a sample of how to use oauth with VML's passport product

passport-oauth.js

var OAuth   = require('oauth').OAuth;
var baseURL = 'https://passport.vml.com';

consumer = new OAuth(
  baseURL + '/oauth/request_token',
  baseURL + '/oauth/access_token',
  process.env.PASSPORT_OAUTH_KEY,
  process.env.PASSPORT_OAUTH_SECRET,
  '1.0', null, 'HMAC-SHA1'
);

consumer.getOAuthRequestToken(function(err, requestToken, requestTokenSecret){
  console.log('Request Token:         ', requestToken);
  console.log('Request Token Secret:  ', requestTokenSecret);

  consumer.getOAuthAccessToken(requestToken, requestTokenSecret, function(err, accessToken, accessTokenSecret){
    console.log('Access Token:          ', accessToken);
    console.log('Access Token Secret:   ', accessTokenSecret);

    consumer.get(
      baseURL + '/api/user/jlongstreet/ui.json',
      accessToken,
      accessTokenSecret,
      function(err, data, res){
        console.log(data);
      }
    );
  });
});
