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.

Authentication providers that expect user input need to implement one or more subclasses of this class and return them from AuthenticationProvider::getAuthenticationRequests(). A typical subclass would override getFieldInfo() and set $required.

Stability: stable: to extend

Since: 1.27

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, MediaWiki\Auth\ConfirmLinkAuthenticationRequest, and MediaWiki\Auth\PasswordDomainAuthenticationRequest.

Definition at line 407 of file AuthenticationRequest.php.

◆ 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.

Stability: stable: to override

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\PasswordAuthenticationRequest, MediaWiki\Auth\PasswordDomainAuthenticationRequest, and MediaWiki\Auth\TemporaryPasswordAuthenticationRequest.

Definition at line 243 of file AuthenticationRequest.php.

◆ getFieldInfo()

MediaWiki\Auth\AuthenticationRequest::getFieldInfo ( )

abstract

Fetch input field info.

This will be used in the AuthManager APIs and web UIs to define API input parameters / form fields and to process the submitted data.

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. Used in API documentation. To add a help text to the web UI, use the AuthChangeFormFields hook.
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). When multiple fields have the same name, they will be merged (see AuthenticationRequests::mergeFieldInfo).

Returns: array As above

Referenced by AuthManagerSpecialPage\hasOwnSubmitButton(), and MediaWiki\Auth\AuthenticationRequest\loadFromSubmission().

◆ 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.

Stability: stable: to override

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

Definition at line 149 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.

◆ 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.

Stability: stable: to override

Returns: string

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

Referenced by MediaWiki\Auth\AuthenticationRequest\describeCredentials(), ApiRemoveAuthenticationData\execute(), and ApiAuthManagerHelper\loadAuthenticationRequests().

◆ 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

\UnexpectedValueException If multiple different usernames are present.

◆ loadFromSubmission()

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

Initialize form submitted form data.

The default behavior is 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.

Stability: stable: to override

Parameters

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

Returns: bool Whether the request data was successfully loaded

Reimplemented in MediaWiki\Auth\CreateFromLoginAuthenticationRequest.

Definition at line 166 of file AuthenticationRequest.php.

References MediaWiki\Auth\AuthenticationRequest\getFieldInfo().

◆ loadRequestsFromSubmission()

static MediaWiki\Auth\AuthenticationRequest::loadRequestsFromSubmission	(	array	$reqs,
		array	$data )

static

Update a set of requests with form submit data, discarding ones that fail.

Parameters

AuthenticationRequest[]	$reqs
array	$data

Returns: AuthenticationRequest[]

Definition at line 257 of file AuthenticationRequest.php.

◆ mergeFieldInfo()

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

static

Merge the output of multiple AuthenticationRequest::getFieldInfo() calls.

Parameters

AuthenticationRequest[] $reqs

Returns: array

Exceptions

\UnexpectedValueException If fields cannot be merged

Member Data Documentation

◆ $action

string null MediaWiki\Auth\AuthenticationRequest::$action = null

The *_CONTINUE constants are not used here, the corresponding "begin" constant is used instead.

◆ $required

int MediaWiki\Auth\AuthenticationRequest::$required = self::REQUIRED

◆ $username

string null MediaWiki\Auth\AuthenticationRequest::$username = null

◆ PRIMARY_REQUIRED

const MediaWiki\Auth\AuthenticationRequest::PRIMARY_REQUIRED = 2

Indicates that the request is required by a primary authentication provider.

Definition at line 57 of file AuthenticationRequest.php.

◆ REQUIRED

const MediaWiki\Auth\AuthenticationRequest::REQUIRED = 1

Indicates that the request is required for authentication to proceed.

This will only be used for UI purposes; it is the authentication providers' responsibility to verify that all required requests are present.
