Net::Twitter::Role::OAuth - Net::Twitter role that provides OAuth instead of Basic Authentication

version 4.01043

  use Net::Twitter;
  my $nt = Net::Twitter->new(
      traits          => ['API::RESTv1_1', 'OAuth'],
      consumer_key    => "YOUR-CONSUMER-KEY",
      consumer_secret => "YOUR-CONSUMER-SECRET",
  );
  # Do some Authentication work. See EXAMPLES
  my $tweets = $nt->friends_timeline;
  my $res    = $nt->update({ status => "I CAN HAZ OAUTH!" });

Net::Twitter::Role::OAuth is a Net::Twitter role that provides OAuth authentication instead of the default Basic Authentication.
Note that this client only works with APIs that are compatible to OAuth authentication.

Beginning with version 3.02, it is necessary for web applications to pass the "callback" parameter to "get_authorization_url". In the absence of a callback parameter, when the user authorizes the application a PIN number is displayed rather than redirecting the user back to your site.

See the "examples" directory in this distribution for working examples of both desktop and web applications.
Here's how to authorize users as a desktop app mode:
  use Net::Twitter;
  my $nt = Net::Twitter->new(
      traits          => ['API::RESTv1_1', 'OAuth'],
      consumer_key    => "YOUR-CONSUMER-KEY",
      consumer_secret => "YOUR-CONSUMER-SECRET",
  );
  # You'll save the token and secret in cookie, config file or session database
  my($access_token, $access_token_secret) = restore_tokens();
  if ($access_token && $access_token_secret) {
      $nt->access_token($access_token);
      $nt->access_token_secret($access_token_secret);
  }
  unless ( $nt->authorized ) {
      # The client is not yet authorized: Do it now
      print "Authorize this app at ", $nt->get_authorization_url, " and enter the PIN#\n";
      my $pin = <STDIN>; # wait for input
      chomp $pin;
      my($access_token, $access_token_secret, $user_id, $screen_name) = $nt->request_access_token(verifier => $pin);
      save_tokens($access_token, $access_token_secret); # if necessary
  }
  # Everything's ready
In a web application mode, you need to save the oauth_token and oauth_token_secret somewhere when you redirect the user to the OAuth authorization URL.
  sub twitter_authorize : Local {
      my($self, $c) = @_;
      my $nt = Net::Twitter->new(traits => [qw/API::RESTv1_1 OAuth/], %param);
      my $url = $nt->get_authorization_url(callback => $callbackurl);
      $c->response->cookies->{oauth} = {
          value => {
              token => $nt->request_token,
              token_secret => $nt->request_token_secret,
          },
      };
      $c->response->redirect($url);
  }
And when the user returns back, you'll reset those request token and secret to upgrade the request token to access token.
  sub twitter_auth_callback : Local {
      my($self, $c) = @_;
      my %cookie = $c->request->cookies->{oauth}->value;
      my $verifier = $c->req->params->{oauth_verifier};
      my $nt = Net::Twitter->new(traits => [qw/API::RESTv1_1 OAuth/], %param);
      $nt->request_token($cookie{token});
      $nt->request_token_secret($cookie{token_secret});
      my($access_token, $access_token_secret, $user_id, $screen_name)
          = $nt->request_access_token(verifier => $verifier);
      # Save $access_token and $access_token_secret in the database associated with $c->user
  }
Later on, you can retrieve and reset those access token and secret before calling any Twitter API methods.
  sub make_tweet : Local {
      my($self, $c) = @_;
      my($access_token, $access_token_secret) = ...;
      my $nt = Net::Twitter->new(traits => [qw/API::RESTv1_1 OAuth/], %param);
      $nt->access_token($access_token);
      $nt->access_token_secret($access_token_secret);
      # Now you can call any Net::Twitter API methods on $nt
      my $status = $c->req->param('status');
      my $res = $nt->update({ status => $status });
  }

authorized
Whether the client has the necessary credentials to be authorized.
Note that the credentials may be wrong and so the request may fail.
request_access_token(verifier => $verifier)
Request the access token, access token secret, user id and screen name for this user. You must pass the PIN# (for desktop applications) or the "oauth_verifier" value, provided as a parameter to the oauth callback (for web applications) as $verifier.
The user must have authorized this app at the url given by "get_authorization_url" first.
Returns the access_token, access_token_secret, user_id, and screen_name in a list. Also sets them internally so that after calling this method, you can immediately call API methods requiring authentication.
xauth($username, $password)
Exchanges the $username and $password for access tokens. This method has the same return value as "request_access_token": access_token, access_token_secret, user_id, and screen_name in a list. Also, like "request_access_token", it sets the access_token and access_secret, internally, so you can immediately call API methods requiring authentication.
get_authorization_url(callback => $callback_url)
Get the URL used to authorize the user. Returns a "URI" object. For web applications, pass your applications callback URL as the "callback" parameter. No arguments are required for desktop applications ("callback" defaults to "oob", out-of-band).
get_authentication_url(callback => $callback_url)
Get the URL used to authenticate the user with "Sign in with Twitter" authentication flow. Returns a "URI" object. For web applications, pass your applications callback URL as the "callback" parameter. No arguments are required for desktop applications ("callback" defaults to "oob", out-of-band).
access_token
Get or set the access token.
access_token_secret
Get or set the access token secret.
request_token
Get or set the request token.
request_token_secret
Get or set the request token secret.

oauth
Prior versions used Net::OAuth::Simple. This method provided access to the contained Net::OAuth::Simple object. Beginning with Net::Twitter 3.00, the OAuth methods were delegated to Net::OAuth::Simple. They have since made first class methods. Net::Simple::OAuth is no longer used. A warning will be displayed when accessing OAuth methods via the <oauth> method. The "oauth" method will be removed in a future release.
is_authorized
Use "authorized" instead.
oauth_authorization_url
Use "get_authorization_url" instead.
oauth_token
   $nt->oauth_token($access_token, $access_token_secret);
    
Use "access_token" and "access_token_seccret" instead:
   $nt->access_token($access_token);
   $nt->access_token_secret($access_token_secret);
    

This module was originally authored by Tatsuhiko Miyagawa as "Net::Twitter::OAuth", a subclass of the "Net::Twitter" 2.x. It was refactored into a Moose Role for use in "Net::Twitter" 3.0 and above by Marc Mims. Many thanks to Tatsuhiko for the original work on both code and documentation.
