将小PS脚本转换为.BATch文件中的长行

标签： windows powershell batch-file cmd

我有从this question的答案获得的PowerShell代码;它显示运行PS代码的cmd.exe窗口的位置/尺寸：

$WindowFunction,$RectangleStruct = Add-Type -MemberDefinition @'
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);
[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
    public int Left;
    public int Top;
    public int Right;
    public int Bottom;
}
'@ -Name "type$([guid]::NewGuid() -replace '-')" -PassThru

$MyWindowHandle = (Get-Process -Id (Get-WmiObject Win32_Process -Filter "ProcessId=$PID").ParentProcessId).MainWindowHandle

$WindowRect = New-Object -TypeName $RectangleStruct.FullName
$null = $WindowFunction::GetWindowRect($MyWindowHandle,[ref]$WindowRect)

Write-Host $WindowRect.Left $WindowRect.Top $WindowRect.Right $WindowRect.Bottom

当我从命令行在.ps1脚本中运行此代码时，它可以正常工作：

C:\Users\Antonio\Documents\test> powershell Set-ExecutionPolicy -ExecutionPolicy
Unrestricted -Scope Process; .\test.ps1
26 -7 943 738

我想在.BATch文件中插入此代码，以便没有单独的.ps1文件，因此我必须在长行中编写相同的代码作为powershell命令的参数。但是，为了保持可读性，我想在.bat文件中使用单独的行，并使用批继续符^终止每一行;这是我的第一次尝试：

@echo off

PowerShell  ^
   $WindowFunction,$RectangleStruct = Add-Type -MemberDefinition '^
   [DllImport("user32.dll", SetLastError = true)]  ^
   [return: MarshalAs(UnmanagedType.Bool)]  ^
   public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);  ^
   [StructLayout(LayoutKind.Sequential)]  ^
   public struct RECT  ^
   {  ^
      public int Left;  ^
      public int Top;  ^
      public int Right;  ^
      public int Bottom;  ^
   }  ^
   ' -Name "type$([guid]::NewGuid() -replace '-')" -PassThru;  ^
   $MyWindowHandle = (Get-Process -Id (Get-WmiObject Win32_Process -Filter "ProcessId=$PID").ParentProcessId).MainWindowHandle;  ^
   $WindowRect = New-Object -TypeName $RectangleStruct.FullName;  ^
   $null = $WindowFunction::GetWindowRect($MyWindowHandle,[ref]$WindowRect);  ^
   Write-Host $WindowRect.Left $WindowRect.Top $WindowRect.Right $WindowRect.Bottom
%End PowerShell%

运行此批处理文件时，会报告几个错误：

C:\Users\Antonio\Documents\test> test.bat
Add-Type : c:\Users\Antonio\AppData\Local\Temp\yhd4ckqv.0.cs(8) : El nombre
'user32' no existe en el contexto actual

+ $WindowFunction,$RectangleStruct = Add-Type -MemberDefinition '

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~

and a long et cetera....

我试图将撇号传递到下面的行，用引号改变撇号，反之，在每行的开头删除了额外的空格和其他几个修改，但我找不到正确的方法来编写这段代码。我以相同的方式编写了几个PS代码段之前比这个大得多，没有任何问题。虽然我是一名经验丰富的程序员，但我是PowerShell的新手，而且它的多重特性一直困扰着我......

在批处理文件中编写此PS代码的正确方法是什么？如果还包括对问题原因的简单解释，我将不胜感激......

双引号文字必须转义为\" 

@echo off

前一段时间有a topic on DosTips解决了这个问题。您可以使用简单的标题创建批处理/ Powershell混合：

<# :
:: Header to create Batch/PowerShell hybrid
@echo off
setlocal
set "POWERSHELL_BAT_ARGS=%*"
if defined POWERSHELL_BAT_ARGS set "POWERSHELL_BAT_ARGS=%POWERSHELL_BAT_ARGS:"=\"%"
endlocal & powershell -NoLogo -NoProfile -Command "$_ = $input; Invoke-Expression $( '$input = $_; $_ = \"\"; $args = @( &{ $args } %POWERSHELL_BAT_ARGS% );' + [String]::Join( [char]10, $( Get-Content \"%~f0\" ) ) )"

:: Any batch code that gets run after your PowerShell goes here
goto :EOF
#>

只需在#>之后抛出您的Powershell代码，并将该文件另存为常规.bat脚本。在你的情况下：

<# :
:: Header to create Batch/PowerShell hybrid
@echo off
setlocal
set "POWERSHELL_BAT_ARGS=%*"
if defined POWERSHELL_BAT_ARGS set "POWERSHELL_BAT_ARGS=%POWERSHELL_BAT_ARGS:"=\"%"
endlocal & powershell -NoLogo -NoProfile -Command "$_ = $input; Invoke-Expression $( '$input = $_; $_ = \"\"; $args = @( &{ $args } %POWERSHELL_BAT_ARGS% );' + [String]::Join( [char]10, $( Get-Content \"%~f0\" ) ) )"
goto :EOF
#>

$WindowFunction,$RectangleStruct = Add-Type -MemberDefinition @'
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);
[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
    public int Left;
    public int Top;
    public int Right;
    public int Bottom;
}
'@ -Name "type$([guid]::NewGuid() -replace '-')" -PassThru

$MyWindowHandle = (Get-Process -Id (Get-WmiObject Win32_Process -Filter "ProcessId=$PID").ParentProcessId).MainWindowHandle

$WindowRect = New-Object -TypeName $RectangleStruct.FullName
$null = $WindowFunction::GetWindowRect($MyWindowHandle,[ref]$WindowRect)

Write-Host $WindowRect.Left $WindowRect.Top $WindowRect.Right $WindowRect.Bottom

我会在这里选择-EncodedCommand选项。您只需对整个powershell脚本进行Base64编码，然后将Base64字符串作为参数传递给powershell.exe：

（假设脚本在这里：C:\Path\To\Script.ps1） 

PS C:\> $ScriptText  = Get-Content C:\Path\To\Script.ps1 -Raw
PS C:\> $ScriptBytes = [System.Text.Encoding]::Unicode.GetBytes($ScriptText)
PS C:\> $EncCommand  = [System.Convert]::ToBase64String($ScriptBytes)

$EncCommand现在包含Base64编码命令，可以在cmd.exe内使用（或者您的批处理文件）：

C:\>powershell -EncodedCommand JABXAGkAbgBkAG8AdwBGAHUAbgBjAHQAaQBvAG4ALAAkAFIAZQBjAHQAYQBuAGcAbABlAFMAdAByAHUAYwB0ACAAPQAgAEEAZABkAC0AVAB5A
