Hi Team,
Tweet working fine when i use SDK for posting (var options = new SendTweetWithMediaOptions()
But when i initiate the post via Webrequest . i am getting 401 unauthorized issue . Coding i have metioned below .
resource_url = “https://api.twitter.com/1.1/statuses/update.json?status=TestPost”;
var oauthToken = "3xxxxx7";
var oauthTokenSecret = "vtzxxxxx36";
var oauthConsumerKey = "LjUxxxxxkHL6";// = "insert here...";
var oauthConsumerSecret = "6nxxxxxFR";// = "insert here...";
// oauth implementation details
var oauth_version = "1.0";
var oauth_signature_method = "HMAC-SHA1";
// unique request details
var oauthNonce = 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 oauthTimestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString();
// 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}&q={6}";
var baseString = string.Format(baseFormat,
oauthConsumerKey,
oauthNonce,
oauth_signature_method,
oauthTimestamp,
oauthToken,
oauth_version,
Uri.EscapeDataString(screenName)
);
baseString = string.Concat("POST&", Uri.EscapeDataString(resource_url), "&", Uri.EscapeDataString(baseString));
var compositeKey = string.Concat(Uri.EscapeDataString(oauthConsumerSecret),
"&", Uri.EscapeDataString(oauthTokenSecret));
string oauthSignature;
using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey)))
{
oauthSignature = Convert.ToBase64String(
hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString)));
}
// create the request header
var 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}\"";
var authHeader = string.Format(headerFormat,
Uri.EscapeDataString(oauthNonce),
Uri.EscapeDataString(oauth_signature_method),
Uri.EscapeDataString(oauthTimestamp),
Uri.EscapeDataString(oauthConsumerKey),
Uri.EscapeDataString(oauthToken),
Uri.EscapeDataString(oauthSignature),
Uri.EscapeDataString(oauth_version)
);
ServicePointManager.Expect100Continue = false;
// make the request
var postBody = "status=" + Uri.EscapeDataString(screenName);//
// resource_url += "?" + postBody;
// resource_url += "&" + postBody;
HttpWebRequest request
= System.Net.WebRequest.Create(resource_url) as HttpWebRequest;
request.Headers.Add("Authorization", authHeader);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
var response = request.GetRequestStream();
byte[] dsd = ASCIIEncoding.ASCII.GetBytes(postBody);
response.Write(dsd, 0, dsd.Length);
WebResponse Getresponsetweet = request.GetResponse();
Please advice me how to solve this ?
Since i am going to integrate Ads Api .i need to follow web request only .
Thanks
