Signature not working correctly.

[Tarokan]

I have the following code to communicate with the FatSecret API which uses OAuth 1.0.

`
describe('OAuth1.0',function(){
var OAuth = require('oauth');

it('tests FatSecret API',function(done){
var oauth = new OAuth.OAuth(
null,
null,
CONSUMER_KEY,
CONSUMER_SECRET,
'1.0',
null,
'HMAC-SHA1',
32
);
oauth.get(
'http://platform.fatsecret.com/rest/server.api',
PROFILE_TOKEN, //test user token
PROFILE_SECRET, //test user secret
function (e, data, res){
if (e) console.error(e);
console.log(require('util').inspect(data));
done();
});
});
});
`

I'm getting this response:
<?xml version="1.0" encoding="utf-8" ?>\r\n<error xmlns="http://platform.fatsecret.com/api/1.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://platform.fatsecret.com/api/1.0/ http://platform.fatsecret.com/api/1.0/fatsecret.xsd">\r\n\t<code>2</code>\r\n\t<message>Missing required oauth parameter: oauth_signature_method</message>\r\n</error>\r\n
