Securely invoking the backend REST API

Now, open http://localhost:3000/ and click on the Public endpoint link. You will see a message saying Public message!. The public endpoint is not secured by Keycloak and can be invoked without an access token.

Next, let’s try the secured endpoint that is protected by Keycloak. Open http://localhost:3000/ again. This time, click on the Secured endpoint link. Now you will see a message saying Access denied. This request is not permitted since it requires a valid access token to invoke the endpoint.

Let’s now try to invoke the secured endpoint from the frontend. Open http://localhost:8000/ and click on Invoke Service. You will now see a message displayed saying Secret message!. If instead you get the message Access Denied, this is most likely caused by the user not having the myrole role.

When you click Invoke Service, the frontend sends an AJAX request to the backend service, including the access token in the request, which allows the backend to verify that the invocation is done on behalf of a user who has the required role to access the endpoint.

Stian Thorgersen

Stian Thorgersen started his career at Arjuna Technologies building a cloud federation platform, years before most companies were even ready for a single-vendor public cloud. He later joined Red Hat, looking for ways to make developers' lives easier, which is where the idea of Keycloak started. In 2013, Stian co-founded the Keycloak project with another developer at Red Hat. Today, Stian is the Keycloak project lead and is also the top contributor to the project. He is still employed by Red Hat as a senior principal software engineer focusing on identity and access management, both for Red Hat and for Red Hat's customers. In his spare time, there is nothing Stian likes more than throwing his bike down the mountains of Norway.
