Check If Portal Connection Is Valid

sgn_GSI

Hello,

After creating a new instance of the ArcGISPortal class, is there a way to check if the connection is still valid? I see that I could check the ExpirationDate of the Credentials. However, that does not help for checking for the scenarios where the user's internet connection drops out or the server hosting their ArcGIS Enterprise is down. Thank you very much for your time.

I basically just ping the portal and see if I get a response.  I have this run in the background and it sets a flag that I check before doing something that requires a connection

public override async Task<bool> CheckIsConnectedAsync()
{
	try
	{
		var tokenUri = new Uri($"{ConnectionUrl}/sharing/rest?f=json");

		HttpClient client = new HttpClient { Timeout = TimeSpan.FromSeconds(7) };
		var result = await client.GetStringAsync(tokenUri);

		var jsonObject = JsonConvert.DeserializeObject<Dictionary<string, object>>(result);
            //just something I know is in the return json
		return jsonObject.ContainsKey("currentVersion");
	}
	catch ( TaskCanceledException )
	{
		//timeout - server down
		return false;
	}
	catch ( Exception )
	{
		//Can connect but server not fully up and running
		return false;
	}
}
