build

Description

Creates a new URI::MailTo object from components, with syntax checking.

Components can be provided as an Array or Hash. If an Array is used, the components must be supplied as [to, headers].

If a Hash is used, the keys are the component names preceded by colons.

The headers can be supplied as a pre-encoded string, such as "subject=subscribe&cc=address", or as an Array of Arrays like [[‘subject’, ‘subscribe’], [‘cc’, ‘address’]]

Examples:

   require 'uri'

   m1 = URI::MailTo.build(['joe@example.com', 'subject=Ruby'])
   puts m1.to_s  ->  mailto:joe@example.com?subject=Ruby

   m2 = URI::MailTo.build(['john@example.com', [['Subject', 'Ruby'], ['Cc', 'jack@example.com']]])
   puts m2.to_s  ->  mailto:john@example.com?Subject=Ruby&Cc=jack@example.com

   m3 = URI::MailTo.build({:to => 'listman@example.com', :headers => [['subject', 'subscribe']]})
   puts m3.to_s  ->  mailto:listman@example.com?subject=subscribe
