Passing cookies to QWebEngineView using python

[godomainz]

so I have a python code which converts url to pdf like below

import sys
from PyQt5 import QtWidgets, QtWebEngineWidgets
from PyQt5.QtCore import QUrl, QTimer
from PyQt5.QtGui import QPageLayout, QPageSize
from PyQt5.QtWidgets import QApplication
import argparse



def _fullScreenRequested(request):
    request.accept()
    loader.showFullScreen()

def main():
    url = ''
    parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
    parser.add_argument("--url", help="Type url")
    args = parser.parse_args()
    config = vars(args)
    url = config['url']


    app = QtWidgets.QApplication(sys.argv)
    loader = QtWebEngineWidgets.QWebEngineView()
    loader.setZoomFactor(1)
    layout = QPageLayout()
    layout.setPageSize(QPageSize(QPageSize.A4Extra))
    layout.setOrientation(QPageLayout.Portrait)
    loader.load(QUrl(url))
    loader.page().pdfPrintingFinished.connect(lambda *args: QApplication.exit())

    def emit_pdf(finished):
        # loader.page().printToPdf("test.pdf", pageLayout=layout)
        QTimer.singleShot(2000, lambda: loader.page().printToPdf("test.pdf", pageLayout=layout))

    loader.loadFinished.connect(emit_pdf)
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

I have a cookie.txt with the content below

  [
    {
        "domain": "www.udemy.com",
        "expirationDate": 1714906174.734258,
        "hostOnly": true,
        "httpOnly": false,
        "name": "snexid",
        "path": "/",
        "sameSite": null,
        "secure": false,
        "session": false,
        "storeId": null,
        "value": "c6sdf99-1sdab-4sd1-86ff-2dc8sfs24511"
    }
]

is there a way to pass my cookie.txt to QWebEngineView or QtWebEngineWidgets ??

add cookie for url

[godomainz]

@892768447 any sample code on how to do that ?

[892768447]

#88

cookieStore.setCookie(cookies.front(), url)

[godomainz]

@892768447 as per your suggestion I changed the code like below

import sys
from PyQt5 import QtWidgets, QtWebEngineWidgets
from PyQt5.QtNetwork import QNetworkAccessManager, QNetworkCookie
from PyQt5.QtCore import QUrl, QTimer
from PyQt5.QtGui import QPageLayout, QPageSize
from PyQt5.QtWidgets import QApplication
import argparse

def main():
    url = ''
    parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
    parser.add_argument("--url", help="Type url")
    args = parser.parse_args()
    config = vars(args)
    url = config['url']


    app = QtWidgets.QApplication(sys.argv)
    loader = QtWebEngineWidgets.QWebEngineView()
    networkManager = QNetworkAccessManager()
    cookieJar = networkManager.cookieJar()
    cookies = cookieJar.cookiesForUrl(QUrl(url))
    web_profile = loader.page().profile()
    cookieStore = web_profile.cookieStore()
    cookieStore.setCookie(cookies.front(), QUrl(url))
    loader.setUrl(QUrl(url))
    loader.setZoomFactor(1)
    layout = QPageLayout()
    layout.setPageSize(QPageSize(QPageSize.A4Extra))
    layout.setOrientation(QPageLayout.Portrait)
    loader.load(QUrl(url))
    loader.page().pdfPrintingFinished.connect(lambda *args: QApplication.exit())

    def emit_pdf(finished):
        QTimer.singleShot(2000, lambda: loader.page().printToPdf("test.pdf", pageLayout=layout))


    loader.loadFinished.connect(emit_pdf)
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

I'm getting below error

Traceback (most recent call last):
  File ".\htmlToPdfnew.py", line 41, in <module>
    main()
  File ".\htmlToPdfnew.py", line 21, in main
    cookie.path("cookie.txt")

btw how can we specify the file path for "cookie.txt" ?

File ".\htmlToPdfnew.py", line 25, in main

change to  cookies[0]

webEngineProfile = QWebEngineProfile.defaultProfile()
cookieStore = webEngineProfile.cookieStore()

#https://doc.qt.io/qt-5/qwebenginecookiestore.html#setCookie
#cookieStore.setCookie(const QNetworkCookie &cookie, const QUrl &origin = QUrl())

cook = QNetworkCookie()
cook.setDomain('ww.udemy.com')
#cook.setExpirationDate(QDateTime) # date
cook.setPath('/')
cook.setValue('c6sdf99-1sdab-4sd1-86ff-2dc8sfs24511'.encode())
cookieStore.setCookie(cook , QUrl(url))

you can search QNetworkCookie from github like
