python - PyQt5 QWebEngine 禁用 Access-Control-Allow-Origin

Question

我需要让我的程序在其访问的任何网站上删除 Access-Control-Allow-Origin，我该如何执行此操作？这是我现在的代码:

from PyQt5 import QtCore, QtGui, QtWidgets, QtWebEngineWidgets
class 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 QtWebEngineWidgets

if __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_())

如何才能禁用 Access-Control-Allow-Origin？

您可以尝试启用LocalContentCanAccessRemoteUrls WebAttribute :

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    settings = QtWebEngineWidgets.QWebEngineSettings.defaultSettings()
    settings.setAttribute(QtWebEngineWidgets.QWebEngineSettings.LocalContentCanAccessRemoteUrls, True)
    ...
