c# - 如何在 C# 中的 SSH 服务器上运行命令？

Question

我需要使用 C# 代码执行此操作:

1. 在后台打开 putty.exe(这就像一个 cmd 窗口)
2. 使用 IP 地址登录远程主机
3. 输入用户名和密码
4. 一个接一个地执行几个命令。
5. 运行另一个命令得到响应，告诉我之前运行的命令已成功执行

所以我试着这样做:

ProcessStartInfo proc = new ProcessStartInfo() 
{
     FileName = @"C:\putty.exe",
     UseShellExecute = true, //I think I need to use shell execute ?
     RedirectStandardInput = false,
     RedirectStandardOutput = false,
     Arguments = string.Format("-ssh {0}@{1} 22 -pw {2}", userName, hostIP, password)
     ... //How do I send commands to be executed here ?
};
Process.Start(proc);

你可以试试 https://github.com/sshnet/SSH.NET .有了这个，你根本不需要腻子或 window 。您也可以获得回复。它会看起来……像这样。

SshClient sshclient = new SshClient("172.0.0.1", userName, password);    
sshclient.Connect();
SshCommand sc= sshclient .CreateCommand("Your Commands here");
sc.Execute();
string answer = sc.Result;

编辑:另一种方法是使用 shellstream。

像这样创建一个 ShellStream:

ShellStream stream = sshclient.CreateShellStream("customCommand", 80, 24, 800, 600, 1024);

然后你可以使用这样的命令:

  public StringBuilder sendCommand(string customCMD)
    {
        StringBuilder answer;
        
        var reader = new StreamReader(stream);
        var writer = new StreamWriter(stream);
        writer.AutoFlush = true; 
        WriteStream(customCMD, writer, stream);
        answer = ReadStream(reader);
        return answer;
    }

private void WriteStream(string cmd, StreamWriter writer, ShellStream stream)
    {
        writer.WriteLine(cmd);
        while (stream.Length == 0)
        {
            Thread.Sleep(500);
        }
    }

private StringBuilder ReadStream(StreamReader reader)
    {
        StringBuilder result = new StringBuilder();

        string line;
        while ((line = reader.ReadLine()) != null)
        {
            result.AppendLine(line);
        }
        return result;
    }
