How to obtain a Token in an Autonomous Client (Username-Password Flow)

Question

I am trying to use the grant_type=password oauth flow with Twitter API. How can I implement this flow in nodejs.

var twitterConsumerKey = '';
var twitterConsumerSecret = '';

var OAuth2 = require('oauth').OAuth2;
var oauth2 = new OAuth2(
    twitterConsumerKey,
    twitterConsumerSecret,
    'https://api.twitter.com/',
    null,
    'oauth2/token',
    null
);
oauth2.getOAuthAccessToken(
    '',
    {'grant_type':'client_credentials'},
    function (e, access_token, refresh_token, results){
        console.log('bearer: ',access_token);
    }
);

@user503413 I have updated the question where Im using node-auth module. Is {'grant_type':'password'} possible in the same module? — user3180402, Feb 14 '14 at 11:50

Looks like twitter support Application Only Authentication.

I'm not familiar with the oauth module but you can use mikeal/request as follows:

var request = require('request');

request.post({
  url: 'https://api.twitter.com/',
  auth: {
    user: twitterConsumerKey,
    pass: twitterConsumerSecret
  },
  form: { grant_type:'client_credentials'},
  json: true
}, function (err, resp, body) {

  var token = body.access_token;

  //now you can use it for other APIs
  request.get({
    url: '....',
    headers: {
      Authorization: 'Bearer ' + token
    }
  }, function () {});

});

your example shows { grant_type:'client_credentials'}. Im looking for { grant_type:'password'}.I want to implement oauth client – user3180402 Feb 14 '14 at 12:31
Sorry, I misread the question. Then you are looking for the oauth __resource owner__ flow, and I think twitter doesn't support it. – José F. Romaniello Feb 14 '14 at 12:45
Yes I need resource owner flow using npm. – user3180402 Feb 14 '14 at 13:05
