Mojolicious::Plugin::OAuth2 - Auth against OAUth2 APIs


   plugin 'OAuth2',
       facebook => {
          key => 'foo',
          secret => 'bar' 
   get '/auth' => sub {
      my $self=shift;
      $self->get_token('facebook',on_success=>sub {

   get '/auth' => sub {
      my $self = shift;
          sub {
              my $delay = shift;
              $self->get_token(facebook => $delay->begin)
          sub {
              my($delay, $token, $tx) = @_;
              return $self->render_text($tx->res->error) unless $token;
              return $self->render_text($token);

   my $token = $self->get_token('facebook'); # synchronous request


This Mojolicious plugin allows you to easily authenticate against a OAuth2 provider. It includes configurations for a few popular providers, but you can add your own easily as well.

Note that OAuth2 requires https, so you need to have the optional Mojolicious dependency required to support it. Call

   $ mojo version

to check if it is installed.


get_authorize_url <$provider>, <%args>

Returns a Mojo::URL object which contain the authorize URL. This is useful if you want to add the authorize URL as a link to your webpage instead of doing a redirect like get_token() does. %args is optional, but can contain:

  • authorize_query

    Either a hash-ref or an array-ref which can be used to give extra query params to the URL.

  • redirect_uri

    Useful if you want to go back to a different page than what you came from. The default is:

  • scope

    Scope to ask for credentials to. Should be a space separated list.

  • state

    A string that will be sent to the identity provider. When the user returns from the identity provider, this exact same string will be carried with the user, as a GET parameter called state in the URL that the user will return to.

get_token <$provider>, <%args>

Will redirect to the provider to allow for authorization, then fetch the token. The token gets provided as a parmeter to the callback function. Usually you want to store the token in a session or similar to use for API requests. Supported arguments:


Callback method to handle the provided token. Gets the token as it's only argument


Callback method to handle any error. Gets the failed transaction as it's only argument.


Scope to ask for credentials to. Should be a space separated list.


Use async request handling to fetch token.

    $self->get_token($provider => ..., sub {
        my($oauth2, $token, $tx) = @_;

"delay" is not an key in the %args hash, but rather a callback you can give at the end of the argument list. This callback will then force "async", and be used as both a success and error handle: $token will contain a string on success and undefined on error.



Takes a hashref of providers, each one with a hashref of options. For instance:

    plugin 'OAuth2', {
       iusethis => {
          authorize_url => 'iut.com/auth',
          token_url => 'iut.com/token',
          key => 'foo',
          secret => 'bar',

The plugin includes configurations a few providers, to use those, just set the key and secret. The currently supported providers are:


OAuth for facebook's graph API, http://graph.facebook.com/.


Authentication for Dailymotion video site.


Google.com authentication.
