Powershell 将参数传递给嵌套的启动作业



我正在尝试将参数传递给嵌套作业。

$executepath = "D:nttoolsCoreAutomation$patch.zipfilename$ntupdatefilename"
$sb = {Start-Job -Name $NTUpdate -ScriptBlock {& cmd.exe /c $executepath}}
Invoke-Command -Session $NTSession -ScriptBlock $sb -ArgumentList $executepath

此输出显示命令实际上并未呈现字符串中的参数:

State          : Running
PSComputerName : LKS.nt.isg.local
RunspaceId     : 8a1c9cc2-1cd0-42a6-a1d0-89d977aabf04
HasMoreData    : True
StatusMessage  :
Location       : localhost
Command        : & cmd.exe /c $executepath
JobStateInfo   : Running
InstanceId     : 9e95c0d8-d177-4a1a-9283-56f07ff5f0a8
Id             : 1
Name           : Job1
ChildJobs      : {System.Management.Automation.PSRemotingChildJob}
PSJobTypeName  : BackgroundJob
PSBeginTime    : 5/9/2017 2:00:49 PM
PSEndTime      :

我也尝试在脚本块中添加此参数,结果相同:

$executepath = "D:nttoolsCoreAutomation$patch.zipfilename$ntupdatefilename"
$sb = {Start-Job -Name $NTUpdate -ScriptBlock {param($executepath) & cmd.exe /c $executepath} -ArgumentList $executepath}
Invoke-Command -Session $NTSession -ScriptBlock $sb -ArgumentList $executepath

State          : Running
PSComputerName : LKS.nt.isg.local
RunspaceId     : 7e039382-d8a6-4298-9983-8f3f6fd2a6c3
HasMoreData    : True
StatusMessage  :
Location       : localhost
Command        : param($executepath) & cmd.exe /c $executepath
JobStateInfo   : Running
InstanceId     : 77e80c13-2801-4726-81f4-8c960319cd0b
Id             : 1
Name           : Job1
ChildJobs      : {System.Management.Automation.PSRemotingChildJob}
PSJobTypeName  : BackgroundJob
PSBeginTime    : 5/9/2017 2:08:38 PM
PSEndTime      :

更新:

尝试了评论中列出的内容。没有运气,结果是一样的

$executepath = "D:nttoolsCoreAutomation$patch.zipfilename$ntupdatefilename"
$sb = {param($executepath) Start-Job -Name NTUpdate -ScriptBlock {param($executepath) & cmd.exe /c $executepath} -ArgumentList $executepath}
Invoke-Command -Session $NTSession -ScriptBlock  $sb -ArgumentList $executepath

State          : Running
PSComputerName : LKS.nt.isg.local
RunspaceId     : 7b7b86df-a216-494e-b7e7-2336e6994a06
HasMoreData    : True
StatusMessage  :
Location       : localhost
Command        : param($executepath) & cmd.exe /c $executepath
JobStateInfo   : Running
InstanceId     : 4d5dd307-2158-4b38-b118-987f1e56cb12
Id             : 1
Name           : NTUpdate
ChildJobs      : {System.Management.Automation.PSRemotingChildJob}
PSJobTypeName  : BackgroundJob
PSBeginTime    : 5/9/2017 2:25:19 PM
PSEndTime      :

更新 2 -$using:执行路径

Invoke-Command -Session $NTSession -ScriptBlock {Start-Job -Name NTUpdate -ScriptBlock {& cmd.exe /c $Using:executepath}}

我尝试过,但出现此错误:

The value of the using variable '$using:executepath' cannot be retrieved because it has not been set in the local
session.
+ CategoryInfo          : InvalidOperation: (:) [Start-Job], RuntimeException
+ FullyQualifiedErrorId : UsingVariableIsUndefined,Microsoft.PowerShell.Commands.StartJobCommand
+ PSComputerName        : LKSNTADM01.nt.isg.local

好的,所以如果我理解正确,你在这里的主要问题是,当你查看作业中的命令时,你会看到:

& cmd.exe /c $executepath

当您希望看到:

& cmd.exe /c D:nttoolsCoreAutomationDefect1126511_CD_2017-04-24_1800_A‌​nttest_genlog.cmd

脚本块不会插入字符串变量,因此,如果您想看到它全部展开,您可以做的是将脚本块定义为字符串,然后将其转换为脚本块。

$sbtext = "Start-Job -Name $NTUpdate -ScriptBlock {& cmd.exe /c $executepath}"
$sb = [scriptblock]::Create($sbtext)

这应该会让你得到你想要的结果。
