How to enable Location access

[schandra09net]

Hello Team,

1. I am currently using Cef 91.1.230 In my application development with C# and WPF.
2. Tried loading a page in my CefBrowser with link "https://earth.google.com/web/@0,0,0a,22251752.77375655d,35y,0h,0t,0r" and clicked on Location icon on bottom right corner.
3. Got an warning that "Location servies should be enabled"

Possible solutions tried:

1. Followed couple of articles to use IGeoLocationHandler but unfortunately which is not there/removed in v91.
2. Tried using "ViewControl.WebBrowser.GetDevToolsClient().Browser.GrantPermissionsAsync(new PermissionType[] { PermissionType.Geolocation });" but getting an error "CefSharp.DevTools.DevToolsClientException: {"code":-32000,"message":"Browser context management is not supported."}'

How to enable the "Location services", can any one help with this.

Geolocation is not supported. Upstream support was removed.

Another option is to mock the relevant geolocation APIs in JavaScript yourself like mentioned in https://magpcss.org/ceforum/viewtopic.php?f=6&t=17432

Here is an example, Google Earth uses watchPosition whereas Google Maps uses getCurrentPosition:

browser.ExecuteScriptAsyncWhenPageLoaded(@"
navigator.permissions.query = options => {
  return Promise.resolve({
    state: 'granted'
  });
};
navigator.geolocation.getCurrentPosition = (success, error, options) => {
  success({
    coords: {
      latitude: -33.854477,
      longitude: 151.234738,
      accuracy: 10,
      altitude: null,
      altitudeAccuracy: null,
      heading: null,
      speed: null
    },
    timestamp: Date.now()
  });
};
navigator.geolocation.watchPosition = (success, error, options) => {
  success({
    coords: {
      latitude: -33.854477,
      longitude: 151.234738,
      accuracy: 49,
      altitude: null,
      altitudeAccuracy: null,
      heading: null,
      speed: null
    },
    timestamp: Date.now()
  });
  return 0;
};
", oneTime: false);

See https://developer.mozilla.org/docs/Web/API/Geolocation for the JavaScript APIs..

@campersau : Thank you so much again, now it navigate to fixed custom location as specified in Longitude and Latitude after added the script to the browser in IsBrowserInitializedChanged event.

Thanks Amigo.
