PowerShell自定义改密函数Set-UserPassword无法接收管道输入求助

你编写的Set-UserPassword函数里，ComputerName参数没有开启按管道属性名绑定的特性，只有User、NewPassword参数加了ValueFromPipelineByPropertyName = $true配置，所以管道传入的自定义对象的ComputerName属性无法自动绑定到对应参数上，导致调用缺失必选参数无法正常运行。

只需要给Set-UserPassword的ComputerName参数也加上ValueFromPipelineByPropertyName = $true配置即可，修改后的函数完整代码如下：

function Set-UserPassword
{
    [CmdletBinding()]
    param
    (
        [Parameter(Mandatory = $true,
                   Position = 0,
                   ValueFromPipelineByPropertyName = $true)] # 新增此配置项
        [string]$ComputerName,
        [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true,
                   Position = 1)]
        [string]$User,
        [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true,
                   Position = 2)]
        [string]$NewPassword,
        [Parameter(Position = 3,ValueFromPipelineByPropertyName = $true)]
        [string]$PasswordVersion
    )
    
    PROCESS
    {
        if ($env:COMPUTERNAME -eq $ComputerName)
        {
            Set-UserPasswordLocaly $User $NewPassword
        }
        else
        {
            Set-UserPasswordRemotely $ComputerName $User $NewPassword
        }
    }
}

修复后可以省去手动循环的写法，直接用管道批量调用，代码更简洁：

$x = @(
    [pscustomobject]@{
        ComputerName   = 'smzmi0027d'
        User           = 'localadmin'
        NewPassword    = 'djkufdjkuf1234'
    },
    [pscustomobject]@{
        ComputerName   = 'smzmi0027d'
        User           = 'localadmin'
        NewPassword    = '1'
    }
)
# 直接管道传入即可执行，无需手动遍历
$x | Set-UserPassword | Out-GridView
