VBScript FTP Login with Username and Password

问题:

I am trying to update a VBScript (very little experience with this, I do a lot of VB.NET), that reads an FTP directory and moves certain files to a new local directory on a daily basis. I have old code that works on an FTP site that uses anonymous logins, but I now need it to access an FTP site that requires username and password.

Here is my current code -

Sub MoveNSPurolatorFile()

Dim NSPurolatorFTPSite, NSPurolatorMoveFilePath, NSPurolatorFTPFolder, NSPurolatorFTPFileName

Dim folder, files
Dim fso

set fso = CreateObject("Scripting.FileSystemObject")

NSPurolatorFTPSite="\\xxx.xxx.x.xx\"
NSPurolatorMoveFilePath = "F:\TestDirectory"
NSPurolatorFTPFolder = "TestFolder"

NSPurolatorFTPFileName =  "MAN0201.CSV"

If InStr(NSPurolatorFTPFileName, "_processed") = 0 and InStr(NSPurolatorFTPFileName, ".CSV") > 0 Then

    If fso.FolderExists(NSPurolatorFTPSite & NSPurolatorFTPFolder) Then

        If fso.FileExists(NSPurolatorFTPSite & NSPurolatorFTPFolder & NSPurolatorFTPFileName) Then

            objfile.writeline "NS Purolator File Found: " & NSPurolatorFTPSite & NSPurolatorFTPFolder & NSPurolatorFTPFileName
            fso.copyFile NSPurolatorFTPSite & NSPurolatorFTPFolder & NSPurolatorFTPFileName, NSPurolatorMoveFilePath & "\"  

        Else
            objfile.writeline "File does not exist: " & NSPurolatorFTPSite & NSPurolatorFTPFolder & NSPurolatorFTPFileName 
        End If 

    End If

End If

Next

End Sub

It says the folder does not exist, but I know it does and when I run this code against an ftp site that does not require username and password it works fine. I guess my question is - How do I pass in the username and password using VBScript to the ftp site before trying to access folders, etc?

Thanks.

This really is an incredibly bad way to do this. You can't just treat folders on a remote FTP site as local folders.

You really should be using InetCtrls.Inet.1

Here's an example I lifted from somewhere else that does not do what you want, but contains all the parts you need - you need to pick it apart to suit your needs.

'Option Explicit
'const progname="FTP upload script by Richard Finegold"
'const url = "ftp://ftp.myftpsite.com"
'const rdir = "mydir"
'const user = "anonymous"
'const pass = "[e-mail]"

'This is an example of ftp'ing without calling the external "FTP" command
'It uses InetCtrls.Inet.1 instead
'Included is a "hint" for simple downloading

'Insist on arguments
dim objArgs
Set objArgs = Wscript.Arguments
If 0=objArgs.Count Then
   MsgBox "No files selected for operation!", vbOkOnly + vbCritical, progname
   WScript.Quit
End If


'Force console mode - csforce.vbs (with some reorganization for efficiency)
dim i
if right(ucase(wscript.FullName),11)="WSCRIPT.EXE" then
  dim args, y
  For i = 0 to objArgs.Count - 1
    args = args + " " + objArgs(i)
  Next
  Set y = WScript.CreateObject("WScript.Shell")
  y.Run "cscript.exe " & wscript.ScriptFullName + " " + args, 1
  wscript.quit
end if


'Do actual work
dim fso, ftpo
set fso = WScript.CreateObject("Scripting.FileSystemObject")
set ftpo = WScript.CreateObject("InetCtls.Inet.1")     'Msinet.ocx
ftpo.URL = url
ftpo.UserName = user
ftpo.Password = pass
WScript.Echo "Connecting..."
ftpo.Execute , "CD " & rdir
do
'     WScript.Echo "."
     WScript.Sleep 100     'This can take a while loop while ftpo.StillExecuting


for i = 0 to objArgs.Count - 1
     dim sLFile
     sLFile = objArgs(i)

     if (fso.FileExists(sLFile)) then
          WScript.Echo "Uploading " & sLFile & " as " & FSO.GetFileName(sLFile) & " "
          ftpo.Execute , "Put " & sLFile & " " & FSO.GetFileName(sLFile)
          'ftpo.Execute , "Get " & sRemoteFile & " C:\" & sLFile
          do
          'WScript.Echo "."
               WScript.Sleep 100     'This can take a while
          loop while ftpo.StillExecuting
     else
          MsgBox Chr(34) & sLFile & Chr(34) & " does not exist!", _
           vbOkOnly, progname
     end if
next
WScript.Echo "Closing"
ftpo.Execute , "Close"
WScript.Echo "Done!"

Here's a pretty nice way to do it - I'm sure this could be improved upon, but I just got it going.. :-)

Dim fso, folder1, folder2, folder2a
Set fso = CreateObject("Scripting.FileSystemObject") 
Set folder2a = fso.GetFolder("C:\temp")

ftpFolderString = "ftp://username:[e-mail]/folderpath" 

targetFoldder = "C:\temp"
fileSearchStr = "searchstring"

Dim SH, txtFolderToOpen, thing
Set SH = CreateObject("Shell.Application") 

'SH.Open txtFolderToOpen 
Set folder1 = SH.NameSpace(ftpFolderString)
Set folder2 = SH.NameSpace(targetFoldder)
For Each item In folder1.items

    If InStr(LCase(item.Name),fileSearchStr) > 0 Then
        Debug.WriteLine item.Name
        folder2.CopyHere item,4
        WScript.Sleep(200)
        For Each item2 In folder2a.Files
            If item2.Name = item.Name Then
                While item2.Size < item.Size 
                    WScript.Sleep(200)
                Wend
            End If
        Next
        WScript.Sleep(200)
    End If

Next
Set SH = Nothing 
Debug.WriteLine "Done"

How is the script being run? Manually, automatically? By a service?

Mapped-letter drives are not always available when running as a service.

Experiment with the script to ensure that it even able to see the F:\ drive, and then see what else is visible.

回答4:

Is the FTP site accessed by a UNC path (looks like it is)? If it is just a standard FTP address then you can incorporate the username / password in the URL e.g. ftp://user:[e-mail]. If it is a UNC path that you are trying to access using different credentials then the easiest way would probably be to map a drive, do the work and then unmap the drive. 2 different approaches can be found here
