@RicTa said in WebEngine Nanobrowser not able to pass Antibot Validation:

indeed in the meantime I have open this bug here:
https://bugreports.qt.io/browse/QTBUG-107451
please let me know in case I made some mistakes in creating it.
thanks a lot for you support

Thanks! Your bug report looks fine to me, and I see that you are having a productive discussion with an engineer who is working on Qt WebEngine.

ok looks like I've stumbled upon https://bugreports.qt.io/browse/QTBUG-86896

Hi @SGaist ,
One thing that made me skeptical about the info on the introduction page, was the affirmative that webassembly doesn't support threads, which is not an absolute true, in fact is relatively simple to enable thread support with the correct emscripten version.
But everything so far is telling me that is not possible, or at least it will be very hard to compile wasm as shared.

@Sudip-Ghimire
subclass QNetworkAccessManager and reimplement createRequest and call the base class implementation.
Then set your custom NAM to the QWebPage:
https://doc.qt.io/archives/qt-5.5/qwebpage.html#setNetworkAccessManager

no, i know that a browser send kerberos ticket with http header to server and the server check ticket and show user page without any login.
I want implement this scenario using qtwebengine. I tested this issue using free ipa package on linux and by firefox. If client is joined to domain, login to free ipa dashboard is done automatically.

@mit_cruze Unless I missed something, it's highly unlikely that building Qt 5.12.0 with the options you passed ended in installing it in /usr/local/Qt-5.7.1.

Thanks Wieland for taking a look. And thanks for the mailing list suggestion! Good to know of more Qt resources.

I've filed a bug: https://bugreports.qt.io/browse/QTBUG-56774

In my case this function works:

onFeaturePermissionRequested: { console.log("onFeaturePermissionRequested"); webEngineView.grantFeaturePermission(securityOrigin, feature, true); }

Tested on Qt 5.6 and Qt 5.7 on Desktop and Embedded

@Wieland No, we are using the <video> tag in HTML5, together with JS to play webM format video. With 5.6, the video goes up all the time till the system crashes.

The problem is disappeared in 5.7 with newer Chromium core, but it leads out a new problem as indicated the https://bugreports.qt.io/browse/QTBUG-53411.

When we use 5.7, the memory is fairly stable, but then after the first run, the JS will fail to work with the application due to a bug in QwebchannelTransport.

We tried to build QT from source code, but the WebEngine won't build (see my other post).

We are looking for a compiled WebEngine module with the bugs fixed as indicated in the QTBug-53411.

Thank you.

The solution was simple, i was inattentive, but Web Engine Team helps me, thanks guys

webView.onNavigationRequested: { if(request.navigationType === WebEngineView.BackForwardNavigation) { print("onNavigationRequested", request.url) request.action = WebEngineView.IgnoreRequest; } }

Then it's rather QNetworkAccessManager that should be of interest.
