如何编写FTP上传和下载脚本 [英] How to script FTP upload and download
问题描述
我正在尝试制作批处理文件以将文件上传到 FTP 服务器.如果我手动输入它工作正常，但是当我运行批处理文件时，它在连接后停止......它说:
I'm attempting to make a batch file to upload a file to an FTP server. If I type it in manually it works fine, but when I run the batch file it halts after it's connected... It says:
connected to domain.com.
220 microsoft ftp server
User(domain.com:(none)):
然后就没有别的了.这是怎么回事?
And then nothing else. What is going on here?
下面是我的批处理文件:
Below is my batch file:
ftp www.domainhere.com
user useridhere
passwordhere
put test.txt
bye
pause
推荐答案
想要按照原发帖者想象的方式编写 FTP 会话脚本是一个合理的想法，而这正是 Expect 会有所帮助.Windows 上的批处理文件无法执行此操作.
It's a reasonable idea to want to script an FTP session the way the original poster imagined, and that is the kind of thing Expect would help with. Batch files on Windows cannot do this.
但与执行 cURL 或 Expect 相比，您可能会发现使用 PowerShell 编写 FTP 交互脚本更容易.这是一个不同的模型，因为您没有直接编写要发送到 FTP 服务器的文本的脚本.相反，您将使用 PowerShell 来操作为您生成 FTP 对话的对象.
But rather than doing cURL or Expect, you may find it easier to script the FTP interaction with PowerShell. It's a different model, in that you are not directly scripting the text to send to the FTP server. Instead you will use PowerShell to manipulate objects that generate the FTP dialogue for you.
上传:
$File = "D:Devsomefilename.zip"
$ftp = "ftp://username:password@example.com/pub/incoming/somefilename.zip"
"ftp url: $ftp"
$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)
"Uploading $File..."
$webclient.UploadFile($uri, $File)
下载:
$File = "c:storesomefilename.zip"
$ftp = "ftp://username:password@example.com/pub/outbound/somefilename.zip"
"ftp url: $ftp"
$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)
"Downloading $File..."
$webclient.DownloadFile($uri, $File)
您需要 PowerShell 来执行此操作.如果您不知道，PowerShell 是一个类似于 cmd.exe 的外壳程序，它运行您的 .bat 文件.但是 PowerShell 运行 .ps1 文件，而且功能要强大得多.PowerShell 是 Windows 的免费附加组件，将内置到 Windows 的未来版本中.从这里获取.
You need PowerShell to do this. If you are not aware, PowerShell is a shell like cmd.exe which runs your .bat files. But PowerShell runs .ps1 files, and is quite a bit more powerful. PowerShell is a free add-on to Windows and will be built-in to future versions of Windows. Get it here.
