CGI::Cookie

Class representing an HTTP cookie.

In addition to its specific fields and methods, a Cookie instance is a delegator to the array of its values.

See RFC 2965.

Examples of use ↑

cookie1 = CGI::Cookie::new("name", "value1", "value2", ...)
cookie1 = CGI::Cookie::new("name" => "name", "value" => "value")
cookie1 = CGI::Cookie::new('name'    => 'name',
                           'value'   => ['value1', 'value2', ...],
                           'path'    => 'path',   # optional
                           'domain'  => 'domain', # optional
                           'expires' => Time.now, # optional
                           'secure'  => true      # optional
                          )

cgi.out("cookie" => [cookie1, cookie2]) { "string" }

name    = cookie1.name
values  = cookie1.value
path    = cookie1.path
domain  = cookie1.domain
expires = cookie1.expires
secure  = cookie1.secure

cookie1.name    = 'name'
cookie1.value   = ['value1', 'value2', ...]
cookie1.path    = 'path'
cookie1.domain  = 'domain'
cookie1.expires = Time.now + 30
cookie1.secure  = true

Attributes

domain[RW]

Domain for which this cookie applies, as a String

expires[RW]

Time at which this cookie expires, as a Time

name[RW]

Name of this cookie, as a String

path[RW]

Path for which this cookie applies, as a String

secure[R]

True if this cookie is secure; false otherwise

Public Class Methods

new(name_string,*value) click to toggle source
new(options_hash)

Create a new CGI::Cookie object.

name_string

The name of the cookie; in this form, there is no domain or expiration. The path is gleaned from the SCRIPT_NAME environment variable, and secure is false.

*value

value or list of values of the cookie

options_hash

A Hash of options to initialize this Cookie. Possible options are:

name

the name of the cookie. Required.

value

the cookie’s value or list of values.

path

the path for which this cookie applies. Defaults to the the value of the SCRIPT_NAME environment variable.

domain

the domain for which this cookie applies.

expires

the time at which this cookie expires, as a Time object.

secure

whether this cookie is a secure cookie or not (default to false). Secure cookies are only transmitted to HTTPS servers.

These keywords correspond to attributes of the cookie object.

end
parse(raw_cookie) click to toggle source

Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.

cookies = CGI::Cookie::parse("raw_cookie_string")
  # { "name1" => cookie1, "name2" => cookie2, ... }

 
               # File cgi/cookie.rb, line 144
def Cookie::parse(raw_cookie)
  cookies = Hash.new([])
  return cookies unless raw_cookie

  raw_cookie.split(/[;,]\s?/).each do |pairs|
    name, values = pairs.split('=',2)
    next unless name and values
    name = CGI::unescape(name)
    values ||= ""
    values = values.split('&').collect{|v| CGI::unescape(v,@@accept_charset) }
    if cookies.has_key?(name)
      values = cookies[name].value + values
    end
    cookies[name] = Cookie::new(name, *values)
  end

  cookies
end

Public Instance Methods

  @secure
end
to_s() click to toggle source

               # File cgi/cookie.rb, line 126
def to_s
  val = collect{|v| CGI::escape(v) }.join("&")
  buf = "#{@name}=#{val}"
  buf << "; domain=#{@domain}" if @domain
  buf << "; path=#{@path}"     if @path
  buf << "; expires=#{CGI::rfc1123_date(@expires)}" if @expires
  buf << "; secure"            if @secure == true
  buf
end
value() click to toggle source
