要するに、`stanleyjobsox` と `stanleyjobson` を比較するのにかかる時間は、`johndoe` と `stanleyjobson` を比較するのにかかる時間と同じになります。パスワードでも同様です。

このように、アプリケーションコードで `secrets.compare_digest()` を使うと、この種の一連のセキュリティ攻撃に対して安全になります。

### エラーを返す { #return-the-error }

認証情報が不正であることを検出したら、ステータスコード 401（認証情報が提供されない場合と同じ）で `HTTPException` を返し、ブラウザに再度ログインプロンプトを表示させるためにヘッダー `WWW-Authenticate` を追加します:

### 背景任務與含有 `yield` 的相依，技術細節 { #background-tasks-and-dependencies-with-yield-technical-details }

在 FastAPI 0.106.0 之前，不可能在 `yield` 之後拋出例外；含有 `yield` 的相依的結束程式碼會在回應送出之後才執行，因此[例外處理器](../tutorial/handling-errors.md#install-custom-exception-handlers) 早就已經跑完了。

當初這樣設計主要是為了允許在背景任務中使用由相依「yield」出來的同一組物件，因為結束程式碼會在背景任務結束後才執行。

在 FastAPI 0.106.0 中，這個行為被修改，目的是在等待回應穿越網路的期間，不要持有資源。
