SYNOPSIS

use Mojolicious::Lite;

plugin 'OAuth2::Server' => {
    ... # see SYNOPSIS in Net::OAuth2::AuthorizationServer::Manual
};

group {
  # /api - must be authorized
  under '/api' => sub {
    my ( $c ) = @_;

    return 1 if $c->oauth; # must be authorized via oauth

    $c->render( status => 401, text => 'Unauthorized' );
    return undef;
  };

  any '/annoy_friends' => sub { shift->render( text => "Annoyed Friends" ); };
  any '/post_image'    => sub { shift->render( text => "Posted Image" ); };
};

any '/track_location' => sub {
  my ( $c ) = @_;

  my $oauth_details = $c->oauth( 'track_location' )
      || return $c->render( status => 401, text => 'You cannot track location' );

  $c->render( text => "Target acquired: @{[$oauth_details->{user_id}]}" );
};

app->start;

Or full fat app:

use Mojo::Base 'Mojolicious';

...

sub startup {
  my $self = shift;

  ...

  $self->plugin( 'OAuth2::Server' => $oauth2_auth_code_grant_config );
}

Then in your controller:

 sub my_route_name {
   my ( $c ) = @_;

   if ( my $oauth_details = $c->oauth( qw/required scopes/ ) ) {
     ... # do something, user_id, client_id, etc, available in $oauth_details
   } else {
     return $c->render( status => 401, text => 'Unauthorized' );
   }

   ...
 }

DESCRIPTION

This plugin implements the various OAuth2 grant types flow as described at http://tools.ietf.org/html/rfc6749. It is a complete implementation of RFC6749, with the exception of the "Extension Grants" as the description of that grant type is rather hand-wavy.

The bulk of the functionality is implemented in the Net::OAuth2::AuthorizationServer distribution, you should see that for more comprehensive documentation and examples of usage.

The examples here use the "Authorization Code Grant" flow as that is considered the most secure and most complete form of OAuth2.

METHODS

register

Registers the plugin with your app - note that you must pass callbacks for certain functions that the plugin expects to call if you are not using the plugin in its simplest form.

$self->register($app, \%config);

Registering the plugin will call the Net::OAuth2::AuthorizationServer and create a auth_code_grant that can be accessed using the defined authorize_route and access_token_route. The arguments passed to the plugin are passed straight through to the auth_code_grant method in the Net::OAuth2::AuthorizationServer module.

oauth

Checks if there is a valid Authorization: Bearer header with a valid access token and if the access token has the requisite scopes. The scopes are optional:

unless ( my $oauth_details = $c->oauth( @scopes ) ) {
  return $c->render( status => 401, text => 'Unauthorized' );
}

This calls the Net::OAuth2::AuthorizationServer::AuthorizationCodeGrant module (verify_token_and_scope method) to validate the access/refresh token.

oauth2_auth_request

This is a helper to allow you get get the redirect URI instead of directing a user to the authorize_route - it requires the details of the client:

my $redirect_uri = $c->oauth2_auth_request({
  client_id     => $client_id,
  redirect_uri  => 'https://foo',
  response_type => 'token',
  scope         => 'list,of,scopes',
  state         => 'foo=bar&baz=boz',
});

if ( $redirect_uri ) {
 # do something with $redirect_uri
} else {
  # something didn't work, e.g. bad client, scopes, etc
}

You can use this helper instead of directing a user to the authorize_route if you need to do something more involved with the redirect_uri rather than having the plugin direct to the user to the resulting redirect uri
