DEFAULT_PORT = nil
 

A Default port of nil for URI::MailTo
COMPONENT = [ :scheme, :to, :headers ].freeze
 

An Array of the available components for URI::MailTo
Attributes
[R] headers

E-mail headers set by the URL, as an Array of Arrays
[R] to

The primary e-mail address of the URL, as a String
Class Public methods
build(args)

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

new(*arg)

Description

Creates a new URI::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.

to_mailtext()

Returns the RFC822 e-mail text equivalent of the URL, as a String.

Example:

require 'uri'

uri = URI.parse("mailto:ruby-list@ruby-lang.org?Subject=subscribe&cc=myaddr")
uri.to_mailtext
# => "To: ruby-list@ruby-lang.org\nSubject: subscribe\nCc: myaddr\n\n\n"
Also aliased as: to_rfc822text
