convert ruby hash to URL query string … without those square brackets

Question

In Python, I can do this:

>>> import urlparse, urllib
>>> q = urlparse.parse_qsl(\"a=b&a=c&d=e\")
>>> urllib.urlencode(q)
\'a=         


        

Answer 1

In modern ruby this is simply:

require 'uri'
URI.encode_www_form(hash)
