Passing cookies to QWebEngineView

Question

所以我有一个python代码将url转换为pdf，就像下面的

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()

我有一个cookie.txt文件，内容在

下面

[
{
"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"
}
]

是否有办法传递cookie.txt到QWebEngineView或QtWebEngineWidgets??

好吧，这些建议都没用。

但是这个例子成功了——>https://github.com/PyQt5/PyQt/blob/master/QWebEngineView/SetCookies.py

这是我的完整代码

import sys

from PyQt5.QtCore import QUrl, QTimer, QDateTime, Qt
from PyQt5.QtGui import QPageLayout, QPageSize

import argparse
import os
import json
cookie_file = None
class Window(QtWebEngineWidgets.QWebEngineView):
def __init__(self, *args, **kwargs):
super(Window, self).__init__(*args, **kwargs)
self.cookieStore = self.page().profile().cookieStore()
def initCookies(self, cookie_file):
if cookie_file:
with open("output/"+cookie_file, encoding='utf8') as f:
cookies = json.load(f)
for cookie in cookies:
qcookie = QNetworkCookie()
qcookie.setName(cookie.get('name', '').encode())
qcookie.setValue(cookie.get('value', '').encode())
qcookie.setDomain(cookie.get('domain', ''))
qcookie.setPath(cookie.get('path', ''))
qcookie.setExpirationDate(
QDateTime.fromString(str(cookie.get('expirationDate', 0)),
Qt.ISODate))
qcookie.setHttpOnly(cookie.get('httpOnly', False))
qcookie.setSecure(cookie.get('secure', False))
self.cookieStore.setCookie(qcookie, QUrl())

def main():
file_name = 'ABC123.pdf'

if not os.path.exists(directory):
os.makedirs(directory)
QTimer.singleShot(2000, lambda: loader.page().printToPdf(directory+file_name, pageLayout=layout))

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