PowerShell从Jobs获取日志

我正在使用称为Logging的PowerShell模块。我使用其他Jobs做一些工作，但是不幸的是，我在其中写入的日志没有被Receive-Job命令接收。

function Get-Topic {
    [CmdletBinding(DefaultParameterSetName = "Normal")]
    [OutputType(ParameterSetName = "Normal")]
    [OutputType(ParameterSetName = "AsJob")]
    param (
        [Parameter(Mandatory = $true, ParameterSetName = "Normal")]
        [Parameter(Mandatory = $true, ParameterSetName = "AsJob")]
        [string]
        $ResourceGroupName,

        [Parameter(Mandatory = $true, ParameterSetName = "Normal")]
        [Parameter(Mandatory = $true, ParameterSetName = "AsJob")]
        [string]
        $Namespace,

        [Parameter(Mandatory = $true, ParameterSetName = "Normal")]
        [Parameter(Mandatory = $true, ParameterSetName = "AsJob")]
        [string]
        $Topic,

        [Parameter(Mandatory = $true, ParameterSetName = "AsJob")]
        [switch]
        $AsJob
    )

    if ($AsJob) {
        $PSBoundParameters.Remove('AsJob') | Out-Null
        return Start-ThreadJob -ScriptBlock {
            param(
                [string]$myFunction,
                [System.Collections.IDictionary]$argTable,
                [System.Collections.Concurrent.ConcurrentDictionary[string, hashtable]] $loggingTargets
            )

            $loggingTargets.Keys | ForEach-Object { Add-LoggingTarget -Name $_ -Configuration $loggingTargets[$_] }
            $cmd = [scriptblock]::Create($myFunction)

            & $cmd @argTable
        } -ArgumentList $MyInvocation.MyCommand.Definition, $PSBoundParameters, (Get-LoggingTarget)
    }

    $topicObj = Get-AzServiceBusTopic `
        -ResourceGroupName $ResourceGroupName `
        -Namespace $Namespace `
        -Name $Topic
    Write-Log -Message "Received topic $($topicObj.Name)" -Level INFO
    return $topicObj
}

有什么办法可以将输出重定向到父级Powershell会话？我看到Write-Host可以工作，但是带有Console目标的记录器却不能。任何解决方法？

解决方案如下：

return Start-ThreadJob -StreamingHost (Get-Host) -ScriptBlock {
            param(
                [string]$myFunction,
                [System.Collections.IDictionary]$argTable,
                [System.Collections.Concurrent.ConcurrentDictionary[string, hashtable]] $loggingTargets
            )

            $loggingTargets.Keys | ForEach-Object { Add-LoggingTarget -Name $_ -Configuration $loggingTargets[$_] }
            $cmd = [scriptblock]::Create($myFunction)

            & $cmd @argTable
        } -ArgumentList $MyInvocation.MyCommand.Definition, $PSBoundParameters, (Get-LoggingTarget)

感谢上帝，cmdlet Start-ThreadJob允许这种功能，基本上参数-StreamingHost解决了这笔交易
