Désactiver QWebEngineView accès à QFileDialog

Question

J'essaie de développer un navigateur qui permet les téléchargements, mais désactive tous les moyens de télécharger quelque chose sur Internet. J'ai développé le navigateur avec PyQt5 mais je n'arrive pas à comprendre comment désactiver le FileDialog (ex en cliquant sur ajouter une pièce jointe dans Gmail). J'ai déjà mis en place des paramètres désactivant des choses comme LocalContentCanAccessRemoteUrls et LocalContentCanAccessFileUrls parmi d'autres drapeaux. J'ai également sous-classé QWebEnginePage et modifié la fonction "chooseFile" sans aucune chance. Ci-dessous vous pouvez voir mon code, here you can find the UI and resources file.

# Python import 
import sys 

# PYQT Imports 
from PyQt5 import QtCore, QtGui, QtWidgets, QtWebEngineWidgets 
# from QtWebEngineWidgets.QWebEngineView import QWebEngineView 

# UI IMPORT 
import UI_Sailor 


class WebPage(QtWebEngineWidgets.QWebEnginePage): 
    def chooseFile(self, frame=None, path=''): 
     print ('Called this') 
     return 


class Sailor(QtWidgets.QMainWindow, UI_Sailor.Ui_Sailor): 

    def __init__(self): 
     super(self.__class__, self).__init__() 
     self.setupUi(self) 
     # self.setWindowIcon(QtGui.QIcon(':/Icons/Icons/Icon_Small.png')) 
     self.setWindowTitle('Sailor - 1.0.0') 

     glob_settings = QtWebEngineWidgets.QWebEngineSettings.globalSettings() 
     self.setWebSettings(glob_settings) 

     self.create_connections() 

    def setWebSettings(self, object_settings): 
     print ('Called') 
     # Global web settings 
     object_settings.setAttribute(1, True) # JaveScript 
     object_settings.setAttribute(3, False) # Clipboard (JaveScript) 
     object_settings.setAttribute(5, False) # Local Storage 
     object_settings.setAttribute(6, False) # LocalContentCanAccessRemoteUrls 
     object_settings.setAttribute(7, False) # XSSAuditingEnabled 
     object_settings.setAttribute(9, False) # LocalContentCanAccessFileUrls 
     object_settings.setAttribute(11, True) # ScrollAnimatorEnabled 
     object_settings.setAttribute(14, True) # FullScreenSupportEnabled 

     # Check that the options are applied 
     # print (object_settings.testAttribute(1)) # JaveScript 
     # print (object_settings.testAttribute(2)) # JaveScript 
     # print (object_settings.testAttribute(3)) # Clipboard (JaveScript) 
     # print (object_settings.testAttribute(5)) # Local Storage 
     # print (object_settings.testAttribute(6)) # LocalContentCanAccessRemoteUrls 
     # print (object_settings.testAttribute(7)) # XSSAuditingEnabled 
     # print (object_settings.testAttribute(9)) # LocalContentCanAccessFileUrls 
     # print (object_settings.testAttribute(11)) # ScrollAnimatorEnabled 
     # print (object_settings.testAttribute(14)) # FullScreenSupportEnabled 

    def create_connections(self): 
     self.TXT_Address.returnPressed.connect(self.web_load_url) 
     # self.WEB_View.urlChanged.connect(self.debug) 

    def web_load_url(self): 
     # Creates the proper url 
     url_base = str(self.TXT_Address.text()) 
     url_clean = self.url_handler(url_base) 
     # Loads the url 
     # self.WEB_View.setUrl(QtCore.QUrl(url_clean)) 
     self.WEB_View.setPage(WebPage(self.WEB_View)) 
     self.WEB_View.load(QtCore.QUrl(url_clean)) 

     self.setWebSettings(self.WEB_View.settings()) 


    def debug(self): 
     print ('called') 


    def url_handler(self, url): 
     if 'http' not in url: 
      return 'http://{}'.format(url) 


if __name__ == '__main__': 
    app = QtWidgets.QApplication(sys.argv) 
    form = Sailor() 
    form.show() 
    app.exec_()

Vous avez défini la mauvaise méthode dans la classe WebPage. Il semble que vous ayez utilisé la signature de la classe QtWebKit.QWebPage, plutôt que celle de la classe QWebEnginePage. Voici un exemple de travail minimal:

import sys 
from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets 

class WebPage(QtWebEngineWidgets.QWebEnginePage): 
    def chooseFiles(self, mode, oldfiles, mimetypes): 
     print('Called this') 
     return [] 

class Window(QtWebEngineWidgets.QWebEngineView): 
    def __init__(self): 
     super(Window, self).__init__() 
     self.setPage(WebPage(self)) 
     self.setHtml('<input type="file">') 

if __name__ == '__main__': 

    app = QtWidgets.QApplication(sys.argv) 
    window = Window() 
    window.setGeometry(600, 100, 400, 200) 
    window.show() 
    sys.exit(app.exec_())
