Authorization Example

Start topaz

// create a channel that has the connection details
ManagedChannel channel = new ChannelBuilder()
        .withHost("localhost")
        .withPort(8282)
        .withInsecure(true)
        .build();

// create authz client
AuthorizerClient authzClient = new AuthzClient(channel);

// identity context contains information abou the user that requests access to some resource
IdentityCtx identityCtx = new IdentityCtx("rick@the-citadel.com", IdentityType.IDENTITY_TYPE_SUB);

// contains information about the policy we want to check for the provided identity
PolicyCtx policyCtx = new PolicyCtx("todo", "todo", "todoApp.DELETE.todos.__id", new String[]{"allowed"});

// check if the identity is allowed to perform the action
List<Decision> decisions = authzClient.is(identityCtx, policyCtx);
authzClient.close();

decisions.forEach(decision -> {
    String dec = decision.getDecision();
    boolean isAllowed =  decision.getIs();
    System.out.println("For decision [" + dec + "] the answer was [" + isAllowed + "]");
});
