How do I safely join relative url segments?

Question

I\'m trying to find a robust method of joining partial url path segments together. Is there a quick way to do this?

I tried the following:

puts URI::

Use this code:

File.join('resource/', '/edit', '12?option=test').
     gsub(File::SEPARATOR, '/').
     sub(/^\//, '')
# => resource/edit/12?option=test

example with empty strings:

File.join('', '/edit', '12?option=test').
     gsub(File::SEPARATOR, '/').
     sub(/^\//, '')
# => edit/12?option=test

Or use this if possible to use segments like resource/, edit/, 12?option=test and where http: is only a placeholder to get a valid URI. This works for me.

URI.
  join('http:', 'resource/', 'edit/', '12?option=test').
  path.
  sub(/^\//, '')
# => "resource/edit/12"
