通过 CMD arguments 到 Powershell

Question

Here the Code:

@echo off
if "%*"=="" (echo Give me the URL! && exit /b)
echo Output :
set /p output=
powershell Invoke-WebRequest -Uri %* -OutFile output

The problem in this code I've written is output variable
how to send that variable into powershell?

Answer 1

Use %output% to expand the output variable - and remember to quote the arguments (otherwise it'll break if someone inputs a path with spaces):

@echo off
if "%*"=="" (echo Give me the URL! && exit /b)
echo Output :
set /p output=
powershell Invoke-WebRequest -Uri '%*' -OutFile '%output%'
