All Superinterfaces:

Lifecycle

@ThreadSafe
public interface PARValidator
extends Lifecycle

Service Provider Interface (SPI) for performing additional validation of Pushed Authorisation Requests (PAR).

The validatePushedAuthorizationRequest(com.nimbusds.oauth2.sdk.AuthorizationRequest, com.nimbusds.openid.connect.provider.spi.par.ValidatorContext) method will be called after the Connect2id server has performed standard validation of the OAuth 2.0 authorisation / OpenID authentication request, such as checking the client_id and ensuring the client is authorised to use the OAuth 2.0 grant. JWT-secured authorisation requests (JAR) will be unwrapped / resolved before that. The original raw request can be obtained from the context.

The validated request can be returned modified. Modifications should be limited to optional parameters. Parameters such as client_id, response_type, redirect_uri and state must not be modified.

The validatePushedAuthorizationRequest(com.nimbusds.oauth2.sdk.AuthorizationRequest, com.nimbusds.openid.connect.provider.spi.par.ValidatorContext) method can reject the request by throwing an InvalidPushedAuthorizationRequestException with an appropriate HTTP status code and error code. The exception message will be logged and not output to the client.

Example:

 throw new InvalidPARException("Scope not accepted scope", // will be logged
        OAuth2Error.INVALID_SCOPE
        .setHTTPStatusCode(400)
        .setDescription("Scope not accepted: some_scope"));
 

The resulting HTTP response:

 HTTP/1.1 400 Bad Request
 Content-Type: application/json;charset=UTF-8
 Cache-Control: no-store
 Pragma: no-cache

 {
   "error"             : "invalid_scope",
   "error_description" : "Scope not accepted: some_scope"
 }
 

Implementations must be thread-safe.
