Hello,

To begin i want to congratulate you for your work. Your lib is really useful and good. I encounter a little problem i can not solve by myself. I install your lib with composer require league/oauth2-server in a docker and implement our engine based on symfony. I use your example code like that :

use Laminas\Diactoros\ServerRequestFactory; use Laminas\Diactoros\ResponseFactory;

class tokenController extends Controller { public function init() {

Initialisation

}

public function access_token(/*ServerRequestInterface $request, ResponseInterface $response*/) {
  /* @var \League\OAuth2\Server\AuthorizationServer $server */
  $server = Registre::get('server');

  $request = ServerRequestFactory::fromGlobals();
  $response = ResponseFactory::createResponse();

  try {

    # Try to respond to the request
    return $server->respondToAccessTokenRequest($request, $response);
  } catch (\League\OAuth2\Server\Exception\OAuthServerException $exception) {

    # All instances of OAuthServerException can be formatted into a HTTP response
    return $exception->generateHttpResponse($response);

  } catch (\Exception $exception) {
    # Unknown exception
    $body = new Stream('php://temp', 'r+');
    $body->write($exception->getMessage());
    return $response->withStatus(500)->withBody($body);
  }
}

and use this curl request in terminal : curl -X "POST" "http://localhost:8095/access_token" -H "Content-Type: application/x-www-form-urlencoded" -H "Accept: 1.0" --data-urlencode "grant_type=password" --data-urlencode "client_id=myawesomeapp" --data-urlencode "client_secret=abc123" --data-urlencode "username=alex" --data-urlencode "password=whisky" --data-urlencode "scope=basic email"

I receive an empty answer and when i use a client side php i have that : "HTTP/1.1 200 OK Date: Wed, 24 Feb 2021 00:28:50 GMT Server: Apache/2.4.38 (Debian) Content-Length: 0 Content-Type: text/html; charset=UTF-8"

But when i use exit($server->respondToAccessTokenRequest($request, $response)->getBody()->__toString()); instead of return $server->respondToAccessTokenRequest($request, $response);

I obtain my json answer : {"token_type":"Bearer","expires_in":3600,"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJhdWQiOiJteWF3ZXNvbWVhcHAiLCJqdGkiOiI2MGMwMWNkZmJmYTBmMTY3ZGJlYjVmYjQwZDBjZmZiZWFkNWNhZTZiY2FlNmU3YzBmNTM1NDQ0YjAyNzE0NjFkODMyNTllMTkxMTUyMDVlOSIsImlhdCI6MTYxNDEyNzAyMiwibmJmIjoxNjE0MTI3MDIyLCJleHAiOjE2MTQxMzA2MjIsInN1YiI6IiIsInNjb3BlcyI6WyJiYXNpYyIsImVtYWlsIl19.WYZfsF4CYbDzZZwaf7_LNpg49K2Dc8bDMEmOUz9Hb-fkgNdk93QMEjlv0tfL2L2Rd3gl5OIuDIxNFhBWJJt_QczNnlj8kiWdLGAlbI84-SEubiXCtnu-xPdAYni6K22Y_E-NhSTqOmCU_mEo2bgtuUcC3hfjO9OIuyGpLw87sae24B2yCZiTO8xtLy1hXuR8B1ICsz4MJtvb3nOXmjB02drlsUx184tz7NV0jFDcWfk9YgKwl07sa3G6-AqSG6AjOErSroH71KV1hjUvRrdyYOn1m21Y6pYuiMCiKtcFL-GiteqGkwEi0SGFQam5YDa9ebLkR64a60IAlzjzxOIyLQ"}
