Twitter OAuth error 32 (401) using Unirest Java -


i using unirest build http request:

httprequestwithbody request = unirest                 .post("https://api.twitter.com/1.1/statuses/update.json")                 .header("authorization", oauth)                 .header("content-type", "application/x-www-form-urlencodedheader")                 .querystring("status", "123testtest");

so far can't see issues this. maybe problem in creating oauth signature?

private string percentencode(long toencode) {     try {         string returnstring = urlencoder.encode(toencode.tostring(), "utf-8");         return returnstring.replace("+", "%20");     } catch (unsupportedencodingexception e) {         return "";     } }  private string percentencode(string toencode) {     try {         string returnstring = urlencoder.encode(toencode, "utf-8");         return returnstring.replace("+", "%20");     } catch (unsupportedencodingexception e) {         return "";     } }  private string generatenonce() {     string nonce = "";     string possible = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789";     (int = 0; < 45; i++) {         nonce += possible.charat((int) math.floor(math.random() * possible.length()));     }     return nonce; }  public string buildheader() throws unsupportedencodingexception {     string parameter_string = "";     string nonce = generatenonce();     parameter_string += "include_entities=true";     parameter_string += "&oauth_consumer_key=" + percentencode(consumerkey);     parameter_string += "&oauth_nonce=" + percentencode(nonce);     parameter_string += "&oauth_signature_method=hmac-sha1";     parameter_string += "&oauth_status=" + percentencode("123testtest");     parameter_string += "&oauth_timestamp=" + percentencode(instant.now().getepochsecond());     parameter_string += "&oauth_token=" + percentencode(accessstoken);     parameter_string += "&oauth_version=1.0";      string signature_base_string = "";     signature_base_string += percentencode("post");     signature_base_string += '&' + percentencode(postapiurl);     signature_base_string += '&' + percentencode(parameter_string);      string signing_key = percentencode(this.consumersecret) + '&'             + percentencode(this.accesstokensecret);     byte[] hmac_signature_bytes = hmacutils.hmacsha1(signing_key, signature_base_string);     string hmac_signature = new string(base64.getencoder().encode(hmac_signature_bytes));      string oauthstring = "oauth ";     oauthstring += "oauth_consumer_key=\"" + percentencode(consumerkey) + '"';     oauthstring += ", oauth_nonce=\"" + percentencode(nonce) + '"';     oauthstring += ", oauth_signature=\"" + percentencode(hmac_signature) + '"';     oauthstring += ", oauth_signature_method=\"hmac-sha1\"";     oauthstring += ", oauth_timestamp=\"" + percentencode(instant.now().getepochsecond()) + '"';     oauthstring += ", oauth_token=\"" + percentencode(accessstoken) + '"';     oauthstring += ", oauth_version=\"1.0\"";     return oauthstring; }

i'd thankful advice, lost. authorization header looks in http request:

oauth oauth_consumer_key="xxx", oauth_nonce="xxx", oauth_signature="xxx", oauth_signature_method="hmac-sha1", oauth_timestamp="1478367183", oauth_token="xxx", oauth_version="1.0"

this response server:

[18:33:03]: {"errors":[{"code":32,"message":"could not authenticate you."}]} [18:33:03]: 401
