Google OAuth with QtNetworkAuth read Reply

[Navira]

Hi, everyone. I trying to add OAuth to my desktop app. Found this example http://blog.qt.io/blog/2017/01/25/connecting-qt-application-google-services-using-oauth-2-0/
The browser opens, I confirm the form, then browser says me: Callback received. Feel free to close this page.
But I can not read a reply.
Code

class googleOAuth: public QObject
{
    Q_OBJECT
public slots:
    void googleReply(QNetworkReply *reply)
    {
        qDebug() << "Success";// <<QString::fromUtf8(reply->readAll());
        reply->deleteLater();
    }
};


auto google = new QOAuth2AuthorizationCodeFlow;
google->setScope("email");
connect(google, &QOAuth2AuthorizationCodeFlow::authorizeWithBrowser,
       &QDesktopServices::openUrl);
QJsonDocument document = QJsonDocument::fromJson(paramjson.toUtf8());
const auto object = document.object();
const auto settingsObject = object["web"].toObject();
const QUrl authUri(settingsObject["auth_uri"].toString());
const auto clientId = settingsObject["client_id"].toString();
const QUrl tokenUri(settingsObject["token_uri"].toString());
const auto clientSecret(settingsObject["client_secret"].toString());
const auto redirectUris = settingsObject["redirect_uris"].toArray();
const QUrl redirectUri(redirectUris[0].toString()); // Get the first URI
const auto port = static_cast<quint16>(redirectUri.port()); // Get the port


google->setAuthorizationUrl(authUri);
google->setClientIdentifier(clientId);
google->setAccessTokenUrl(tokenUri);
google->setClientIdentifierSharedKey(clientSecret);

auto replyHandler = new QOAuthHttpServerReplyHandler(port, this);
googleOAuth authreply;
connect(replyHandler, SIGNAL(QNetworkReply::finished), &authreply, SLOT(googleReply(QNetworkReply*)));

google->setReplyHandler(replyHandler);

google->grant();
auto reply = google->get(QUrl("https://www.googleapis.com/plus/v1/people/me"));

Output

QML debugging is enabled. Only use this in a safe environment.
QObject::connect: Parentheses expected, signal QOAuthHttpServerReplyHandler::QNetworkReply::finished in ..\DesktopApp\widget.cpp:36
QOAuth2AuthorizationCodeFlow::buildAuthenticateUrl: https://accounts.google.com/o/oauth2/auth?client_id=432................
QOAuthOobReplyHandler::networkReplyFinished: Protocol "https" is unknown
QOAuth2AuthorizationCodeFlow: Unexpected call

Can somebody help me?

[VRonin]

connect(replyHandler, SIGNAL(QNetworkReply::finished), &authreply, SLOT(googleReply(QNetworkReply*)));

this is invalid connect. it should be:
connect(replyHandler, &QNetworkReply::finished, authreply,[authreply,replyHandler]()->void{authreply->googleReply(replyHandler);});

See https://wiki.qt.io/New_Signal_Slot_Syntax

I could not get a signal.
I'm trying the other one
QOAuth2AuthorizationCodeFlow :: grant
It does not work. Every time I see
Callback received. Feel free to close this page.
In the URL received code but I can not read it.
Log

QOAuthOobReplyHandler::networkReplyFinished: Protocol "https" is unknown
QOAuth2AuthorizationCodeFlow: Unexpected call

I compile QT with key -no-openssl Maybe this is the reason?
Every time I update the page (with "Callback received. Feel free to close this page.") , I see QOAuthOobReplyHandler::networkReplyFinished: Protocol "https" is unknown

code

class googleOAuth: public QObject
{
    Q_OBJECT
public:
    //googleOAuth(QObject *parent = 0);


public slots:
    void googleReply(void)
    {
        qDebug() << "Success";// <<QString::fromUtf8(reply->readAll());
        //reply->deleteLater();
    }
};

googleOAuth authreply;
connect(google, &QOAuth2AuthorizationCodeFlow::granted,&authreply,&googleOAuth::googleReply);

If I do not connect signal

auto google = new QOAuth2AuthorizationCodeFlow;
google->setScope("email");
connect(google, &QOAuth2AuthorizationCodeFlow::authorizeWithBrowser,
       &QDesktopServices::openUrl);
QJsonDocument document = QJsonDocument::fromJson(paramjson.toUtf8());
const auto object = document.object();
const auto settingsObject = object["web"].toObject();
const QUrl authUri(settingsObject["auth_uri"].toString());
const auto clientId = settingsObject["client_id"].toString();
const QUrl tokenUri(settingsObject["token_uri"].toString());
const auto clientSecret(settingsObject["client_secret"].toString());
const auto redirectUris = settingsObject["redirect_uris"].toArray();
const QUrl redirectUri(redirectUris[0].toString()); // Get the first URI
const auto port = static_cast<quint16>(redirectUri.port()); // Get the port


google->setAuthorizationUrl(authUri);
google->setClientIdentifier(clientId);
google->setAccessTokenUrl(tokenUri);
google->setClientIdentifierSharedKey(clientSecret);

auto replyHandler = new QOAuthHttpServerReplyHandler(port, this);
google->setReplyHandler(replyHandler);
googleOAuth authreply;
//connect(google, &QOAuth2AuthorizationCodeFlow::granted,&authreply,&googleOAuth::googleReply);
google->grant();

i have this output

Hello,
I have a similar problem, when I first use the web browser (firefox, config: do not remember history):

QOAuthOobReplyHandler :: networkReplyFinished: Error transferring https://accounts.google.com/o/oauth2/token - server replied: Bad Request
QOAuth2AuthorizationCodeFlow: Unexpected call

But if I repeat google-> grant (); Is solved.

I would like to know how to catch this error: server replied: Bad Request and Unexpected call

I already tried with:
Connect to:
&QAbstractOAuth2 :: error,
&QAbstractOAuth :: requestFailed,
But not cath the error

@numaelisis I at your point now. have you got resolution? It seems like QOAuthHttpServerReplyHandler does not have code to handle this situation.
