Class Method Details

.build(args) ⇒ Object

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

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

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

#to_mailtextObject Also known as: to_rfc822text
