要在RESTlet 2.0中进行基本身份验证（自从您提到以来，我假设您正在使用2.0
ServerResource），则需要使用
ChallengeAuthenticator。如果配置了，
optional =true则只有在您调用时才需要身份验证
ChallengeAuthenticator.challenge()。
您可以使用
authenticate()方法创建应用程序，并在需要访问要保护的资源时调用此方法：
应用：
package example;import org.restlet.*;import org.restlet.data.ChallengeScheme;import org.restlet.routing.Router;import org.restlet.security.*;public class ExampleApp extends Application { private ChallengeAuthenticator authenticatior; private ChallengeAuthenticator createAuthenticator() { Context context = getContext(); boolean optional = true; ChallengeScheme challengeScheme = ChallengeScheme.HTTP_BASIC; String realm = "Example site"; // MapVerifier isn't very secure; see docs for alternatives MapVerifier verifier = new MapVerifier(); verifier.getLocalSecrets().put("user", "password".toCharArray()); ChallengeAuthenticator auth = new ChallengeAuthenticator(context, optional, challengeScheme, realm, verifier) { @Override protected boolean authenticate(Request request, Response response) { if (request.getChallengeResponse() == null) { return false; } else { return super.authenticate(request, response); } } }; return auth; } @Override public Restlet createInboundRoot() { this.authenticatior = createAuthenticator(); Router router = new Router(); router.attach("/user", UserResource.class); authenticatior.setNext(router); return authenticatior; } public boolean authenticate(Request request, Response response) { if (!request.getClientInfo().isAuthenticated()) { authenticatior.challenge(response, false); return false; } return true; }}资源：
package example;import org.restlet.data.MediaType;import org.restlet.representation.EmptyRepresentation;import org.restlet.representation.Representation;import org.restlet.representation.StringRepresentation;import org.restlet.resource.ServerResource;public class UserResource extends ServerResource { @Override public Representation get() { ExampleApp app = (ExampleApp) getApplication(); if (!app.authenticate(getRequest(), getResponse())) { // Not authenticated return new EmptyRepresentation(); } // Generate list of users // ... } @Override public Representation post(Representation entity) { // Handle post // ... }}
