Found By: DeveloperNet
Description of Problem:
The code below operates under windwos but not Linux file is created, but it
is empty.
I think that the bug is in 'Credentials' because I can download files on
server without authentication(Login/Password).
With my code I was able to download a file on the server
&quot;<A HREF="ftp://ftp-developpez.com/konflor/Latex/formation/FormationLatex.pdf&quot;">ftp://ftp-developpez.com/konflor/Latex/formation/FormationLatex.pdf&quot;</A>
anonymously. But on my local server when I want to download a file with a
loggin and a password, my stream &quot;ResponceStream&quot; is empty and there is no
error. My code works on windows and ftp server! My FTP server is not under
windows!
Sorry for my English I am french
Sub dl(ByVal remoteFile As String, ByVal localFile As String, ByVal
username As String, ByVal password As String)
'1. Create a request: must be in <A HREF="ftp://hostname">ftp://hostname</A> format,
' not just ftp.myhost.com
Dim URI As String = remoteFile
Dim ftp As System.Net.FtpWebRequest = CType(FtpWebRequest.Create(URI),
FtpWebRequest)
'3. Settings and action
ftp.KeepAlive = False
'we want a binary transfer, not textual data
ftp.UseBinary = True
'Define the action required (in this case, download a file)
ftp.Method = System.Net.WebRequestMethods.Ftp.DownloadFile
'2. Set credentials
if not (username = &quot;&quot; andalso password = &quot;&quot;) then
ftp.Credentials = New NetworkCredential( username, password)
end if
'4. If we were using a method that uploads data e.g. UploadFile
' we would open the ftp.GetRequestStream here an send the data
'5. Get the response to the Ftp request and the associated stream
Using response As System.Net.FtpWebResponse = CType(ftp.GetResponse,
System.Net.FtpWebResponse)
Using responseStream As IO.Stream = response.GetResponseStream
'loop to read &amp; write to file
Using fs As New IO.FileStream(localFile, IO.FileMode.Create)
Dim buffer(2047) As Byte
Dim read As Integer = 0
Do
read = responseStream.Read(buffer, 0, buffer.Length)
fs.Write(buffer, 0, read)
Loop Until read = 0 'see Note(1)
responseStream.Close()
fs.Flush()
fs.Close()
End Using
End Sub End Using
responseStream.Close()
End Using
response.Close()
End Using
End Sub
Steps to reproduce the problem:
1.
2.
Actual Results:
File with 0 bytes.
Expected Results:
How often does this happen?
Always
Additional Information:
Solution that I have currently is through a socket with whom I send commands!
