Question

我正在为MSP的一组交换管理员设置一个小脚本，该脚本包含4个主要功能，并且在这些功能中还有更多功能。我在运行嵌入式功能时遇到了一些麻烦。下面，我举了其中一个“管理团队”功能的示例

我添加了一个Switch（$ option）来查看是否可以解决此问题，最初我有$ option = Read-host-提示“某些文本”

这确实解决了问题，但是在浏览功能时找不到

function Manage-Teams() {
    Write-Host -ForegroundColor Yellow "What would you like to do? <Enable-AddGuests/Home>"
    $option = Write-Host 'Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuest'
    function Enable-AddGuests () {

            #Set specific Group back to $True or $False
            # GroupID is <Name.ExcterDirectoryObjectId>
        $GroupID = get-unifiedgroup -Identity (Read-Host -prompt "object ID or SMTP") | Select-Object -ExpandProperty ExternalDirectoryObjectId
        $SettingID = Get-AzureADObjectSetting -TargetType Groups -TargetObjectID $GroupID | select-object -expandproperty ID
        remove-azureadobjectsetting -id $settingid -targettype Groups -TargetObjectID $GroupID
        $template = Get-AzureADDirectorySettingTemplate | ? {$_.displayname -eq "group.unified.guest"}
        $settingsCopy = $template.CreateDirectorySetting()
        $settingsCopy["AllowToAddGuests"]= True
        New-AzureADObjectSetting -TargetType Groups -TargetObjectId $groupID -DirectorySetting $settingsCopy
    }

    function Disable-AddGuests {

        #Set specific Group back to $True or $False
        # GroupID is <Name.ExcterDirectoryObjectId>
    $GroupID = get-unifiedgroup -Identity (Read-Host -prompt "object ID or SMTP") | Select-Object -ExpandProperty ExternalDirectoryObjectId
    $SettingID = Get-AzureADObjectSetting -TargetType Groups -TargetObjectID $GroupID | select-object -expandproperty ID
    remove-azureadobjectsetting -id $settingid -targettype Groups -TargetObjectID $GroupID
    $template = Get-AzureADDirectorySettingTemplate | ? {$_.displayname -eq "group.unified.guest"}
    $settingsCopy = $template.CreateDirectorySetting()
    $settingsCopy["AllowToAddGuests"]= False
    New-AzureADObjectSetting -TargetType Groups -TargetObjectId $groupID -DirectorySetting $settingsCopy
}
    Switch ($option) 
    {
        Enable-AddGuests {Enable-AddGuests}
        Disable-AddGuests {Disable-AddGuests}
        Home {Home}
    }
}

我希望以下几点：

Answer 1

让我退后一步来补充AdminOfThings' helpful answer：

如果想让嵌套函数在定义它们的函数之外显示，只需直接在该外部范围内定义它们。

默认情况下，像变量一样，嵌套函数在定义的作用域内是本地的，并且在后代作用域中也可见，这样，在相同范围中定义为兄弟姐妹的功能可以相互调用。

在同一作用域中定义所有函数时，可以避免使用script:在（固定）不同作用域中定义函数的尴尬^[1]：

虽然PowerShell 允许修改其他范围，但从健壮性和可维护性的角度来看，通常是个坏主意。

通过从另一个函数内部定义脚本级别的函数，直到第一次调用定义函数后，脚本范围才可以看到它们。

因此，代码结构如下：

# All functions are defined in the same scope, as siblings. Function Enable-AddGuests { # ... } Function Disable-AddGuests { # ... } Function Manage-Teams { $option = Read-Host "Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuests" switch ($option) { 'Enable-AddGuests' { Enable-AddGuests; break } 'Disable-AddGuests' { Disable-AddGuests; break } } }

^{[1]请注意，对于在命令行上粘贴或“点源”（通过脚本，使用运算符.从脚本中）的代码，{{1} }作用域是指 global 作用域。}

Answer 2

似乎您的代码中有错字。

您使用的是Write-Host cmdlet，而不是Read-Host cmdlet。

更改此：

$option = Write-Host 'Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuest'

对此：

$option = Read-Host 'Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuest'

Answer 3

这是脚本的简化版本，用于演示。

Function Manage-Teams {

    $option = Read-Host "Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuests"


    Function script:Enable-AddGuests {
        "Executing Enable-AddGuests"
    }
    Function script:Disable-AddGuests {
        "Executing Disable-AddGuests"
    }

    Switch ($option) {
        'Enable-AddGuests' {Enable-AddGuests}
        'Disable-AddGuests' {Disable-AddGuests}
        Default {"Entered an incorrect option"}
    }
}

输出：

Manage-Teams
Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuests: Enable-AddGuests
Executing Enable-AddGuests
Manage-Teams
Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuests: Disable-AddGuests
Executing Disable-AddGuests
Manage-Teams
Would you like to allow or disable external access? Enable-AddGuests/Disable-AddGuests: HelpMe
Entered an incorrect option

Get-Help Enable-AddGuests

Get-Help Disable-AddGuests

说明：

我将$option更改为使用Read-Host来提示执行者一条消息，然后存储键入的内容作为响应。我将Enable-AddGuests和Disable-AddGuests的范围定为script的范围。我在您的Default语句的Switch条件中添加了内容，使您在没有收到提示时期望的值时可以执行某些操作。

在执行本示例中的Manage-Teams之后，您就可以访问Enable-AddGuests和Disable-AddGuests函数，因为它们的作用域是脚本作用域。默认情况下，这些功能仅在其封闭范围内，即在Manage-Teams内部，而在外部不可见。您也可以使用Tab键完成它们。如果要访问这些功能而不先运行Manage-Teams，则需要在Manage-Teams之外定义和加载它们。
