Question

我有一个PowerShell脚本正在作为作业的一部分运行Web请求。使用作业运行的脚本块，我正在记录Endpoint Uri和响应时间。然后在所有作业完成之后但在我删除作业之前，我试图将结果导出到excel。

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

我似乎无法从脚本块中获取端点uri和响应时间。当我尝试导出$Log时，所有发生的事情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}

Answer 1

作业内部的全局变量在主脚本中不可见，因为作业在具有自己的全局空间的新会话中运行。

Answer 2

您必须在脚本块中返回$Log，因为$Log位于另一个作用域中。您可以在$Log脚本块中返回$Code，最后通过Receive-Job获取它。

将代码更改为：

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

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

正如Niraj Gajjar的答案所建议的那样，您可以使用Export-Csv cmdlet创建一个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
}

Answer 3

您可以使用Export-Csv在excel中打开文件。

具有多个作业的示例代码为CSV格式：

$jobs = @() # INITILIZING ARRAY
$jobs += Start-Job { appwiz.cpl } # START JOB 1 AND ADDING TO ARRAY
$jobs += Start-Job { compmgmt.msc } # START JOB 2 AND ADDING TO ARRAY
$jobs += Start-Job { notepad.exe } # START JOB 3 AND ADDING TO ARRAY

foreach ( $job in $jobs) # INTERATION OF JOBS
{
    Export-Csv -InputObject $job "C:\result.csv" -Append # SAVING TO FILE
}

注意：由于深度为1，有些作业的内部属性无法通过CSV转换，但是一些基本属性可用。
