Question

我知道有很多与我相似的例子。我尝试了许多没有真正成功的人。我将我的代码简化为基本问题，希望有人能指出我正确的方向。

function Send-DBBackupToS3
{
  param(
    [Parameter(Mandatory=$true)][string]$p1, 
    [Parameter(Mandatory=$true)][string]$p2, 
    [Parameter(Mandatory=$true)][string]$p3
  )
  try
  { 
    Write-Host "starting process..."
    $TransferAppExe = $p1
    $arguments = '-OnDiskPath', $p2, '-NotificationEmailAddress', $p3
    $ps = Start-Process -FilePath $TransferAppExe -ArgumentList $arguments -Wait -PassThru               
  }
  catch
  {
      # get error record
      [Exception]$e = $_

      # retrieve information about runtime error
      $info = [PSCustomObject]@{
          Exception = $e.Exception.Message
          Reason    = $e.CategoryInfo.Reason
          Target    = $e.CategoryInfo.TargetName
          Script    = $e.InvocationInfo.ScriptName
          Line      = $e.InvocationInfo.ScriptLineNumber
          Column    = $e.InvocationInfo.OffsetInLine
          }
      # output information. Post-process collected info, and log info (optional)
      $info
  }        
}
function Start-DBCopyAndTransfer
{        
    param(     
      [Parameter(Mandatory)]   
      [string]$AppPath,
      [Parameter(Mandatory)]
      [string]$UploadFilePath,
      [Parameter(Mandatory)]
      [string[]]$EmailAddress
    )               
    Write-Host "calling job..."
    Start-Job -Name Send2S3 -ScriptBlock {param($p1, $p2, $p3) Send-DBBackupToS3 -p1 $p1 -p2 $p2 -p3 $p3} -ArgumentList $AppPath,$UploadFilePath,$EmailAddress          
}
Clear-Host

Write-Host "calling function..."
Start-DBCopyAndTransfer -AppPath "C:\FileToS3.exe" -UploadFilePath "C:\chron.cti" -EmailAddress "4321@gmail.com"

我正在尝试将运行.exe。

所需的参数传递给Start-Process cmdlet

结果我如下：

calling function...
calling job...

Id     Name            PSJobTypeName   State         HasMoreData     Location             Command                  
--     ----            -------------   -----         -----------     --------             -------                  
1      Send2S3         BackgroundJob   Running       True            localhost            param($p1, $p2, $p3) S...



PS C:\WINDOWS\system32> Get-Job

Id     Name            PSJobTypeName   State         HasMoreData     Location             Command                  
--     ----            -------------   -----         -----------     --------             -------                  
1      Send2S3         BackgroundJob   Failed        False           localhost            param($p1, $p2, $p3) S...



PS C:\WINDOWS\system32>

我从未见过写主机＆＃34;启动过程......＆＃34; 开火。如果我从 Send-DBBackupToS3 中删除params（硬编码值），它就可以正常工作。谢谢你的时间！

Answer 1

您可以按如下方式传递多个参数：

Start-Process -FilePath $TransferAppExe -ArgumentList $argument1, $argument2, $argument3 -Wait -PassThru

或传递参数列表：

$arguments = $argument1, $argument2, $argument3
Start-Process -FilePath $TransferAppExe -ArgumentList $arguments -Wait -PassThru

或传递包含所有参数的单个字符串：

Start-Process -FilePath $TransferAppExe -ArgumentList "$argument1 $argument2 $argument3" -Wait -PassThru

另外，如果您有WaitForExit参数，则不需要-Wait，因为他们做同样的事情。

我不想回答我自己的问题......但是，如果有人碰到这个问题，我希望他们有解决方案。

$func = {
  function Send-DBBackupToS3
  {
    param(
      [Parameter(Mandatory=$true)][string]$p1, 
      [Parameter(Mandatory=$true)][string]$p2, 
      [Parameter(Mandatory=$true)][string]$p3
    )
    try
    { 
      Write-Host "starting process..."
      $TransferAppExe = $p1
      $arguments = '-OnDiskPath', $p2, '-NotificationEmailAddress', $p3
      Start-Process -FilePath $TransferAppExe -ArgumentList $arguments -Wait -PassThru            
    }
    catch
    {
      # get error record
      [Exception]$e = $_

      # retrieve information about runtime error
      $info = [PSCustomObject]@{
          Exception = $e.Exception.Message
          Reason    = $e.CategoryInfo.Reason
          Target    = $e.CategoryInfo.TargetName
          Script    = $e.InvocationInfo.ScriptName
          Line      = $e.InvocationInfo.ScriptLineNumber
          Column    = $e.InvocationInfo.OffsetInLine
          }
      # output information. Post-process collected info, and log info (optional)
      $info
    }        
  }
}
function Start-DBCopyAndTransfer
{        
    param(     
      [Parameter(Mandatory)]   
      [string]$AppPath,
      [Parameter(Mandatory)]
      [string]$UploadFilePath,
      [Parameter(Mandatory)]
      [string[]]$EmailAddress
    )               
    Write-Host "calling job..."
    $job = Start-Job -Name Send2S3 -InitializationScript $func -ScriptBlock {param($p1, $p2, $p3) Send-DBBackupToS3 -p1 $p1 -p2 $p2 -p3 $p3} -ArgumentList $AppPath,$UploadFilePath,$EmailAddress          
    Receive-Job -Job $job
    Write-Host ('State: {0}' -f $job.State)
}
Clear-Host

Write-Host "calling function..."
Start-DBCopyAndTransfer -AppPath "C:\FileToS3.exe" -UploadFilePath "C:\chron.cti" -EmailAddress "4321@gmail.com"

如何将多个参数传递给PowerShell Start-Job以在后台运行进程？
