将文件路径转换为URI

Question

我有一个表示文件路径的字符串，例如“/home/user/dir1/dir2/dir3/name.ext”。现在我想将它转换为合法的URI（以“file：//”开头的字符串等）。

如何在Ruby中执行此操作？

Answer 1

require 'uri' 

uri = URI.join('file:///', '/home/user/dir1/dir2/dir3/name.ext') 
=> #<URI::Generic:0x0000000263fcc0 URL:file:/home/user/dir1/dir2/dir3/name.ext> 

uri.scheme 
=> "file" 
uri.path 
=> "/home/user/dir1/dir2/dir3/name.ext" 
uri.to_s 
=> "file:/home/user/dir1/dir2/dir3/name.ext"
