Mojolicious::Sessions(3)

NAME
Mojolicious::Sessions - Session manager based on signed cookies

SYNOPSIS
  use Mojolicious::Sessions;

  my $sessions = Mojolicious::Sessions->new;
  $sessions->cookie_name('myapp');
  $sessions->default_expiration(86400);

DESCRIPTION
Mojolicious::Sessions manages sessions based on signed cookies for Mojolicious. All data gets serialized with Mojo::JSON and stored Base64 encoded on the client-side, but is protected from unwanted changes with a HMAC-SHA256 signature.

ATTRIBUTES
Mojolicious::Sessions implements the following attributes.

  cookie_domain
  my $domain = $sessions->cookie_domain;
  $sessions  = $sessions->cookie_domain('.example.com');

Domain for session cookies, not defined by default.

  cookie_name
  my $name  = $sessions->cookie_name;
  $sessions = $sessions->cookie_name('session');

Name for session cookies, defaults to "mojolicious".

  cookie_path
  my $path  = $sessions->cookie_path;
  $sessions = $sessions->cookie_path('/foo');

Path for session cookies, defaults to "/".

  default_expiration
  my $time  = $sessions->default_expiration;
  $sessions = $sessions->default_expiration(3600);

Default time for sessions to expire in seconds from now, defaults to 3600. The expiration timeout gets refreshed for every request. Setting the value to 0 will allow sessions to persist until the browser window is closed, this can have security implications though. For more control you can also use the "expiration" and "expires" session values.

  # Expiration date in seconds from now (persists between requests)
  $c->session(expiration => 604800);

  # Expiration date as absolute epoch time (only valid for one request)
  $c->session(expires => time + 604800);

  # Delete whole session by setting an expiration date in the past
  $c->session(expires => 1);

  deserialize
  my $cb    = $sessions->deserialize;
  $sessions = $sessions->deserialize(sub ($bytes) {...});

A callback used to deserialize sessions, defaults to "j" in Mojo::JSON.

  $sessions->deserialize(sub ($bytes) { return {} });

  encrypted
  my $bool  = $sessions->encrypted;
  $sessions = $sessions->encrypted($bool);

Use encrypted session cookies instead of merely cryptographically signed ones.

  partitioned
  my $bool  = $sessions->partitioned;
  $sessions = $sessions->partitioned($bool);

Partitioned flag, this is to be used in accordance to the CHIPS amendment to RFC 6265. Note that this attribute is EXPERIMENTAL because even though most commonly used browsers support the feature, there is no specification yet besides this draft <https://www.ietf.org/archive/id/draft-cutler-httpbis-partitioned-cookies-00.html>.

Partitioned cookies are held within a separate cookie jar per top-level site.

  samesite
  my $samesite = $sessions->samesite;
  $sessions    = $sessions->samesite('Strict');

Set the SameSite value on all session cookies, defaults to "Lax".

  # Disable SameSite feature
  $sessions->samesite(undef);

  secure
  my $bool  = $sessions->secure;
  $sessions = $sessions->secure($bool);

Set the secure flag on all session cookies, so that browsers send them only over HTTPS connections.

  serialize
  my $cb    = $sessions->serialize;
  $sessions = $sessions->serialize(sub ($hash) {...});

A callback used to serialize sessions, defaults to "encode_json" in Mojo::JSON.

  $sessions->serialize(sub ($hash) { return '' });

METHODS
Mojolicious::Sessions inherits all methods from Mojo::Base and implements the following new ones.

  load
  $sessions->load(Mojolicious::Controller->new);

Load session data from signed cookie.

  store
  $sessions->store(Mojolicious::Controller->new);

Store session data in signed cookie.
