@Pablo-J-Rogina yes, and it doesn't say much more than what can be gleaned from the function signature. What is missing is any discussion of why one might want to call it (in normal circumstances that is, not to work around what apparently is a bug). Also, as I asked, whether calling it might have any adverse effects.

@ambershark Thank you very much for your help, now it's working, it seems like I was passing the IP argument incorrectly, now I know that I have to send this parameter inside a QT function. thanks!

@juanki sí, de hecho al final encontre que mi error era porque la IP la tenia que mandar dentro de un método de la librería, igual gracias por tu post :)

QHttp cosi' come il tuo modulo non puo' gestire l'http moderno, in particolare SSL. Mentre mi devo congratulare per lo sforzo profuso, suggerirei un passo indietro, perche' non puoi usare QNetworkAccessManager (o un wrapper attorno a esso)? Se la risposta alla precedente domanda e' "perche' alcune cose che mi servono non sono implementate" (di solito questo e' un problema quando si sostituisce QFtp, non QHttp), potresti considerare un wrapper attorno a libcurl? magari fruttando curlpp?

Thanks everyone for insight . I have some idea now from where i should start .

@SGaist thx - have thought the same. would work well if Active and bad coverage or coming back from suspended when multi signals are received

Don't get this the wrong way, but are you coming from Java? I'm asking because this: QHostAddress().AnyIPv4 Doesn't make any sense in C++. What you probably want is to use the scope operator - :: to access one of the enum values. As for the error, please provide the full implementation of your TCP server and mention if you use threading, if so how. Also as mentioned by @koahnig new QTcpSocket(new QObject()); This leaks 2 objects one socket and one generic QObject. You need to provide a valid pointer from the object tree to make use of the automatic deletion Qt supplies for child objects.

I have now found this thread posted 2 years ago which seems very similar to what I was looking for. The solution was to create a new QML component which create a new QML engine instance and isolates the untrusted QML code inside it. That does isolate the execution context, it does't however monitor the network traffic generated by the component. In my case network communication must be restricted to a certain set of domains, so I need to intercept network going in and out of the component, any idea how?

It's a bug in Qt. Appears everytime. Even if disable IPv6 stack.

@d1.psy so you want the cookies from the requests you already made with QtWebEngine? If so take a look at QWebEngineCookieStore (see it's signals) and "sync" the cookies into your QNAM.

@Mkowalik-Mimesis and why does it crash? What is the value of incoming QNetworkReply* ? Are you doing any fancy deletes? in your CustomNetworkManagerFactory::create() you get a QObject* passed as a parent for the QNAM to create. But you set the parent to the this pointer instead. it would be cleaner not to couple the created QNAM with your factory class by connecting signals and slots of them. Instead you should subclass QNAM, move the onIgnoreSSLErrors() slot to it and connect it to itself instead. you are overwriting your local m_networkManager member variable everytime create() is called. Which doesn't go along with a factory implementation ;) I don't know if this already solves your crash, it may be.

@M4RZB4Ni said: Hi When you dont have uSocket = new QUdpSocket(this) ; then uSocket->writeDatagram(xx will crash. as uSocket just point to random location. (dangling pointer) Next: QByteArray *priPackNuser; <<< also just a pointer. You should do ( as @SGaist mention) QByteArray priPackNuser; ( no *, means its real bytearray, not a pointer to one) So you change it from heap allocation to stack allocation. If you dont change to non pointer then you need QByteArray *priPackNuser = new QByteArray ; as else its a dangling pointer too! But no need for pointer to QByteArray here.

The server is not returning anything useful in the HTTP headers (I wouldn't expect it to): ~/tmp$ wget -S 'http://u801.wapkafile.com//g03/video/1253022/7940/c8f9a32ef15648bfa6f693102de27835/DARNA-ZAROORI-HAI-3(Movies7.In).avi?md5=TU7ibYa85byjzJyJcH_LXQ&expires=1458916610' --2016-07-27 18:21:15-- http://u801.wapkafile.com//g03/video/1253022/7940/c8f9a32ef15648bfa6f693102de27835/DARNA-ZAROORI-HAI-3(Movies7.In).avi?md5=TU7ibYa85byjzJyJcH_LXQ&expires=1458916610 Resolving u801.wapkafile.com (u801.wapkafile.com)... 8.37.229.38 Connecting to u801.wapkafile.com (u801.wapkafile.com)|8.37.229.38|:80... connected.

I expect you'll want to use a library to parse it out. I'm not sure if Qt has such functionality built-in. Perhaps have a look through the Qt Multimedia docs. Cheers.

@marlenet15 Hi, Here you can find a threaded TCP server example. You can ignore the module specific classes QDaemonApplication (think of it as QCoreApplication) and QDaemonLog you can substitute with QDebug. Enjoy! Kind regards.

QNetworkRequest req(url); reply=qnam.get(req); QObject::connect(reply,SIGNAL(finished()),this,SLOT(slotFinished()));

@mrjj I could never figure out what was calling progressDialog. So after progress dialog was created, I did timer = new QTimer(this); timer->setSingleShot(true); timer->start(5000); connect(timer, SIGNAL(timeout()), this, SLOT(testing())); and void FtpWindow::testing() { progressDialog->hide(); } crude but it works. If there were a QDialog signal for isActiveWindow or hasAppeared, it would be better. But this works. Edit: ended up using progressDialog->setAttreibute(Qt::WidgetAttribute::WA_DontShowOnScreen, true);

@djee In My Way connectToHost To Http Server Not Working, So I Call QSslConfiguration::defaultConfiguration(); Instead.

It could be. Although it was working fine in previous release with Qt 5.5.1.
