Python PyQt 5.9中的OpenLayers地理定位

我已经实现了一个带有地理定位功能和按钮的网站

此网页在QwebEngineView(OSM地图)中显示良好。 网页已加载

def __init__(self, parent=None):
        super(MainGUI, self).__init__(parent)
        self.ui = uic.loadUi("GPS.ui", self)
        self.ui.w3View.load(QtCore.QUrl('file:///Map.html'))
所有原生OpenLayers按钮(放大和缩小)都工作正常

我创建了一个新的自定义按钮,在OpenLayers地图上显示我的地理位置

这是我用来定位我的功能:

var handleGeolocation = function() {

      var coordinates;
      var geolocation = new ol.Geolocation({
        projection: view.getProjection(),
        tracking: true
      });
      // handle geolocation error.
      geolocation.on('error', function (error) {
        var info = document.getElementById('info');
        info.innerHTML = error.message;
        info.style.display = '';
      });

      var accuracyFeature = new ol.Feature();
      geolocation.on('change:accuracyGeometry', function () {
        accuracyFeature.setGeometry(geolocation.getAccuracyGeometry());
      });

      var positionFeature = new ol.Feature();
      positionFeature.setStyle(new ol.style.Style({
        image: new ol.style.Circle({
          radius: 6,
          fill: new ol.style.Fill({
            color: '#3399CC'
          }),
          stroke: new ol.style.Stroke({
            color: '#fff',
            width: 2
          })
        })
      }));

      geolocation.once('change:position', function () {
        coordinates = geolocation.getPosition();
        positionFeature.setGeometry(coordinates ?
          new ol.geom.Point(coordinates) : null);
        map.getView().setCenter(coordinates);
        map.getView().setZoom(17);
      });

      new ol.layer.Vector({
        map: map,
        source: new ol.source.Vector({
          features: [accuracyFeature, positionFeature]
        })
      });
    }
我在的帮助下创建了按钮

整个网页如下所示:

在普通浏览器中,它工作正常,但在我的PyQt应用程序中却不行。 单击“自定义”按钮后,不会发生任何事情


我做错了什么或什么是不可能的?

添加以下行解决了我的问题:

    self.ui.w3View.page().featurePermissionRequested.connect(self.permissionRequested)

def permissionRequested(self, frame, feature):
    self.ui.w3View.page().setFeaturePermission(frame, feature, QtWebEngineWidgets.QWebEnginePage.PermissionGrantedByUser)

在post中找到并将其编辑为PyQt 5.9。

主要问题是启用权限,如果您在Firefox、Chrome等浏览器中运行,将显示一个弹出窗口,询问您是否接受地理位置权限

在这种情况下,它必须通过代码启用,为此,
QWebEnginePage
在每次需要授权时都会发出一个信号,它通过信号来实现这一点,我们将其连接到某个插槽,并使用该功能启用权限

注意:在linux中,我仍然无法使用GeoClude提供程序,错误消息如下:

未能设置地理线索定位要求。地理线索错误: org.qtproject.QtDBus.Error.InvalidObjectPath


你可以解释你所犯的错误或不想要的行为
    self.ui.w3View..page().featurePermissionRequested.connect(self.onFeaturePermissionRequested)

def onFeaturePermissionRequested(self, securityOrigin, feature):
    self.sender().setFeaturePermission(securityOrigin,
                                     QWebEnginePage.Geolocation,
