powershell - 尝试 self 提升时启动过程抛出错误

Question

不知道为什么尝试自我提升时出现此错误。

param(
    $adminUser
)

# Self-elevate the script to administrator if required

if (-Not ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] 'Administrator')) {
 if ([int](Get-CimInstance -Class Win32_OperatingSystem | Select-Object -ExpandProperty BuildNumber) -ge 6000) {
  $CommandLine = "-File `"" + $MyInvocation.MyCommand.Path + "`" " + $MyInvocation.UnboundArguments
  Start-Process -FilePath PowerShell.exe -Verb Runas -Credential "Chrysalis\$adminUser" -ArgumentList $CommandLine
  Exit
 }
}

错误:

Start-Process : Parameter set cannot be resolved using the specified named parameters.

Answer 1

问题是您没有使用有效的参数集。这是Get-Help Start-Process参数集:

SYNTAX
    Start-Process [-FilePath] <String> [[-ArgumentList] <String[]>] [-Credential <PSCredential>] [-LoadUserProfile] [-NoNewWindow] [-PassThru] [-RedirectStandardError <String>] [-RedirectStandardInput <String>] [-RedirectStandardOutput <String>] 
    [-UseNewEnvironment] [-Wait] [-WindowStyle {Normal | Hidden | Minimized | Maximized}] [-WorkingDirectory <String>] [<CommonParameters>]

    Start-Process [-FilePath] <String> [[-ArgumentList] <String[]>] [-PassThru] [-Verb <String>] [-Wait] [-WindowStyle {Normal | Hidden | Minimized | Maximized}] [-WorkingDirectory <String>] [<CommonParameters>]

您会注意到第一个选项具有 -Credential(尽管您需要一个 PSCredential对象，而不仅仅是用户名)，但是它没有 -Verb参数。第二个选项确实有 -Verb，但没有 -Credential。您可以以其他用户身份运行该流程，也可以以同一用户但已提升身份的身份运行该流程，但是不能一次执行全部操作。您必须以其他用户身份运行它，然后从那里提升。
