我使用 Powershell、FileSytemWatcher 和 WinSCP 进行不稳定的文件传输

Question

我的 PowerShell 脚本将文件放入 ESB 时出现问题。通常它可以工作，但并非总是如此，尤其是对于大文件会出错。有没有人看到我的脚本中的错误或 tackle/resolve 我的问题的解决方法？

注：

无法继续支持，因为我没有更改权。
"WinSCP GUI" 我设法成功上传了大文件。（恢复支持关闭）
包含要上传的文件的目录会被监控以创建文件，然后将文件复制到单独的文件夹以供上传。上传成功后，文件被删除（从第二个文件夹）。
我是 PowerShell 的初学者，所以可能是错误的原因。英语也不是我的母语，所以请原谅我的任何错误。

脚本在 TaskScheduler 中启动：

    Powershell.exe -NoExit -File "script.ps1"

脚本如下：

    $folder = 'Original_Folder'
    $filter = '*.xml'                             
    $destination = 'CopyTo_Folder'
    $fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{
    IncludeSubdirectories = $false              
    NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'
    }
    $onCreated = Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
    $path = $Event.SourceEventArgs.FullPath
    $name = $Event.SourceEventArgs.Name
    $changeType = $Event.SourceEventArgs.ChangeType
    $timeStamp = $Event.TimeGenerated
    Write-Host "$timeStamp The file '$name' was $changeType and copied for SFTP to $destination"
    "$timeStamp The file '$name' was $changeType and copied for SFTP to $destination" | Set-Content 'Powershell_Script.log'
    Copy-Item $path -Destination $destination -Force -Verbose

    # Load WinSCP .NET assembly
    Add-Type -Path "C:\Program Files (x86)\WinSCP_5_11_3\WinSCPnet.dll"

    # Set up session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "ftp-server"
    UserName = "User account"
    Password = "User password"
    SshHostKeyFingerprint = "ssh-rsa bla bla"
    }

    $sessionOptions.AddRawSettings("FSProtocol", "2")

    $session = New-Object WinSCP.Session
    $Session.SessionLogPath="WinSCP.log"
    try
    {
        # Connect
        $session.Open($sessionOptions)

        # Upload files

            # Set up transfer options
            $transferOptions = New-Object WinSCP.TransferOptions -Property @{
            ResumeSupport = New-Object WinSCP.TransferResumeSupport -Property @{ State = [WinSCP.TransferResumeSupportState]::Off }
            }

            # Upload with transferoptions and delete original when succesfull    
            $transferResult=$session.PutFiles("CopyTo_Folder\*", "/Upload_Folder on ftp-server/", $True, $transferOptions)

            # Throw on any error
            $transferResult.Check()

            # Print results
            foreach ($transfer in $transferResult.Transfers)
            {
                Write-Host "Upload of $($transfer.FileName) succeeded"
                "$timeStamp The file $($transfer.FileName) was successfully uploaded" | Add-Content 'Powershell_Script.log'
            }

    }
    finally
    {
        $session.Dispose()
    }
    }

我似乎已经解决了这个问题。

在暂停之间获取复制操作时，它工作正常

所以：

    Start-Sleep -s 30
    Copy-Item $path -Destination $destination -Force -Verbose
    Start-Sleep -s 30

FileSystemWatcher 立即行动，正如预期的那样？因此，文件在未完全创建时被复制。在复制命令后，上传将立即开始，所以我也在那里暂停，以便复制操作可以在上传开始之前完成。

最好也监视这些操作，并在操作完成后让脚本恢复。虽然我不知道用 FSW 创建文件是否可行...
