excel - 努力将 PowerShell 作业信息导出到 excel

Question

我有一个 PowerShell 脚本，它作为作业的一部分运行 Web 请求。使用作业运行的脚本 block ，我正在记录端点 Uri 和响应时间。然后在所有工作完成之后，但在我删除工作之前，我试图将结果导出到 excel 中。

代码:

$Code = {
    Param(
        [array]$Domain,
        [array]$Services,
        [array]$TestData,
        [string]$Path
    )

    $Log = @()

    ## Get Random School ##
    $Random = Get-Random -InputObject $TestData -Count 1

    ## Get Random Service ##
    $RandService = Get-Random -InputObject $Services

    ## Get Random Endpoint ## 
    $ServiceEndpoints = Get-Content "$Path\Service.Endpoints.json" | Out-String | ConvertFrom-Json
    $GatewayEndpoints = $ServiceEndpoints.Services.$RandService.Gateway
    $RandomEndpoint = Get-Random -InputObject $GatewayEndpoints

    $Headers = @{
        "Authorization" = "Bearer" + ' ' + $Random.Token
    }

    $Uri = 'https://' + $Domain + $RandomEndpoint

    Try {
        $TimeTaken = Measure-Command -Expression {
            $JsonResponse = Invoke-WebRequest -Uri $Uri -Headers $Headers -ContentType 'application/json' -Method Get -UseBasicParsing
        }
    }
    Catch {
    }

    $ResponseTime = [Math]::Round($TimeTaken.TotalMilliseconds, 1) 

    $LogItem = New-Object PSObject
    $LogItem | Add-Member -type NoteProperty -Name 'Endpoint' -Value $Uri
    $LogItem | Add-Member -type NoteProperty -Name 'Time' -Value $ResponseTime
    $Log += $LogItem 

    Write-Host $Log
}

#Remove all jobs
Get-Job | Remove-Job

#Start the jobs. Max 4 jobs running simultaneously.
foreach($Row in $TestData){
    While ($(Get-Job -state running).count -ge $MaxThreads){
        Start-Sleep -Milliseconds 3
    }
    Start-Job -Scriptblock $Code -ArgumentList $Domain, $Services, $TestData, $Path
}

#Wait for all jobs to finish.
While ($(Get-Job -State Running).count -gt 0) {
    start-sleep 1
}

$Log | Export-XLSX -Path .\Test.Results\Performance\Performance.Test.Log.xlsx -ClearSheet

#Get information from each job.
foreach($Job in Get-Job) {
    $Info = Receive-Job -Id ($Job.Id)
}

#Remove all jobs created.
Get-Job | Remove-Job

我似乎无法从脚本 block 中获取端点 uri 和响应时间。当我尝试导出 $Log ，所发生的只是它创建了一个空的 excel 文件。

写入主机 $Log

@{Endpoint=https://domain/customer/v1/years/2019/marks; Time=1233.3}
@{Endpoint=https://domain/customer/v1/years/2019/marks; Time=2131.7}

您必须返回 $Log在您的脚本 block 中，因为 $Log生活在另一个范围内。您可以返回$Log在您的 $Code脚本 block ，最后通过 Receive-Job 获取.

将您的代码更改为:

$Code = {
    ...
    $Log += $LogItem 

    Write-Host $Log
    $Log # return via pipeline to the caller
}

正如 Niraj Gajjar 的回答所暗示的，您可以使用 Export-Csv cmdlet 创建 Excel 文件:

#Get information from each job.
foreach($Job in Get-Job) {
    Receive-Job -Id ($Job.Id) | Export-CSV -Path .\Test.Results\Performance\Performance.Test.Log.xlsx -Append -NoTypeInformation
}
