Powershell启动作业脚本块未执行

我有一些非常简单的代码,旨在将目录中的每个文件转换为HTML。我的问题是,虽然为每个文件成功创建了一个作业,但是脚本块永远不会运行。

$convert = {

Param(
    [parameter(ValueFromPipeline=$true)]
    $file
)

$content = Get-Content -Path $file.FullName
$outDir= New-Item -Type dir -Path $file.FullName + "\HTMLFiles"
$outFile = $outDir + $file.Name +  ".html"

foreach($line in $content) {
     #move the content into a variable and add some html tags
     $html = $html + '<tr>' + $line + '</tr>' +'<br>'
}
#convert the variable to .html and save the result as a file
ConvertTo-Html -Head $style -Body $html | Out-File -FilePath $outFile -Encoding "ASCII"
#empty the variable
$html = " "
}

Function main
{
Param(
   [parameter(Position=0, Mandatory=$true, ValueFromPipeLine=$true)]
   $target = $args[0]
)
#stores some html styling code
$path = $pwd.Path + "\style.txt"
$style = Get-Content -Path $path
#collect all files in the dirctory
$files = Get-ChildItem -Path $target -Recurse

foreach($file in $files) {
#for each file in the collection start a job which runs the given scriptblock (scriptblock is not working)
Start-Job -Name $file.name -ScriptBlock $convert -ArgumentList $file
}
#clean-up
Write-Host "Finished jobs"
Wait-Job *
Remove-Job -State Completed
}

main($args[0])

我对powershell很新,并且已经解决了解决这个问题的方法,但似乎无法解决这个问题。

答案 0 :(得分:-1)

  • 更改:我从脚本块和函数中删除了参数。
  • 原因:因为参数是由Start-Job传入的,也是通过语法function name (argument1, argument2) {}传递的。

我也从函数调用的括号中删除了,因为在Powershell中你可以调用以下函数: function "argument1" "argument2"


$convert = {    
    $content = Get-Content -Path $file.FullName
    $outDir= New-Item -Type dir -Path $file.FullName + "\HTMLFiles"
    $outFile = $outDir + $file.Name +  ".html"

    foreach($line in $content) {
        #move the content into a variable and add some html tags
        $html = $html + '<tr>' + $line + '</tr>' +'<br>'
    }
    #convert the variable to .html and save the result as a file
    ConvertTo-Html -Head $style -Body $html | Out-File -FilePath $outFile -Encoding "ASCII"
    #empty the variable
    $html = " "
}

Function main ($args)
{
    $target = $args
    #stores some html styling code
    $path = $pwd.Path + "\style.txt"
    $style = Get-Content -Path $path
    #collect all files in the dirctory
    $files = Get-ChildItem -Path $target -Recurse

    foreach($file in $files) {
        #for each file in the collection start a job which runs the given scriptblock (scriptblock is not working)
        Start-Job -Name $file.name -ScriptBlock $convert -ArgumentList $file
    }
    #clean-up
    Write-Output "Finished jobs"
    Wait-Job *
    Remove-Job -State Completed
}

main $args[0]
