- QueueingHint got error in its returning value. If QueueingHint returns error, the scheduler logs the error and treats the event as QueueAfterBackoff so that the Pod wouldn't be stuck in the unschedulable pod pool.

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:

   *
   * If the response body was successfully read until the end, this is the headers that followed,
   * or empty headers if there were none that followed.
   *
   * If the response body was closed prematurely or failed with an error, this will be the sentinel
   * value [TRAILERS_RESPONSE_BODY_TRUNCATED]. In that case attempts to read the trailers should not
   * return the value but instead throw an exception.
