Powershell

Question

我正在尝试制作一个日常脚本来检查 URL 列表和 ping 服务器的状态。

我尝试合并 csv，但是 $status 代码的输出与 csv 中的不同

$pathIn = "C:\Users\test\Desktop\URLList.txt"
$URLList = Get-Content -Path $pathIn
$names = gc "C:\Users\test\Desktop\hostnames.txt"

#status code
$result = foreach ($uri in $URLList) {
    try {
        $res = Invoke-WebRequest -Uri $uri -UseBasicParsing -DisableKeepAlive -Method Head -TimeoutSec 5 -ErrorAction Stop
        $status = [int]$res.StatusCode
    }
    catch {
        $status = [int]$_.Exception.Response.StatusCode.value__
    }
    
    # output a formatted string to capture in variable $result
    "$status - $uri"
}

$result

#output to log file
$result | Export-Csv "C:\Users\test\Desktop\Logs.csv"

#ping
$output = $()

foreach ($name in $names) {
    $results = @{ "Host Name" = $name }
    if (Test-Connection -Computername $name -Count 5 -ea 0) {
        $results["Results"] = "Up"
    }
    
    else {
        $results["Results"] = "Down"
    }

    New-Object -TypeName PSObject -Property $results -OutVariable nameStatus
    $output += $nameStatus
}

$output | Export-Csv "C:\Users\test\Desktop\hostname.csv"

#combine the 2 csvs into 1 excel file
$path = "C:\Users\test\Desktop" #target folder
cd $path;
$csvs = Get-ChildItem .\*.csv
$csvCount = $csvs.Count
Write-Host "Detected the following CSV files: ($csvCount)"

foreach ($csv in $csvs) {
    Write-Host " -"$csv.Name
}

Write-Host "--------------------"
$excelFileName = "daily $(get-Date -Format dd-MM-yyyy).xlsx"
Write-Host "Creating: $excelFileName"

foreach ($csv in $csvs) {
    $csvPath = ".\" + $csv.Name
    $worksheetName = $csv.Name.Replace(".csv", "")
    Write-Host " - Adding $worksheetName to $excelFileName"
    Import-Csv -Path $csvPath | Export-Excel -Path $excelFileName -WorkSheetname $worksheetName
}

Write-Host "--------------------"
cd $path;
Get-ChildItem \* -Include \*.csv -Recurse | Remove-Item
Write-Host "Cleaning up"

我想知道

如何更正“日志”中的输出sheet
如果有任何方法可以简化我的脚本以使其更清晰

Answer 1

欢迎来到 SO。您要求审查或重构您的完整脚本。我认为这不是应该使用的方式。相反，您可能会专注于一个特定问题并询问您遇到的具体问题。

我将只关注查询你们服务器状态的部分。你应该停止使用 Write-Host。相反，您应该利用 PowerShell 的独特功能 - 使用丰富而强大的对象而不是愚蠢的文本。 ;-) 我会这样处理查询一堆计算机的任务：

$ComputernameList = Get-Content -Path 'C:\Users\test\Desktop\hostnames.txt'

$Result =
foreach ($ComputerName in $ComputernameList) {
    [PSCustomObject]@{
        ComputerName = $ComputerName
        Online       = Test-Connection -ComputerName $ComputerName -Count 1 -Quiet
    }
}
$result

现在您有一个 PowerShell 对象，您可以通过管道传输到 Export-Csv 或将其用于进一步的步骤。

例如离线计算机的过滤器：

$result | Where-Object -Property Online -NE -Value $true

如果您坚持在脚本运行期间进行可视化控制，您可以使用 Write-Verbose or Write-Debug。这样您可以在需要时打开输出，但在脚本无人值守时忽略它。
