FTP密码中的特殊字符

本文关键字：特殊字符 密码 FTP | 更新日期: 2023-09-27 18:16:33

我正在尝试登录ftp服务器。在c#中使用以下代码:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp-server");
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
// This example assumes the FTP site uses anonymous logon.
//request.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequired;
request.Credentials = new NetworkCredential("userName", "password!#£");
FtpWebResponse response = (FtpWebResponse)request.GetResponse();

当密码中包含特殊字符时，登录失败。(如"!'或'£')?我得到以下异常:

Unhandled Exception: System.Net.WebException: The remote server returned an error: (530) Not logged in.
  at System.Net.FtpWebRequest.SyncRequestCallback(Object obj)
  at System.Net.FtpWebRequest.RequestCallback(Object obj)
  at System.Net.CommandStream.Dispose(Boolean disposing)
  at System.IO.Stream.Close()
  at System.IO.Stream.Dispose()
  at System.Net.ConnectionPool.Destroy(PooledStream pooledStream)
  at System.Net.ConnectionPool.PutConnection(PooledStream pooledStream, Object owningObject, Int32 creationTimeout, Bo
ean canReuse)
  at System.Net.FtpWebRequest.FinishRequestStage(RequestStage stage)
  at System.Net.FtpWebRequest.GetResponse()
  at FtpClientTest.Program.FtpWebRequest()

当密码不包含任何特殊字符时，我没有得到任何异常。

这是什么FTP服务器?您可以使用其他程序登录吗?如果是，请使用wireshark比较导线上的内容。

可能是ANSI编码，试试

var secureString = new SecureString();
foreach (var b in Encoding.Default.GetBytes("password!#£"))
    secureString.AppendChar((char)b);
request.Credentials = new NetworkCredential("userName", secureString);
