Example 1 with Cors

use of org.keycloak.services.resources.Cors in project keycloak by keycloak.

the class TokenEndpoint method tokenExchange.

public Response tokenExchange() {
    ProfileHelper.requireFeature(Profile.Feature.TOKEN_EXCHANGE);
    event.detail(Details.AUTH_METHOD, "token_exchange");
