RESTEasy client framework authentication credentials

Question

RESTEasy (a JAX-RS implementation) has a nice client framework, eg:

ServiceApi client = ProxyFactory.create(ServiceApi.class, baseUri);

How

Answer 1

Maybe something like this (with RestEasy 2.3.1) :

//(...imports...)
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.impl.client.DefaultHttpClient;
import org.jboss.resteasy.client.ClientRequest;
import org.jboss.resteasy.client.ClientResponse;
import org.jboss.resteasy.client.core.executors.ApacheHttpClient4Executor;

//(...code...)
private static final String ENDPOINT = "the_rest_endpoint_here";

String username = "";
String password = "";

DefaultHttpClient client = new DefaultHttpClient();
client.getCredentialsProvider().setCredentials(AuthScope.ANY,
                        new UsernamePasswordCredentials(username, password));
ApacheHttpClient4Executor executer = new ApacheHttpClient4Executor(client);

ClientRequest req = new ClientRequest(ENDPOINT, executer);

ClientResponse res = req.get(String.class);
System.out.println(res.getEntity());
res.close();

...or with RestEasy 3.0.18

//(...imports...)
import javax.ws.rs.core.Response;
import org.jboss.resteasy.client.jaxrs.BasicAuthentication;
import org.jboss.resteasy.client.jaxrs.ResteasyClient;
import org.jboss.resteasy.client.jaxrs.ResteasyClientBuilder;
import org.jboss.resteasy.client.jaxrs.ResteasyWebTarget;

//(...code...)
private static final String ENDPOINT = "the_rest_endpoint_here";

String usertoken = "";
String password = "";

//with proxy(comment this if not using)
ResteasyClient client = new ResteasyClientBuilder()
            .defaultProxy("my_proxy", 8080, "http")
            .build();

ResteasyWebTarget target = client.target(ENDPOINT);
target.register(new BasicAuthentication(usertoken, password));

Response response = target.request().get();
System.out.println(response.readEntity(String.class));
response.close();
