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 Gem::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 'rubygems/vendor/uri/lib/uri'

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

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

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