Restlet Auth

Example For Restlet Auth 

1. Create a Restlet Server 

package server;

import org.restlet.Application;

import org.restlet.Component;

import org.restlet.data.Protocol;

public class TestServer extends Application {

public static void main(String[] args) throws Exception {

Component component = new Component();

component.getServers().add(Protocol.HTTP, 8182);

component.getDefaultHost().attach("/trace", Part3.class); 

component.start();

}

}

2. Create a Restlet Resource

package server;

import org.restlet.Request;

import org.restlet.data.MediaType;

import org.restlet.representation.Representation;

import org.restlet.representation.StringRepresentation;

import org.restlet.resource.Get;

import org.restlet.resource.ServerResource;

public class RestletResource extends ServerResource {  

@Get

public Representation doPost(Representation entity) {

Request request = getRequest();

Check check = new Check();

String result = check.authCheck(request);

if(result.equals("success")){

return new StringRepresentation("Success : ", MediaType.TEXT_PLAIN);

}

else{

return new StringRepresentation("Fail : ", MediaType.TEXT_PLAIN);

}

}

}  

3. Create a Auth Check method

import org.restlet.Request;

import org.restlet.data.ChallengeResponse;

public class Check {

public String authCheck(Request request) {

String result;

ChallengeResponse challengeResponse = request.getChallengeResponse();

if (challengeResponse == null) {

throw new RuntimeException("not authenticated");

}

String userName = challengeResponse.getIdentifier();

System.out.println("Identifier :" + userName);

String password = new String(challengeResponse.getSecret());

System.out.println("Secret" + password);

                 /*

* Here you can check the username and password. I am considering 'Dev' and 'Dev123'

*/

if (userName.equals("dev") && password.equals("Dev123")) {

result = "success";

} else {

result = "fail";

}

return result;

}

}

4. Restlet Client

import org.restlet.data.ChallengeScheme;
import org.restlet.resource.ClientResource;
import org.restlet.resource.ResourceException;

public class TestClient {

public static void main(String[] args) throws Exception {
ClientResource resource = new ClientResource("http://localhost:8182/trace");
resource.setChallengeResponse(ChallengeScheme.HTTP_BASIC, "dev", "Dev123");
// Send the first request with unsufficient authentication.
try {
System.out.println(resource.get(String.class));
} catch (ResourceException re) {
re.printStackTrace();
}

}
}
