arrays - PowerShell - 将扩展参数传递给 Start-Job cmdlet

Question

我们正在尝试创建一个包含变量的数组，然后将该数组作为扩展传递给一个脚本，该脚本将由 Start-Job 运行。但实际上它失败了，我们无法找到原因。也许有人可以帮忙!？

$arguments= @()
$arguments+= ("-Name", '$config.Name')
$arguments+= ("-Account", '$config.Account')
$arguments+= ("-Location", '$config.Location')

#do some nasty things with $config

Start-Job -ScriptBlock ([scriptblock]::create("& .'$ScriptPath' [string]$arguments")) -Name "Test"

它失败了

Cannot validate argument on parameter 'Name'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

    + PSComputerName        : localhost

即使 $config.name 设置正确。

有什么想法吗？

提前致谢!

我使用此方法传递命名参数:

$arguments = 
@{
   Name     = $config.Name
   Account  = $config.Account
   Location = $config.Location
}

#do some nasty things with $config

Start-Job -ScriptBlock ([scriptblock]::create("&'$ScriptPath'  $(&{$args}@arguments)")) -Name "Test"

如果您在本地运行它，它允许您使用与 splat 脚本相同的参数哈希。

这段代码:

$(&{$args}@arguments)

嵌入可扩展字符串将创建参数:参数的值对:

$config = @{Name='configName';Account='confgAccount';Location='configLocation'}
$arguments = 
@{
   Name     = $config.Name
   Account  = $config.Account
   Location = $config.Location
}

"$(&{$args}@arguments)"

-Account: confgAccount -Name: configName -Location: configLocation
