Android + Cloudant + CouchBase =错误404

Question

我正在Android上使用CouchBase Lite，并想连接到Cloudant上的在线数据库。 我有一些代码，但无法正常工作：

public class MainActivity extends ActionBarActivity {
final String TAG = "CouchBase";
Manager manager;
String dbname = "foimess";
Database database;
URL syncUrl;
public static final String SYNC_URL = "https://drmenko.cloudant.com/";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    try {
        manager = new Manager(new AndroidContext(this), Manager.DEFAULT_OPTIONS);
        Log.d (TAG, "Manager created");
    } catch (IOException e) {
        Log.e(TAG, "Cannot create manager object");
        return;
    }

    if (!Manager.isValidDatabaseName(dbname)) {
        Log.e(TAG, "Bad database name");
        return;
    }

    try {
        database = manager.getDatabase(dbname);
        Log.d (TAG, "Database created");
    } catch (CouchbaseLiteException e) {
        Log.e(TAG, "Cannot get database");
        return;
    }

        try {
            syncUrl = new URL(SYNC_URL + dbname);
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        Replication push = database.createPushReplication(syncUrl);
        Replication pull = database.createPullReplication(syncUrl);
        pull.setContinuous(true);
        push.setContinuous(true);
        com.couchbase.lite.auth.Authenticator auth = new BasicAuthenticator("user", "pass");
        push.setAuthenticator(auth);
        pull.setAuthenticator(auth);

        push.addChangeListener(new Replication.ChangeListener() {
            @Override
            public void changed(Replication.ChangeEvent event) {
                // will be called back when the push replication status changes
            }
        });
        pull.addChangeListener(new Replication.ChangeListener() {
            @Override
            public void changed(Replication.ChangeEvent event) {
                // will be called back when the pull replication status changes
            }
        });
        push.start();
        pull.start();


}

我在LogCat中收到此消息：

我究竟做错了什么？ 我在代码中或服务器上缺少某些内容吗？

Answer 1

404的第一个URL https://drmenko.cloudant.com/foimess/_session不正确-它应该是https://drmenko.cloudant.com/_session 。 这可能意味着没有进一步的请求被正确认证。
