그 다음 앱으로 `AsyncClient`를 만들고, `await`를 사용해 비동기 요청을 보낼 수 있습니다.

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[9:12] *}

이는 다음과 동등합니다:

```Python
response = client.get('/')
```

`TestClient`로 요청을 보내기 위해 사용하던 코드입니다.

/// tip | 팁

새 `AsyncClient`와 함께 async/await를 사용하고 있다는 점에 주목하세요. 요청은 비동기입니다.

그래서 여전히 Pydantic 모델을 사용해야 할 수도 있습니다.

하지만 이미 여러 dataclasses를 가지고 있다면, 이것은 FastAPI로 웹 API를 구동하는 데 그것들을 활용할 수 있는 좋은 방법입니다. 🤓

///

## `response_model`에서 Dataclasses 사용하기 { #dataclasses-in-response-model }

`response_model` 매개변수에서도 `dataclasses`를 사용할 수 있습니다:

{* ../../docs_src/dataclasses_/tutorial002_py310.py hl[1,6:12,18] *}

dataclass는 자동으로 Pydantic dataclass로 변환됩니다.

你也可以在 `APIRouter` 上設定 `route_class` 參數：

{* ../../docs_src/custom_request_and_route/tutorial003_py310.py hl[26] *}

在此範例中，`router` 底下的路徑操作會使用自訂的 `TimedRoute` 類別，並在回應中多加上一個 `X-Response-Time` 標頭，標示產生該回應所花費的時間：

  // Backing memory for missing_unused_key_names values.
  std::vector<std::string> missing_unused_key_names_data;
};

struct TF_DeviceList {
  std::vector<tensorflow::DeviceAttributes> response;
};

struct TF_Function {
  tensorflow::FunctionRecord* record;
};

struct TF_ApiDefMap {
  explicit TF_ApiDefMap(const tensorflow::OpList& op_list)
      :

                         ← UrlQueueService ← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ←
                         ← DataService ← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ←
```

- **Rule**: Pattern-based response routing (`RegexRule`, `SitemapsRule`)
- **ResponseProcessor**: `DefaultResponseProcessor`, `SitemapsResponseProcessor`, `NullResponseProcessor`
- **Transformer**: `HtmlTransformer`, `XmlTransformer`, `FileTransformer`, etc.

suggester.removeDisableIndices();       // Cleanup old indices
```

**Async Operations:**
```java
suggester.suggest()
    .setQuery("search")
    .execute()
    .done(response -> { /* handle success */ })
    .error(throwable -> { /* handle error */ });
```

## Important Notes

### Thread Safety
- **Suggester**: Thread-safe for queries

   * a response from a remote station. It may be used as a "Who Are You" (WRU) to obtain
   * identification, or may be used to obtain station status, or both.
   *
   * @since 8.0
   */
  public static final byte ENQ = 5;

  /**
   * Acknowledge: A communication control character transmitted by a receiver as an affirmative
   * response to a sender.
   *
   * @since 8.0
   */

... alors, comme `description` a une valeur par défaut, si vous ne retournez rien pour ce champ, il aura tout de même cette **valeur par défaut**.

### Modèle pour les données de réponse en sortie { #model-for-output-response-data }

Si vous interagissez avec les documents et vérifiez la réponse, même si le code n'a rien ajouté dans l'un des champs `description`, la réponse JSON contient la valeur par défaut (`null`) :
