Accessing Https, host requires authentication message

[roseicollis]

@SGaist Hi, I asked about it and my workmate told me that we use cookies and that maybe its something like the Token you said. To understand better the behaviour: in every request I do to the webservice I have to send the username and password so each time it 'logs in'

May it be because the webservice returns a 204 (which is a 'Ok but I have nothing for you') and the Qt interprets it as it is not ok??

[SGaist]

Wait, then what do you mean it doesn't work ? If you get 204 it means that you succeeded but you won't receive any data.

Hi. Sorry I was not sure if was a 204. My workmate told me that maybe this was the cause but then I tried something: If I put the url where I do the request on firefox for example, it is ok and it returns the json list so I suppose that it is not a 204. But this url in my code returns what I said about Host requires authentication and I suppose that its something I'm doing wrong with my code and Qt.

[SGaist]

Can you show how you are doing these requests ?

[roseicollis]

Hi Sgaist,

Sorry for answering so late but I was outside. The request more specifically is this:

_Url= "https://myweb.com/Ob/places?INFO1=ABCDEF&password=012345&username=Mario";
QNetworkRequest request(_Url);
QNetworkReply *myReply = nam->get(request);

I don't do any other thing...

[SGaist]

It's not how you should do the request, search for "basic http authentication" and QNetworkAccessManager::authenticationRequired

[roseicollis]

@SGaist oh sorry!! I think you mean this:
I tried with:

Constructor:

nam = new QNetworkAccessManager(this);
QObject::connect ( nam, SIGNAL(authenticationRequired(QNetworkReply*,QAuthenticator*)), this, SLOT(onAuthenticationRequestSlot(QNetworkReply*,QAuthenticator*)) );

And then this, but it never gets into here...

void WPConfigs12::onAuthenticationRequestSlot(QNetworkReply *aReply, QAuthenticator *aAuthenticator)
{
     qDebug() << "INSIDE ";
    aAuthenticator->setUser("Mario");
    aAuthenticator->setPassword("012345");
}

[SGaist]

You really should get more details from your colleague on how what he uses to handle user authentication

[roseicollis]

@SGaist Is it normal that the "INSIDE" qDebug message is not pritned? I mean... its like the connect doesn't work and maybe its because i did it wrong... (last time this happened to me was because I was working with threads and I forgot to start it so the connect failed.)

[SGaist]

Your connect statement looks fine. Do you have any error message on the console ?

[roseicollis]

@SGaist No, nothing...In the compile output there is nothing wrong. I just had QLayout: Attempting to add QLayout "" to WizardPage2"WizardPage2", which already has a layout in Applicatiion output but this does not affect the program... and the connect itsself has anything it need to work because I have others that run with no problem. (Have what it needs = Q_OBJECT declared in header and so on).
That's why I asked if maybe I needed to start anything as it was a thread (If you work with threads and don't start them, you have the same problem)

[SGaist]

Unless you put your QNAM in a thread, no theres nothing special you need to do.
As a last restort, you can set the Authorization header yourself on the query

[roseicollis]

@SGaist THats so strange.... I hate when something seems to work fine but doesnt.. hehe
How do you set it with the query?

[SGaist]

Use setRawHeader from QNetworkRequest with Authorization as the name
