website requires authentication

[prajith]

I am developing an application that uses the ‘QWebview’ to display the websites on the internet.

My problem is, the website which I am trying to load has a authentication popup window (HTTP BASIC AUTH) so you can enter a username and password, after the authorization, when I try to open a link in new window or tab it is keep asking me the same popup instad of loading the page directly. Here is my Webview subclass.

WebView::WebView(QWidget *parent) : QWebView(parent) {
        page()->deleteLater();
        QWebPage *newWeb = new QWebPage();
 
        NetworkAccessManager *network = new NetworkAccessManager();
        setPage(newWeb);
        setRenderHints(QPainter::SmoothPixmapTransform | QPainter::TextAntialiasing | QPainter::Antialiasing);
 
        page()->setForwardUnsupportedContent(true);
        page()->setNetworkAccessManager(network);
        this->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
        this->settings()->setAttribute(QWebSettings::JavaEnabled, true);
        this->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
        this->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);
        this->settings()->setAttribute(QWebSettings::LocalStorageDatabaseEnabled, true);
        this->settings()->setAttribute(QWebSettings::OfflineWebApplicationCacheEnabled, true);
        this->settings()->setAttribute(QWebSettings::OfflineStorageDatabaseEnabled, true);
}
 
WebView *WebView::createWindow(QWebPage::WebWindowType type)
{
        WebView *view = new WebView;
        return view;
 
}

WebView::WebView(QWidget *parent) : QWebView(parent) {
        page()->deleteLater();
        QWebPage *newWeb = new QWebPage();

        NetworkAccessManager *network = new NetworkAccessManager();
        setPage(newWeb);
        setRenderHints(QPainter::SmoothPixmapTransform | QPainter::TextAntialiasing | QPainter::Antialiasing);

        page()->setForwardUnsupportedContent(true);
        page()->setNetworkAccessManager(network);
        this->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
        this->settings()->setAttribute(QWebSettings::JavaEnabled, true);
        this->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
        this->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);
        this->settings()->setAttribute(QWebSettings::LocalStorageDatabaseEnabled, true);
        this->settings()->setAttribute(QWebSettings::OfflineWebApplicationCacheEnabled, true);
        this->settings()->setAttribute(QWebSettings::OfflineStorageDatabaseEnabled, true);
}

WebView *WebView::createWindow(QWebPage::WebWindowType type)
{
        WebView *view = new WebView;
        return view;

}

To copy to clipboard, switch view to plain text mode 

If anyone can help me on this, that would be great.

Thanks.

The cached credentials will probably be available to all views that share the same QNetworkAccessManager. You create a new instance for each view.

Can you explain a bit more? as I'm just confused about this, or if you can show me some examples, that would be great.

[ChrisW67]

Every time you create a new WebView your code creates a new NetworkAccessManager. Therefore every view, including the one your createwindow() code creates, has a distinct QNetworkAccessManager and distinct set of cached credentials and has to separately authenticate. You fix this by sharing the same NetworkAccessManager between WebViews.

Thanks for your help, I'm trying to implement new code right now.

Hope I can make it work

btw, do you have any examples?
