Retrieving thumbnail path from portal item

TomGeo — Mon, 18 Apr 2022 15:20:09 GMT

I want to retrieve the thumbnail path of a layer at our enterprise portal, and while that is straight forward I have the challenge, that I cannot use the path returned

https://our-portal.com/portal/sharing/rest/content/items/580d1a480196436fb7e2e1170466ba94/info/thumbnail/thumbnail1548171039005.png

Because there I am getting an Error 403 (You do not have permissions to access this resource or perform this operation.).

The layer itself I can create using

string curService = $"https://our-portal.com/portal/home/item.html?id={guid}"; await QueuedTask.Run(() => LayerFactory.Instance.CreateLayer(new Uri(curService, UriKind.Absolute), activeMapView.Map, 0));

How can I connect to the thumbnail?

The solution to get to the thumbnail is to add the token of your current session to the thumbnail path.

ArcGISPortal activePortal = ArcGISPortalManager.Current.GetActivePortal(); string sessionToken = activePortal.GetToken(); _thumbnail = $"{portalItem.ThumbnailPath}?token={_portalToken}";
