我有两个 PowerShell 脚本。一个脚本使用提升的凭据调用另一个 PowerShell 脚本，使用Start-Process。

但是我正在努力使第二个脚本将输出值返回给第一个脚本。

这是脚本 # 1，使用 script1.psl "sender-ip=10.10.10.10" 调用

function getUser($abc) {

    <#Previously created password file in C:\Script\cred.txt, read-host -assecurestring | convertfrom-securestring | out-file C:\Script\cred.txt#>

    $password = get-content C:\Script\cred.txt| convertto-securestring
    $credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist "DOMAIN\Username",$password
    $output = start-process powershell -Credential $credentials -ArgumentList '-noexit','-File', 'C:\script\script2.ps1', $abc
    return $output
}

[string]$abc = $args

getUser($abc)

Write-host Output is $output

当我执行脚本时，输出是

Output is

这里是 script2，它将所需的值输出到 cmd 窗口，而不是将值返回到脚本 1：

$userID = $NULL
$line_array = @()
$multi_array = @()
[hashtable]$my_hash = @{}

foreach ($i in $args) {
   $line_array+= $i.split(" ")
}

foreach ($j in $line_array) {
    $multi_array += ,@($j.split("="))
}

foreach ($k in $multi_array) {
    $my_hash.add($k[0],$k[1])
}

$Sender_IP = $my_hash.Get_Item("sender-ip")

<# Gather information on the computer corresponding to $Sender_IP #>
$Win32OS = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $Sender_IP

<# Determine the build number #>
$Build = $Win32OS.BuildNumber


<# Running Windows Vista with SP1 and later, i.e. $Build is greater than or equal to 6001 #>
if ($Build -ge 6001) {
    $Win32User = Get-WmiObject -Class Win32_UserProfile -ComputerName $Sender_IP
    $Win32User = $Win32User | Sort-Object -Property LastUseTime -Descending
    $LastUser = $Win32User | Select-Object -First 1
    $UserSID = New-Object System.Security.Principal.SecurityIdentifier($LastUser.SID)
    $userId = $UserSID.Translate([System.Security.Principal.NTAccount])
    $userId = $userId.Value
}

<# Running Windows Vista without SP1 and earlier, i.e $Build is less than or equal to 6000 #>
elseif ($Build -le 6000) {
    $SysDrv = $Win32OS.SystemDrive
    $SysDrv = $SysDrv.Replace(":","$")
    $ProfDrv = "\\" + $Sender_IP + "\" + $SysDrv
    $ProfLoc = Join-Path -Path $ProfDrv -ChildPath "Documents and Settings"
    $Profiles = Get-ChildItem -Path $ProfLoc
    $LastProf = $Profiles | ForEach-Object -Process {$_.GetFiles("ntuser.dat.LOG")}
    $LastProf = $LastProf | Sort-Object -Property LastWriteTime -Descending | Select-Object -First 1
    $userId = $LastProf.DirectoryName.Replace("$ProfLoc","").Trim("\").ToUpper()
}

else{
    $userId = "Unknown/UserID"
}


# Logic block to return the correct value
if ($userId -ne $NULL) {
    return "userId=" + $userId
}
elseif ($userID -eq $NULL)
{
    return "userId=" + $userId
}

我愿意使用其他函数和 cmdlet，但是脚本自动以提升模式运行是绝对必要的，因为第三方程序正在调用脚本 1，它调用脚本 2，因此脚本 2 需要将值发送回脚本 1，进入第三方程序。

（我在一个问题ProcessStartInfo 和 Process in PowerShell - Authentication Error 中发布了更新的问题）。

您可以使用ProcessStartInfo和Process来读取 StandardOutput。

这是您可能会执行的操作的示例：

$startInfo = New-Object System.Diagnostics.ProcessStartInfo
$startInfo.FileName = "powershell.exe"
$startInfo.Arguments = "C:\script\script2.ps1"

$startInfo.RedirectStandardOutput = $true
$startInfo.UseShellExecute = $false
$startInfo.CreateNoWindow = $false
$startInfo.Username = "DOMAIN\Username"
$startInfo.Password = $password

$process = New-Object System.Diagnostics.Process
$process.StartInfo = $startInfo
$process.Start() | Out-Null
$standardOut = $process.StandardOutput.ReadToEnd()
$process.WaitForExit()

# $standardOut should contain the results of "C:\script\script2.ps1"
$standardOut
