SharpSSh：SshExec 中的 RunCommand 始终返回空字符串

发布于 2024-09-06 15:24:13 字数 870 浏览 6 评论 0原文

当使用 SharpSSh 和 SshExec 类时，我无法让 RunCommand 工作，它总是返回一个空字符串。当我调试 SharpSsh 库时，当它尝试从流中读取命令时，它会返回 -1。当我在同一个库中使用 sftp 类时它可以工作，但该类不支持我需要的所有 ftp 命令。

这是一个标准示例，我也无法让它产生正确的结果

SshConnectionInfo input = Util.GetInput();
SshExec exec = new SshExec(input.Host, input.User);
if(input.Pass != null) exec.Password = input.Pass;
if(input.IdentityFile != null) exec.AddIdentityFile( input.IdentityFile );

Console.Write("Connecting...");
exec.Connect();
Console.WriteLine("OK");
while(true)
{
    Console.Write("Enter a command to execute ['Enter' to cancel]: ");
    string command = Console.ReadLine();
    if(command=="")break;
    string output = exec.RunCommand(command);                
    Console.WriteLine(output);
}
Console.Write("Disconnecting...");
exec.Close();
Console.WriteLine("OK");

关于如何让 RunCommand 函数运行某些命令有什么想法吗？感谢您的帮助:)

When Using SharpSSh and the SshExec class, I can't get the RunCommand to work, it always returns an empty string. When I debug the SharpSsh library it returns -1 when it tries to read the command from a stream. It works when I use the sftp class in the same library, but that class doesn't support all the ftp commands I need.

Here is a standard example, I can't get this to produce a correct result either

SshConnectionInfo input = Util.GetInput();
SshExec exec = new SshExec(input.Host, input.User);
if(input.Pass != null) exec.Password = input.Pass;
if(input.IdentityFile != null) exec.AddIdentityFile( input.IdentityFile );

Console.Write("Connecting...");
exec.Connect();
Console.WriteLine("OK");
while(true)
{
    Console.Write("Enter a command to execute ['Enter' to cancel]: ");
    string command = Console.ReadLine();
    if(command=="")break;
    string output = exec.RunCommand(command);                
    Console.WriteLine(output);
}
Console.Write("Disconnecting...");
exec.Close();
Console.WriteLine("OK");

Any ideas on how I can get the RunCommand function to run some commands?
Thanks for any help :)

要从 .RunCommand 获取标准输出和错误流，
我将重复我发布的答案： SharpSSH - SSHExec，运行命令，然后等待 5 秒获取数据！

您可能想尝试以下重载：

SshExec exec = new SshExec("192.168.0.1", "admin", "haha");
exec.Connect();
string stdOut = null;
string stdError = null;
exec.RunCommand("interface wireless scan wlan1 duration=5", ref stdOut, ref stdError);

Console.WriteLine(stdOut);
exec.Close();

如果他们的 API 执行其名称所暗示的功能，它应该将命令的标准输出放入 stdOut，将标准错误放入标准错误。

有关标准流的更多信息，请查看：http://en.wikipedia.org/wiki/Standard_streams

To get the standard output and error streams from .RunCommand,
I'll repeat the answer I posted to: SharpSSH - SSHExec, run command, and wait 5 seconds for data!

You may want to try the following overload:

SshExec exec = new SshExec("192.168.0.1", "admin", "haha");
exec.Connect();
string stdOut = null;
string stdError = null;
exec.RunCommand("interface wireless scan wlan1 duration=5", ref stdOut, ref stdError);

Console.WriteLine(stdOut);
exec.Close();

If their API does what the name implies, it should put the standard output of your command in stdOut and the standard error in stdError.
