Question

我正在使用此SSH.NET客户端https://github.com/sshnet/SSH.NET/和MongoDB C＃最新客户端。根据{{3}}，我尝试将SSHStream注入MongoDB客户端设置。我的SSH连接成功。但是我无法通过SSH与MongoDB建立连接。

   static void Main(string[] args)
    {
        MongoClientSettings settings = new MongoClientSettings
        {
            ClusterConfigurator = cb =>
            {
                cb.RegisterStreamFactory(CustomStreamFac);
            }   
        };
        MongoClient mongoClient = new MongoClient(settings);
        IMongoDatabase db = mongoClient.GetDatabase("testdb");
        var collections = db.ListCollections();
    }

    public static IStreamFactory CustomStreamFac(IStreamFactory istreamfac)
    {

        Stream stream = istreamfac.CreateStream();
        return istreamfac;
    }

public static class Extension
{
    public static Stream CreateStream(this IStreamFactory isf)
    {
        ConnectionInfo conn = new ConnectionInfo(hostname, port, username, new PrivateKeyAuthenticationMethod(username, new PrivateKeyFile(keyfile, password)));
        SshClient cli = new SshClient(conn);
        cli.Connect();
        ShellStream shellStream = null;
        shellStream = cli.CreateShellStream("Command", 0, 0, 0, 0, 1024);            
        return shellStream;
    }
}

感谢您的帮助。

您可以使用以下代码启动SSH客户端。

ConnectionInfo conn = new ConnectionInfo(SSHServerHost, SSHServerPort,SSHServerUserName, new PrivateKeyAuthenticationMethod(SSHServerUserName, new PrivateKeyFile(PrivateKeyPath,SSHServerPassword)));
SshClient = new SshClient(conn);
SshClient.Connect();
ForwardedPortLocal forwardedPortLocal = new ForwardedPortLocal("127.0.0.1",5477,MongoDBHost, MongoDBPort);
SshClient.AddForwardedPort(forwardedPortLocal);
forwardedPortLocal.Start();

现在SSH客户端会将localhost端口5477转发到远程MongoDB数据库服务器。

MongoClient可用于与MongoDB Server通信，主机为localhost，端口为5477。

请参考下面的代码片段以连接MongoDB Server。

MongoConnection connection = new MongoConnection();
MongoDBClientConnection clientConnection = new MongoDBClientConnection(){MongoDBClient = new MongoClient( MongoClientSettings settings = new MongoClientSettings
            {
                Server = new MongoServerAddress(localhost, 5477)                
            };)}        
connection.MongoDBServer = clientConnection.MongoDBClient.GetServer();
connection.MongoDBServer.Connect();

以上代码将使用SSH隧道连接到MongoDB Server。
