为调用命令序列化 PsObject [英] Serializing PsObject for Invoke-Command

问题描述

我正在寻找使用 Invoke-Command 将 PsObject 传递给远程函数的最佳或正确方法.ConvertTo-Xml 适合序列化，但没有内置的反向 cmdlet.我在网上找到的解决方案都是针对特定内容的.

I'm looking for the best or proper way to pass a PsObject to a remote function with Invoke-Command. ConvertTo-Xml is good for serializing but there is no built-in reverse cmdlet. The solutions I've found online are all content specific.

我实现了以下功能，这些功能适用于我测试过的少数对象，但看起来很笨拙.这是要咬我吗?有没有更好但仍然简单的解决方案?

I implemented the following functions which works with the few objects I tested but seems rather hacky. Is this going to bite me? Is there a better, yet still simple solution?

function Get-TmpFileName () {...}

function Serialize-PsObject($obj) {
    $tmpFile = Get-TmpFileName
    Export-Clixml -InputObject $obj -Path $tmpFile
    $serializedObj = Get-Content $tmpFile
    Remove-Item $tmpFile
    $serializedObj
}

function Deserialize-PsObject($obj) {
    $tmpFile = Get-TmpFileName
    $obj > $tmpFile
    $deserializedObj = Import-Clixml $tmpFile
    Remove-Item $tmpFile
    $deserializedObj
}

推荐答案

您是否知道 PowerShell 已经序列化了通过 Invoke-Command 发送的对象?

Are you aware that PowerShell already serializes objects sent through Invoke-Command?

如果由于某种原因这还不够或对您不起作用，那么您可以直接使用自己的内置序列化:

If for some reason that isn't enough or isn't working for you, then you can use use the built-in serialization yourself directly:

$clixml = [System.Management.Automation.PSSerializer]::Serialize($object)
$object = [System.Management.Automation.PSSerializer]::Deserialize($clixml)

.Serialize 有一个重载，您可以在其中指定深度(对于对象内的对象).

.Serialize has an overload where you can specify the depth (for objects within objects).

这些是用于实现 Export-Clixml 和 Import-Clixml 的相同方法(但这些 cmdlet 直接处理文件而不是字符串).

These are the same methods used in implementing Export-Clixml and Import-Clixml (but those cmdlets work directly with files and not strings).
