Spyemcached에서 Redis Cloud Memcached에 인증하는 방법은 무엇입니까?

Question

Redis Cloud Memcached에 연결하려고하는데 오류가 발생합니다 (아래). apps.redislabs.com 인터페이스에서 사용자 이름, 비밀번호, 호스트 및 포트가 올바른지 확인했습니다. SASL을 비활성화하고 인증되지 않은 상태로 연결하면 연결할 수 있습니다.

어떻게 진단 할 수 있습니까?

(spymemcached 2.11.6를 사용.)

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));

이 AuthDescriptior 선언에 "CRAM-MD5"을 잃게됩니다.

내 테스트의 다음 작품 : (사용자가 통과 및 URL 제거)

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);
