#initialize(*arg) ⇒ MailTo

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.

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:[email protected]?subject=Ruby

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

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

#to_mailtext ⇒ Object Also known as: to_rfc822text

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

Example:

require 'uri'

uri = URI.parse("mailto:[email protected]?Subject=subscribe&cc=myaddr")
uri.to_mailtext
# => "To: [email protected]\nSubject: subscribe\nCc: myaddr\n\n\n"
