【问题描述】：

我正在尝试创建一个返回网站绑定信息的函数。这是为了降低我的 dsc 资源文件的复杂性，该文件将有 20/30 个网站，基于节点名称具有类似的绑定信息。以下是我目前所拥有的，但我遇到了一个错误，我不知道如何解决它。对此的任何帮助将不胜感激。

这是我目前拥有的：

configuration DscTest
{
    Import-DscResource -ModuleName xWebAdministration;

    Node localhost
    {
        xWebsite TestWebSite
        {
            Ensure = "Present"
            Name = "TestWebSite"
            PhysicalPath = "C:\inetpub\test"
            BindingInfo = (Get-TestBindingInformation $Node)
        }
    }
}

function Get-TestBindingInformation
{
    [OutputType([Microsoft.Management.Infrastructure.CimInstance[]])]
    param(
        [System.Collections.Hashtable] $node
    )

    return @(
        New-CimInstance -ClassName MSFT_xWebBindingInformation -Namespace root/microsoft/Windows/DesiredStateConfiguration -Property @{
            Port                  = 80
            Protocol              = "HTTP"
            HostName              = "test1"
        } -ClientOnly

        New-CimInstance -ClassName MSFT_xWebBindingInformation -Namespace root/microsoft/Windows/DesiredStateConfiguration -Property @{
            Port                  = 80
            Protocol              = "HTTP"
            HostName              = "test2"
        } -ClientOnly
    )
}

DscTest

这是我得到的错误：

【问题讨论】：

你能弄清楚如何预处理/计算你的绑定吗？我也有类似情况
似乎不可能。至少不使用当前版本的 ps/dsc

不支持这种直接指定 CimInstance 的方式。您只能在配置块下创建 MSFT_xWebBindingInformation 对象和该对象。这是示例：

配置 DscTest { Import-DscResource -ModuleName xWebAdministration;

Node localhost
{
    $bindingInfo = @()
    Get-TestBindingInformation $Node| foreach {
        $bindingInfo += MSFT_xWebBindingInformation {Port = $_.Port; Protocol = $_.Protocol; HostName = $_.HostName}
    }
    xWebsite TestWebSite
    {
        Ensure = "Present"
        Name = "TestWebSite"
        PhysicalPath = "C:\inetpub\test"
        BindingInfo = $bindingInfo
    }
}

}

函数 Get-TestBindingInformation { [输出类型（[Microsoft.Management.Infrastructure.CimInstance[]]）] 参数（ [System.Collections.Hashtable] $节点 )

return @(
    New-CimInstance -ClassName MSFT_xWebBindingInformation -Namespace root/microsoft/Windows/DesiredStateConfiguration -Property @{
        Port                  = 80
        Protocol              = "HTTP"
        HostName              = "test1"
    } -ClientOnly

    New-CimInstance -ClassName MSFT_xWebBindingInformation -Namespace root/microsoft/Windows/DesiredStateConfiguration -Property @{
        Port                  = 80
        Protocol              = "HTTP"
        HostName              = "test2"
    } -ClientOnly
)

}

Dsc测试
