Oauth2 with code and token

Pinky

I try to get the code from an API to request a token. I can't read out the code provided by the redirect url (with my qt app).

The browser opens and I can loging but afterwards the QT does not get the code and I cannot authenticate further. The code is based on the reddit example.

Might someone has an idea?

oauth2.setAuthorizationUrl(QUrl(".../oauth/authorize"));
oauth2.setAccessTokenUrl(QUrl("..../oauth/token"));
oauth2.setScope("READSYSTEM");
oauth2.setClientIdentifier("10ba4ca31a5344868b32fe3f36576e00");
oauth2.setClientIdentifierSharedKey("qX+JBXrc2973loCZ9HeZ0JP1P7QqyM9vCRwr9sBH/hI=");

auto replyHandler = new myReplyHandler(this);
oauth2.setReplyHandler(replyHandler);

I have my own callback written for redirect url. I cannot use localhost for that specific application.

connect(&oauth2, &QOAuth2AuthorizationCodeFlow::statusChanged, [=](
           QAbstractOAuth::Status status) {
       if (status == QAbstractOAuth::Status::Granted)
           emit authenticated();
   });
   oauth2.setModifyParametersFunction([&](QAbstractOAuth::Stage stage, QVariantMap *parameters) {
       if (stage == QAbstractOAuth::Stage::RequestingAuthorization && isPermanent())
           parameters->insert("duration", "permanent");
   });
   connect(&oauth2, &QOAuth2AuthorizationCodeFlow::authorizeWithBrowser,
           &QDesktopServices::openUrl);

oauth2->grant();

Hi and welcome to devnet,

Can you explain exactly what happens after you sign in successfully ?

When I have signed (on the authentication page) in and clicked on the captcha I will be redirected to the url where I can get the code. The code is there and I see the message in the browser. But I should receive it directly in my program parse it and further use for the oauth process.
