Access token to access private ArcGIS enterprise contents

Fer

Hi,

We are trying to access some private layers stored in our ArcGIS enterprise hosting. The examples provided don’t seem to work, so we implemented our own method to generate and retrieve the token using OAuth 2.0. However even with the token I cannot access the private layers.

I tried to set the token parameter in this way (see https://developers.arcgis.com/documentation/mapping-apis-and-services/security/):

 

var layer_1 = new Esri.GameEngine.Layers.ArcGISImageLayer("https://<LOCATION_SERVICE_URL>?token=<ACCESS_TOKEN>", “UN_Map_Imagery", 1.0f, true, "");
arcGISMap.Layers.Add(layer_1);

 

Or putting the token as API key like that:

 

var layer_1 = new Esri.GameEngine.Layers.ArcGISImageLayer("<my rest service>", “UN_Map_Imagery", 1.0f, true, "<access_token>");
arcGISMap.Layers.Add(layer_1);

 

 

But none of these methods work. From the log, when I am trying to access the layer I am always getting:  Error (Propagated error.)

Any suggestions?

 

Many thanks,

Ferdinando

Hi Ferdinando, thank you for reaching out.
Appending the token to the service URL is not a valid workflow. Using the token you have, you can construct a credential in code. I recommend trying the following.

var credential = new ArcGISOAuthAuthorizationCredential("<ACCESSTOKEN>", DateTimeOffset.MaxValue, "<REFRESHTOKEN>");

var authenticationConfiguration = new ArcGISOAuthAuthenticationConfiguration("<CLIENTID>".Trim(), "<CLIENTSECRET>", "<REDIRECTURI>".Trim(), credential);
	
ArcGISAuthenticationManager.AuthenticationConfigurations.Add("<SERVICEURL>", authenticationConfiguration);

 
Also, I am curious why the provided OAuth sample did not work with your data. ArcGISOAuthAuthenticationConfiguration has a AuthorizationCredentialIssuedEvent. It might be worth checking if this event fires when attempting to authenticate using the pattern in the OAuth sample.

I hope this helps, please let me know if you have further questions.
