PyQt5 QWebEngine 禁用 Access-Control-Allow-Origin

Question

我需要让我的程序在它访问的任何网站上删除 Access-Control-Allow-Origin，我该怎么做？这是我现在拥有的代码：from PyQt5 import QtCore, QtGui, QtWidgets, QtWebEngineWidgetsclass Ui_MainWindow(object):  def setupUi(self, MainWindow):    MainWindow.setObjectName("MainWindow")    self.centralwidget = QtWidgets.QWidget(MainWindow)    self.centralwidget.setObjectName("centralwidget")    self.gridLayout = QtWidgets.QGridLayout(self.centralwidget)    self.gridLayout.setObjectName("gridLayout")    self.webView = QtWebEngineWidgets.QWebEngineView(self.centralwidget)    self.webView.setUrl(QtCore.QUrl("thewebsite"))    self.webView.loadFinished.connect(self.reform)    self.webView.setObjectName("webView")    self.gridLayout.addWidget(self.webView, 0, 0, 1, 1)    MainWindow.setCentralWidget(self.centralwidget)    self.statusbar = QtWidgets.QStatusBar(MainWindow)    self.statusbar.setObjectName("statusbar")    MainWindow.setStatusBar(self.statusbar)    self.retranslateUi(MainWindow)    QtCore.QMetaObject.connectSlotsByName(MainWindow)  def reform(self, ok):    payload = open('payload.js', 'r').read()    if ok:        self.webView.page().runJavaScript('alert("Ready");')        self.webView.page().runJavaScript(payload)  def retranslateUi(self, MainWindow):    _translate = QtCore.QCoreApplication.translate    MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))from PyQt5 import QtWebEngineWidgetsif __name__ == "__main__":  import sys  app = QtWidgets.QApplication(sys.argv)  MainWindow = QtWidgets.QMainWindow()  ui = Ui_MainWindow()  ui.setupUi(MainWindow)  MainWindow.setFixedSize(500, 500)  MainWindow.show()  sys.exit(app.exec_())如何使它禁用 Access-Control-Allow-Origin？
