【问题讨论】：
【参考方案1】：您必须使用featurePermissionRequested 信号，该信号将在每次浏览器需要使用某些资源的权限时发出，然后打开一个对话框，如果用户接受或不接受，则使用setFeaturePermission() 接受或拒绝该功能：
from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets
class WebEnginePage(QtWebEngineWidgets.QWebEnginePage):
def __init__(self, parent=None):
super(WebEnginePage, self).__init__(parent)
self.featurePermissionRequested.connect(self.handleFeaturePermissionRequested)
@QtCore.pyqtSlot(QtCore.QUrl, QtWebEngineWidgets.QWebEnginePage.Feature)
def handleFeaturePermissionRequested(self, securityOrigin, feature):
title = "Permission Request"
questionForFeature =
QtWebEngineWidgets.QWebEnginePage.Geolocation : "Allow feature to access your location information?",
QtWebEngineWidgets.QWebEnginePage.MediaAudioCapture : "Allow feature to access your microphone?",
QtWebEngineWidgets.QWebEnginePage.MediaVideoCapture : "Allow feature to access your webcam?",
QtWebEngineWidgets.QWebEnginePage.MediaAudioVideoCapture : "Allow feature to lock your mouse cursor?",
QtWebEngineWidgets.QWebEnginePage.DesktopVideoCapture : "Allow feature to capture video of your desktop?",
QtWebEngineWidgets.QWebEnginePage.DesktopAudioVideoCapture: "Allow feature to capture audio and video of your desktop?"
question = questionForFeature.get(feature)
if question:
question = question.format(feature=securityOrigin.host())
if QtWidgets.QMessageBox.question(self.view().window(), title, question) == QtWidgets.QMessageBox.Yes:
self.setFeaturePermission(securityOrigin, feature, QtWebEngineWidgets.QWebEnginePage.PermissionGrantedByUser)
else:
self.setFeaturePermission(securityOrigin, feature, QtWebEngineWidgets.QWebEnginePage.PermissionDeniedByUser)
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.browser = QtWebEngineWidgets.QWebEngineView()
page = WebEnginePage(self.browser)
self.browser.setPage(page)
self.browser.load(QtCore.QUrl("https://developers.google.com/maps/documentation/javascript/examples/map-geolocation"))
self.setCentralWidget(self.browser)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.showMaximized()
sys.exit(app.exec())
【讨论】：
非常感谢您的回复，但每次都拒绝许可。我的意思是当我单击“是”时允许位置权限显示错误。 serialnmea：未找到已知的 GPS 设备。通过 QT_NMEA_SERIAL_PORT 指定 COM 端口。创建 Geoclue 客户端界面失败。 Geoclue 错误：org.freedesktop.DBus.Error.Disconnected @MuhammadAzeem 这是个问题，因为你需要一个位置提供者，现在 Qt 使用 geoclue 或 geoclue2，你的操作系统是什么？ @MuhammadAzeem 如果您使用 ubuntu 测试安装：sudo apt-get install libgeoclue-dev geoclue
我使用的是 Windows 10 64 位操作系统
@MuhammadAzeem 根据docs：目前该 API 支持 Android、ios、macOS、Linux（使用 GeoClue 版本 0.12.99）、Windows（使用 GPS 接收器暴露为提供 NMEA 语句的串口），以及 WinRT（使用 Windows.Devices.Geolocation），即需要通过串口连接 GPS。以上是关于位置权限弹出窗口的主要内容，如果未能解决你的问题，请参考以下文章
