The OAuth extension implements an OAuth server in MediaWiki that supports both the OAuth 1.0a and OAuth 2.0 protocol versions. It allows third party developers to securely develop applications ("consumers"), to which users can give a limited set of permissions ("grants"), so that the application can use the MediaWiki action API on the user's behalf.
Voraussetzungen
- OAuth relies on the object cache for temporary tokens and sessions. This should work as long as cache configuration settings are sane. (Older versions required Memcached explicitly.)
- Currently, only MySQL and SQLite database backends are supported
- If the MediaWiki installation is private (i.e. users need to log in to have read access), Special:OAuth will need to be added to the white list.
Installation
- Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens
OAuth
im Ordnerextensions/
ablegen.
Entwickler und Code-Beitragende sollten stattdessen die Erweiterung von Git installieren, mit:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/OAuth - Wird von git aus installiert, ist Composer auszuführen, um PHP-Abhängigkeiten zu installieren, indem
composer install --no-dev
im Erweiterungsverzeichnis ausgeführt wird. (Siehe task T173141 für mögliche Komplikationen.) - Folgenden Code am Ende deiner LocalSettings.php -Datei einfügen:
wfLoadExtension( 'OAuth' );
- Führe das Aktualisierungsskript aus, welches automatisch die notwendigen Datenbanktabellen erstellt, die diese Erweiterung braucht.
- Configure the general parameters as required.
- Configure the user rights by putting them into the relevant groups in
$wgGroupPermissions
. - Erledigt – Navigiere zu Special:Version in deinem Wiki, um zu überprüfen, ob die Erweiterung erfolgreich installiert wurde.
Vagrant-Installation:
- Wird Vagrant benutzt, ist mit
vagrant roles enable oauth --provision
zu installieren
To assign a permission to some group, for example to sysops, you add following line to LocalSettings.php
:
$wgGroupPermissions['sysop']['mwoauthproposeconsumer'] = true;
Konfiguration
Parameters
Variablenname | Standardwert | Beschreibung |
---|---|---|
$wgMWOAuthCentralWiki
|
false
|
Wiki ID of OAuth management wiki. On wiki farms, it makes sense to set this to a wiki that acts as a portal site, is dedicated to management, or just handles login/authentication. It can, however, be set to any wiki in the farm. For single-wiki sites or farms where each wiki manages consumers separately, it should be left as false .
|
$wgMWOAuthSharedUserIDs
|
false
|
(veraltet) Verwende stattdessen $wgMWOAuthSharedUserSource
Whether shared global user IDs are stored in the oauth tables.
On wiki farms with a central authentication system (with integer user IDs) that share a single OAuth management wiki, this must be set to true.
If wikis have a central authentication system but have their own OAuth management, then this can be either |
$wgMWOAuthSharedUserSource
|
null
|
Central ID provider when sharing OAuth credentials over a wiki farm
Source of shared user IDs, if enabled. If CentralIdLookup is available, this is the $providerId for CentralIdLookup::factory(). Generally null would be what you want, to use the default provider. If that class is not available or the named provider is not found, this is passed to the OAuthGetUserNamesFromCentralIds, OAuthGetLocalUserFromCentralId, OAuthGetCentralIdFromLocalUser, OAuthGetCentralIdFromUserName hooks. This has no effect if $wgMWOAuthSharedUserIDs is set to false. |
$wgMWOAuthRequestExpirationAge
|
2.592.000 (30 days)
|
Seconds after which an idle request for a new Consumer is marked as "expired" |
$wgMWOAuthSecureTokenTransfer
|
true
|
Require SSL/TLS for returning Consumer and user secrets. This is required by RFC 5849, however if a wiki wants to use OAuth, but doesn't support SSL, this option makes this configuration possible. This should be set to true for most production settings. |
$wgOAuthSecretKey
|
$wgSecretKey
|
A secret configuration string (random 32-bit string generated using "base64_encode(random_bytes(32))") used to hmac the database-stored secret to produce the shared secrets for Consumers. This provides some protection against an attacker reading the values out of the consumer table (the attacker would also need $wgOAuthSecretKey to generate valid secrets), and some protection against potential weaknesses in the secret generation. If this string is compromised, the site should generate a new $wgOAuthSecretKey, which will invalidate Consumer authorizations that use HMAC/shared secret signatures instead of public/private keys. Consumers can regenerate their new shared secret by using the "Reset the secret key to a new value" option under Special:MWOAuthConsumerRegistration/update. If null, the value is set to $wgSecretKey. |
$wgOAuthGroupsToNotify
|
[]
|
The list of user groups which should be notified about new consumer proposals. Setting this will only have an effect when Echo is installed. |
$wgMWOauthDisabledApiModules
|
[]
|
List of API module classes to disable when OAuth is used for the request |
$wgMWOAuthReadOnly
|
false
|
Prevent write activity to the database. When this is set, consumers cannot be added or updated, and new authorizations are prohibited. Authorization headers for existing authorizations will continue to work. Useful for migrating database tables |
$wgMWOAuthSessionCacheType
|
$wgSessionCacheType
|
The storage mechanism for session data. If null, it defaults to $wgSessionCacheType. |
$wgOAuthAutoApprove
|
[]
|
Allows automatic immediate approval of low-risk apps. In the form of [ 'grants' => [ 'grant1', 'grant2', ... ] ]
|
$wgOAuth2EnabledGrantTypes
|
[
"authorization_code",
"refresh_token",
"client_credentials"
]
|
List of OAuth2 grants that client applications can be allowed to use. Actual grants client application will be allowed to use can be any subset of grants listed here. Grants, other than the ones listed here, are considered legacy grants, and are not supported by this extension |
$wgOAuth2PrivateKey
|
""
|
Private key or a path to the private key used to sign OAuth2 JWT being transmitted. See the OAuth 2.0 Server documentation for how to generate the keys. |
$wgOAuth2PublicKey
|
""
|
Public key or a path to the public key used to verify OAuth2 resource requests. |
$wgOAuth2RequireCodeChallengeForPublicClients
|
true
|
Controls whether clients are required to send code challenges with OAuth2 requests. This only applies to non-confidential clients. |
$wgOAuth2GrantExpirationInterval
|
"PT1H" (1 hour)
|
Controls validity period for access tokens (stored in the cache configured in MWOAuthSessionCacheType). Does not apply to owner-only clients, whose access tokens are always non-expiring. Accepts ISO 8601 durations or can be set to "infinity" or false for non-expiring tokens. |
$wgOAuth2RefreshTokenTTL
|
"P1M" (1 month)
|
Controls validity period for refresh tokens (stored in the cache configured in MWOAuthSessionCacheType). Accepts ISO 8601 durations or can be set to "infinity" or false for non-expiring tokens. |
