具有字符串数组参数的PowerShell脚本的计划任务

Question

我创建了一个PowerShell脚本,可以从Management Shell中完美运行.我试图把它安装在Windows Server 2008 R2的计划任务工作,我不能确定如何通过我的字符串数组参数的参数.

这是我的脚本的相关部分:

[CmdletBinding()]
param(
    [Parameter(Mandatory=$true)]
    [String]
        $BaseDirectory,
    [String]
        $BackupMethod = "Full",
    [Int]
        $RemoveOlderThanDays = 0,
    [String]
        $LogDirectory,
    [Int]
        $LogKeepDays = 7,
    [String[]]
        $AdditionalDirectories
)

if ($AdditionalDirectories -and $AdditionalDirectories.Count -gt 0) {
    Write-Host "  Additional Directories to be included:" -ForegroundColor Green
    $AdditionalDirectories | ForEach-Object {
        Write-Host "     $_" -foregroundcolor green
    }
}

给出麻烦的参数是最后一个,$AdditionalDirectories.

来自壳牌:

如果我像这样从Management Shell运行脚本,它可以很好地工作:

.\FarmBackup.ps1 \\SomeServer\Backups Full 0 D:\Logs\Backups 0 "D:\Documents\PowerShell Scripts","D:\SomeFolder"

结果:

   Additional Directories to be included:
      D:/Documents/PowerShell Scripts
      D:/SomeFolder

来自预定任务:

行动: 启动一个程序

程序/脚本: PowerShell.exe

参数: -File"D:\ Documents\PowerShell Scripts\FarmBackup.ps1"\\ SomeServer\Backups Full 0 D:\ Logs\Backups 0"D:\ Documents\PowerShell Scripts","D:\ SomeFolder"

结果:(来自日志文件)

  Additional Directories to be included:
     D:\Documents\PowerShell Scripts,D:\SomeFolder

---

我已经为这些参数尝试了几种不同的方法,但我似乎无法将它们视为字符串数组中的两个单独的字符串.我现在正在对它们进行硬编码,但似乎必须有一种方法可以使这个工作,因为它从shell运行时完全有效.

尝试使用-Co​​mmand开关而不是-File开关,然后使用调用运算符'&'.以下是使用计划任务执行此操作的示例的链接:

就像是:

-Command "& 'D:\Documents\PowerShell Scripts\FarmBackup.ps1' '\\SomeServer\Backups' 'Full' 0 'D:\Logs\Backups' 0 'D:\Documents\PowerShell Scripts','D:\SomeFolder'"

我通过创建包含内容的脚本来测试此解决方案:

param([string[]] $x)
Write-Host $x.Count

然后通过以下两种方式调用它:

powershell -File ".\TestScript.ps1" "what1,what2"

结果:1

和

powershell -Command "& .\TestScript.ps1 what1,what2"

结果:2
