windows - Powershell-扩展存档和重命名文件，因为其中包含无效字符

Question

我无法使用Powershell解压缩存档。

假设我已经下载了file.zipfile.zip的文件名中带有“冒号”的文件。 (即foo:bar.p12)

使用7zip手动解压缩这些文件会自动用下划线(:)替换冒号(_)。工作正常!

在powershell中使用expand-archive会引发以下错误:

> New-Object : Exception calling ".ctor" with "1" argument(s): "The
> given path's format is not supported." At
> C:\Windows\system32\WindowsPowerShell\v1.0\Modules\Microsoft.PowerShell.Archive\Microsoft.PowerShell.Archive.psm1:1004
> char:52

>     + CategoryInfo          : InvalidOperation: (:) [New-Object], MethodInvocationException
>     + FullyQualifiedErrorId : ConstructorInvokedThrowException,Microsoft.PowerShell.Commands.NewObjectCommand

这是我的代码:

$zip_location = "C:\path\to\zipfiles"
$zipfiles = Get-ChildItem $zip_location -Filter *.zip

foreach ($zip in $zipfiles) {
    Expand-Archive -Path $zip_location\$zip -DestinationPath $zip_location -Force
}

有没有办法使用Powershell提取这些文件？谢谢你。

使用 ZipFile type手动提取文件:

# Import the containing assembly
Add-Type -AssemblyName System.IO.Compression.FileSystem

try{
  # Open the zip file with ZipFile.OpenRead()
  $zipFileItem = Get-Item .\Path\To\File.zip
  $zipFile = [System.IO.Compression.ZipFile]::OpenRead($zipFileItem.FullName)

  foreach($entry in $zipFile.Entries){
    # Remove the `:` from any file name
    $targetFileName = $entry.Fullname -replace ':','_'

    # Create new file on disk, open writable stream
    $targetFileStream = $(
        New-Item -Path $targetFileName -ItemType File -Force
    ).OpenWrite()

    # Open stream to compressed file, copy to new file stream
    $entryStream = $entry.Open()
    $entryStream.BaseStream.CopyTo($targetFileStream)

    # Clean up
    $targetFileStream,$entryStream |ForEach-Object Dispose
  }
}
finally{
  # clean up
  if($zipFile){ $zipFile.Dispose() }
}
