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.

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
                          'httponly' => 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
httponly = cookie1.httponly

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

Attributes

domain[RW]

Domain for which this cookie applies, as a String

expires[RW]

Time at which this cookie expires, as a Time

httponly[R]

True if this cookie is httponly; false otherwise

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 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.
httponly: whether this cookie is a HttpOnly cookie or not (default to

false).  HttpOnly cookies are not available to javascript.

These keywords correspond to attributes of the cookie object.

  @expires = options["expires"]
  @secure = options["secure"] == true
  @httponly = options["httponly"] == true

  super(value)
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 ruby-3.1.2/lib/cgi/cookie.rb, line 155
def self.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
    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

httponly=(val) click to toggle source

Set whether the Cookie is a httponly cookie or not.

val must be a boolean.

  @httponly = !!val
end

inspect() click to toggle source

A summary of cookie string.

 
               # File ruby-3.1.2/lib/cgi/cookie.rb, line 174
def inspect
  "#<CGI::Cookie: #{self.to_s.inspect}>"
end

secure=(val) click to toggle source

Set whether the Cookie is a secure cookie or not.

val must be a boolean.

 
               # File ruby-3.1.2/lib/cgi/cookie.rb, line 125
def secure=(val)
  @secure = val if val == true or val == false
  @secure
end

to_s() click to toggle source

Convert the Cookie to its string representation.

 
               # File ruby-3.1.2/lib/cgi/cookie.rb, line 138
def to_s
  val = collect{|v| CGI.escape(v) }.join("&")
  buf = "#{@name}=#{val}".dup
  buf << "; domain=#{@domain}" if @domain
  buf << "; path=#{@path}"     if @path
  buf << "; expires=#{CGI.rfc1123_date(@expires)}" if @expires
  buf << "; secure"            if @secure
  buf << "; HttpOnly"          if @httponly
  buf
end
