Splatting 不适用于参数 -Filter

Question

我有这么长的一行，我想让它更容易阅读：

$Mail = "stantastic@example.com"    
Get-ADUser -Server example.com:3268 -Filter {EmailAddress -eq $Mail} -Properties CN,co,Company,Department,DisplayName,SamAccountName,State,Office,EmailAddress

我听说使用 splatting 很不错，所以我正在尝试：

$Params = @{
    Server = 'example.com:3268'
    Filter = '{ EmailAddress -eq $Mail }'
    Properties = 'CN,co,Company,Department,DisplayName,SamAccountName,State,Office,EmailAddress'
}

Get-ADUser @Params

但是运行这会引发错误：

Get-ADUser : Error parsing query: '{ EmailAddress -eq stantastic@example.com }' Error Message: 'syntax error' at position: '1'.
At line:1 char:1
+ Get-ADUser @Params
+ ~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ParserError: (:) [Get-ADUser], ADFilterParsingException
    + FullyQualifiedErrorId : ActiveDirectoryCmdlet:Microsoft.ActiveDirectory.Management.ADFilterParsingException,Microsoft.ActiveDirectory.Management.Commands.GetADUser

我错过了什么？

您应该将过滤器作为 string 传递给 ActiveDirectory 模块 cmdlet。您在代码中不必要地包含括号：

Get-ADUser -Filter "EmailAddress -eq '$Mail'"

虽然您可以传递 scriptblock，但无论如何它都会隐式地变成 string。此外，当期望 array 为 string.

时，您将属性作为单个 string 传递

正确的做法：

$aduserParams = @{
    Server     = 'example.com:3268'
    Filter     = "EmailAddress -eq '$Mail'"
    Properties = 'CN', 'co', 'Company', 'Department', 'DisplayName', 'SamAccountName', 'State', 'Office', 'EmailAddress'
}
Get-ADUser @aduserParams

我建议检查 Get-Help 参数类型：

Get-ADUser -Filter <string>
[-ResultPageSize <int>]
[-ResultSetSize <System.Nullable[System.Int32]>]
[-SearchBase <string>]
[-SearchScope {Base | OneLevel | Subtree}]
[-AuthType {Negotiate | Basic}]
[-Credential <PSCredential>]
[-Partition <string>]
[-Properties <string[]>]
[-Server <string>]
[<CommonParameters>]
