Question

我有两个单独的PowerShell脚本需要同时运行。一个是信息亭，另一个是检测空闲时间并在信息亭脚本中调用函数的脚本。该功能旨在关闭自助服务终端并重新打开它以清除任何表单数据。唯一的问题是它没有关闭原始信息亭而是打开一个新实例。

我已经尝试将这些脚本合并为一个，但却没有运气让它发挥作用。

这是空闲时间脚本：

Add-Type @'
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

namespace PInvoke.Win32 {

public static class UserInput {

    [DllImport("user32.dll", SetLastError=false)]
    private static extern bool GetLastInputInfo(ref LASTINPUTINFO plii);

    [StructLayout(LayoutKind.Sequential)]
    private struct LASTINPUTINFO {
        public uint cbSize;
        public int dwTime;
    }

    public static DateTime LastInput {
        get {
            DateTime bootTime = DateTime.UtcNow.AddMilliseconds(-Environment.TickCount);
            DateTime lastInput = bootTime.AddMilliseconds(LastInputTicks);
            return lastInput;
        }
    }

    public static TimeSpan IdleTime {
        get {
            return DateTime.UtcNow.Subtract(LastInput);
        }
    }

    public static int LastInputTicks {
        get {
            LASTINPUTINFO lii = new LASTINPUTINFO();
            lii.cbSize = (uint)Marshal.SizeOf(typeof(LASTINPUTINFO));
            GetLastInputInfo(ref lii);
            return lii.dwTime;
        }
    }
}
}
'@

    for ( $i = 1)
    {Write-Verbose ("Idle for " + [PInvoke.Win32.UserInput]::IdleTime)
    Start-Sleep -Seconds 1

    if ([PInvoke.Win32.UserInput]::IdleTime -gt "00:00:10.0000000")
    {Stop-Process -processname kiosk*
    C:\kiosk.exe MakeNewForm
}

用于测试的空闲时间设置为10秒。在生产中当然会更长。

这是自助服务终端脚本：

$mainForm.ShowDialog() | Out-Null

我试过了。。\ idle.ps1，do {} while（），将空闲脚本组合到kiosk脚本的末尾，但在组合它们时没有任何效果。

是否有办法将这些组合或让空闲实际调用该函数并让它在kiosk脚本中运行？

提前感谢您的回复或建议！

Answer 1

你的方法很健全。你需要的是将kiosk脚本的进程id写入持久性的东西，即文本文件。然后，如果需要，可以将其用于空闲脚本以引用并终止原始进程。可以通过内置变量$ pid来访问Powershell会话的当前进程ID。

保存当前会话的进程ID

$pid | Out-File -FilePath c:\kiosk-pid.txt

稍后访问它并使用它来终止进程

Get-Process -PID ([int32](Get-Content -Path C:\kiosk-pid.txt)) | Stop-Process

Answer 2

我完全忘记提到这些将作为.exe运行。我加入的是 stop-process -processname kiosk * ，它现在正在完美运行。再次感谢MFT指出我正确的方向。我将更新上面的脚本以显示更改。

if ([PInvoke.Win32.UserInput]::IdleTime -gt "00:00:10.0000000")
{Stop-Process -processname kiosk*
C:\kiosk.exe MakeNewForm

从脚本调用函数并使其在原始脚本中运行
