我正在使用PowerShell 4.0，我正在尝试将字符串数组作为Invoke-Command -ScriptBlock的参数之一传递，其中我在远程服务器上调用另一个PowerShell脚本。当我这样做时，字符串数组似乎变平，因此它显示为单个字符串值，而不是字符串数组。
下面列出的是第一个脚本，由提供初始参数的Bamboo部署服务器调用。
在Debug部分中，$ SupportFolders字符串数组由FlowerBoxArrayText函数迭代，它正确地将两个文件夹路径写入控制台，如预期的那样。
24-Oct-2017 14:59:33 *****************************************************************************
24-Oct-2017 14:59:33 **** E:\SRSFiles\SRSOutput
24-Oct-2017 14:59:33 **** E:\SRSFiles\SRSBad
24-Oct-2017 14:59:33 *****************************************************************************
这是第一个脚本文件的初始部分，显示输入参数，字符串数组创建以及我通过Invoke-Command调用远程脚本的位置;
[CmdletBinding(DefaultParametersetName='None')]
param (
# Allows you to specify Install, Delete or Check.
[ValidateSet("Install", "Delete", "Check")][string] $Action = "Check",
# Allows you to specify the remote server name.
[string] $ComputerName = "None",
# Allows you to specify the username to use for installing the service.
[string] $Username = "None",
# Allows you to specify the password to use for installing the service.
[string] $Password = "None",
# Allows you to specify the location of the support folders for the service, if used.
[string] $SupportFoldersRoot = "None"
)
Function CreateCredential()
{
$Pass = $Password | ConvertTo-SecureString -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential($Username, $Pass)
Return $Cred
}
Function FlowerBoxArrayText($TextArray, $TextColor="Yellow")
{
Write-Host "*****************************************************************************" -ForegroundColor $TextColor
foreach($TextLine in $TextArray)
{
IndentedText $TextLine $TextColor
}
Write-Host "*****************************************************************************" -ForegroundColor $TextColor
}
Function IndentedText($TextToInsert, $TextColor="Yellow")
{
Write-Host "**** $TextToInsert" -ForegroundColor $TextColor
}
$Credential = CreateCredential
[string[]] $ResultMessage = @()
[string] $Root = $SupportFoldersRoot.TrimEnd("/", "\")
[string[]] $SupportFolders = @("$Root\SRSOutput", "$Root\SRSBad")
#Debug
Write-Host "**** Starting debug in ManageAutoSignatureProcessorService ****"
FlowerBoxArrayText $SupportFolders -TextColor "Green"
Write-Host "**** Ending debug in ManageAutoSignatureProcessorService ****"
#End Debug
$ResultMessage = Invoke-Command -ComputerName $ComputerName -Credential $Credential -ScriptBlock {
param($_action,$_username,$_password,$_supportFolders) &"C:\Services\ManageService.ps1" `
-Action $_action `
-ComputerName DEV `
-Name DevProcessor `
-DisplayName 'DevProcessor' `
-Description 'DevProcessor' `
-BinaryPathName C:\Services\DevProcessor.exe `
-StartupType Manual `
-Username $_username `
-Password $_password `
-ServicePathName C:\Services `
-SupportFolders $_supportFolders `
-NonInteractive } -ArgumentList $Action,$Username,$Password,(,$SupportFolders)
if ($ResultMessage -like '*[ERROR]*')
{
FlowerBoxArrayText $ResultMessage -textColor "Red"
}
else
{
FlowerBoxArrayText $ResultMessage -textColor "Green"
}
然后，在远程服务器上的ManageService.ps1脚本文件中，我有以下内容;
[CmdletBinding(DefaultParametersetName='None')]
param (
# Allows you to specify Install, Delete or Check.
[ValidateSet("Install", "Delete", "Check")][string] $Action = "Check",
# Allows you to specify the name of the remote computer.
[string] $ComputerName = "None",
# Allows you to specify the service name.
[string] $Name = "None",
# Allows you to specify the service display name.
[string] $DisplayName = "None",
# Allows you to specify the service description.
[string] $Description = "None",
# Allows you to specify the path to the binary service executable file.
[string] $BinaryPathName = "None",
# Allows you to specify how the service will start, either manual or automatic.
[ValidateSet("Manual", "Automatic")][string] $StartupType = "Manual",
# Allows you to specify the domain username that the service will run under.
[string] $Username = "None",
# Allows you to specify the password for the domain username that the service will run under.
[string] $Password = "None",
# Allows you to specify the path to the service install scripts and service files on the remote server.
[string] $ServicePathName = "None",
# Allows you to specify the location of the support folders for the service, if used. The default value is an empty array
[string[]] $SupportFolders = @(),
# Disables human interaction, and allows all tests to be run even if they 'fail'.
[switch] $NonInteractive
)
Function CreateCredential()
{
$Pass = $Password | ConvertTo-SecureString -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential($Username, $Pass)
Return $Cred
}
[bool] $OkToInstall = $False
[string[]] $ResultMessage = @()
#Debug
$ResultMessage = $ResultMessage += "[DEBUG] ***************************************"
$ResultMessage = $ResultMessage += "[DEBUG] SupportFolders: [$SupportFolders] ."
foreach ($Folder in $SupportFolders)
{
$ResultMessage = $ResultMessage += "[DEBUG] SupportFolders Item: $Folder."
