Cookie::Baker - Cookie string generator / parser


    use Cookie::Baker;
    $headers->push_header('Set-Cookie', bake_cookie($key,$val));
    my $cookies_hashref = crush_cookie($headers->header('Cookie'));


Cookie::Baker provides simple cookie string generator and parser.


This module tries to use Cookie::Baker::XS's crush_cookie by default. If this fails, it will use Cookie::Baker's pure Perl crush_cookie.

There is no XS implementation of bake_cookie yet.


  my $cookie = bake_cookie('foo','val');
  my $cookie = bake_cookie('foo', {
      value => 'val',
      path => "test",
      domain => '',
      expires => '+24h'
  } );

Generates a cookie string for an HTTP response header. The first argument is the cookie's name and the second argument is a plain string or hash reference that can contain keys such as "value", "domain", "expires", "path", "httponly", "secure", "max-age", "samesite".

Cookie's value.
Cookie's domain.
Cookie's expires date time. Several formats are supported:

  expires => time + 24 * 60 * 60 # epoch time
  expires => 'Wed, 03-Nov-2010 20:54:16 GMT'
  expires => '+30s' # 30 seconds from now
  expires => '+10m' # ten minutes from now
  expires => '+1h'  # one hour from now
  expires => '-1d'  # yesterday (i.e. "ASAP!")
  expires => '+3M'  # in three months
  expires => '+10y' # in ten years time (60*60*24*365*10 seconds)
  expires => 'now'  #immediately
If defined, sets the max-age for the cookie.
Cookie's path.
If true, sets HttpOnly flag. false by default.
If true, sets secure flag. false by default.
If defined as 'lax' or 'strict' or 'none' (case-insensitive), sets the SameSite restriction for the cookie as described in the draft proposal <>, which is already implemented in Chrome (v51), Safari (v12), Edge (v16), Opera (v38) and Firefox (v60).
Parses cookie string and returns a hashref.

    my $cookies_hashref = crush_cookie($headers->header('Cookie'));
    my $cookie_value = $cookies_hashref->{cookie_name}


CPAN already has many cookie related modules. But there is no simple cookie string generator and parser module.
