如何编写FTP上传和下载脚本？

Question

我正在尝试制作批处理文件以将文件上传到ftp服务器.如果我手动输入它可以正常工作,但是当我运行批处理文件时,它会在连接后暂停...它说

connected to domain.com.

220 microsoft ftp server

User(domain.com:(none)):

没什么别的.到底发生了什么事？

以下是我的批处理文件:

ftp www.domainhere.com 

user useridhere

passwordhere

put test.txt

bye

pause

Answer 1

想要以原始海报想象的方式编写FTP会话脚本是一个合理的想法,这就是Expect可以帮助的东西.Windows上的批处理文件无法执行此操作.

但是,您可能会发现使用Powershell编写FTP交互脚本更容易,而不是执行cURL或Expect.它是一个不同的模型,因为您不直接编写要发送到FTP服务器的文本脚本.相反,您将使用Powershell来操纵为您生成FTP对话的对象.

上传:

$File = "D:\Dev\somefilename.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:\store\somefilename.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)

你需要Powershell才能做到这一点.如果您不知道,Powershell是一个类似cmd.exe的shell,它运行您的.bat文件.但是Powershell运行.ps1文件,并且功能更强大.Powershell是Windows的免费附加组件,将内置于未来版本的Windows中.来吧.

使用命令创建命令文件

即:commands.txt

open www.domainhere.com
user useridhere 
passwordhere
put test.txt
bye

然后从命令行运行FTP客户端:ftp -s:commands.txt

注意:这适用于Windows FTP客户端.

编辑:在密码之前的用户名之后应该有换行符.

Answer 3

批处理文件不起作用.它们不只是"键入"所有东西 - 它们运行系统命令,在这种情况下ftp,等待它们返回,然后运行下一个命令......所以在这种情况下,解释器只是等待ftp退出.

如果必须使用该ftp命令,则准备一个脚本文件(例如,commands.txt然后运行ftp -s:commands.txt.

但是使用cURL或PHP/Perl/Python /任何脚本可能是个更好的主意.

我用PowerShell完成了这个:

function DownloadFromFtp($destination, $ftp_uri, $user, $pass){
    $dirs = GetDirecoryTree $ftp_uri $user $pass

    foreach($dir in $dirs){
       $path = [io.path]::Combine($destination,$dir)

       if ((Test-Path $path) -eq $false) {
          "Creating $path ..."
          New-Item -Path $path -ItemType Directory | Out-Null
       }else{
          "Exists $path ..."
       }
    }

    $files = GetFilesTree $ftp_uri $user $pass

    foreach($file in $files){
        $source = [io.path]::Combine($ftp_uri,$file)
        $dest = [io.path]::Combine($destination,$file)

        "Downloading $source ..."
        Get-FTPFile $source $dest $user $pass
    }
}

function UploadToFtp($artifacts, $ftp_uri, $user, $pass){
    $webclient = New-Object System.Net.WebClient 
    $webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)  

    foreach($item in Get-ChildItem -recurse $artifacts){ 

        $relpath = [system.io.path]::GetFullPath($item.FullName).SubString([system.io.path]::GetFullPath($artifacts).Length + 1)

        if ($item.Attributes -eq "Directory"){

            try{
                Write-Host Creating $item.Name

                $makeDirectory = [System.Net.WebRequest]::Create($ftp_uri+$relpath);
                $makeDirectory.Credentials = New-Object System.Net.NetworkCredential($user,$pass) 
                $makeDirectory.Method = [System.Net.WebRequestMethods+FTP]::MakeDirectory;
                $makeDirectory.GetResponse();

            }catch [Net.WebException] {
                Write-Host $item.Name probably exists ...
            }

            continue;
        }

        "Uploading $item..."
        $uri = New-Object System.Uri($ftp_uri+$relpath) 
        $webclient.UploadFile($uri, $item.FullName)
    }
}

 function Get-FTPFile ($Source,$Target,$UserName,$Password) 
 { 
     $ftprequest = [System.Net.FtpWebRequest]::create($Source) 
     $ftprequest.Credentials = New-Object System.Net.NetworkCredential($username,$password) 
     $ftprequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile 
     $ftprequest.UseBinary = $true 
     $ftprequest.KeepAlive = $false 

     $ftpresponse = $ftprequest.GetResponse() 
     $responsestream = $ftpresponse.GetResponseStream() 

     $targetfile = New-Object IO.FileStream ($Target,[IO.FileMode]::Create)
