在导入模块期间访问 PrivateData

我想加载 config.xml 文件的内容并将其存储在$PrivateData当我的模块加载时。这是我的 PSD1 中的定义行

# Private data to pass to the module specified in ModuleToProcess
PrivateData = @{'Variables'=@{};'Config'=$null}

这将创建一个包含两个项目的哈希表。 1）Variables是我用来存储模块私有变量的第二个哈希表。 2) Config 将包含 config.xml 文件的值。 XML 示例：

<Config>
    <Foo>Bar</Foo>
</Config>

我可以使用以下行加载 xml：

$PrivateData  = $MyInvocation.MyCommand.Module.PrivateData
$PrivateData.Config = ([xml](Get-Content $PSScriptRoot\Config.xml | Out-String)).Config

我似乎无法在 PSM1 文件中访问它。我可以将它包装在 Cmdlet 中，如下所示：

Function Initialize-TestModule {
    $PrivateData  = $MyInvocation.MyCommand.Module.PrivateData
    $PrivateData.Config #= ([xml](Get-Content $PSScriptRoot\Config.xml | Out-String)).Config    
}

但随后用户必须拨打电话Import-Module然后第二次致电Initialize-TestModule这是我试图避免的。

如果我将代码放入 PSM1 中，当我调用时它会生成此错误Import-Module

Property 'Config' cannot be found on this object; make sure it exists and is settable.

+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : PropertyNotFound

如果我尝试像这样加载 PSD1：

PrivateData = @{'Variables'=@{};'Config'=([xml](Get-Content $PSScriptRoot\Config.xml | Out-String)).Config}

我收到这些错误：

在我的 PSM1 中尝试拨打电话Initialize-TestModule using Invoke-Command and Start-Job两者都失败了。那么有没有人在期间设法访问 $PrivateDataImport-Module?

您可能需要使用 $MyInspiration 变量访问私有数据。但是，我只是通过从函数内调用它来使其工作。为了将其加载到 PSM1 文件中的变量，我从那里调用该函数。我从https://social.technet.microsoft.com/Forums/windowsserver/en-US/9620af9a-0323-460c-b3e8-68a73715f99d/module-scoped-variable?forum=winserverpowershell https://social.technet.microsoft.com/Forums/windowsserver/en-US/9620af9a-0323-460c-b3e8-68a73715f99d/module-scoped-variable?forum=winserverpowershell.
