在升高的窗口中调用BAT，然后更改ENV变量 [英] Call a BAT in an elevated window and changing ENV variables before

问题描述

在PowerShell脚本中，我必须在高架窗口中调用批处理文件。
所以我做

In a PowerShell script, I have to call a batch file in an elevated window. So I do

Start-Process my.bat -Verb runas

现在， my.bat 希望有一些ENV变量在原来设置窗口。
但是，由于升高的窗口以admin身份执行，因此我设置为常规用户的变量似乎不会在管理窗口中设置。

Now, my.bat expects to have some of the ENV variables I set on the original window. However, since the elevated window is executed as admin, those variables I set as a regular user don't appear to be set on the admin window.

有没有办法在调用 my.bat 之前在管理窗口中设置ENV var？

Is there a way to set ENV vars in an admin window prior to calling my.bat?

推荐答案

你想要的是不可能的。出于安全考虑，升级的进程不会继承父级的环境。您可以做的是创建一个运行提升的包装脚本，并在运行 my.bat 之前，让该脚本从参数中设置环境变量。

What you want isn't possible. For security reasons elevated processes don't inherit the parent's environment. What you can do is create a wrapper script that you run elevated and have that script set the environment variables from parameters before running my.bat.

默认情况下，IIRCrunas未启用PowerShell脚本，因此包装器脚本必须是批处理文件：

IIRC "runas" isn't enabled for PowerShell scripts by default, so the wrapper script would have to be a batch file:

@echo off

set "VARIABLE1=%1"
set "VARIABLE2=%2"

call "C:\path\to\my.bat"

像这样运行：

Start-Process .\wrapper.ps1 -ArgumentList 'foo', 'bar' -Verb runas
