Print cookies from QNetworkCookie, PyQt4

Question

I am trying to save all cookies that I receive from a website and print them. Please help me make it work, because I think I don’t store anything, and that is the reason I have nothing to output.

I am testing this code on google website and I am sure that they store cookies when you get to the page.

So, I'm trying to get all the cookies available and print them. here is the code:

#! /usr/bin/env python2.7 from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtNetwork import * from PyQt4.QtWebKit import * import sys, os, simplejson, signal class MainWindow(QMainWindow): def __init__(self): QMainWindow.__init__(self) self.tabs = QTabWidget() self.setCentralWidget(self.tabs) self.settings = QSettings() self.numberOfTabs = 0 self.cookies = QNetworkCookieJar() self.cookies.setAllCookies([QNetworkCookie.parseCookies(c)[0] for c in self.get('cookiejar')]) def put(self, key, value): self.settings.setValue(key, simplejson.dumps(value)) self.settings.sync() def get(self, key): v = self.settings.value(key) return simplejson.loads(unicode(v.toString())) def addNewTab(self, url=QUrl('')): self.numberOfTabs += 1 self.tabs.setCurrentIndex(self.tabs.addTab(Tab(QUrl(url)),'%s'%str(self.numberOfTabs))) self.setCookies() return self.tabs.currentWidget() def setCookies(self): self.put('cookiejar', [str(c.toRawForm()) for c in self.cookies.allCookies()]) print self.get('cookiejar') class Tab(QWebView): def __init__(self, url): QWebView.__init__(self) self.load(url) if __name__ == '__main__': app = QApplication(sys.argv) browser = MainWindow() browser.addNewTab('https://google.com') browser.show() if signal.signal(signal.SIGINT, signal.SIG_DFL): sys.exit(app.exec_()) app.exec_()

You should loadFinished wait for loadFinished before checking the cookies, anyway, maybe something similar works for you, here I redefine QNetworkCookieJar and do all the work of storing and loading cookies:

 #!/usr/bin/env python #-*- coding:utf-8 -*- import sip sip.setapi('QString', 2) sip.setapi('QVariant', 2) from PyQt4 import QtCore, QtGui, QtWebKit, QtNetwork class cookieJar(QtNetwork.QNetworkCookieJar): def __init__(self, cookiesKey, parent=None): super(cookieJar, self).__init__(parent) self.mainWindow = parent self.cookiesKey = cookiesKey cookiesValue = self.mainWindow.settings.value(self.cookiesKey) if cookiesValue: cookiesList = QtNetwork.QNetworkCookie.parseCookies(cookiesValue) self.setAllCookies(cookiesList) def setCookiesFromUrl (self, cookieList, url): cookiesValue = self.mainWindow.settings.value(self.cookiesKey) cookiesArray = cookiesValue if cookiesValue else QtCore.QByteArray() for cookie in cookieList: cookiesArray.append(cookie.toRawForm() + "\n") self.mainWindow.settings.setValue(self.cookiesKey, cookiesArray) return super(cookieJar, self).setCookiesFromUrl(cookieList, url) class webView(QtWebKit.QWebView): def __init__(self, cookiesKey, url, parent=None): super(webView, self).__init__(parent) self.cookieJar = cookieJar(cookiesKey, parent) self.page().networkAccessManager().setCookieJar(self.cookieJar) class myWindow(QtGui.QMainWindow): def __init__(self, parent=None): super(myWindow, self).__init__(parent) self.cookiesKey = "cookies" self.centralwidget = QtGui.QWidget(self) self.tabWidget = QtGui.QTabWidget(self.centralwidget) self.tabWidget.setTabsClosable(True) self.verticalLayout = QtGui.QVBoxLayout(self.centralwidget) self.verticalLayout.addWidget(self.tabWidget) self.actionTabAdd = QtGui.QAction(self) self.actionTabAdd.setText("Add Tab") self.actionTabAdd.triggered.connect(self.on_actionTabAdd_triggered) self.lineEdit = QtGui.QLineEdit(self) self.lineEdit.setText("http://www.example.com") self.toolBar = QtGui.QToolBar(self) self.toolBar.addAction(self.actionTabAdd) self.toolBar.addWidget(self.lineEdit) self.addToolBar(QtCore.Qt.ToolBarArea(QtCore.Qt.TopToolBarArea), self.toolBar) self.setCentralWidget(self.tabWidget) self.settings = QtCore.QSettings() @QtCore.pyqtSlot() def on_actionShowCookies_triggered(self): webView = self.tabWidget.currentWidget() listCookies = webView.page().networkAccessManager().cookieJar().allCookies() for cookie in listCookies: print cookie.toRawForm() @QtCore.pyqtSlot() def on_actionTabAdd_triggered(self): url = self.lineEdit.text() self.addNewTab(url if url else 'about:blank') def addNewTab(self, url): tabName = u"Tab {0}".format(str(self.tabWidget.count())) tabWidget= webView(self.cookiesKey, url, self) tabWidget.loadFinished.connect(self.on_tabWidget_loadFinished) tabWidget.load(QtCore.QUrl(url)) tabIndex = self.tabWidget.addTab(tabWidget, tabName) self.tabWidget.setCurrentIndex(tabIndex) @QtCore.pyqtSlot() def on_tabWidget_loadFinished(self): print self.settings.value(self.cookiesKey) if __name__ == "__main__": import sys app = QtGui.QApplication(sys.argv) app.setApplicationName('myWindow') main = myWindow() main.resize(666, 333) main.show() sys.exit(app.exec_())
