Constructor Details

.new(*arg) ⇒ MailTo

Description

Creates a new MailTo object from generic URL components with no syntax checking.

This method is usually called from URI.parse, which checks the validity of each component.

Class Method Details

.build(args)

Description

Creates a new 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
