twitter request_token 401 unauthorized

ok after two days of tryouts i still cant my titanium application to play well with twitter request_token api 1.1, i am always getting 401 unauthorized error .below is my code. i am blocked so any help is appreciated.

var httpClient = Ti.Network.createHTTPClient({
                onerror : function(e) {
                    alert(this.status + ":" + e.error);
                },
                onload : function(e) {
                    alert(this.responseText);
                    if (this.readyState == 4) {
                        var resposeText = this.responseText;
                    }

                }
            });
httpClient.open('POST', "https://api.twitter.com/oauth/request_token");
httpClient.setRequestHeader("content-type", "application/x-www-form-urlencoded; charset=UTF-8");

var now = new Date().getTime();

var chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
var nonce = "";
for (var i = 0; i < 10; ++i) {
    var rnum = Math.floor(Math.random() * chars.length);
    nonce += chars.substring(rnum, rnum + 1);
}
var parameters = "oauth_callback=" + Ti.Network.encodeURIComponent("http://apicallback.stc.com.sa");

var signature = "POST&" + Ti.Network.encodeURIComponent("https://api.twitter.com/oauth/request_token") + "&" + Ti.Network.encodeURIComponent(parameters);
var header = "OAuth oauth_callback=\"" + Ti.Network.encodeURIComponent("http://apicallback.stc.com.sa") + "\",oauth_consumer_key=\"wPdlchopdYaqHhab8H8jMA\",oauth_nonce=\"" + nonce + "\",oauth_signature=\"" + signature + "\",oauth_signature_method=\"HMAC-SHA1\",oauth_timestamp=\"" + now + "\",oauth_version=\"1.0\"";
httpClient.setRequestHeader("Authorization", header);
httpClient.send(parameters);

There are multiple twitter libraries out there for appcelerator that already work, I would suggest starting with one of them.

There were several errors :

  • Your nonce seems to be built incorrectly. Generate a string with 32 letters and encode it with Base 64.
  • Your signature is not built correctly too. Refer to the Twitter Developers documentation about making signatures. Here are your errors :
    • All the OAuth arguments are missing but oauth_callback. The OAuth arguments which are used in the Authorize header have to be included in the parameters for the signature
    • You do not build the key to sign datas.
    • You do not use the signature method (oauth_signature_method which is set to "HMAC-SHA1") to sign your datas.

  • Your timestamp is too big. It is the number of seconds since the Unix Epoch time, not the milliseconds. Add a "/1000" :

    var now = new Date().getTime() / 1000

More generally have a look at Twitter Developers documentation about authorizing requests : https://dev.twitter.com/docs/auth/authorizing-request
