In auth/src/main/java/com/google/firebase/quickstart/AuthSnippets.java https://github.com/firebase/quickstart-java/pull/15#discussion_r153664804 :
- public static void setCustomUserClaims(
- String uid) throws InterruptedException, ExecutionException {
- // [START set_custom_user_claims]
- // Set admin privilege on the user corresponding to uid.
- Map<String, Object> claims = new HashMap<>();
- claims.put("admin", true);
- FirebaseAuth.getInstance().setCustomClaimsAsync(uid, claims).get();
- // The new custom claims will propagate to the user's ID token the
- // next time a new one is issued.
- // [END set_custom_user_claims]
- String idToken = "id_token";
- // [START verify_custom_claims]
- // Verify the ID token first.
- FirebaseToken decoded = FirebaseAuth.getInstance().verifyIdTokenAsync(idToken).get();
- if (Boolean.TRUE.equals(decoded.getClaims().get("admin"))) {
getClaims() returns a Map<String, Object>. So when querying the map we need to deal with possible null values (if the key does not exist), and the returned value not being boolean. Boolean.TRUE.equals() provides a one-liner that deals with both cases.