}
$Count = @($SupportFolders).Count
$ResultMessage = $ResultMessage += "[DEBUG] SupportFolders Count: $Count ."
$ResultMessage = $ResultMessage += "[DEBUG] ***************************************"
#End Debug
这一行，
$ResultMessage = $ResultMessage += "[DEBUG] SupportFolders: [$SupportFolders] ."
显示返回到调用脚本的$ ResultMessage值的以下结果;
**** [DEBUG] SupportFolders: [E:\SRSFiles\SRSOutput E:\SRSFiles\SRSBad] .
请注意，数组已展平。
后面的foreach循环也只打印出一个值而不是两个;
"E:\SRSFiles\SRSOutput E:\SRSFiles\SRSBad"
我花了很多时间研究解决方案，但尚未找到答案。
有什么想法吗？
编辑1使用@Bacon Bits建议;
$Options = @{'Action' = $Action
'ComputerName' = 'DEV'
'Name' = 'DevProcessor'
'DisplayName' = 'DevProcessor'
'Description' = 'Generate daily processes'
'BinaryPathName' = 'C:\Services\DevProcessor\DevProcessor.exe'
'StartupType' = 'Manual'
'Username' = $Username
'Password' = $Password
'ServicePathName' = 'C:\Services\DevProcessor'
'SupportFolders' = $SupportFolders
}
$ScriptBlock = {
param($Options)
& {
param(
$Action,
$ComputerName,
$Name,
$DisplayName,
$Description,
$BinaryPathName,
$StartupType,
$Username,
$Password,
$ServicePathName,
$SupportFolders,
$NonInteractive
)
&powershell "C:\Services\DevProcessor\ManageService.ps1 $Action $ComputerName $Name $DisplayName $Description $BinaryPathName $StartupType $Username $Password $ServicePathName $SupportFolders"
} @Options;
}
$ResultMessage = Invoke-Command -ComputerName $ComputerName -Credential $Credential -ScriptBlock $ScriptBlock -ArgumentList $Options
如果我运行上面列出的修改代码，我仍然会获得$ SuppportFolders的扁平数组，而ManageService.ps1脚本会跳过具有空格的参数，即使它们在我分配它们时也会被引用。
完全包装ManageService.ps1中的代码的选项，而不是简单地调用远程脚本是不可行的，因为ManagedService.ps1脚本相当广泛且通用，因此我可以从我的30多个自动化脚本中调用它部署服务器。
我相信如果包装ManageService脚本是可行的，那么@Bacon Bits建议会起作用。
答案 0 :(得分：1)
要传递单个数组，您可以执行以下操作：
Invoke-Command -Session $Session -ScriptBlock $ScriptBlock -ArgumentList (,$Array);
但是，只有在您只需要传递单个数组时才有效。一旦开始传递多个数组或多个复杂对象，它们就会崩溃。
有时，这会奏效：
Invoke-Command -ScriptBlock $ScriptBlock -ArgumentList (, $Array1), (, $Array2), (, $Array3);
然而，根据我的经验，这可能是不一致的。有时它会再次使阵列变平。
您可以做的与this answer类似。
{param($Options)& <# Original script block (including {} braces)#> @options }
基本上我们做的是：
所以它会是这样的：
$Options = @{
Action = 'Check';
ComputerName = 'XYZ123456';
Name = 'MyName';
.
.
.
}
$ScriptBlock = {
param($Options)
& {
[CmdletBinding(DefaultParametersetName='None')]
param (
# Allows you to specify Install, Delete or Check.
[ValidateSet("Install", "Delete", "Check")][string] $Action = "Check",
# Allows you to specify the name of the remote computer.
[string] $ComputerName = "None",
# Allows you to specify the service name.
[string] $Name = "None",
.
.
.
.
#End Debug
} @Options;
}
Invoke-Command -ComputerName RemoteServer -ScriptBlock $ScriptBlock -ArgumentList $Options;
这是一个简单的工作示例：
$Options = @{
List1 = 'Ed', 'Frank';
List2 = 5;
List3 = 'Alice', 'Bob', 'Cathy', 'David'
}
$ScriptBlock = {
param($Options)
& {
param(
$List1,
$List2,
$List3
)
"List1"
$List1
''
"List2"
$List2
''
"List3"
$List3
} @Options;
}
Invoke-Command -ScriptBlock $ScriptBlock -ArgumentList $Options;
输出：
List1
Ed
Frank
List2
5
List3
Alice
Bob
Cathy
David
请注意，我在PowerShell v5上进行了测试。我不再拥有使用PowerShell v4进行测试的系统。
