连接FTP服务器的凭据 [英] Connecting ftp server with credentials
问题描述
我正在写使用带有凭据的FTP服务器程序。我试图从服务器检索目录列表中,但是当我站上罚球线:
I'm writing a program that uses an ftp server with credentials. I'm trying to retrieve the directory list from the server but when I get to the line:
string line = reader.ReadLine();
这是我得到的字符串只包含:无法打开\主持人:/ lib1\\ 。\\
the string that I get contains only : "Can't open \"host:/lib1\"."
如果我试图让另一条线,下抛出异常:远程服务器返回错误:(550)文件不可用(例如,文件不发现,没有访问权限)。
If I try to get another line, the next exception is thrown: The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
我知道肯定(使用其他FTP应用程序)存在的FTP服务器上LIB1目录和我的凭据(用户名和密码)是。正确的
I know for sure (using another ftp application) that 'lib1' directory exists on the ftp server and my credentials (username and password) are correct.
下面是我的代码:
public class FTPClient
{
public string UserName { get; set; }
public string Password { get; set; }
public string IpAddress { get; set; }
public int Port { get; set; }
public FTPClient(string _userName, string _password, string _address, int _port)
{
UserName = _userName;
Password = _password;
IpAddress = _address;
Port = _port;
}
public void GetDirectoriesList(string _path)
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(new Uri("ftp://" +
IpAddress + _path));
request.UseBinary = true;
request.Method = WebRequestMethods.Ftp.ListDirectory;
request.Credentials = new NetworkCredential(UserName, Password);
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
string line = reader.ReadLine();
while (line!=null)
{
... //do something with line
line = reader.ReadLine();
}
...
reader.Close();
response.Close();
}
和我使用它,如下所示:
And I use it as follows:
FTPClient ftpClient = new FTPClient("user1", "pass1", "192.168.2.110", 21);
string dirList = ftpClient.GetDirectoriesList("/lib1");
任何人都可以发现这个问题?
Can anyone spot the problem?
推荐答案
我的解决办法:
public string[] GetDirectory()
{
StringBuilder result = new StringBuilder();
FtpWebRequest requestDir = (FtpWebRequest)WebRequest.Create("ftp://urserverip/");
requestDir.Method = WebRequestMethods.Ftp.ListDirectory;
requestDir.Credentials = new NetworkCredential("username", "password");
FtpWebResponse responseDir = (FtpWebResponse)requestDir.GetResponse();
StreamReader readerDir = new StreamReader(responseDir.GetResponseStream());
string line = readerDir.ReadLine();
while (line != null)
{
result.Append(line);
result.Append("\n");
line = readerDir.ReadLine();
}
result.Remove(result.ToString().LastIndexOf('\n'), 1);
responseDir.Close();
return result.ToString().Split('\n');
}
