/**
* Authorisation error response. Intended only for errors which are allowed to
* be communicated back to the requesting OAuth 2.0 client, such as
* {@code access_denied}. For a complete list see OAuth 2.0 (RFC 6749),
* sections 4.1.2.1 and 4.2.2.1.
*
* If the authorisation request fails due to a missing, invalid, or
* mismatching {@code redirect_uri}, or if the {@code client_id} is missing or
* invalid, a response must not be sent back to the requesting
* client. Instead, the authorisation server should simply display the error
* to the resource owner.
*
*
Standard authorisation errors:
*
*
* - {@link OAuth2Error#INVALID_REQUEST}
*
- {@link OAuth2Error#UNAUTHORIZED_CLIENT}
*
- {@link OAuth2Error#ACCESS_DENIED}
*
- {@link OAuth2Error#UNSUPPORTED_RESPONSE_TYPE}
*
- {@link OAuth2Error#INVALID_SCOPE}
*
- {@link OAuth2Error#SERVER_ERROR}
*
- {@link OAuth2Error#TEMPORARILY_UNAVAILABLE}
*
*
* Example HTTP response:
*
*
* HTTP/1.1 302 Found
* Location: https://client.example.com/cb?
* error=invalid_request
* &error_description=the%20request%20is%20not%20valid%20or%20malformed
* &state=af0ifjsldkj
*
*
* Related specifications:
*
*
* - OAuth 2.0 (RFC 6749), sections 4.1.2.1 and 4.2.2.1.
*
- OAuth 2.0 Multiple Response Type Encoding Practices 1.0.
*
- OAuth 2.0 Form Post Response Mode 1.0.
*
- Financial-grade API: JWT Secured Authorization Response Mode for
* OAuth 2.0 (JARM).
