How get raw answer data in QWebEngineView? - qt

Question

Next examples work on small html pages, but dont work if page return big html data or json
I try this after loadFinished signal
view->page()->toHtml([cc](const QString &result){
qDebug() << "result ready";
qDebug() << "result string ="<<result;
});
I see "result ready", but second string not print, also I try this:
v->page()->runJavaScript("function jsfun(){return document.getElementsByTagName('html')[0].outerHTML;};");
//v->page()->runJavaScript("alert(jsfun())"); //work correctly
v->page()->runJavaScript("jsfun();",[this](const QVariant &v) {
qDebug() << "result ready";
qDebug() << "result string ="<<v.toString();
});
but again dont see second string

All example work correctly, but if buffer very big qDebug dont print data, you can write data to file or print part of data
Example (call toHtml after loadFinished signal) :
view->page()->toHtml([cc](const QString &result){
QFile file("outerHTML.html");
if(!file.open(QFile::WriteOnly | QFile::Text)){
qDebug() << "Cannot create a file";
return;
}
QTextStream stream(&file);
stream << buff;
file.close();
}
