在PowerShell脚本中，如何检查我是否以管理员权限运行？

在PowerShell脚本中，如何检查我是否以管理员权限运行？

$currentPrincipal = New-Object Security.Principal.WindowsPrincipal([Security.Principal.WindowsIdentity]::GetCurrent())
$currentPrincipal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

（来自命令行安全提示）

在PowerShell中4.0你可以使用需要在你的脚本的顶部：

#Requires -RunAsAdministrator

输出：

无法运行脚本“ MyScript.ps1”，因为它包含一个“ #requires”语句以管理员身份运行。当前的Windows PowerShell会话未以管理员身份运行。使用“以管理员身份运行”选项启动Windows PowerShell，然后尝试再次运行脚本。

function Test-Administrator  
{  
    $user = [Security.Principal.WindowsIdentity]::GetCurrent();
    (New-Object Security.Principal.WindowsPrincipal $user).IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator)  
}

执行以上功能。如果结果为True，则该用户具有管理员权限。

这将检查您是否是管理员，如果不是，则它将以管理员身份在PowerShell ISE中重新打开。

希望这可以帮助！

    $ver = $host | select version
    if ($ver.Version.Major -gt 1)  {$Host.Runspace.ThreadOptions = "ReuseThread"}

    # Verify that user running script is an administrator
    $IsAdmin=[Security.Principal.WindowsIdentity]::GetCurrent()
    If ((New-Object Security.Principal.WindowsPrincipal $IsAdmin).IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator) -eq $FALSE)
    {
      "`nERROR: You are NOT a local administrator.  Run this script after logging on with a local administrator account."
        # We are not running "as Administrator" - so relaunch as administrator

        # Create a new process object that starts PowerShell
        $newProcess = new-object System.Diagnostics.ProcessStartInfo "PowerShell_ise";

        # Specify the current script path and name as a parameter
        $newProcess.Arguments = $myInvocation.MyCommand.Definition;

        # Indicate that the process should be elevated
        $newProcess.Verb = "runas";

        # Start the new process
        [System.Diagnostics.Process]::Start($newProcess);

        # Exit from the current, unelevated, process
        exit
    }

作为上述答案的组合，您可以在脚本开头使用类似以下的内容：

# todo: put this in a dedicated file for reuse and dot-source the file
function Test-Administrator  
{  
    [OutputType([bool])]
    param()
    process {
        [Security.Principal.WindowsPrincipal]$user = [Security.Principal.WindowsIdentity]::GetCurrent();
        return $user.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator);
    }
}

if(-not (Test-Administrator))
{
    # TODO: define proper exit codes for the given errors 
    Write-Error "This script must be executed as Administrator.";
    exit 1;
}

$ErrorActionPreference = "Stop";

# do something

另一种方法是用此行启动脚本，这将在不以管理员权限启动时阻止其执行。

#Requires -RunAsAdministrator
