Function HashBody

internal/idempotency/store.go:106–109

HashBody returns the sha256 hex of the raw request body. Exposed so callers (the HTTP layer) can compute it once from the bytes they already read, rather than re-reading or re-encoding.

(body []byte)

// callers (the HTTP layer) can compute it once from the bytes they
// already read, rather than re-reading or re-encoding.
func HashBody(body []byte) string {
	sum := sha256.Sum256(body)
	return hex.EncodeToString(sum[:])
}

// HashRequest mixes the request path into the body hash so the same
// Idempotency-Key cannot accidentally replay a cached response across
