Comment s'authentifier auprès de Redis Cloud Memcached à partir de Spymemcached?

Question

J'essaye de me connecter à Redis Cloud Memcached mais je reçois une erreur (ci-dessous). J'ai vérifié que le nom d'utilisateur, le mot de passe, l'hôte et le port sont corrects dans l'interface apps.redislabs.com. Je peux me connecter si je désactive SASL et me connecte sans authentification.

Comment puis-je diagnostiquer cela?

(à l'aide spymemcached 2.11.6.)

import net.spy.memcached.auth.*; 
import net.spy.memcached.*; 
... 
List<InetSocketAddress> addresses = Collections.singletonList(addr); 
AuthDescriptor ad = new AuthDescriptor(new String[] { "CRAM-MD5", "PLAIN" }, 
     new PlainCallbackHandler(user, password)); 
MemcachedClient mc = new MemcachedClient(new ConnectionFactoryBuilder() 
     .setProtocol(ConnectionFactoryBuilder.Protocol.BINARY) 
     .setAuthDescriptor(ad).build(), 
AddrUtil.getAddresses(host + ":" + port));

perdent la "CRAM-MD5" dans votre déclaration AuthDescriptior.

Les travaux suivants dans mes tests: (utilisateur, passer, et url supprimé)

AuthDescriptor ad = new AuthDescriptor(new String[] {"PLAIN"}, new PlainCallbackHandler(user, pass)); 
MemcachedClient mc = null; 
    try { 
     mc = new MemcachedClient(
     new ConnectionFactoryBuilder() 
      .setProtocol(ConnectionFactoryBuilder.Protocol.BINARY) 
      .setAuthDescriptor(ad).build(), 
     AddrUtil.getAddresses(host + ":" + port)); 
    } catch (IOException e) { 
     // handle exception 
    } 
mc.set("foo", 0, "bar"); 
String value = (String) mc.get("foo"); 
System.out.println(value);
