OAuth2 do not receive token

Brunner

Hi,

I am trying to connect to the API of BimCollab Connection API .

Using Qt's QOAuth2AuthorizationCodeFlow class.

I get the code back after the authentication request but then the token request to the server is lost.

When I send the URL I received via Postman, I get the token back.

Authentication:

Code snippet:

mReplyHandler = std::make_unique<QOAuthHttpServerReplyHandler>(QHostAddress::LocalHost, 5000); //

  qDebug() << mReplyHandler->callback() << mReplyHandler->port();
  //
  // mReplyHandler->setCallbackPath("Callback");
  //
  mOAuth2->setModifyParametersFunction([=](QAbstractOAuth::Stage stage, QVariantMap* params) {
    switch (stage)
    {
      case QAbstractOAuth::Stage::RequestingAuthorization:
        params->insert("response_type", "code");
        params->insert("redirect_uri", "http://localhost:5000/Callback");
        params->insert("scope", "openid offline_access bcf");
        params->insert("code_challenge_method", "S256");
        break;
      case QAbstractOAuth::Stage::RequestingAccessToken:
        //
        qDebug() << "PARAMS CODE" << params->value("code");
        params->insert("code", QUrl::fromPercentEncoding(params->value("code").toByteArray()));
        break;
      case QAbstractOAuth::Stage::RequestingTemporaryCredentials:
        qDebug() << params;
        break;
      case QAbstractOAuth::Stage::RefreshingAccessToken:
        break;
      default:
        break;
    }
  });

  mOAuth2->setAuthorizationUrl(mAuthentication.mOauth2AuthUrl.GetQString());
  mOAuth2->setAccessTokenUrl(mAuthentication.mOauth2TokenUrl.GetQString());
  mOAuth2->setClientIdentifierSharedKey("k!xWcjad!u@L%ZWHc%%yKtMTqR%o1be@qWfWYaDL");
  mOAuth2->setClientIdentifier("PlayGround_Client");

Console output:

solved with

case QAbstractOAuth::Stage::RequestingAccessToken:
        params->insert("code", params->value("code"));
        params->insert("redirect_uri", "http://localhost:5000/Callback");
        params->insert("scope", "openid offline_access bcf");
        params->insert("code_challenge_method", "S256");
        break;
