Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Testing the Service. With BASIC auth, the browser caches the credentials until you close it - it won't constantly prompt you over and over.

However, cookies can be vulnerable to cross-site request forgery (CSRF), so you should make sure your cookies use SameSite=Strict. The payload can be read by the client and the integrity of the token can be easily checked by verifying its signature on the server.

If some methods or classes do not need authentication, simply do not annotate them: In the example shown above, the filter will be executed only for the mySecuredMethod(Long) method because it's annotated with @Secured. @ArjanTijms: I hear you; I was attempting to simplify what actually happens (and what. I had to point out that if you do not want to use the org.apache.commons.codec.binary.Base64 class and you would like to use the android Base64 class instead: import android.util.Base64;, you can replace the one line above with this: byte[] base64CredsBytes = Base64.encode(plainCredsBytes, Base64.DEFAULT); @jhadesdev Hi, this worked for me when performing a GET request.

Most apps that use a modern web framework will have one or more REST APIs. Create an enumeration and define the roles according to your needs: Change the @Secured name binding annotation created before to support roles: And then annotate the resource classes and methods with @Secured to perform the authorization. What Is Behind The Puzzling Timing of the U.S. House Vacancy Election In Utah? No, don't encode the username or password - this is all handled deep within the browser and Glassfish. Hopefully you can try this against different URLs where you can examine the header information in more detail. For the token identifier you could use UUID. Apart from Rest Assured, I used below libraries too to communicate with Resful services. Who are Vrisha and Bhringariti?
