Lo que suele suponerse
Rack::Protection::AuthenticityToken.token returns a static raw session token, and any token generated for a session validates any state-changing POST endpoint.
El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.
Contrato
- `Rack::Protection::AuthenticityToken.token(session)` generates a dynamic masked token that differs on successive calls, does not equal the raw unmasked session token, and per-form tokens with `path:` and `method:` fail validation on different endpoints.
- Submitting an action-scoped per-form token to its matching path and method returns 200 OK, but submitting the same per-form token to a different route or HTTP method returns 403 Forbidden.
- Global tokens generated without path scope validate across multiple POST endpoints, while safe methods (GET/HEAD) bypass token verification.
