Where do I need to URL-encode POST data?

Where should I URL-encode my POST request data? For each param, or for the whole query line?

For example, I have this code:

@VIEWSTATE = url_encode(@VIEWSTATE)
data = ("__EVENTTARGET=&__EVENTARGUMENT=&__LASTFOCUS=&__VIEWSTATE=#{@VIEWSTATE}&__EVENTVALIDATION=#{@EVENTVALIDATION}&=ctl0.......
headers = {
  'Cookie' => cookie,
***
}

resp, data = http.post(path, data, headers)

Is it right, or must I write:

@VIEWSTATE = @VIEWSTATE
    data = url_encode("__EVENTTARGET=&__EVENTARGUMENT=&__LASTFOCUS=&__VIEWSTATE=#{@VIEWSTATE}&__EVENTVALIDATION=#{@EVENTVALIDATION}&=ctl0.......
    headers = {
      'Cookie' => cookie,
    ***
    }

    resp, data = http.post(path, data, headers)

Which is right, and which is better?

I generally like to use URI's encode_www_form which takes either an array or a hash of name/value pairs. This is the example from the documentation:

require 'uri'

URI.encode_www_form([["q", "ruby"], ["lang", "en"]])
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => "ruby", "lang" => "en")
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => ["ruby", "perl"], "lang" => "en")
#=> "q=ruby&q=perl&lang=en"
URI.encode_www_form([["q", "ruby"], ["q", "perl"], ["lang", "en"]])
#=> "q=ruby&q=perl&lang=en"
