Transferring session & auth data when QWebView calls createWindow()

[admoore]

Hello, I'm new to these forums. I have posted this question to the PyQT mailing list several weeks ago, but got no response whatsoever, so I thought I'd try here.

I have a web browser application written in PyQt4 which uses a subclassed QWebView. If I load a URL that is password protected, or uses a web session (such as php session) for security, and then subsequently click a link that opens a new window (e.g. target="_blank" or javascript window.open()), the new window opens without authentication or session data and a 403 error results.

The following code illustrates this problem by opening a password-protected page on my website where you can click a link with "target=_blank" set.

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *
import sys
 
class mybrowser(QWebView):
 
    def __init__(self, parent=None):
        super(mybrowser, self).__init__(parent)
        url = QUrl ("http://www.alandmoore.com/wwwtest")
        url.setUserName("test")
        url.setPassword("test123")
        self.load(url)
 
    def createWindow(self, type):
        self.w = mybrowser()
        self.w.show()
        return self.w
 
if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = mybrowser()
    w.show()
    app.exec_()

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *
import sys

class mybrowser(QWebView):

    def __init__(self, parent=None):
        super(mybrowser, self).__init__(parent)
        url = QUrl ("http://www.alandmoore.com/wwwtest")
        url.setUserName("test")
        url.setPassword("test123")
        self.load(url)

    def createWindow(self, type):
        self.w = mybrowser()
        self.w.show()
        return self.w

if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = mybrowser()
    w.show()
    app.exec_()

To copy to clipboard, switch view to plain text mode 

How can I get new windows to retain the security credentials of the parent window?

The easiest way would probably be to share the network access manager instance between the two windows.

Thanks for your help. I tried changing the createWindow method to:

def createWindow(self, type):
        self.w = mybrowser()
        self.w.page().setNetworkAccessManager(self.page().networkAccessManager())
        self.w.show()
        return self.w

def createWindow(self, type):
        self.w = mybrowser()
        self.w.page().setNetworkAccessManager(self.page().networkAccessManager())
        self.w.show()
        return self.w

To copy to clipboard, switch view to plain text mode 

But that causes a segfault. What's the basic MO for sharing a networkAccessManager?

Ok, I think I got it figured out; this seems to work:

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *
from PyQt4.QtNetwork import *
import sys
 
class mybrowser(QWebView):
 
    def __init__(self, parent=None, nam=None):
        super(mybrowser, self).__init__(parent)
        self.nam = nam or QNetworkAccessManager()
        self.page().setNetworkAccessManager(self.nam)
        url = QUrl ("http://www.alandmoore.com/wwwtest")
        url.setUserName("test")
        url.setPassword("test123")
        self.load(url)
 
    def createWindow(self, type):
        self.w = mybrowser(None, self.nam)
        self.w.show()
        return self.w
 
if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = mybrowser()
    w.show()
    app.exec_()

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *
from PyQt4.QtNetwork import *
import sys

class mybrowser(QWebView):

    def __init__(self, parent=None, nam=None):
        super(mybrowser, self).__init__(parent)
        self.nam = nam or QNetworkAccessManager()
        self.page().setNetworkAccessManager(self.nam)
        url = QUrl ("http://www.alandmoore.com/wwwtest")
        url.setUserName("test")
        url.setPassword("test123")
        self.load(url)

    def createWindow(self, type):
        self.w = mybrowser(None, self.nam)
        self.w.show()
        return self.w

if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = mybrowser()
    w.show()
    app.exec_()

Thanks for pointing me in the right direction!!
