将cookie传递给QWebEngineView

Question

因此，我有一个python代码，它将url转换为pdf，如下所示

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，内容如下

    [
    {
        "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"
    }
]

有没有办法将cookie.txt传递给QWebEngineView或QtWebEngineWidgets？

好的，所有的建议都没有用。

但是这个例子奏效了--> https://github.com/PyQt5/PyQt/blob/master/QWebEngineView/SetCookies.py

这是我的完整代码

import sys
from PyQt5 import QtWidgets, QtWebEngineWidgets
from PyQt5.QtCore import QUrl, QTimer, QDateTime, Qt
from PyQt5.QtGui import QPageLayout, QPageSize
from PyQt5.QtWidgets import QApplication
from PyQt5.QtNetwork import QNetworkCookie
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'
    parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
    parser.add_argument("--url", help="Type url", required=True)
    parser.add_argument("--output", help="Type output pdf file name")
    parser.add_argument("--cookie", help="Type cookie file name")
    args = parser.parse_args()
    config = vars(args)
    url = config['url']
    output = config['output']
    cookie = config['cookie']
    if output:
        file_name = output
    if cookie:
        cookie_file = cookie

    app = QtWidgets.QApplication(sys.argv)
    loader = Window()
    loader.initCookies(cookie_file)
    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):
        directory = "/htmltopdf/output/"
        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_())
