How to use the passport-oauth1.prototype function in passport-oauth1

Strategy.prototype.authenticate = function(req, options) {
  // When a user denies authorization on Twitter, they are presented with a link
  // to return to the application in the following format (where xxx is the
  // value of the request token):
  //
  //     http://www.example.com/auth/twitter/callback?denied=xxx
  //
  // Following the link back to the application is interpreted as an
  // authentication failure.
  if (req.query && req.query.denied) {
    return this.fail();
  }
  
  // Call the base class for standard OAuth authentication.
  OAuthStrategy.prototype.authenticate.call(this, req, options);
