Start-Process 在 ArgumentList 中传递哈希表

Question

考虑以下情况：

内容MyScript.ps1:

Param (
    [String]$CountryCode,
    [String]$FilesPath,
    [String]$KeepassDatabase,
    [String]$KeepassKeyFile,
    [String]$EventLog = 'HCScripts',
    [String]$EventSource,
    [HashTable]$CitrixFarm = @{'Server1' = '6.5'}
)

$CountryCode
$FilesPath
$KeepassDatabase
$KeepassKeyFile
$EventLog
$EventSource
$CitrixFarm

Caller.ps1的内容：

Param (
    $FilesPath = ".\MyScript.ps1",
    $EvenntLog = 'Test',
    $CountryCode = 'BNL',
    $KeepasDatabase,
    $KeepasKeyFile
)

$Arguments = @()
$Arguments += "-EventSource ""$AppName"""
$Arguments += "-EventLog ""$EventLog"""
$Arguments += "-FilesPath ""$((Get-Item $FilesPath).FullName)"""
$Arguments += "-CountryCode ""$CountryCode"""
$Arguments += "-KeepassDatabase ""$((Get-Item $KeepasDatabase).FullName)"""
$Arguments += "-KeepassKeyFile ""$((Get-Item $KeepasKeyFile).FullName)"""
$Arguments += "-CitrixFarm $CitrixFarm"

$StartParams = @{
    Credential   = $Credentials
    ArgumentList = "-File ""$ScriptPath"" -verb runas" + $Arguments
    WindowStyle  = 'Hidden'
}
Start-Process powershell @StartParams

我们似乎找不到为参数 $CitrixFarm 传入 [HashTable] 的方法。怎么可能添加该参数。或者将其传递给 Start-Process 以提升的权限在新的 PowerShell 会话中调用的脚本？

当省略参数 $CitrixFarm 时一切正常。所以问题真的是传递 HashTable.

Answer 1

您应该以 PowerShell 对象表示法传递哈希表，就像您运行来自 PowerShell window.

的脚本一样

如何构造字符串由您决定。

你可以

使用字符串模板
使用快速调用 "@$((ConvertTo-Json $CitrixFarm -Compress) -replace ':','=')"
use a function 转换哈希表对象。

以下实际上是您要实现的目标。

$Arguments = @()
...
$Arguments += "-CitrixFarm @{'Server1' = '6.5'}"

$StartParams = @{
    Credential   = $Credentials
    ArgumentList = "-File ""$ScriptPath"" -verb runas" + $Arguments
    WindowStyle  = 'Hidden'
}
Start-Process powershell @StartParams
