使用VBScript从FTP下载多个文件

问题描述

我完全不是VB Scripting的专家，但是因为这是我目前的一个项目的需求，所以我正在尝试编写一个VBScript来从指定的FTP文件夹中获取所有文件。

我设法得到一个指定的文件，但我似乎无法获取文件夹中的所有文件。这里是我试图使用的脚本：

  Dim objOutStream 
 Const OpenAsDefault = -2 
 Const FailIfNotExist = 0 
 Const ForReading = 1 
 Const ForWriting = 2 
 Set objFSO = CreateObject（Scripting.FileSystemObject）
 Set objOutStream = objFSO.OpenTextFile（C：\ temp \temp\empty.txt，ForWriting，True，TristateFalse）
使用objOutStream 
 .WriteLineUSER myuser'USERNAME 
 .WriteLinemypass'Password 
 .WriteLinebinary
 .WriteLineprompt n
 .WriteLinelcd / foldertocopyfrom'文件夹我正在更改为
 .WriteLinemget *'获取当前日期的所有文件in 
 .WriteLinebye
 .Close 
 End With 
 
 Set oFTPScriptShell = CreateObject（WScript.Shell）
 oFTPScriptShell.Run ％comspec％/ c FTP -n -s：& C：\temp\temp\empty.txt& & ftp.location.com，0，True 
  

它不会给我一个错误或任何东西，它基本上什么都不做（是的，我确定/ foldertocopy中的文件来自： - ））

任何想法？

谢谢！

解决方案

我试过了你的解决方案，但必须做一些小的修复，使其工作：
$ b

• 添加选项显式（更好地检测未定义的变量）
  li>
  
• 删除TristateFalse参数


• 删除提示符因为交互模式已关闭，因此切换
>

• 更改 bye 至退出


• 已添加-i参数添加到FTP命令中
  
• 另外，我在命令行上测试了您的FTP命令，然后在您的脚本中使用它

以下是修改过的脚本

pre $ $ $ c $ Option Option Explicit

Const ForWriting = 2

Dim objOutStream，objjFSO，objShell
Set objFSO = CreateObject（Scripting.FileSystemObject）
Set objOutStream = objFSO.OpenTextFile（C：\temp\temp\ empty.txt，ForWriting，True）
使用objOutStrea m
.WriteLineUSER myuser'USERNAME
.WriteLinemypass'Password
.WriteLinebinary
.WriteLinelcd / foldertocopyfrom'文件夹我正在更改转换为
.WriteLinemget *'获取所有当前日期的文件
.WriteLinequit
.Close
End With

Set objShell = CreateObject（WScript.Shell）
objShell.Run％comspec％/ c FTP -n -i -s：& C：\temp\temp\empty.txt& & ftp.location.com，0，True

I'm not at all an expert at VB Scripting, but since it's a requirement at one of my projects for the moment, I am trying to write a VBScript that will GET all files from a specified FTP Folder.

I manage to get a single specified file, but I can't seem to get all files in a folder. Here's the script I'm trying to use:

    Dim objOutStream
  Const OpenAsDefault = -2
  Const FailIfNotExist = 0
  Const ForReading = 1
  Const ForWriting = 2
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objOutStream = objFSO.OpenTextFile("C:\temp\temp\empty.txt", ForWriting, True, TristateFalse)
With objOutStream
    .WriteLine "USER myuser"   ' USERNAME
    .WriteLine "mypass"     ' Password
    .WriteLine "binary"
    .WriteLine "prompt n"
    .WriteLine "lcd /foldertocopyfrom" ' FOLDER I'm changing into
    .WriteLine "mget *"    ' Get all files with today's date in it
    .WriteLine "bye"
    .Close
End With

Set oFTPScriptShell = CreateObject("WScript.Shell")
oFTPScriptShell.Run "%comspec% /c FTP -n -s:" & "C:\temp\temp\empty.txt" & " " & "ftp.location.com", 0, True

It doesn't give me an error or anything, it basically does nothing (and yes, I'm sure there are files in the /foldertocopy from :-))

Any ideas? Something obvious I am missing?

Thanks!

解决方案

I tried your solution but had to make a couple small fixes to make it work:

• Added Option Explicit (for better detection of undefined variables)
• Removed the TristateFalse parameter
• Removed prompt since toggle since interactive mode is already off
• Changed bye to quit
• Added -i parameter to the FTP command
• Plus I tested your FTP command on the command line before using it in your script

Here's the modified script

Option Explicit

Const ForWriting = 2

Dim objOutStream, objjFSO, objShell
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objOutStream = objFSO.OpenTextFile("C:\temp\temp\empty.txt", ForWriting, True)
With objOutStream
    .WriteLine "USER myuser"   ' USERNAME
    .WriteLine "mypass"     ' Password
    .WriteLine "binary"
    .WriteLine "lcd /foldertocopyfrom" ' FOLDER I'm changing into
    .WriteLine "mget *"    ' Get all files with today's date in it
    .WriteLine "quit"
    .Close
End With

Set objShell = CreateObject("WScript.Shell")
objShell.Run "%comspec% /c FTP -n -i -s:" & "C:\temp\temp\empty.txt" & " " & "ftp.location.com", 0, True
