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.

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

Definition at line 372 of file AuthenticationRequest.php.

References $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.

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

Referenced by MediaWiki\Auth\AuthenticationRequest\getUniqueId(), 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.

Returns
array A (possibly nested) array with primitive types

Definition at line 135 of file AuthenticationRequest.php.

◆ getRequestByClass()

◆ 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

◆ 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$dataSubmitted data as an associative array (keys will correspond to getFieldInfo())
Returns
bool Whether the request data was successfully loaded

◆ 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[]

◆ mergeFieldInfo()

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

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

Parameters
AuthenticationRequest[]$reqs
Returns
array
Exceptions

Member Data Documentation

◆ $action

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

The AuthManager::ACTION_* constant this request was created to be used for.

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

◆ $required

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

For login, continue, and link actions, one of self::OPTIONAL, self::REQUIRED, or self::PRIMARY_REQUIRED.

Definition at line 61 of file AuthenticationRequest.php.

Referenced by MediaWiki\Auth\ButtonAuthenticationRequest\__construct(), and MediaWiki\Auth\AuthenticationRequest\mergeFieldInfo().

◆ $returnToUrl

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

Return-to URL, in case of redirect.

Definition at line 64 of file AuthenticationRequest.php.

◆ $username

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

Username.

See AuthenticationProvider::getAuthenticationRequests() for details of what this means and how it behaves.

Definition at line 68 of file AuthenticationRequest.php.

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

◆ OPTIONAL

◆ PRIMARY_REQUIRED

const MediaWiki\Auth\AuthenticationRequest::PRIMARY_REQUIRED = 2

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

Since the user can choose which primary to authenticate with, the request might or might not end up being actually required.

◆ 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.
