Hi,
Im trying to implement OAuth using JavaScript, but when I make my request to http://api.twitter.com/oauth/request_token I am getting the above message in the response ("failed to validate oauth signature and token").
As far as I can tell I'm including all the correct parameters, both in the encoding of the signature base:
basestring: (consumer key removed for security)
POST&http%3A%2F%2Ftwitter.com%2Foauth%2Frequest_token%26oauth_callback %3Doob%26oauth_consumer_key %3D11111111111111111111112222222222222%26oauth_nonce %3DO3cHsSXrfnzT%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp %3D1275928008%26oauth_version%3D1.0
consumer secret: (removed for security)
11111111111111111111112222222222222&
Signature:
R3eHMuQ04F37+xPJSIsoo0aMzc8
Post Data: (consumer key removed for security)
oauth_callback=oob&oauth_consumer_key=11111111111111111111112222222222222&oauth_signature_method=HMAC-SHA1&oauth_signature=pjDh8jkp89ThBtzzB9dQmxQfcg&oauth_timestamp=1275928413&oauth_nonce=qyq3Jhn8rtTZ&oauth_version=1.0
And I've checked that the clock is correct on my device as that's the only real result I can find for this problem :( The nonce is unique and generated every time it runs... Unfortunately I don't know where to look now. I can't spot anything obvious. I've re-written the entire request twice - once using the oauth.js library and once completely manually, but in both cases it fails with the same error!
Any suggestions?
Cheers
