我正在修改下面的代码。它应该创建一个 PoshRSJob 并foo
在那里的运行空间中再次运行该函数。
我希望能够将$list
参数转换为[array]
or [string[]]
,但是当我这样做时会引发错误。我考虑将我的数组展平为一个字符串,但如果我更改$list3
为在字符串中包含空格或逗号,它也会引发错误。我相信是这条线导致了这个问题,但我不知道为什么或怎么做才能绕过这个问题:
ScriptBlock = [scriptblock]::Create("`$_ | $($PSCmdlet.MyInvocation.MyCommand.Name) -Parallel:`$false -fn:$fn -sqlQuery:$SQLQuery -option:$option -List:$List")
代码:
function foo {
[CmdletBinding()]
param (
[Parameter(Mandatory=$true, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)]
[Alias("ComputerName")]
[PSObject] $InputObject,
[switch] $Parallel = $true,
[string] $fn,
[string] $sqlQuery = "none",
[string] $option = "none",
[int] $number,
[int] $Throttle = 100,
#Want this to be [array] or [string[]] :
[string] $List = "none"
)
begin {
$batch = [System.Guid]::NewGuid().Guid #run all jobs under same batch number
}
process {
if ($Global:debugging -eq $true){$host.ui.WriteDebugLine("fn:$fn | SQLQuery:$sqlQuery")}
if (!$Parallel) {
$server = $InputObject.name
switch($fn){
Manage{ return $list }
} #end switch
} else {#region Parallel run
$jobArguments = @{
Throttle = $Throttle
Batch = $batch
FunctionsToLoad = $PSCmdlet.MyInvocation.MyCommand.Name
#This is the problematic line:
ScriptBlock = [scriptblock]::Create("`$_ | $($PSCmdlet.MyInvocation.MyCommand.Name) -Parallel:`$false -fn:$fn -sqlQuery:$SQLQuery -option:$option -List:$List")
}
if ($_ -and $_ -isnot [string]) { $serverName=$_ } else { $serverName=$InputObject.name }
@(if ($_ -and $_ -isnot [string]) { $_ } else { $InputObject }) | Start-RSJob @jobArguments | Out-Null
} #endregion
}
end {#region Wait for results and return them
if ($Parallel) {
Get-RSJob -batch $batch | Wait-RSJob -ShowProgress | Out-Null
}#endregion
}
}
$obj = New-Object -TypeName PSObject -Property @{
Name = 'server1'
Other = 'other'
}
$list2 = $obj
$list3 = "item1-item2"
$list2 | foo -fn 'Manage' -number 2 -option Q -List $list3
这是错误:
输入对象不能绑定到命令的任何参数,因为命令不接受管道输入,或者输入及其属性与接受管道输入的任何参数都不匹配。
有谁知道如何使它工作,以便我可以将列表传递到运行空间?
