Auth JWT

This module requires the pyjwt library to be installed.

This module lets developpers add a new jwt authentication method on Odoo controller routes.

To use it, you must:

• Create an auth.jwt.validator record to configure how the JWT token will be validated.
• Add an auth="jwt_{validator-name}" or auth="public_or_jwt_{validator-name}" attribute to the routes you want to protect where {validator-name} corresponds to the name attribute of the JWT validator record.

The auth_jwt_demo module provides examples.

The JWT validator can be configured with the following properties:

• name: the validator name, to match the auth="jwt_{validator-name}" route property.
• audience: a comma-separated list of allowed audiences, used to validate the aud claim.
• issuer: used to validate the iss claim.
• Signature type (secret or public key), algorithm, secret and JWK URI are used to validate the token signature.

In addition, the exp claim is validated to reject expired tokens.

If the Authorization HTTP header is missing, malformed, or contains an invalid token, the request is rejected with a 401 (Unauthorized) code, unless the cookie mode is enabled (see below).

If the token is valid, the request executes with the configured user id. By default the user id selection strategy is static (i.e. the same for all requests) and the selected user is configured on the JWT validator. Additional strategies can be provided by overriding the _get_uid() method and extending the user_id_strategy selection field.

The selected user is not stored in the session. It is only available in request.uid (and thus it is the one used in request.env). To avoid any confusion and mismatches between the bearer token and the session, this module rejects requests made with an authenticated user session.

Additionally, if a partner_id_strategy is configured, a partner is searched and if found, its id is stored in the request.jwt_partner_id attribute. If partner_id_required is set, a 401 (Unauthorized) is returned if no partner was found. Otherwise request.jwt_partner_id is left falsy. Additional strategies can be provided by overriding the _get_partner_id() method and extending the partner_id_strategy selection field.

The decoded JWT payload is stored in request.jwt_payload.

The public_auth_jwt method delegates authentication to the standard Odoo public method when the Authorization header is not set. If it is set, the regular JWT authentication is performed as described above. This method is useful for public endpoints that need to work for anonymous users, but can be enhanced when an authenticated user is know. A typical use case is a "add to cart" endpoint that can work for anonymous users, but can be enhanced by binding the cart to a known customer when the authenticated user is known.

You can enable a cookie mode on JWT validators. In this case, the JWT payload obtained from the Authorization header is returned as a Http-Only cookie. This mode is sometimes simpler for front-end applications which do not then need to store and protect the JWT token across requests and can simply rely on the cookie management mechanisms of browsers. When both the Authorization header and a cookie are provided, the cookie is ignored in order to let clients authenticate with a different user by providing a new JWT token.
