Filewatcher 在检测到事件 (.zip) 时进行解压缩和处理
Filewatcher to unzip and process when event (.zip) is detected
我想创建一个文件观察器并使用 PowerShell 执行以下流程:
在文件夹 A 中寻找文件 (.zip) → 将文件作为 (.zip) 移动到文件夹 B → 将移动的文件解压缩到文件夹 C 中(同名)→ 并触发批处理文件 → 对更多传入文件执行相同操作.zip 文件。
我在 Whosebug 中检查了 related question,但我需要更多帮助。
我的 PowerShell 脚本如下(我使用的是 PowerShell ISE):
while ($true) {
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "D:\LocalData\Desktop\folderA"
$watcher.Filter = "*.zip*"
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true
$tempfolder = "D:\LocalData\Desktop\folderA\folderB"
$outpath = "D:\LocalData\Desktop\folderA\folderB\folderC"
#Function to Unzip the moved item
Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip {
Param([string]$path, [string]$outpath)
[System.IO.Compression.ZipFile]::ExtractToDirectory($path, $outpath)
}
$action = {
$path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
$name = $Event.SourceEventArgs.Name
Move-Item $path $tempfolder
Unzip $path $outpath -Force # this line is not being read, it goes to the function block, and slips down to the action block
$logline = "$(Get-Date), $changeType, $path" # no log is generated
Add-Content -Path "d:\LocalData\folderA\Watcherlog.log" $logline
Start-Process -Path "d:\LocalData\process.bat"
}
Register-ObjectEvent $watcher "Created" -Action $action
Start-Sleep 2
}
Unregister-Event -SourceIdentifier FileCreated
这是你的错误:
$action = {
...
Move-Item $path $tempfolder
Unzip $path $outpath -Force
...
}
您将文件移动到其他位置,但在文件已移动后尝试从原始位置解压缩。
将您的脚本块更改为类似这样的内容,它应该会按预期工作:
$action = {
$path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
Unzip $path $outpath -Force
Remove-Item $path
"$(Get-Date), $changeType, $path" | Add-Content -Path "d:\LocalData\folderA\Watcherlog.log"
Start-Process -FilePath "d:\LocalData\process.bat" -Wait
}
