Public Class Methods
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']) m1.to_s # => "mailto:joe@example.com?subject=Ruby" m2 = 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 = URI::MailTo.build({:to => 'listman@example.com', :headers => [['subject', 'subscribe']]}) m3.to_s # => "mailto:listman@example.com?subject=subscribe"

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.

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"
# File uri/mailto.rb, line 268 def to_mailtext to = URI.decode_www_form_component(@to) head = '' body = '' @headers.each do |x| case x[0] when 'body' body = URI.decode_www_form_component(x[1]) when 'to' to << ', ' + URI.decode_www_form_component(x[1]) else head << URI.decode_www_form_component(x[0]).capitalize + ': ' + URI.decode_www_form_component(x[1]) + "\n" end end "To: #{to} #{head} #{body} " end
Constructs String from URI

Checks the headers v
component against either

# File uri/mailto.rb, line 208 def check_headers(v) return true unless v return true if v.size == 0 if HEADER_REGEXP !~ v raise InvalidComponentError, "bad component(expected opaque component): #{v}" end true end
