使用 WinSCP 和 PowerShell 在文件上传之间暂停

Question

我有以下 PowerShell 脚本，我非常感谢您对此的任何帮助。

该脚本从网络驱动器抓取文件名以COKA_*"开头的文件，并在何时上传到 SFTP 站点。

问题：目标站点不喜欢批量接收所有文件，而是一次接收一个。 每次文件传输之间有 60 秒的延迟。

在哪里可以在脚本或迭代中添加此延迟以一次只推送一个文件，延迟 60 秒？ 我真的很感激你的帮助。

param (

    $localPath = "U:\####\COKA_*", # Source, one or more files generated at on a request
    $remotePath = "/from_/feast/Outbound/", #Destination file location
    $backupPath = "U:\####\Archive", # archive file destination
)

try
{
    # Load WinSCP .NET assembly
    Add-Type -Path "E:\######\WinSCP\WinSCPnet.dll"

    # Set up session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "123.456.78.901"
        UserName = "iamencrypted"
        SshHostKeyFingerprint = "ssh-rsa 2048 DYPA3BjRCbKLosI5W9iamdefinatlydencrypted"
        SshPrivateKeyPath = "\\#####\###\###\##\FTP\######\#####\########.ppk"
    }

    $sessionOptions.AddRawSettings("AgentFwd", "1")

    $session = New-Object WinSCP.Session

    try
    {
        # Connect
        $session.Open($sessionOptions)

        # Upload files, collect results
        $transferResult = $session.PutFiles($localPath, $remotePath)

        # Iterate over every transfer
        foreach ($transfer in $transferResult.Transfers)
        {

            # Success or error?
            if ($transfer.Error -eq $Null)
            {
                Write-Host "Upload of $($transfer.FileName) succeeded, moving to Archive"
                # Upload succeeded, move source file to Archive
                Move-Item -force $transfer.FileName $backupPath
            }
            else
            {
                Write-Host "Upload of $($transfer.FileName) failed: $($transfer.Error.Message)"
            }
        }
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}

那么你不能使用带有文件掩码的Session.PutFiles 。

您必须找到要自己上传的文件，然后为每个文件分别调用Session.PutFiles并在 ( Start-Sleep ) 之间暂停。

为此使用Get-ChildItem 。

$files = Get-ChildItem $localPath

foreach ($file in $files)
{
    $localFilePath = $file.FullName
    $transferResult = $session.PutFiles($localFilePath, $remotePath)

    if ($transferResult.IsSuccess)
    {
        Write-Host "Upload of $localFilePath succeeded, moving to Archive"
        # Upload succeeded, move source file to Archive
        Move-Item -Force $localFilePath $backupPath
    }
    else
    {
        $err = $transferResult.Failures[0].Message
        Write-Host "Upload of $localFilePath failed: $err"
    }

    Start-Sleep -Seconds 60
}
