Download full web page

[Black Cat]

Hi guys, it's possible to download a full web page with the QtWebEngine (Python3)?

First you have to register to downloadRequested(QWebEngineDownloadItem *download) signal emitted by the default profile.

Then in the slot method (sorry C++ code)

void downloadRequested(QWebEngineDownloadItem *download)
{
    if(download->isSavePageDownload())
        {
        download->setSavePageFormat(QWebEngineDownloadItem::CompleteHtmlSaveFormat);
        download->accept();
        }
}

This method is called on response to a right-click on "Save Page" in the context menu of the webview.

Sure, Qt WebEngine's purposes is to let you download and view webpages.

If you meant "download to disk", call the toHtml() function (see https://doc.qt.io/qtforpython/PySide6/QtWebEngineCore/QWebEnginePage.html#PySide6.QtWebEngineCore.PySide6.QtWebEngineCore.QWebEnginePage.toHtml ) this will give you the web page as a HTML document, but you'll need to download the assets (such as images) separately.

But it's possible to create the same signal of the button "Save Page"? Because this method will link directly the images with the source (without download the images)?

If you look on @JKSH's page there is https://doc.qt.io/qtforpython/PySide6/QtWebEngineCore/QWebEnginePage.html#PySide6.QtWebEngineCore.PySide6.QtWebEngineCore.QWebEnginePage.save

This is a short cut for the following actions:

Trigger the Save web action.

Accept the next download item and set the specified file path and save format.

@JonB Can I use it with PyQT5? What I'm doing wrong?

        try:
            self.wvTest.page().save(
                # Working (output of indexed image)
                filepath, format=QWebEngineDownloadItem.MimeHtmlSaveFormat
                # Not working
                # filepath, format=QWebEngineDownloadRequest.MimeHtmlSaveFormat
            )
