运行空格过多的程序 [英] Run programs with too many spaces

问题描述

我有一个在命令提示符下工作正常的命令:

I have a command that works fine with command prompt:

CMD /C ""C:\Program Files (x86)\VideoLAN\VLC\VLC" -vvv "http://www.foo.com:8085/video.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NC8yNy8yMDE3IDEyO==" :sout=#file{dst="F:\\Partition C Backup\\Downloads\\Video\\TESTING.mp4",no-overwrite} :sout-keep""

这里我需要 CMD/C 来返回错误级别.

Here I need CMD /C to return the errorlevel.

这就是我尝试使用 Run 方法在 VBScript 中运行它的方式:

That's how I tried to run this in VBScript using Run method:

WshShell.Run "CMD /C ""C:\Program Files (x86)\VideoLAN\VLC\VLC" -vvv "http://www.foo.com:8085/video.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NC8yNy8yMDE3IDEyO==" :sout=#file{dst="F:\\Partition C Backup\\Downloads\\Video\\TESTING.mp4",no-overwrite} :sout-keep""", 0, False

此命令抛出以下错误:

预期的语句结束(字符:74)

Expected end of statement (Char: 74)

我看到许多关于运行程序及其参数路径中带有空格的类似问题.我尝试将上述命令更改为数百个不同的命令，并在不同位置添加更多双引号，如我在答案中看到的那样，但没有任何效果，每次运行脚本时，都会发生以下错误之一:

I saw many similar questions about running programs with spaces in its and its parameters' paths. I tried changing above command into hundreds of different commands with adding more double quotation marks into different positions as I saw in answers, but nothing worked and everytime I ran the script, one of the following errors occured:

预期的语句结束
系统找不到指定的文件/路径(空)
未终止的字符串常量
应为)"
应为("

Expected end of statement
The system cannot find the file/path specified (null)
Unterminated string constant
Expected ")"
Expected "("

推荐答案

Lankymart 的回答是正确的:

你只需要正确地转义字符串中的引号，规则是每当您想在字符串中显示引号时将其加倍.

You just need to escape the quotes in the string correctly, the rule is whenever you want to show a quote in a string double it.

但是，您在原始代码中仍然有不平衡的双引号(多余的尾随 ").

However, you still have unbalanced double quotes in the original code (a surplus trailing ").

WshShell.Run "CMD /C """"C:\Program Files (x86)\VideoLAN\VLC\VLC"" -vvv ""http://www.foo.com:8085/video.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NC8yNy8yMDE3IDEyO=="" :sout=#file{dst=""F:\\Partition C Backup\\Downloads\\Video\\TESTING.mp4"",no-overwrite} :sout-keep"""

这将作为

CMD /C ""C:\Program Files (x86)\VideoLAN\VLC\VLC" -vvv "http://www.foo.com:8085/video.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NC8yNy8yMDE3IDEyO==" :sout=#file{dst="F:\\Partition C Backup\\Downloads\\Video\\TESTING.mp4",no-overwrite} :sout-keep"

示例 VBScript(特定的可执行文件 cliparserPause.exe 用于模仿 VLC 行为):

Sample VBScript (a particular executable cliparserPause.exe is used to mimic VLC behaviour):

option explicit
On Error GoTo 0
Dim strResult: strResult = Wscript.ScriptName
Dim sCmdToRun, WshShell, intReturn

' CMD /C ""D:\bat\Prog Files (x86)\cliparserPause.exe" -vvv "http://www.foo.com:8085/video.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NC8yNy8yMDE3IDEyO==" :sout=#file{dst="F:\\Partition C Backup\\Downloads\\Video\\TESTING.mp4",no-overwrite} :sout-keep"
sCmdToRun = "CMD /C """"D:\bat\Prog Files (x86)\cliparserPause.exe"" -vvv ""http://www.foo.com:8085/video.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NC8yNy8yMDE3IDEyO=="" :sout=#file{dst=""F:\\Partition C Backup\\Downloads\\Video\\TESTING.mp4"",no-overwrite} :sout-keep"""
strResult = strResult & vbNewLine & sCmdToRun

Set WshShell = WScript.CreateObject("WScript.Shell")
intReturn = WshShell.Run( sCmdToRun, 1, true)
strResult = strResult & vbNewLine & Cstr( intReturn )

Wscript.Echo strResult
Wscript.Quit( intReturn )

输出:
