       HTTP::CookieMonster - Easy read/write access to your jar of HTTP::Cookies

VERSION

       version 0.11

SYNOPSIS

           # Use the functional interface for quick read-only access
           use HTTP::CookieMonster qw( cookies );
           use WWW::Mechanize;

           my $mech = WWW::Mechanize->new;
           my $url = 'https://www.nytimes.com';
           $mech->get( $url );

           my @cookies = cookies( $mech->cookie_jar );
           my $cookie  = cookies( $mech->cookie_jar, 'RMID' );
           print $cookie->val;

           # Use the OO interface for read/write access

           use HTTP::CookieMonster;

           my $monster = HTTP::CookieMonster->new( $mech->cookie_jar );
           my $cookie = $monster->get_cookie('RMID');
           print $cookie->val;

           $cookie->val('random stuff');
           $monster->set_cookie( $cookie );

           # now fetch page using mangled cookie
           $mech->get( $url );

DESCRIPTION

       This module was created because messing around with HTTP::Cookies is non-trivial.
       HTTP::Cookies a very useful module, but using it is not always as easy and clean as it
       could be. For instance, if you want to find a particular cookie, you can't just ask for it
       by name.  Instead, you have to use a callback:

           $cookie_jar->scan( \&callback )

       The callback will be invoked with 11 positional parameters:

           0 version
           1 key
           2 val
           3 path
           4 domain
           5 port
           6 path_spec
           7 secure
           8 expires
           9 discard
           10 hash

       That's a lot to remember and it doesn't make for very readable code.

       Now, let's say you want to save or update a cookie. Now you're back to the many positional
       params yet again:

           $cookie_jar->set_cookie( $version, $key, $val, $path, $domain, $port, $path_spec, $secure, $maxage, $discard, \%rest )

       Also not readable. Unless you have an amazing memory, you may find yourself checking the
       docs regularly to see if you did, in fact, get all those params in the correct order etc.

       HTTP::CookieMonster gives you a simple interface for getting and setting cookies. You can
       fetch an ARRAY of all your cookies:

           my @all_cookies = $monster->all_cookies;
           foreach my $cookie ( @all_cookies ) {
               print $cookie->key;
               print $cookie->val;
               print $cookie->secure;
               print $cookie->domain;
               # etc
           }

       Or, if you know for a fact exactly what will be in your cookie jar, you can fetch a cookie
       by name.

           my $cookie = $monster->get_cookie( 'plack_session' );

       This gives you fast access to a cookie without a callback, iterating over a list etc. It's
       good for quick hacks and you can dump the cookie quite easily to inspect its contents in a
       highly readable way:

           use Data::Printer;
           p $cookie;

       If you want to mangle the cookie before the next request, that's easy too.

           $cookie->val('woohoo');
           $monster->set_cookie( $cookie );
           $mech->get( $url );

       Or, add an entirely new cookie to the jar:

           use HTTP::CookieMonster::Cookie;
           my $cookie = HTTP::CookieMonster::Cookie->new(
               key       => 'cookie-name',
               val       => 'cookie-val',
               path      => '/',
               domain    => '.somedomain.org',
               path_spec => 1,
               secure    => 0,
               expires   => 1376081877
           );

           $monster->set_cookie( $cookie );
           $mech->get( $url );

   new
       new() takes just one required parameter, which is cookie_jar, a valid HTTP::Cookies
       object.

           my $monster = HTTP::CookieMonster->new( $mech->cookie_jar );

   cookie_jar
       A reader which returns an HTTP::Cookies object.

   all_cookies
       Returns an ARRAY of all cookies in the cookie jar, represented as
       HTTP::CookieMonster::Cookie objects.

           my @cookies = $monster->all_cookies;
           foreach my $cookie ( @cookies ) {
               print $cookie->key;
           }

   set_cookie( $cookie )
       Sets a cookie and updates the cookie jar.  Requires a HTTP::CookieMonster::Cookie object.

           my $monster = HTTP::CookieMonster->new( $mech->cookie_jar );
           my $s = $monster->get_cookie('session');
           $s->val('random_string');

           $monster->set_cookie( $s );

           # You can also add an entirely new cookie to the jar via this method

           use HTTP::CookieMonster::Cookie;
           my $cookie = HTTP::CookieMonster::Cookie->new(
               key       => 'cookie-name',
               val       => 'cookie-val',
               path      => '/',
               domain    => '.somedomain.org',
               path_spec => 1,
               secure    => 0,
               expires   => 1376081877
           );

           $monster->set_cookie( $cookie );

   delete_cookie( $cookie )
       Deletes a cookie and updates the cookie jar.  Requires a HTTP::CookieMonster::Cookie
       object.

   get_cookie( $name )
       Be aware that this method may surprise you by what it returns.  When called in scalar
       context, get_cookie() returns the first cookie which exactly matches the name supplied.
       In many cases this will be exactly what you want, but that won't always be the case.

       If you are spidering multiple web sites with the same UserAgent object, be aware that
       you'll likely have cookies from multiple sites in your cookie jar.  In this case asking
       for get_cookie('session') in scalar context may not return the cookie which you were
       expecting.  You will be safer calling get_cookie() in list context:

           $monster = HTTP::CookieMonster->new( $mech->cookie_jar );

           # first cookie with this name
           my $first_session = $monster->get_cookie('session');

           # all cookies with this name
           my @all_sessions  = $monster->get_cookie('session');

FUNCTIONAL/PROCEDURAL INTERFACE

   cookies
       This function will DWIM.  Here are some examples:

           use HTTP::CookieMonster qw( cookies );

           # get all cookies in your jar
           my @cookies = cookies( $mech->cookie_jar );

           # get all cookies of a certain name/key
           my @session_cookies = cookies( $mech->cookie_jar, 'session_cookie_name' );

           # get the first cookie of a certain name/key
           my $first_session_cookie = cookies( $mech->cookie_jar, 'session_cookie_name' );
