RESTEasy客户端框架身份验证凭据

Question

RESTEasy（一个JAX-RS实现）有一个不错的客户端框架，例如：

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

如何向此客户端提供HTTP身份验证凭据？

Answer 1

jnorris的答案使用了一些已经废弃的类。下面是一个更新后使用非废弃类的方法。

    import org.apache.http.HttpStatus;
    import org.apache.http.auth.Credentials;
    import org.apache.http.auth.UsernamePasswordCredentials;
    import org.apache.http.impl.client.DefaultHttpClient;
    ...
    DefaultHttpClient httpClient = new DefaultHttpClient();

    Credentials credentials = new UsernamePasswordCredentials(userName,
            password);
    httpClient.getCredentialsProvider().setCredentials(
            org.apache.http.auth.AuthScope.ANY, credentials);

    ClientExecutor clientExecutor = new ApacheHttpClient4Executor(
            httpClient);
    proxy = ProxyFactory
            .create(UserAccessProxy.class, host, clientExecutor);

Answer 2

通过使用ClientExecutor可以提供凭证。

   Credentials credentials = new UsernamePasswordCredentials(userId, password);
   HttpClient httpClient = new HttpClient();
   httpClient.getState().setCredentials(AuthScope.ANY, credentials);
   httpClient.getParams().setAuthenticationPreemptive(true);

   ClientExecutor clientExecutor = new ApacheHttpClientExecutor(httpClient);

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

也许可以像这样（使用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 = "<user_name>";
String password = "<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<String> res = req.get(String.class);
System.out.println(res.getEntity());
res.close();

...或者使用 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 = "<user_token>";
String password = "<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();
