Permission request page about oauth2-bundle HOT 6 OPEN

Just as note for others trying the code above,
if ($request->getMethod() !== 'POST' || null === $event->getUser()) {
should be
if ($request->getMethod() !== 'POST' && null === $event->getUser()) {
Otherwise you will directly get a denied for your request.
Another change that is needed is that the default provided routes (Might only apply if you use symfony flex?) doesn't allow POST go /authorize, so instead of including the default route file, you will need to define the routes yourself.

With those changes it works perfectly, thanks!

To anyone having the same problem as @metasearch7, this is what I did:

Create AuthRequestResolve:

<?php

namespace App\EventListener;

use Trikoder\Bundle\OAuth2Bundle\Event\AuthorizationRequestResolveEvent;

final class AuthRequestResolve
{

    public function onAuthRequestResolve(AuthorizationRequestResolveEvent $event): void
    {
        // TODO: if using 3rd party clients, make sure the user approves access
        $event->resolveAuthorization(TRUE);
    }
}

Add this in services.yaml:

App\EventListener\AuthRequestResolve:
  tags:
    - { name: kernel.event_listener, event: trikoder.oauth2.authorization_request_resolve, method: onAuthRequestResolve }

I think maybe in the onAuthRequestResolve is where you ask the user to review the app's permissions.

Check out #177 for documentation on this. If you would like to have an intermediate page, I've done this in the event handler (though I'm not sure what the best practices are for this):

    public function onAuthorizationRequest(AuthorizationRequestResolveEvent $event): void
    {
        $request = $this->requestStack->getCurrentRequest();

        // only handle post requests for logged-in users:
        // get requests will be intercepted and shown the login form
        // other verbs we will handle as an authorization denied
        // and this implementation ensures a user is set at this point already
        if ($request->getMethod() !== 'POST' || null === $event->getUser()) {
            $event->resolveAuthorization(AuthorizationRequestResolveEvent::AUTHORIZATION_DENIED);
            return;
        }

        if (!$request->request->has('action')) {
            // 1. successful login, goes to grant page
            $content = $this->twig->render('security/grant.html.twig', [
                'scopes' => $event->getScopes(),
                'client' => $event->getClient(),
                'grant' => static::AUTHORIZATION_GRANT,
                // very simple way to ensure user gets to this point in the
                // flow when granting or denying is to pre-add their credentials
                'email' => $request->request->get('email'),
                'password' => $request->request->get('password'),
            ]);

            $response = new Response(200, [], $content);
            $event->setResponse($response);
        } else {
            // 2. grant operation, either grants or denies
            if ($request->request->get('action') == static::AUTHORIZATION_GRANT) {
                $event->resolveAuthorization(AuthorizationRequestResolveEvent::AUTHORIZATION_APPROVED);
            } else {
                $event->resolveAuthorization(AuthorizationRequestResolveEvent::AUTHORIZATION_DENIED);
            }
        }
    }

security/grant.html.twig:

<form method="post">
    {% if app.user %}
        <div class="mb-3">
            You are logged in as {{ app.user.username }}, <a href="{{ path('api_logout') }}">Logout</a>
        </div>
    {% endif %}

    <h1 class="h3 mb-3 font-weight-normal">Grant Permissions</h1>
    <input type="hidden" name="_csrf_token"
           value="{{ csrf_token('authenticate') }}"
    >
    <input type="hidden" name="email"
           value="{{ email }}"
    >
    <input type="hidden" name="password"
           value="{{ password }}"
    >

    <p>Grant the following permissions:</p>
    <ul>
        {% for scope in scopes %}
            <li>{{ scope }}: {{ scope }}</li>
        {% endfor %}
    </ul>

    <button class="btn btn-lg btn-primary" type="submit" name="action" value="{{ grant }}">
        Grant
    </button>

    <button class="btn btn-lg btn-primary" type="submit" name="action" value="Deny">
        Deny
    </button>
</form>

Any improvements to this approach would be appreciated.

I've also been looking into how this part of the Oauth2 spec can be supported by this bundle.

I don't know how the AuthorizationRequestResolveEvent can be used to achieve this as it's will involve a redirect. There's not a whole lot going on in the controller so we could just implement our own to achieve this and define the route authorize route in our app bundle.

Im still a newbie with oauth2 and I was wondering about this permission page. When I send a GET request to /authorize I'm instantly redirected to the redirect_uri registered for the client.
But does this mean the user is by default giving permission even without the permission page ? I was supposed to get an access_token but i've got nothing.
Or does it means authorization_code flow doesnt work at all ?

Is this problem resolved?

after entering the login and password, the authorization request is not displayed, but a redirect is immediately performed

/?&error=access_denied&error_description=The+resource+owner+or+authorization+server+denied+the+request.&hint=The+user+denied+the+request&message=The+resource+owner+or+authorization+server+denied+the+request.

How to make an authorization request?
