这是我正在尝试做的事情的存根:
function Set-test {
[CmdletBinding()]
param(
[Parameter(Mandatory=$True,
ValueFromPipeline=$True)]
[object[]]$inputObject
)
Write-Verbose "Set-test: input obj= $inputObject"
PROCESS {
foreach ($obj in $inputobject) {
Write-Output $obj
}
}
}
function Get-test {
$obj = New-Object PSObject
$obj | Add-Member -MemberType NoteProperty -Name "swName" -Value "banana"
$obj | Add-Member -MemberType NoteProperty -Name "Version" -Value "3.2.2"
Write-Output "obj = $obj"
$obj | Set-test -verbose
}
输出如下:
PS > Get-test
obj = @{swName=banana; Version=3.2.2}
VERBOSE: Set-test: input obj=
Get-Process : Cannot evaluate parameter 'Name' because its argument is specified as a script block and there is no input. A script block cannot be evaluated without input.
At C:\Users\username\Documents\WindowsPowerShell\Modules\mytool\mytools.psm1:204 char:13
+ PROCESS {
+ ~
+ CategoryInfo : MetadataError: (:) [Get-Process], ParameterBindingException
+ FullyQualifiedErrorId : ScriptBlockArgumentNoInput,Microsoft.PowerShell.Commands.GetProcessCommand
从详细输出可以看出,对象似乎没有通过管道传输到函数,这让我很困惑。

您不能在 begin{}、process{} 或 end{} 块之外的 set-test 中使用 write-verbose。这会把事情搞乱。如果您将其移动到 process{} 块内,它就可以正常工作。
