用于下载、重命名和移动文件的 WinSCP 脚本

到目前为止，我一直在使用 WS_FTP，但想切换到 WinSCP。 我正在尝试将此 WS_FTP 脚本转换为 WinSCP：

"C:\Program Files (x86)\Ipswitch\WS_FTP 12\wsftppro.exe"
-s "sftp://USERNAME:[email protected]/USERNAME/logs/*.sqb"
-d "local:C:\PccDataRelay\LogDownloads\"
-rename tx_[yyyy]-[mm]-[dd]_[hh]-[tt]-[ss]_[OnlyName].[OnlyExt]
-move "/USERNAME/logs/transferred/"

我已经能够部分转换它：

cd C:\PccDataRelay\TestDownloads

"C:\Program Files (x86)\WinSCP\winscp.com" /ini=nul /log=C:\PccDataRelay\AuditLogs\incremental_download.log /command ^
    "open sftp://USERNAME:[email protected]/USERNAME/logs/ -hostkey=""ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx""" ^
    "get /USERNAME/logs/*.sqb" ^
    "exit"

但仅此而已下载文件。我怎样才能得到它rename and move原始文件，同时将它们保留在 FTP 站点上？

WinSCP没有类似的功能-rename and -move开关。因此，在简单的脚本中实现此任务并不容易，以便其以事务方式运行（仅重命名和移动已成功下载的文件）

但你可以使用WinSCP .NET 程序集 from a PowerShell 脚本.

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "ftpus.pointclickcare.com"
    UserName = "USERNAME"
    Password = "PASSWORD"
    SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
}

# Connect
Write-Host "Connecting..."
$session = New-Object WinSCP.Session
$session.SessionLogPath = "C:\PccDataRelay\AuditLogs\incremental_download.log"
$session.Open($sessionOptions)

# Download files
$transferResult =
    $session.GetFilesToDirectory(
        "/USERNAME/logs", "C:\PccDataRelay\LogDownloads", "*.sqb")

# Process source files
foreach ($transfer in $transferResult.Transfers)
{
    $oldName = $transfer.FileName
    # Success or error?
    if ($transfer.Error -eq $Null)
    {
        $newName =
            "/USERNAME/logs/transferred/tx_" +
            (Get-Date -Format "yyyy-MM-dd-hh-mm-ss") + "_" +
            [IO.Path]::GetFileName($oldName)
        Write-Host (
            "Download of $oldName succeeded, moving to backup $newName")
        $session.MoveFile($oldName, $newName)
    }
    else
    {
        Write-Host (
            "Download of $oldName failed: $($transfer.Error.Message)")
    }
}

• 上传成功后将本地文件移至其他位置;
• 在批处理文件中格式化时间戳.
