wpf - SSH.NET 实时命令输出监控

Question

有一个长时间运行的脚本 script.sh在远程 Linux 机器上。我需要启动它并实时监控它的事件。事件期间的脚本可能会输出到 stdout和 stderr .我正在寻找一种方法来捕获两个流。

我使用人次SSH.NET上传script.sh并启动它，因此很高兴看到与此库相关的解决方案。在我看来，完美的解决方案是新方法:

var realTimeScreen= ...;

var commandExecutionStatus = sshClient.RunCommandAsync(
    command: './script.sh',
    stdoutEventHandler: stdoutString => realTimeScreen.UpdateStdout(stdString)
    stderrEventHandler: stderrString => realTimeScreen.UpdateStderr(stderrString));
...
commandExecutionStatus.ContinueWith(monitoringTask =>
{
    if (monitoringTask.Completed)
    {
        realTimeScreen.Finish();
    }
});

使用 SshClient.CreateCommand方法。它返回 SshCommand实例。SshCommand类(class)有ExtendedOutputStream返回带有 stdout 和 stderr 的流的属性。
见 SshCommandTest.cs :

public void Test_Execute_ExtendedOutputStream()
{
    var host = Resources.HOST;
    var username = Resources.USERNAME;
    var password = Resources.PASSWORD;

    using (var client = new SshClient(host, username, password))
    {
        #region Example SshCommand CreateCommand Execute ExtendedOutputStream

        client.Connect();
        var cmd = client.CreateCommand("echo 12345; echo 654321 >&2");
        var result = cmd.Execute();

        Console.Write(result);

        var reader = new StreamReader(cmd.ExtendedOutputStream);
        Console.WriteLine("DEBUG:");
        Console.Write(reader.ReadToEnd());

        client.Disconnect();

        #endregion

        Assert.Inconclusive();
    }
}
