Root Cause

The token type hint parameter in the token revocation or introspection request is not recognized by the authorization server, often due to a typo or unsupported value.

令牌撤销或内省请求中的令牌类型提示参数未被授权服务器识别，通常由于拼写错误或不支持的值。

Workarounds

  1. 90% success Ensure the token_type_hint parameter uses one of the standard values: 'access_token' or 'refresh_token'. Example: `POST /revoke HTTP/1.1\nContent-Type: application/x-www-form-urlencoded\ntoken=abc123&token_type_hint=access_token`.

  2. 85% success Check the authorization server's documentation for supported token type hints. For Keycloak, also try 'id_token' if using OpenID Connect.

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Some servers require the hint for revocation; without it, the request may fail or return an error.

  2. 80% fail

    The server only recognizes standard token type hints; custom values are rejected.

  3. 70% fail

    OAuth2 token revocation endpoints typically expect application/x-www-form-urlencoded format, not JSON.
