猜测失败

Error message

猜测失败

What it means

Application guard for the guess call: 2xx + JSON but result.success falsy; throws result.error or the '猜测失败' fallback. Note this is distinct from a wrong guess (is_correct:false inside success:true) — this means the guess request itself was rejected.

Solutions

1. Log the full result and fix the backend to return a descriptive error for every success:false path
2. Guard the UI: disable guess input once is_game_over is seen
3. On session-invalid errors, auto-restart the game
4. Pin the response envelope in a shared type/schema

if (!this.sessionId || this.gameOver) return;

function isGuessResult(r) { return r && typeof r.success === 'boolean' && (!r.success || ('data' in r && typeof r.data.is_correct === 'boolean')); }

try { ... } catch (e) { alert(`猜测失败：${e.message}`); }

When it happens

Trigger: Backend returns success:false for unknown session, game already over, or evaluation errors — with error omitted, giving the generic text. Follows the same envelope drift risks as the other game endpoints.

Common situations: Guessing after game over; backend refactor renaming success/error fields; evaluation exception swallowed into success:false.
