Sample viewer app

Access a web map that is secured with ArcGIS token-based authentication.

Use case

Allows you to access a secure service with the convenience and security of ArcGIS token-based authentication. For example, rather than providing a user name and password every time you want to access a secure service, you only provide those creditials initially to obtain a token which then can be used to access secured resources.

How to use the sample

Once you launch the app, you will be challenged for an ArcGIS Online login to view the protected map service. Enter a user name and password for this resources. In this case, the username is user1 and the password is also user1.

How it works

  1. Create an ArcGISMapImageLayer passing in the URL to a map service that is secured with token-based authentication.
  2. Append the map image layer to the operational layers to display the map.
