Windows批处理脚本URL解码 [英] Windows batch script url decoding

问题描述

我有一个批处理脚本，可在我的网络上为我触发vlc，问题是它基于浏览器中的URL打开. 浏览器会自动添加％20代替常规空间，在将文件路径发送到vlc之前，我需要在批处理脚本中再次将其替换为常规空间.

I have a batch script that triggers vlc for me on my network, the problem is it opens based on URLs in a browser. The browser automatically adds the %20 in place of a regular space, and I need to replace this with a regular space again in my batch script before sending the file path on to vlc.

这是我的代码；

@echo off
set str=%1
set str=%str:~8%
set str=%str:%%20= %
START /D "C:\Program Files\VideoLAN\VLC\" vlc.exe %str%
pause

值得一提的是，它将在Windows 7和/或Vista系统上运行.

It is worth mentioning that this will run on a windows 7 and/or vista system.

推荐答案

@echo off
setlocal enabledelayedexpansion
set str=%~1
set str=%str:~7%
set str=!str:%%20= !
"C:\Program Files\VideoLAN\VLC\vlc.exe" "%str%"
pause

也可以自由修复其他问题.如果脚本在参数周围使用引号引起来，则该脚本始终带有尾随".延迟扩展在此处为您提供了第二组变量定界符，从而避免了%带来的麻烦.此外，据我所知，不需要start，除非您严格依赖VLC将其自己的目录作为其启动路径.

Took the liberty of fixing some other things as well. If the script ran with quotes around the argument it always had a trailing " . Delayed expansion gives you a second set of variable delimiters here which avoids the trouble with the %. Furthermore, start isn't needed as far as I can see, unless you critically depend on VLC having its own directory as its startup path.
