Overview

Wolf supports OAuth2.0 authorization. Other applications can use the OAuth2 interface directly, integrated with Wolf's login and account system. and use Wolf's permissions. Wolf's OAuth2 supports 3 types of authorization:

Authorization Code
Password Credentials
Client Credentials

TokenLifetime

The default global lifetime of a Token is 7 days, which can be determined by the environment variable OAUTH_ACCESS_TOKEN_LIFETIME can be modified, in seconds. Also, accessTokenLifetime can be set separately for each application. Reference admin-api/application to add an application Section.

The RefreshToken has a default global lifetime of 30 days, which can be set via the environment variable OAUTH_ REFRESH_TOKEN_LIFETIME can be modified, in seconds. You can also set refreshTokenLifetime separately for each application. Reference admin-api/application to add an application Section.

AuthorizationCode

Authorize

OAuth2 Get Authorization Code Request.

If there is already a token in the request, the interface returns 302 and jumps to the callback address (i.e. redirect_uri). Use the authorizationCode and state as request parameters. The application needs to retrieve OAuth2's AccessToken and the RefreshToken by the authorizationCode

If there is no token in the request, the server automatically redirects the user to Wolf's Rbac Login page and asks the user to login. After success, continue with the authorization operation.

The server can retrieve the token from the request header (x-rbac-token) or the cookie (key is x-rbac-token). The token information is usually added automatically by the browser, without any additional operation.

Method: GET

URL: /wolf/oauth2/authorize

`Query` parameters

Fields	Type	Required	Description
client_id	string	Yes	client_id, which is `Application.id` in Wolf.
response_type	string	Yes	oauth response type, it is `code` here.
state	string	Yes	It is used to prevent CSRF attacks, please refer to OAuth2 RFC for more details. Please make sure to set this value, and check it in the oauth redirect url.

Response Body

When authorization fails:
