在Ubuntu/Orange Pi 5环境下通过终端获取Kiosk模式Chromium的已打开标签页（PowerShell脚本开发场景）

看起来你现在卡在了通过终端准确获取Kiosk模式下Chromium当前打开的标签页这一步，而且想优化现有的PowerShell脚本，让它更像保活工具而非粗暴重启。我结合你的场景给你分点梳理解决方案和优化建议：

一、核心问题：获取Chromium当前打开的标签页（替代BroTab和Session文件方案）

你的核心需求是判断当前标签页是否符合配置，避免不必要的重启。之前尝试的Session文件读取存在更新不及时的问题，这里给你两个更可靠的方案：

1. 推荐：利用Chromium远程调试接口（DevTools Protocol）

Chromium支持通过远程调试端口暴露实时标签页信息，这是最准确的方式，无论Chromium是手动还是终端启动都能正常工作：

步骤1：修改Chromium启动命令，添加远程调试端口参数：

$chrome = "DISPLAY=:0 chromium-browser $link_string --kiosk --disable-session-crashed-bubble --disable-infobars --remote-debugging-port=9222 &> /dev/null &"

步骤2：在PowerShell中调用接口获取标签页：

function Get-ChromiumActiveTabs {
    param([string]$Ip)
    try {
        # 调用远程调试接口获取所有标签页JSON数据
        $tabData = Invoke-RestMethod -Uri "http://$Ip:9222/json" -ErrorAction Stop
        # 提取所有页面类型标签页的URL
        return $tabData | Where-Object { $_.type -eq "page" } | Select-Object -ExpandProperty url
    }
    catch {
        Write-Error "无法获取$Ip的Chromium标签页：$_"
        return @()
    }
}

# 在主循环中使用该函数
$currentTabs = Get-ChromiumActiveTabs -Ip $ip
$expectedTabs = $link_string -split "\s+" | ForEach-Object { $_.Trim() }

# 检查所有预期URL是否都在当前标签页中
$needsRestart = $false
foreach ($url in $expectedTabs) {
    if ($currentTabs -notcontains $url) {
        $needsRestart = $true
        break
    }
}

if ($needsRestart) {
    Write-Host "$ip的标签页不匹配，执行重启..."
    Invoke-PiCommand -Ip $ip -Command $exitchrome -SuppressOutput
    Start-Sleep -Seconds 5
    Invoke-PiCommand -Ip $ip -Command $chrome -SuppressOutput
} else {
    Write-Host "$ip的标签页符合要求，跳过重启"
}

2. 备选方案：通过进程命令行参数判断（仅适用于固定标签页场景）

如果你的场景是脚本启动固定标签页，没有手动添加标签的需求，可以直接检查Chromium进程的命令行参数：

$chromiumCmd = Invoke-PiCommand -Ip $ip -Command "ps aux | grep chromium-browser | grep -v grep"
$needsRestart = -not ($chromiumCmd -match [regex]::Escape($link_string))

这个方案更轻量，但不支持动态标签页的检测。

二、脚本整体优化建议（针对你的需求：函数、错误日志、邮件通知）

1. 重构重复代码为函数，提升可维护性

你提到函数使用有困难，这里给你封装几个核心函数，统一处理SSH执行、错误捕获：

# 通用SSH执行函数，带错误处理
function Invoke-PiCommand {
    param(
        [Parameter(Mandatory=$true)][string]$Ip,
        [Parameter(Mandatory=$true)][string]$Command,
        [switch]$SuppressOutput
    )
    try {
        # 捕获标准输出和错误输出
        $output = ssh orangepi@$Ip -X $Command 2>&1
        if (-not $SuppressOutput) {
            return $output -join "`n"
        }
    }
    catch {
        $errorMsg = "在$Ip执行命令失败：`n命令：$Command`n错误：$_"
        Write-Error $errorMsg
        # 这里可以调用错误日志/邮件通知函数
        Log-Error -Message $errorMsg
        Send-FailureAlert -Ip $Ip -Message $errorMsg
        throw $errorMsg # 可选：终止脚本或继续执行
    }
}

# 获取分辨率的函数（用正则替代字符串索引，更可靠）
function Get-PiResolution {
    param([string]$Ip)
    $xrandrOutput = Invoke-PiCommand -Ip $Ip -Command "xrandr -display :0.0"
    $resMatch = [regex]::Match($xrandrOutput, '(\d{3,4} x \d{3,4})').Value
    return $resMatch
}

2. 添加错误日志与邮件通知

# 错误日志函数
function Log-Error {
    param([string]$Message)
    $logPath = "C:\temp\display_management_errors.log"
    $logEntry = "[$(Get-Date -Format 'yyyy-MM-dd HH:mm:ss')] $Message"
    Add-Content -Path $logPath -Value $logEntry -Encoding UTF8
}

# 邮件通知函数
function Send-FailureAlert {
    param(
        [string]$Ip,
        [string]$Message
    )
    $smtpParams = @{
        SmtpServer = "你的SMTP服务器地址"
        From = "display-monitor@yourdomain.com"
        To = "admin@yourdomain.com"
        Subject = "显示终端$Ip异常告警"
        Body = "异常详情：`n$Message"
        Port = 587 # 或你的SMTP端口
        UseSsl = $true
        Credential = (Get-Credential -Message "输入SMTP凭据") # 或存储在安全字符串中
    }
    Send-MailMessage @smtpParams -ErrorAction SilentlyContinue
}

3. 优化保活与重启逻辑

把“每30分钟强制重启”改成“定时检查（比如每5分钟），仅在异常时重启”
替换粗暴的killall -9为温和的终止，避免Session文件损坏：

# 先尝试正常关闭，失败再强制杀死
$exitchrome = "killall chromium-browser &>/dev/null; sleep 3; killall -9 chromium-browser &>/dev/null; exit;"

4. 时间处理优化（支持所有月份的月末更新）

你原来的$Calendar.Day -eq '28'不够通用，改成自动判断当月最后一天：

$isLastDayOfMonth = $Calendar.Day -eq [DateTime]::DaysInMonth($Calendar.Year, $Calendar.Month)
if ($isLastDayOfMonth -and $Calendar -gt $updatestart -and $Calendar -lt $updatecutoff) {
    Write-Host "$ip执行月末系统更新..."
    Invoke-PiCommand -Ip $ip -Command "sudo apt-get update; sudo apt-get upgrade -y; sudo reboot;"
    Start-Sleep -Seconds 60
}

三、你提供的原始脚本格式化版本

    $textfile = $_;
    $pos = $textfile.IndexOf("|") ## LOOK FOR PIPE CHARECTER IN TEXT FILE
    $link_string = $textfile.Substring($pos+1) ## CONTENTS AFTER PIPE CHARECTER

    echo $ip

    }

    $MATICS = select-string -pattern "xxx.my.leadermes.com" -InputObject $link_string ## LOOK FOR MATICS URL

    if ($MATICS -ne $null)
    {
