c# - 使用sftp将文件上传到服务器主机

Question

我目前遇到这个错误:

Unhandled Exception: System.Net.SocketsExceptions: No such host is known...

不太清楚那是什么意思，但这就是我所做的。

public FileUploader(/*string host, string port, string username, string password,*/ string fileLocation)
    {
      string temp;
      Console.Write("Server URL:");
      this.host = Console.ReadLine();
      Console.Write("Server Port:");
      temp = Console.ReadLine();
      this.port = int.Parse(temp);
      Console.Write("Username:");
      this.username = Console.ReadLine();
      Console.Write("Password:");
      this.password = ReadPassword();
      Console.Write("Folder Location:");
      this.fileLocation = Console.ReadLine();
    }

    public void UploadFile(string pathToFile)
    {
      var client = new SftpClient(host, port, username, password);
      client.Connect();
      var fileStream = new FileStream(pathToFile, FileMode.Open);
      client.BufferSize = 4 * 1024;
      client.UploadFile(fileStream,fileLocation, null);
      client.Disconnect();
      client.Dispose();
    }

当我在主机名 中包含“ftp://”和“sftp://”时，我遇到了类似的问题。在我的搜索中，谷歌将我带到了这里。这是因为我从 FtpWebRequest 切换到 SSH.Net，我的主机值以前是一个 url。

我将以下代码作为工作主机名值的示例。其他人也可以改用 IP 地址。

const string sFtpHost = "someprefix.somedomain.com";
const int sFtpPort = 22;
const string userName = "SomeUser";
const string password = "SomePassword";

// ...

string localFileName = SomeFileName;
string remoteFileName = @"/SomeSubFolder/" + System.IO.Path.GetFileName(localFileName);

using (var sftp = new SftpClient(sFtpHost, sFtpPort, userName, password))
{
    sftp.Connect();

    using (var file = File.OpenRead(localFileName))
    {
        sftp.UploadFile(input: file, path: remoteFileName, canOverride: true);
    }

    sftp.Disconnect();
}
