Question

我有一个脚本只需从给定的ftp服务器（备份工具）下载所有文件。

一切正常，但需要几个小时才能完成，所以我决定根据WinSCP documentation添加一些进度信息：

function FileTransferProgress {
    param($e)
    if(($script:lastFileName -ne $Null) -and ($script:lastFileName -ne $e.FileName)) {
        Write-Host
    }
    Write-Host -NoNewline ("`r`t{0} ({1:P0})" -f $e.FileName, $e.FileProgress)
    $script:lastFileName = $e.FileName
}
$script:lastFileName = $Null


$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::ftp
    HostName = $ftpHostName
    UserName = $ftpUserName
    Password = $ftpPassword
}
...
$session.add_FileTransferProgress( { FileTransferProgress($_) } )
...
//start FTP session, open connection etc.
...

$transferOptions = New-Object WinSCP.TransferOptions
$transferOptions.TransferMode = [WinSCP.TransferMode]::Binary   
$session.GetFiles($hostFolderPath, ($targetFolderPath + "\*"), $False, $transferOptions).Check()

//message about finished trasnfer
...

如果没有我的$session.add_FileTransferProgress( { FileTransferProgress($_) } )，一切正常，但需要很长时间才能看到完成消息。使用add_FileTransferProgress我无法传输任何文件，而是在几分钟后我总是最终得到：

错误：超时等待WinSCP响应

我不更改了工作代码中的任何其他内容（仅添加了FileTransferProgress和functin FileTransferProgress）。我想这个程序会在WinSCP通常会显示＆＃34;计算目录＆＃34;时崩溃。（在传输文件之前）。

当我评论$session.add_FileTransferProgress( { FileTransferProgress($_) } )时，一切正常。此外，使用$session.PutFiles上传少量文件同时使用注释和未注释的行（它会输出上传的％进度）。

请求Martin Prikryl：

我从开始运行此脚本 - ＆gt; Powershell（作为管理员），然后cd到它的位置和./script.ps1（两种情况完全相同）。

我已经放置了：

$session.SessionLogPath = "I:\Sites\Temp\TransferLog.xml"
$session.DebugLogPath = "I:\Sites\Temp\TransferDebugLog.xml"

之前$session.open(...)但只出现了调试日志（TransferDebugLog.xml）（我发布了部分内容，因为它的文件很大）：
