计划任务的PowerShell脚本与字符串数组参数 [英] Scheduled Task for PowerShell Script with String Array Parameter

问题描述

我已经创建了一个从命令行管理程序运行完全PowerShell脚本。我试图把它安装在Windows Server 2008 R2的计划任务工作，我不能确定如何传递参数给我字符串数组参数。

I've created a PowerShell script that runs perfectly from the Management Shell. I'm trying to get it setup to work in a scheduled task in Windows Server 2008 R2 and am unsure how to pass the parameters for my string array parameter.

下面是我的脚本的相关部分：

Here is the relevant portion of my script:

[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
    }
}

给予麻烦参数是最后一个， $ AdditionalDirectories 。

如果我运行在命令行管理程序这样的脚本，它完美的作品：

If I run the script from the Management Shell like this, it works perfectly:

.\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

从计划任务：

动作： 启动程序的

程序/脚本： PowerShell.exe 的

参数： - 文件D：\\文档\\ PowerShell脚本进行\\ FarmBackup.ps1\\\\ SomeServer \\备份全0 D：\\日志\\备份0D：\\文档\\ PowerShell的脚本，D：\\ SomeFolder的

结果：（从日志文件）

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

我试过几个这些参数不同的方法，但我似乎无法让他们被视为字符串数组中的2个独立的字符串。我硬编码它们现在，但似乎必须有一种方法，使这项工作，因为从shell中运行时，它是完全有效的。

I've tried a couple of different methods for those parameters but I can't seem to get them to be seen as 2 separate strings in the string array. I'm hardcoding them for now, but it seems like there must be a way to make this work since it's totally valid when run from the shell.

推荐答案

尝试使用 - 命令开关代替 - 文件开关，然后使用调用操作符'和;。这里是与预定任务这样的一个例子的链接：

Try using the -Command switch instead of the -File switch, and then use the invocation operator '&'. Here is a link to an example of doing this with scheduled tasks:

是这样的：

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

我用的内容创建一个脚本测试此解决方案：

I tested this solution by creating a script with the contents:

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

然后把它称为有以下两种方式：

Then called it in the following two ways:

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

与结果：1

和

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

与结果：2
