Phalcon and PSR-7 message interfaces.

Hi, I'm trying to create a new Oauth server using this library: https://github.com/thephpleague/oauth2-server

My problem is that they are using the PSR-7 message interface, so if I want to validate a request I have to pass a ResponseInterface and a ServerRequestInterface to the validation method.

I want to know if is it possible to get such interfaces or if I need to create a new Phalcon request/response object implementing the interfaces or do something different.

Sorry I'm a complete newbie and need help on this, I'm using Phalcon v2.1.0 RC1 with PHP 7.0.5

Thanks in advance!

Just implement new response which will implement both phalcon's ResponseInterface and psr-7 responseinterface. Also you can create something like ResponseBridge which will implement only psr-7 response interface and which will return proper values from phalcon's response accesed using di.

Hey,

I'm currently in the process of implementing something similar myself, and after creating a convertor method to try to do this and going down a long-winded path, their is a better way. Import Guzzle PSR7 into your project and you can instantiate a request object with a convenience method as shown:

    use GuzzleHttp\Psr7\ServerRequest;
     //in your controller action method
     $response = new PhalconResponsePSR7(); // I'm still working on this part
        try {

            // Try to respond to the access token request
            $serverRequest = ServerRequest::fromGlobals(); // instantiates a Guzzle serverRequest  from the global request vars
            echo $server->respondToAccessTokenRequest($serverRequest, $response);

        } catch (OAuthServerException $exception) {

        // All instances of OAuthServerException can be converted to a PSR-7 response
        $this->view->disable();

        //Create a response instance
        $presponse = new \Phalcon\Http\Response();

        //Set the content of the response
        $presponse->setContent($exception->generateHttpResponse($response)->getBody());


        //Return the response
        return $presponse;

    } catch (\Exception $exception) {

        // Catch unexpected exceptions
        $body = $response->getBody();
        $body->write($exception->getMessage());
        echo $body;

    }

This is very basic and I'm still working on the response (though that's slightly more simple I believe) but it should get you started

@TommyBs I have the same problem, please let me know when You will finish PhalconResponsePSR7

I've created such class:

class ResponseParser extends Plugin
{
    public static function parse(ResponseInterface $psr7Response, \Phalcon\Http\Response $phalconResponse)
    {
        $stream = $psr7Response->getBody();
        $stream->rewind();

        return $phalconResponse
            ->setStatusCode($psr7Response->getStatusCode())
            ->setContent($stream->getContents());
    }
}
