Question

我有一个命令可以正常使用命令提示符：

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。

这就是我尝试使用Run方法在VBScript中运行它的方法：

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

此命令将引发以下错误：

预期声明结束（字符：74）

我看到许多关于在其及其参数路径中运行带空格的程序的类似问题。我尝试将上面的命令改成数百个不同的命令，并在答案中看到不同位置添加更多双引号，但没有任何效果，每次运行脚本时，都会发生以下错误之一：

预期结束声明
  系统找不到指定的文件/路径（null）
  未端接的弦常数
  预期“）”
  预期“（”

Answer 1

如果你跟着this answer，你会发现你的字符串中没有双引号被转义。

^{来自A: Not able to launch bat file form VBScript if path contains a space}
你只需要正确地转义字符串中的引号，规则是每当你想在字符串中显示一个引号加倍时。

所以该行应

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

哪个将作为

运行

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""

更新

@JosefZ在他们的answer中正确地指出原始命令有一个不必要的尾随双引号（"），所以尽管规则是正确的为了得到正确的结果，你试图逃脱的原始命令需要是正确的。我根据你的问题做了一个假设;

＆＃34;我有一个命令可以正常使用命令提示符＆＃34;

原始命令应该是

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""

使用此方法的

将是

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

并导致执行

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"

Answer 2

Lankymart's answer是对的：

您只需要正确地转义字符串中的引号即规则是每当你想在一个字符串中显示一个引号加倍它。

但是，原始代码中仍然存在不平衡的双引号（剩余尾随"）。

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"""

这将以

运行

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）：

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 )
