Ruby, How to add a param to an URL that you don't know if it has any other param already

Question

I have to add a new param to an indeterminate URL, let\'s say param=value.

In case the actual URL has already params like this

http://url.co

More elegant solution:

url       = 'http://example.com?exiting=0'
params    = {new_param: 1}
uri       = URI.parse url
uri.query = URI.encode_www_form URI.decode_www_form(uri.query || '').concat(params.to_a)
uri.to_s #=> http://example.com?exiting=0&new_param=1
