I'm trying for many days to make it work for an iPhone App that I'm developing with Titanium Appcelerator. I'm getting a a 401 error at every attempt. I'm basically using a HMAC-SHA1 js library that might be faulty. I checked in many samples on this list that most of the signatures are ending by "%3D" and mine is never ending by those characters.
Here's one of my signature base string and header assuming that XXXX and XX________XX are masqued values for the purpose of this post signature base string : POST&https%3A%2F%2Fapi.twitter.com%2Foauth%2Faccess_token&oauth_consumer_key%3XX________XX%26oauth_nonce%3D1274444947%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1274444946%26oauth_version%3D1.0%26x_auth_mode%3Dclient_auth%26x_auth_password%3DXXXX%26x_auth_username%3DXXXX headers : 'POST','https://api.twitter.com/oauth/access_token' 'Content-Type', 'application/x-www-form-urlencoded' 'Authorization', OAuth oauth_nonce="1274438928", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1274438926", oauth_consumer_key="XX________XX", oauth_signature="pfACjg1vlhpuIa9esoL4v14ATOQ", oauth_version="1.0" Data : x_auth_username=XXXX&x_auth_password=XXXX&x_auth_mode=client_auth Any help much apreciated Michel Perrin
