常见的想当然
AuthenticityToken passes safe GET requests through to downstream handlers without requiring an active session store.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- AuthenticityToken responds with 403 Forbidden on safe GET requests when env lacks rack.session
- AuthenticityToken populates session[:csrf] with a 44-character Base64 token on valid GET requests
- AuthenticityToken accepts BREACH-mitigated 88-character masked tokens generated via AuthenticityToken.token
- AuthenticityToken accepts raw unmasked tokens matching session[:csrf] over HTTP_X_CSRF_TOKEN
- AuthenticityToken rejects unsafe POST requests with invalid tokens with 403 Forbidden and text/plain body
- AuthenticityToken restricts path-scoped per-form tokens strictly to matching request paths
