在Ruby中将UNC路径转换为UNC

Question

我想将以下PATH转换为Ruby中的UNC路径。

C：/Users/bla/bla2/asdf-ut-script.js

Answer 1

一个UNC path要求您知道服务器和共享，这两者都不存在于你的路径名，除非你正在寻找的东西，如：
\\localhost\C$\Users\bla\bla2\asdf-ut-script.js

如果这是你想要什么：

def File.to_unc(path, server="localhost", share=nil) 
    parts = path.split(File::SEPARATOR) 
    parts.shift while parts.first.empty? 
    if share 
    parts.unshift share 
    else 
    # Assumes the drive will always be a single letter up front 
    parts[0] = "#{parts[0][0,1]}$" 
    end 
    parts.unshift server 
    "\\\\#{parts.join('\\')}" 
end 

puts File.to_unc("C:/Users/bla/bla2/asdf-ut-script.js") 
#=> \\localhost\C$\Users\bla\bla2\asdf-ut-script.js 

puts File.to_unc("C:/Users/bla/bla2/asdf-ut-script.js", 'filepile') 
#=> \\filepile\C$\Users\bla\bla2\asdf-ut-script.js 

puts File.to_unc("/bla/bla2/asdf-ut-script.js", 'filepile', 'HOME') 
#=> \\filepile\HOME\bla\bla2\asdf-ut-script.js
