Detailed Description

Manages data for an authenticated session.

A Session represents the fact that the current HTTP request is part of a session. There are two broad types of Sessions, based on whether they return true or false from self::canSetUser():

  • When true (mutable), the Session identifies multiple requests as part of a session generically, with no tie to a particular user.
  • When false (immutable), the Session identifies multiple requests as part of a session by identifying and authenticating the request itself as belonging to a particular user.

The Session object also serves as a replacement for PHP's $_SESSION, managing access to per-session data.

◆ getToken()

MediaWiki\Session\Session::getToken ( $salt = '',
$key = 'default' )

Fetch a CSRF token from the session.

Note that this does not persist the session, which you'll probably want to do if you want the token to actually be useful.

string | string[]$saltToken salt
string$keyToken key
Returns
Token

Definition at line 372 of file Session.php.

◆ getUser()

MediaWiki\Session\Session::getUser ( )

Return the authenticated user for this session.

Definition at line 163 of file Session.php.

◆ hasToken()

MediaWiki\Session\Session::hasToken ( string $key = 'default')

Check if a CSRF token is set for the session.

Since
1.37
Parameters
string$keyToken key
Returns
bool

Definition at line 354 of file Session.php.

◆ isPersistent()

MediaWiki\Session\Session::isPersistent ( )

Indicate whether this session is persisted across requests.

For example, if cookies are set.

Returns
bool

Definition at line 107 of file Session.php.

◆ key()

MediaWiki\Session\Session::key ( )

Definition at line 602 of file Session.php.

◆ next()

MediaWiki\Session\Session::next ( )

Definition at line 608 of file Session.php.

◆ offsetExists()

MediaWiki\Session\Session::offsetExists ( $offset)
Note
Despite the name, this seems to be intended to implement isset() rather than array_key_exists(). So do that.

Definition at line 630 of file Session.php.

◆ offsetGet()

& MediaWiki\Session\Session::offsetGet ( $offset)
Note
This supports indirect modifications but can't mark the session dirty when those happen. SessionBackend::save() checks the hash of the data to detect such changes.
Accessing a nonexistent key via this mechanism causes that key to be created with a null value, and does not raise a PHP warning.

Definition at line 644 of file Session.php.

◆ offsetSet()

MediaWiki\Session\Session::offsetSet ( $offset,
$value )

Definition at line 654 of file Session.php.

◆ offsetUnset()

MediaWiki\Session\Session::offsetUnset ( $offset)

Definition at line 659 of file Session.php.

MediaWiki\Session\Session::persist ( )

Make this session persisted across requests.

If the session is already persistent, equivalent to calling $this->renew().

Definition at line 117 of file Session.php.

◆ remove()

MediaWiki\Session\Session::remove ( $key)
Parameters
string | int$key

Definition at line 339 of file Session.php.

Remove all CSRF tokens from the session.

Definition at line 412 of file Session.php.

Definition at line 88 of file Session.php.

Remove a CSRF token from the session.

The next call to self::getToken() with $key will generate a new secret.

Referenced by MediaWiki\User\TempUser\TempUserCreator\acquireAndStashName().

◆ sessionWithRequest()

Parameters
bool$remember

Definition at line 147 of file Session.php.

◆ setSecret()

string | int$key
mixed$value

Definition at line 477 of file Session.php.

◆ setUser()

User$userUser to set on the session.

Definition at line 200 of file Session.php.

◆ shouldForceHTTPS()

MediaWiki\Session\Session::shouldRememberUser ( )

Indicate whether the user should be remembered independently of the session ID.

Returns
string|null

Definition at line 208 of file Session.php.

◆ unpersist()

MediaWiki\Session\Session::unpersist ( )

Make this session not be persisted across requests.

This will remove persistence information (e.g. delete cookies) from the associated WebRequest(s), and delete session data in the backend. The session data will still be available via get() until the end of the request.

Definition at line 129 of file Session.php.

◆ valid()

MediaWiki\Session\Session::valid ( )

Definition at line 620 of file Session.php.
