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).

我如何在Ruby中做到这一点？

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"
