Error trying to get JWT

[jonmunm]

Hi Everyone

I'm trying to change the token type to JWT, and I've been following the instructions given here (https://github.com/Filsh/yii2-oauth2-server), so I created the files (In fact, I just copy them):

1. app\storage\PublicKeyStorage
2. app\storage\JwtAccessToken

Then in my config file I have something like this:

    'modules' => [
        'oauth2' => [
            'class' => 'filsh\yii2\oauth2server\Module',            
            'tokenParamName' => 'accessToken',
            'tokenAccessLifetime' => 3600,
            'useJwtAccessTokens' => true,
            'storageMap' => [
                'user_credentials' => 'app\models\User',
                'public_key' => 'app\storage\PublicKeyStorage',
                'access_token' => 'app\storage\JwtAccessToken'
            ],
            'grantTypes' => [
                'user_credentials' => [
                    'class' => 'OAuth2\GrantType\UserCredentials',
                ],
                'client_credentials' => [
                    'class' => 'OAuth2\GrantType\ClientCredentials',
                ],
                'refresh_token' => [
                    'class' => 'OAuth2\GrantType\RefreshToken',
                    'always_issue_new_refresh_token' => true
                ]
            ]
        ],

But when I send a request, I got this error:

Unknown Property – yii\base\UnknownPropertyException
Setting unknown property: filsh\yii2\oauth2server\Module::useJwtAccessTokens

So, after some research I decide to remove de 'useJwtAccessTokens' => true from the config. Then I put it in vendor\filsh\yii2-oauth2-server\Module.php. The code with the new line is like this (just a fragment of it):

    public function getServer()
    {
        if(!$this->has('server')) {
            $storages = [];
            foreach(array_keys($this->storageMap) as $name) {
                $storages[$name] = \Yii::$container->get($name);
            }

            $grantTypes = [];
            foreach($this->grantTypes as $name => $options) {
                if(!isset($storages[$name]) || empty($options['class'])) {
                    throw new \yii\base\InvalidConfigException('Invalid grant types configuration.');
                }

                $class = $options['class'];
                unset($options['class']);

                $reflection = new \ReflectionClass($class);
                $config = array_merge([0 => $storages[$name]], [$options]);

                $instance = $reflection->newInstanceArgs($config);
                $grantTypes[$name] = $instance;
            }

            $server = \Yii::$container->get(Server::className(), [
                $this,
                $storages,
                [
                    'token_param_name' => $this->tokenParamName,
                    'access_lifetime' => $this->tokenAccessLifetime,
                    'use_jwt_access_tokens' => true,
                ],
                $grantTypes
            ]);

            $this->set('server', $server);
        }
        return $this->get('server');
    }

Note where I put the option 'use_jwt_access_tokens' => true. After this, I got stuck with a new final error that says:

    "#14 {main}"
  ]
}

The only guess I can make is tha something happen with the indicated interface.

I Hope you can help me, or tell me how to proper set the config to use JWT.

Bye
