post_form

Posts HTML form data to the specified URI object. The form data must be provided as a Hash mapping from String to String. Example:

{ "cmd" => "search", "q" => "ruby", "max" => "50" }

This method also does Basic Authentication iff url.user exists. But userinfo for authentication is deprecated (RFC3986). So this feature will be removed.

Example:

require 'net/http'
require 'uri'

Net::HTTP.post_form URI('http://www.example.com/search.cgi'),
                    { "q" => "ruby", "max" => "50" }
