windows - Powershell 存在本地用户 ADSI

Question

我得到以下代码（工作）：

   #Import File
$Users = Import-Csv C:\Users\Administrator\Desktop\userImport\users.csv

# Setting data
$compname = hostname
$computer = [ADSI]"WinNT://$compname" 
$userGroup = [ADSI]"WinNT://./Users,Group"

# Loop to add all users
$Users | %  { 

    # Create user itself
    $createUser = $computer.Create("User",$_.userid)

    # Set password (print1!)
    $createUser.SetPassword($_.password)
    $createUser.SetInfo()

    # Create extra data
    $createUser.Description = "Import via powershell"
    $createUser.FullName = $_.'full name'
    $createUser.SetInfo()

    # Set standard flags (Password expire / Password change / Account disabled)
    $createUser.UserFlags = 64 + 65536 # ADS_UF_PASSWD_CANT_CHANGE + ADS_UF_DONT_EXPIRE_PASSWD
    $createUser.SetInfo()

    # Adduser to standard user group ("SERVER02\Users")
    $userGroup.Add($createUser.Path)

    # Show that user X as been added
    $username = $_.'full name'
    echo "User  $username added"
}

但是如果用户已经存在，怎么可能建立一个检查呢？我真的在网上找不到任何东西：x

Answer 1

你可以试试这个：

   #Import File
$Users = Import-Csv C:\Users\Administrator\Desktop\userImport\users.csv

# Setting data
$compname = hostname
$computer = [ADSI]"WinNT://$compname" 
$userGroup = [ADSI]"WinNT://./Users,Group"

$localUsers = $computer.Children | where {$_.SchemaClassName -eq 'user'}  |  % {$_.name[0].ToString()}

# Loop to add all users
$Users | %  { 

    if($localUsers -NotContains $_.userID)
    {
      ... do your job here....
    }
    else
    {
      write-host "User $($_.userID) already exists"
    }
}

不幸的是，ADSI 接口似乎在 Windows 8.1 中被破坏了。这是我的解决方法：

if (& net users | select-string "UserName") {
    #  user exists
} else {
    #  user not found
}

您可以使用ExistsADSI 的静态函数来检查用户是否存在：

[ADSI]::Exists('WinNT://./username')

但请注意这一点：[ADSI]::Exists 抛出异常而不是返回 False
