Hello I am trying to post reply against status but it throwing “The remote server returned an error: (401) Unauthorized.” error. My code is working fine if I post a new status.
Here is my code:
private string PostTwitterMessage(string message)
{
var token = "MyToken";
var token_secret = "Token_secret";
var oauth_consumer_key = "Key";
var oauth_consumer_secret = "secret";
string PostID = string.Empty;
try
{
// oauth application keys
var oauth_token = token;
var oauth_token_secret = token_secret;
// 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();
// message api details
var status = message;
var resource_url = "https://api.twitter.com/1.1/statuses/update.json";
// create oauth signature
var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
"&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&status={6}";
var baseString = string.Format(baseFormat,
oauth_consumer_key,
oauth_nonce,
oauth_signature_method,
oauth_timestamp,
oauth_token,
oauth_version,
Uri.EscapeDataString(status)
);
baseString = string.Concat("POST&", Uri.EscapeDataString(resource_url), "&", Uri.EscapeDataString("in_reply_to_status_id=346397028374425602"), "&", 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)));
}
// create the request header
var 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)
);
// make the request
var postBody = "status=" + Uri.EscapeDataString(status) + "&" + "in_reply_to_status_id=" + Uri.EscapeDataString("346397028374425602");
ServicePointManager.Expect100Continue = false;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url);
request.Headers.Add("Authorization", authHeader);
request.Method = "POST";
request.Timeout = 120000;
request.ContentType = "application/x-www-form-urlencoded";
using (Stream stream = request.GetRequestStream())
{
byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);
stream.Write(content, 0, content.Length);
}
var response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode != HttpStatusCode.OK)
Console.WriteLine("There's been a problem trying to tweet:" +
Environment.NewLine +
response.StatusDescription);
else
{
PostID = "Successful";
}
}
catch (Exception exp)
{
return exp.Message;
}
return PostID;
}
This code runs fine if i not include reply Id with it. I post my message start with @ScreenName.
Regards
