我正在创建一个用于从sftp服务器下载文件的窗口服务。为此我使用Renci.SshNet
,Renci.SshNet.Common
和Renci.SshNet.Sftp
。使用PPK密钥和密码进行多因素身份验证(非密码)
我有这样的代码:
String Host = "HostName";
int Port = 22;
String RemoteFileDirectory =
Convert.ToString(ConfigurationManager.AppSettings["SourcePath"]);
String Username = "UserName";
String Password = "*******";
var KeybasedMethod = new KeyboardInteractiveAuthenticationMethod(Username);
KeybasedMethod.AuthenticationPrompt +=
(sender, e) => { e.Prompts.First().Response = password; };
AuthenticationMethod[] methods = new AuthenticationMethod[]
{
new PrivateKeyAuthenticationMethod(Username, new PrivateKeyFile(@"Z:\SFTP SETUP\CJ22")),
KeybasedMethod
};
ConnectionInfo connectionInfo = new ConnectionInfo(hostname, username, methods);
using (var sftp = new SftpClient(connectionInfo))
{
sftp.Connect();
// ...
}
异常就说明是。
找不到合适的认证方法来完成认证。
据我所知这个错误是说我的凭证是错误的连接,但它不是这样的。
我尝试了以下解决方案,但都没有工作。
- Download files from SFTP with SSH.NET library
- Unable to upload a file SFTP using SSH.NET in C# - Permission Denied
我无法弄清楚什么我缺少在我的代码。
下面是我在使用FileZilla从客户端计算机登录到服务器时获得的日志文件。

我试着从这里和其他来源多个解决方案一个接一个,但都没有工作。如果您有任何建议,那么这是非常值得欢迎的。
