Detailed Description

This is a value object for authentication requests.

An AuthenticationRequest represents a set of form fields that are needed on and provided from a login, account creation, password change or similar form.

Since: 1.27

Definition at line 37 of file AuthenticationRequest.php.

Member Function Documentation

◆ __set_state()

static MediaWiki\Auth\AuthenticationRequest::__set_state ( $data )

static

Implementing this mainly for use from the unit tests.

Parameters

array $data

Returns: AuthenticationRequest

Reimplemented in MediaWiki\Auth\ButtonAuthenticationRequest, CaptchaAuthenticationRequest, MediaWiki\Auth\PasswordDomainAuthenticationRequest, and MediaWiki\Auth\ConfirmLinkAuthenticationRequest.

Definition at line 372 of file AuthenticationRequest.php.

References $data, $ret, and as.

◆ describeCredentials()

MediaWiki\Auth\AuthenticationRequest::describeCredentials ( )

Describe the credentials represented by this request.

This is used on requests returned by AuthenticationProvider::getAuthenticationRequests() for ACTION_LINK and ACTION_REMOVE and for requests returned in AuthenticationResponse::$linkRequest to create useful user interfaces.

Returns

Message[] with the following keys:

provider: A Message identifying the service that provides the credentials, e.g. the name of the third party authentication service.
account: A Message identifying the credentials themselves, e.g. the email address used with the third party authentication service.

Reimplemented in MediaWiki\Auth\TemporaryPasswordAuthenticationRequest, MediaWiki\Auth\PasswordAuthenticationRequest, MediaWiki\Auth\PasswordDomainAuthenticationRequest, and TOTPAuthenticationRequest.

Definition at line 225 of file AuthenticationRequest.php.

References MediaWiki\Auth\AuthenticationRequest\getUniqueId().

◆ getFieldInfo()

MediaWiki\Auth\AuthenticationRequest::getFieldInfo ( )

abstract

Fetch input field info.

The field info is an associative array mapping field names to info arrays. The info arrays have the following keys:

type: (string) Type of input. Types and equivalent HTML widgets are:
- string: <input type="text">
- password: <input type="password">
- select: <select>
- checkbox: <input type="checkbox">
- multiselect: More a grid of checkboxes than <select multi>="">
- button: <input type="submit"> (uses 'label' as button text)
- hidden: Not visible to the user, but needs to be preserved for the next request
- null: No widget, just display the 'label' message.
options: (array) Maps option values to Messages for the 'select' and 'multiselect' types.
value: (string) Value (for 'null' and 'hidden') or default value (for other types).
label: (Message) Text suitable for a label in an HTML form
help: (Message) Text suitable as a description of what the field is
optional: (bool) If set and truthy, the field may be left empty
sensitive: (bool) If set and truthy, the field is considered sensitive. Code using the request should avoid exposing the value of the field.
skippable: (bool) If set and truthy, the client is free to hide this field from the user to streamline the workflow. If all fields are skippable (except possibly a single button), no user interaction is required at all.

All AuthenticationRequests are populated from the same data, so most of the time you'll want to prefix fields names with something unique to the extension/provider (although in some cases sharing the field with other requests is the right thing to do, e.g. for a 'password' field).

Returns: array As above

◆ getMetadata()

MediaWiki\Auth\AuthenticationRequest::getMetadata ( )

Returns metadata about this request.

This is mainly for the benefit of API clients which need more detailed render hints than what's available through getFieldInfo(). Semantics are unspecified and left to the individual subclasses, but the contents of the array should be primitive types so that they can be transformed into JSON or similar formats.

Returns: array A (possibly nested) array with primitive types

Reimplemented in CaptchaAuthenticationRequest.

Definition at line 135 of file AuthenticationRequest.php.

◆ getRequestByClass()

static MediaWiki\Auth\AuthenticationRequest::getRequestByClass	(	array	$reqs,
			$class,
			$allowSubclasses = `false`
	)

static

Select a request by class name.

Parameters

AuthenticationRequest[]	$reqs
string	$class	Class name
bool	$allowSubclasses	If true, also returns any request that's a subclass of the given class.

Returns: AuthenticationRequest|null Returns null if there is not exactly one matching request.

Definition at line 253 of file AuthenticationRequest.php.

References $req, $requests, captcha-old\count, and use.

◆ getUniqueId()

MediaWiki\Auth\AuthenticationRequest::getUniqueId ( )

Supply a unique key for deduplication.

When the AuthenticationRequests instances returned by the providers are merged, the value returned here is used for keeping only one copy of duplicate requests.

Subclasses should override this if multiple distinct instances would make sense, i.e. the request class has internal state of some sort.

This value might be exposed to the user in web forms so it should not contain private information.

Returns: string

Reimplemented in MediaWiki\Auth\ConfirmLinkAuthenticationRequest, and MediaWiki\Auth\ButtonAuthenticationRequest.

Definition at line 85 of file AuthenticationRequest.php.

Referenced by MediaWiki\Auth\AuthenticationRequest\describeCredentials().

◆ getUsernameFromRequests()

static MediaWiki\Auth\AuthenticationRequest::getUsernameFromRequests ( array $reqs )

static

Get the username from the set of requests.

Only considers requests that have a "username" field.

Parameters

AuthenticationRequest[] $reqs

Returns: string|null

Exceptions

◆ loadFromSubmission()

MediaWiki\Auth\AuthenticationRequest::loadFromSubmission ( array $data )

Initialize form submitted form data.

The default behavior is to to check for each key of self::getFieldInfo() in the submitted data, and copy the value - after type-appropriate transformations - to $this->$key. Most subclasses won't need to override this; if you do override it, make sure to always return false if self::getFieldInfo() returns an empty array.

Parameters

array $data Submitted data as an associative array (keys will correspond to getFieldInfo())
