RFC2368, The mailto URL scheme
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
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
# File uri/mailto.rb, line 88 def self.build(args) tmp = Util::make_components_hash(self, args) if tmp[:to] tmp[:opaque] = tmp[:to] else tmp[:opaque] = '' end if tmp[:headers] tmp[:opaque] << '?' if tmp[:headers].kind_of?(Array) tmp[:opaque] << tmp[:headers].collect { |x| if x.kind_of?(Array) x[0] + '=' + x[1..-1].to_s else x.to_s end }.join('&') elsif tmp[:headers].kind_of?(Hash) tmp[:opaque] << tmp[:headers].collect { |h,v| h + '=' + v }.join('&') else tmp[:opaque] << tmp[:headers].to_s end end return super(tmp) end
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.
# File uri/mailto.rb, line 131 def initialize(*arg) super(*arg) @to = nil @headers = [] if MAILTO_REGEXP =~ @opaque if arg[-1] self.to = $1 self.headers = $2 else set_to($1) set_headers($2) end else raise InvalidComponentError, "unrecognised opaque part for mailtoURL: #{@opaque}" end end
# File uri/mailto.rb, line 206 def headers=(v) check_headers(v) set_headers(v) v end
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 241 def to_mailtext to = URI::unescape(@to) head = '' body = '' @headers.each do |x| case x[0] when 'body' body = URI::unescape(x[1]) when 'to' to << ', ' + URI::unescape(x[1]) else head << URI::unescape(x[0]).capitalize + ': ' + URI::unescape(x[1]) + "\n" end end return "To: #{to} #{head} #{body} " end
