Couchbase.Lite无法复制

Question

我正在尝试通过C＃Couchbase.Lite库复制Couchbase Enterprise数据库。通过SSH隧道访问同步网关。即使我按照文档中的说明使用它，复制也无法正常进行。

这些是Couchbase Lite日志：

这是C＃代码：

var database = new Database("foo");

var targetUri = new Uri("ws://localhost:4984/foo");
var gateway = new URLEndpoint(targetUri);
var replicationConfig = new ReplicatorConfiguration(database, gateway)
{
    ReplicatorType = ReplicatorType.PushAndPull,
    Authenticator = new BasicAuthenticator("user", "password")
};

var replicator = new Replicator(replicationConfig);
replicator.AddChangeListener((sender, args) =>
{
    var activity = args.Status.Activity;
    var error = args.Status.Error;

    if (error == null)
    {
        Console.WriteLine($"Database replicator activity changed to {activity}");
    }
    else
    {
        Console.WriteLine($"Database replicator activity changed to {activity}; last exception: {error}");
    }
});
replicator.Start();

如日志中所示，Couchbase Lite客户端无法访问Sync Gateway。确认可以从尝试复制的设备通过网络访问Sync Gateway。

[您还提到了“通过SSH隧道到达Sync Gateway”-没有理由您只应通过SSH隧道访问Sync Gateway。因此，请确保您的同步网关的公共端口可直接访问。复制通过已认证的公共端口进行。但是，建议不要将管理端口直接暴露给外部网络。
