I can call https://api.twitter.com/oauth/access_token get oauth_token.
But I try to call https://api.twitter.com/1.1/users/show.json, always get
{"errors":[{"code":32,"message":"Could not authenticate you."}]}
following is my code:
base string:
GET&https%3A%2F%2Fapi.twitter.com%2F1.1%2Fusers%2Fshow.json&oauth_consumer_key%3DTTxxxxxxxxxnHbK%26oauth_nonce%3D243720839%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1439373646%26oauth_token%3D7009042-PGexxxxxxxx21HkwyaGdYjQCrFz%26oauth_version%3D1.0%26user_id%3D7009042
authorization header:
oauth_consumer_key="TTQuxxxxxxxxknHbK", oauth_nonce="243720839", oauth_signature="QY%2Ft9TYeAw%2FvfXoxe5nKVk2NHF4%3D", oauth_signature_method ="HMAC-SHA1", oauth_timestamp="1439373646", oauth_token="7009042-xxxxxxxxxxxaGdYjQCrFz", oauth_version="1.0"
source code:
String TwitterUrl = "https://api.twitter.com/1.1/users/show.json";
string timeStamp = GetTimeStamp();
string nonce = GetNonce();
String SigBaseStringParams = "oauth_consumer_key=" + ConsumerKey;
SigBaseStringParams += "&" + "oauth_nonce=" + nonce;
SigBaseStringParams += "&" + "oauth_signature_method=HMAC-SHA1";
SigBaseStringParams += "&" + "oauth_timestamp=" + timeStamp;
SigBaseStringParams += "&" + "oauth_token=" + user.oauth_token;
SigBaseStringParams += "&" + "oauth_version=1.0";
//SigBaseStringParams += "&" + "screen_name=" + user.screen_name;
SigBaseStringParams += "&" + "user_id=" + user.user_id;
String SigBaseString = "GET&";
SigBaseString += Uri.EscapeDataString(TwitterUrl) + "&" + Uri.EscapeDataString(SigBaseStringParams); ;
String Signature = GetSignature(SigBaseString, ConsumerSecret);
string authorizationHeaderParams = "oauth_consumer_key=\"" + ConsumerKey + "\", oauth_nonce=\"" + nonce +
"\", oauth_signature=\"" + Uri.EscapeDataString(Signature) + "\", oauth_signature_method =\"HMAC-SHA1\"" +
", oauth_timestamp=\"" + timeStamp + "\", oauth_token=\"" + Uri.EscapeDataString(user.oauth_token) + "\", oauth_version=\"1.0\"";
HttpClient httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Authorization = new HttpCredentialsHeaderValue("OAuth", authorizationHeaderParams);
var result = await httpClient.GetAsync(new Uri(TwitterUrl));
var content = await result.Content.ReadAsStringAsync();
How can I solve the problem? thank you.
