匯入AD聯系人時如何跳過null&empty？

我將 AD 聯系人匯入新域的腳本失敗，因為某些值為 Null 和 Empty。我將聯系人匯出為 XML。如何使用 IF 陳述句來解決此問題以創建 AD 物件并在 Null 和 Empty 時跳過，但如果有值則填寫它？

匯入腳本

Import-Module ActiveDirectory
$import = Import-Clixml "C:\Users\Downloads\contacts.xml"
foreach($contact in $import){
    $newContact=@{
        path      = "OU=Test,OU=domain,OU=B"
        type      = "Contact"
        Name      = $contact.name
        otherAttributes = @{
            givenname = $contact.givenName
            sn = $contact.sn
            mail = $contact.mail
            displayName = $contact.displayName
            cn = $contact.cn
            co = $contact.co
            company = $contact.company
            l = $contact.l
            mailNickname = $contact.mailNickname
            telephoneNumber = $contact.telephoneNumber
            st = $contact.st
            streetAddress = $contact.streetAddress
            postalcode = $contact.postalcode
            physicalDeliveryOfficeName = $contact.physicalDeliveryOfficeName
            mobile = $contact.mobile
        }
    }
    New-ADObject @newContact
}

uj5u.com熱心網友回復：

一次構建一個OtherAttributes字典，并測驗對應的值是否實際存在：

# ...
Import-Module ActiveDirectory
$import = Import-Clixml "C:\Users\Downloads\contacts.xml"
$potentialAttributes = @(
    'givenName'
    'sn'
    'mail'
    'displayName'
    'cn'
    'co'
    'company'
    'l'
    'mailNickname'
    'telephoneNumber'
    'st'
    'streetAddress'
    'postalcode'
    'physicalDeliveryOfficeName'
    'mobile'
)

foreach($contact in $import){
    $newContact=@{
        path      = "OU=Test,OU=domain,OU=B"
        type      = "Contact"
        Name      = $contact.name
        OtherAttributes = @{}
    }

    foreach($attributeName in $potentialAttributes){
        if(-not [string]::IsNullOrEmpty($contact.$attributeName)){
            $newContact['OtherAttributes'][$attributeName] = $contact.$attributeName
        }
    }
    
    New-ADObject @newContact
}
