如何将空格分隔的变量传递到 bat 文件中？

Question

我想将一个空格分隔的变量传递到一个批处理文件中，例如：

c:\applications\mi_pocess.bat A1 1AA

当我跑echo %1进去的时候mi_process它回来了A1

我将如何识别A1 1AA为单个字符串？

我试过在我的外部软件中用双引号包裹它

c:\applications\mi_pocess.bat + chr$(34) + A1 1AA + Chr$(34)

而echo %1现在返回"A1 1AA"（我不想在变量引号）

谢谢

我相信大家都知道，%1，%2，等内.BAT代表传递到在命令行中的.bat编号的参数。

如果您将它们用作%~1,%~2等。如果它们在那里，所有周围的引号将被自动删除。

考虑这个space-in-args.bat进行测试：

@echo off
echo.  %1
echo.    (original first argument echo'd)
echo.
echo. "%1"
echo.    (original first argument with additional surrounding quotes)
echo.
echo.  %~1
echo.    (use %%~1 instead of %%1 to remove surrounding quotes, should there be)
echo.
echo. "%~1"
echo.    (we better use "%%~1" instead of "%%1" in this case:
echo.      1. ensure, that argument is quoted when used inside the batch;
echo.      2. avoid quote doubling should the user have already passed quotes.
echo.

运行：

space-in-args.bat "a b c d e"

输出是：

 "a b c d e"
     (original first argument echo'd)

""a b c d e""
     (original first argument with additional surrounding quotes)

  a b c d e
     (using %~1 instead of %1 removes surrounding quotes, should there be some)

 "a b c d e"
     (we better use "%~1" instead of "%1" in this case:
       1. ensure, that argument is quoted when used inside the batch;
       2. avoid quote doubling should the user have already passed quotes.
