format(baseFormat, oauth_consumer_key, oauth_nonce, oauth_signature_method, oauth_timestamp, oauth_token, oauth_version); string oauth_signature; var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret), "&", Uri.EscapeDataString(oauth_token_secret)); using (var hasher = new HMACSHA1(Encoding.ASCII.GetBytes(compositeKey))) { oauth_signature = Convert.ToBase64String(hasher.ComputeHash(Encoding.ASCII.GetBytes(baseString))); } // create the request header const string headerFormat = "OAuth oauth_consumer_key=\"{0}\", oauth_nonce=\"{1}\", " + "oauth_signature=\"{2}\", oauth_signature_method=\"{3}\", " + "oauth_timestamp=\"{4}\", oauth_token=\"{5}\", " + "oauth_version=\"{6}\""; var authHeader = string.Format(headerFormat, Uri.EscapeDataString(oauth_consumer_key), Uri.EscapeDataString(oauth_nonce), Uri.EscapeDataString(oauth_signature), Uri.EscapeDataString(oauth_signature_method), Uri.EscapeDataString(oauth_timestamp), Uri.EscapeDataString(oauth_token), Uri.EscapeDataString(oauth_version)); const string postparameters = "track=twitter"; streamUrl = string.Format("{0}?{1}", streamUrl, postparameters); while (true) { var timeLineRequest = (HttpWebRequest)WebRequest.Create(streamUrl); timeLineRequest.Headers.Add("Authorization", authHeader); var encode = System.Text.Encoding.GetEncoding("utf-8"); ServicePointManager.Expect100Continue = false; if (postparameters.Length > 0) { timeLineRequest.Method = "POST"; timeLineRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8"; byte[] _twitterTrack = encode.GetBytes(postparameters); timeLineRequest.ContentLength = _twitterTrack.Length; Stream _twitterPost = timeLineRequest.GetRequestStream(); _twitterPost.Write(_twitterTrack, 0, _twitterTrack.Length); _twitterPost.Close(); } var webResponse = (HttpWebResponse)timeLineRequest.GetResponse(); var responseStream = new StreamReader(webResponse.GetResponseStream(), encode); while (true) { var jsonText = responseStream.ReadLine(); //Success int wait = 250; //Write Status var status = string.Empty; var json = new DataContractJsonSerializer(status.GetType()); byte[] byteArray = Encoding.UTF8.GetBytes(jsonText); var stream = new MemoryStream(byteArray); status = json.ReadObject(stream) as string; Console.Beep(); Console.WriteLine(status); } }

我真的很感激，看看是否还有其他人通过了这个障碍。我厌倦了对此的诅咒。

I'm at my wit's end with this, I have looked all over here and while questions similar to mine have been asked, I can't find this exact one with any answers yet.

I have been trying to call https://stream.twitter.com/1.1/statuses/filter.json from within a C# console app for days now and keep getting at 401 Unauthorized error that no matter what I do won't go away. Works fine for anything not streaming as well.

const string streamUrl = "https://stream.twitter.com/1.1/statuses/filter.json"; const string oauth_token = "XXX-XXXXX"; const string oauth_token_secret = "XXXXXXXXXXXX"; const string oauth_consumer_key = "XXXXXXXXXXXXX"; const string oauth_consumer_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // oauth implementation details const string oauth_version = "1.0a"; const string 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(); // create oauth signature const string baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&track=twitter"; var baseString = string.Format(baseFormat, oauth_consumer_key, oauth_nonce, oauth_signature_method, oauth_timestamp, oauth_token, oauth_version); string oauth_signature; var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret), "&", Uri.EscapeDataString(oauth_token_secret)); using (var hasher = new HMACSHA1(Encoding.ASCII.GetBytes(compositeKey))) { oauth_signature = Convert.ToBase64String(hasher.ComputeHash(Encoding.ASCII.GetBytes(baseString))); } // create the request header const string headerFormat = "OAuth oauth_consumer_key=\"{0}\", oauth_nonce=\"{1}\", " + "oauth_signature=\"{2}\", oauth_signature_method=\"{3}\", " + "oauth_timestamp=\"{4}\", oauth_token=\"{5}\", " + "oauth_version=\"{6}\""; var authHeader = string.Format(headerFormat, Uri.EscapeDataString(oauth_consumer_key), Uri.EscapeDataString(oauth_nonce), Uri.EscapeDataString(oauth_signature), Uri.EscapeDataString(oauth_signature_method), Uri.EscapeDataString(oauth_timestamp), Uri.EscapeDataString(oauth_token), Uri.EscapeDataString(oauth_version)); const string postparameters = "track=twitter"; streamUrl = string.Format("{0}?{1}", streamUrl, postparameters); while (true) { var timeLineRequest = (HttpWebRequest)WebRequest.Create(streamUrl); timeLineRequest.Headers.Add("Authorization", authHeader); var encode = System.Text.Encoding.GetEncoding("utf-8"); ServicePointManager.Expect100Continue = false; if (postparameters.Length > 0) { timeLineRequest.Method = "POST"; timeLineRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8"; byte[] _twitterTrack = encode.GetBytes(postparameters); timeLineRequest.ContentLength = _twitterTrack.Length; Stream _twitterPost = timeLineRequest.GetRequestStream(); _twitterPost.Write(_twitterTrack, 0, _twitterTrack.Length); _twitterPost.Close(); } var webResponse = (HttpWebResponse)timeLineRequest.GetResponse(); var responseStream = new StreamReader(webResponse.GetResponseStream(), encode); while (true) { var jsonText = responseStream.ReadLine(); //Success int wait = 250; //Write Status var status = string.Empty; var json = new DataContractJsonSerializer(status.GetType()); byte[] byteArray = Encoding.UTF8.GetBytes(jsonText); var stream = new MemoryStream(byteArray); status = json.ReadObject(stream) as string; Console.Beep(); Console.WriteLine(status); } }

I would really appreciate to see if anyone else has passed this hurdle. I'm tired of cursing at this.

最满意答案

在计算签名之前，您没有将HTTP方法或基本URL包含在baseString中。这取自Twitter网站：

创建签名基本字符串

到目前为止收集的三个值必须连接成一个字符串，从中生成签名。这被OAuth规范称为签名基本字符串。

要将HTTP方法，基本URL和参数字符串编码为单个字符串：

将HTTP方法转换为大写，并将输出字符串设置为等于此值。

将'＆'字符附加到输出字符串。

百分比对URL进行编码并将其附加到输出字符串。

将'＆'字符附加到输出字符串。

百分比对参数字符串进行编码并将其附加到输出字符串。

You haven't included the HTTP method or the base URL into your baseString before you compute the signature. This is taken from the Twitter site:

Creating the signature base string

The three values collected so far must be joined to make a single string, from which the signature will be generated. This is called the signature base string by the OAuth specification.

To encode the HTTP method, base URL, and parameter string into a single string:

Convert the HTTP Method to uppercase and set the output string equal to this value.

Append the '&' character to the output string.

Percent encode the URL and append it to the output string.

Append the '&' character to the output string.

Percent encode the parameter string and append it to the output string.
