powershell - 如何使用 xWebConfigKeyValue 设置多个 AppSettings 值？

Question

我正在尝试使用 xWebConfigKeyValue DSC 模块资源 xWebAdministration在我们应用程序的 web.config 文件中设置多个值。这是我们配置的摘录，其中包含围绕 web.config 更改的主要事件:

Configuration C4M
{
    Param(
        [Parameter(Mandatory)]
        [string] $BuildDropLocation
    )

    Import-DscResource -Module xWebAdministration  

    Node $AllNodes.NodeName
    {
        $managementPortalInstallPath = 'c:\Company\ManagementPortal'
        File ManagementPortalContents
        {
            DestinationPath = $managementPortalInstallPath
            SourcePath = "$BuildDropLocation\ManagementPortal"
            Type = 'Directory'
            Recurse = $True
        }

        xWebConfigKeyValue RecaptchaPublicKey
        {
            WebsitePath = $managementPortalInstallPath
            ConfigSection = 'AppSettings'
            Key = 'recaptchaPublicKey'
            Value = $Node.RecaptchaPublicKey
            DependsOn = '[File]ManagementPortalContents'
        }

        xWebConfigKeyValue RecaptchaPrivateKey
        {
            WebsitePath = $managementPortalInstallPath
            ConfigSection = 'AppSettings'
            Key = 'recaptchaPrivateKey'
            Value = $Node.RecaptchaPrivateKey
            DependsOn = '[File]ManagementPortalContents'
        }
    }
}

但是当我尝试运行配置时，出现以下错误:

Add-NodeKeys : The key properties combination 'C:\Company\ManagementPortal::AppSettings' is duplicated for keys 'WebsitePath,ConfigSection' of resource 'xWebConfigKeyValue' in node 'myNode'. Please make sure key properties are unique for each resource in a node. At line:160 char:9 + Add-NodeKeys $keyValues $keyNames $keywordName + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [Write-Error], InvalidOperationException + FullyQualifiedErrorId : DuplicateKeyInNode,Add-NodeKeys

看到错误后，我查看了模块 schema.mof 文件，发现 appSettings 键不是 C:\Program Files\WindowsPowerShell\Modules\xWebAdministration\DSCResources\MSFT_xWebConfigKeyValue\MSFT_xWebConfigKeyValue.schema.mof 配置的键:

[ClassVersion("1.0.0.0"), FriendlyName("xWebConfigKeyValue")]
class MSFT_xWebConfigKeyValue : OMI_BaseResource
{
    [Key, Description("Path to website location(IIS or WebAdministration format)")] String WebsitePath;
    [Key, Description("Config Section to be update"), ValueMap{"AppSettings"}, Values{"AppSettings"}] String ConfigSection;
    [Write, ValueMap{"Present","Absent"}, Values{"Present","Absent"}] String Ensure;
    [Required, Description("Key for AppSettings")] String Key;
    [Write, Description("Value for AppSettings")] String Value;
    [Write, Description("If the given key value pair is for attribute, default is element")] Boolean IsAttribute;
};

由于只有站点路径和配置部分是键，因此我不能有多个资源实例指向同一个 appSettings block 但具有不同的 appSetting 键。那么如何配置多个 appSetting 键呢？

Answer 1

您不能在同一配置中配置两个 xWebConfigKeyValue 资源，因为正如您所发现的，资源键仅包含 WebsitePath 和 ConfigSection 属性，并且不区分 Key 属性。

我认为您的直接选择是:

基于xWebConfigKeyValue新建一个cWebConfigKeyValue资源模块，在“cWebConfigKeyValue.schema.mof”中的“Key”属性中添加“Key”属性自行修复。

或者

在单独的配置 block 中定义冲突资源。我不得不在使用 xService 资源的项目中执行此操作。

这些都不是一个特别好的解决方案，但它可能会解除您的障碍，直到出现更好的解决方案。
