Question

我正在尝试做类似的事情。第一功能第二个功能调用第一个功能并触发开始作业

示例：

Function CreateDeleteDirs {
Param(
  [Parameter(
  Mandatory = $True,
  HelpMessage = 'Remote Path to create dirs on. Provide full path.')
  ]
  [ValidateNotNullOrEmpty()]
  [string]$RootPath
  )
  ***do some stuffs***
}
Function CreateDeleteDirBack {
Param(
  [Parameter(
  Mandatory = $True,
  HelpMessage = 'Remote Path to create dirs on. Provide full path.')
  ]
  [ValidateNotNullOrEmpty()]
  [string]$RootPath
  )
  $scriptBlock = {
 param ($RootPath)
 CreateDeleteDirs -RootPath $RootPath

} 开始作业-ScriptBlock $ scriptBlock -ArgumentList @（$ RootPath） }
}

所以从第二个函数调用CreateDeleteDirs总是失败。我该怎么做

确切的错误代码段

PS C:\Program Files\WindowsPowerShell\Modules> CreateDeleteDirsBackground -RootPath Y: 

Id     Name            PSJobTypeName   State         HasMoreData     Location             Command

我已经修改了您的代码以输出根路径，以便我们可以看到它正在工作并等待作业完成。

$script_block = {
  function CreateDeleteDirs {
    Param(
      [Parameter(Mandatory = $True, HelpMessage = 'Remote Path to create dirs on. Provide full path.')]
      [ValidateNotNullOrEmpty()]
      [string]$RootPath
    )

    write-host "Rootpath = '$RootPath'"
  }

  function CreateDeleteDirBack  {
    Param(
      [Parameter(Mandatory = $True, HelpMessage = 'Remote Path to create dirs on. Provide full path.')]
      [ValidateNotNullOrEmpty()]
      [string]$RootPath
    )

    CreateDeleteDirs -RootPath $RootPath 
  } 
}

Start-Job -InitializationScript $script_block -ScriptBlock {CreateDeleteDirBack  'foo'} | Wait-Job | Receive-Job
