将 cookie 传递给 QWebEngineView

Question

所以我有一个 python 代码可以将 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 none 个建议被唤醒。

但是这个例子有效 --> 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)

    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_())
