Object # has no method 'getOAuthAccessToken'

[shamod]

I keep getting the error above on callback.

Any idea why?

I think its probably related to: #39 .. ARe you using express 2 ?

Ah sorry I was concerned that you might be (i.e. that could be what was causing the issue!) Can you put your code somewhere ?

I have two files: app.js and oauth_controller.js

it works fine while retrieving the request toke and secret.

it fails when trying to call getOAuthAccessToken from app.js by calling oauthController.getOAuthTokenAndSecret.

thanks for your kind help.

*** app.js:

var express = require('express');

var app = module.exports = express.createServer();

var memStore = require('connect').session.MemoryStore;

var oauthController = require('./controllers/oauth_controller');

// Configuration
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.compiler({ src: __dirname + '/public', enable: ['less'] }));
app.use(express.static(__dirname + '/public'));
app.use(express.cookieParser());
app.use(express.session({secret: 'secret', store: memStore({
reapInterval: 60000 * 10
})}));
app.use(app.router);
});

app.get('/user/new', function(req, res) {
oauthController.getRequestTokenForAuhtorization(function(error, oa, request_token, request_token_secret, url) {
if(error) {
sys.log(JSON.stringify(error));
} else {
req.session.oa = oa;
req.session.request_token = request_token;
req.session.request_token_secret = request_token_secret;
res.render('user/new', {locals: {
user: req.body && req.body.user,
twitterUrl: url
}
});
}
});
});

app.get('/user/oauth', function(req, res) {
if(req.session.request_token) {

*** Fails here --> oauthController.getOAuthTokenAndSecret(req.session.oa, 
                       req.session.request_token, 
                       req.session.request_token_secret, 
                       req.param('oauth_verifier'),
                       function(error, oauth_access_token, oauth_access_token_secret) {
                         if(error) {
            sys.log(JSON.stringify(error));
                         } else {
                           res.render('user/new', {locals: {
                 user: req.body && req.body.user
                }
                   });
                         }
                       }
                     );
} else {
  sys.log('callback oauth url error');
}

});

*** oauth_controller.js:

var OAuth = require('oauth').OAuth;
var sys = require('sys');

exports.getRequestTokenForAuhtorization = function(callback) {

var consumer_key = some_key,
consumer_secret = some_secret,
request_token_url = 'https://api.twitter.com/oauth/request_token',
access_token_url = 'https://api.twitter.com/oauth/access_token',
authorize_url = 'https://api.twitter.com/oauth/authorize?oauth_token=',
oauth_version = '1.0',
callback_url = 'http://localhost:3000/user/oauth',
encryption_type = 'HMAC-SHA1';

var oa = new OAuth(request_token_url, access_token_url, consumer_key, consumer_secret,
oauth_version, callback_url, encryption_type);

oa.getOAuthRequestToken(function(error, request_token, request_token_secret, results) {
if(error) {
callback(error, null, null, null, null);
} else {
var url = authorize_url + request_token;
callback(null, oa, request_token, request_token_secret, url);
}
});
};

exports.getOAuthTokenAndSecret = function(oa, request_token, request_token_secret, oauth_verifier, callback) {
oa.getOAuthAccessToken(request_token, request_token_secret, oauth_verifier,
function(error, oauth_access_token, oauth_access_token_secret, results) {
if(error) {
callback(error, null, null);
} else {
sys.log("oauth_access_token: " + oauth_access_token);
sys.log("oauth_access_token_secret: " + oauth_access_token_secret);
callback(null, oauth_access_token, oauth_access_token_secret);
}
}
);
};

Hmmm I've only just noticed which project this issue is against, have you seen http://github.com/ciaranj/connect-auth I've got a (working!) implementation of a Twitter authentication system in there, that would almost certainly be a good place to look for clues (if not used!)

[ciaranj]

When you inspect the 'oauthController' (console.log) what methods are on that object. I don't think this is a node-oauth issue, more an express thing ... strange.

[shamod]

when i inspect oauthController, i see all methods in there. it is really this method that fails

oa.getOAuthAccessToken(request_token, request_token_secret, oauth_verifier,
function(error, oauth_access_token, oauth_access_token_secret, results)

wierd thing is oa.getOAuthRequestToken works with no issue but not oa.getOAuthAccessToken.

how is this possible? after it fails at oa.getOAuthAccessToken, one thing to notice is that we get error router/index.js file in express. could it be that the callback url has issue with express?

[ciaranj]

Is this still an issue for you ?
