Hi guys, Sorry for troubling you with yet *another* "Failed to validate oauth signature and token" error, but I just can't figure out what's wrong with my request.
I'm constructing my signature from this string: POST&http%3A%2F%2Fapi.twitter.com%2Foauth %2Frequest_token&oauth_callback%3Dhttp%3A%2F%2Fcraiga.id.au%2Ftwitter %2Fconnected%26oauth_consumer_key%3Dtm5...DOg%26oauth_nonce%3D8...22b %26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp %3D1275453048%26oauth_version%3D1.0 >From this I generate a 28 character signature using the following PHP code: base64_encode(hash_hmac('sha1', $raw, 'YUo...HIU' . '&', true)); Using this signature, I send the following request: POST http://api.twitter.com/oauth/request_token HTTP/1.1 Host: api.twitter.com Pragma: no-cache Accept: */* Proxy-Connection: Keep-Alive Authorization: OAuth oauth_nonce="3D8...22b", oauth_callback="http%3A %2F%2Fcraiga.id.au%2Ftwitter%2Fconnected", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1275453048", oauth_consumer_key="tm5...DOg", oauth_signature="aYd...c6E%3D", oauth_version="1.0" Content-Length: 266 Content-Type: application/x-www-form-urlencoded oauth_callback=http%3A%2F%2Fcraiga.id.au%2Ftwitter %2Fconnected&oauth_consumer_key=tm5...DOg&oauth_nonce=3D8...22b&oauth_signature_method=HMAC- SHA1&oauth_timestamp= 1275453048&oauth_version=1.0 I get the following response from Twitter to this request: HTTP/1.1 401 Unauthorized Date: Wed, 02 Jun 2010 04:40:14 GMT Server: hi Status: 401 Unauthorized X-Transaction: 1275453614-48409-7443 Last-Modified: Wed, 02 Jun 2010 04:40:14 GMT X-Runtime: 0.01083 Content-Type: text/html; charset=utf-8 Content-Length: 44 Pragma: no-cache X-Revision: DEV Expires: Tue, 31 Mar 1981 05:00:00 GMT Cache-Control: no-cache, no-store, must-revalidate, pre-check=0, post- check=0 Set-Cookie: k=58.161.42.101.1275453614748615; path=/; expires=Wed, 09- Jun-10 04:40:14 GMT; domain=.twitter.com Set-Cookie: guest_id=12754536147577949; path=/; expires=Fri, 02 Jul 2010 04:40:14 GMT Set-Cookie: _twitter_sess=BAh7CToPY3JlYXRlZF9hdGwrCKaq9fYoAToRdHJhbnNfcHJvbXB0MDoHaWQi %250AJWU0ZDFhMGQzMWU0NTZjMzJiZWFkNWUzMTA4ZDRjOTg3IgpmbGFzaElDOidB %250AY3Rpb25Db250cm9sbGVyOjpGbGFzaDo6Rmxhc2hIYXNoewAGOgpAdXNlZHsA-- f1e5c7649858a1694f24307504354846bbc1d16b; domain=.twitter.com; path=/ Vary: Accept-Encoding Connection: close Failed to validate oauth signature and token If anyone can cast any light on why this might be failing, I'd love to hear.
