在Ruby中的字符串中转义双重和单反斜杠 [英] Escape double and single backslashes in a string in Ruby

问题描述

我正尝试以这样一种格式访问Windows平台上的ruby脚本中的网路路径。

I'm trying to access a network path in my ruby script on a windows platform in a format like this.

\\servername\some windows share\folder 1\folder2\

现在如果我试图用这个路径，它不会工作。单个反斜杠未正确转义此脚本。

Now If I try to use this as a path, it won't work. Single backslashes are not properly escaped for this script.

path = "\\servername\some windows share\folder 1\folder2\"
d = Dir.new(path)

我可以想到要正确逃脱路上的斜线。但是我无法逃避那个单反斜杠 - 因为它是特殊的意思。我尝试使用单引号，双引号，转义反斜杠本身，使用替代引号如％Q {}或％q {}，使用ascii进行char转换。在某种意义上说，我没有做到这一点，没有什么可行的。 :-)现在，临时解决方案是映射一个网络驱动器N：\指向该路径并以这种方式访问​​，但这不是解决方案。

I tried everything I could think of to properly escape slashes in the path. However I can't escape that single backslash - because of it's special meaning. I tried single quotes, double quotes, escaping backslash itself, using alternate quotes such as %Q{} or %q{}, using ascii to char conversion. Nothing works in a sense that I'm not doing it right. :-) Right now the temp solution is to Map a network drive N:\ pointing to that path and access it that way, but that not a solution.

任何人都有任何想法如何正确逃脱单反斜杠？

Does anyone have any idea how to properly escape single backslashes?

谢谢

推荐答案

只需将每个反斜杠加倍，如下所示：

Just double-up every backslash, like so:

"\\\\servername\\some windows share\\folder 1\\folder2\\"
