$params of type string is incompatible with the type array expected by parameter $params of tinymeng\OAuth2\Connector\Gateway::post().

It seems like $token can also be of type true; however, parameter $token of tinymeng\OAuth2\Gateways\Line::parseToken() does only seem to accept string, maybe add an additional type check?
