* Si on n'utilisait pas FastAPI mais directement Starlette (ou un outil équivalent comme Sanic, Flask, Responder, etc) il faudrait implémenter la validation des données et la sérialisation par nous-même. Le résultat serait donc le même dans les deux cas mais du travail supplémentaire serait à réaliser avec Starlette, surtout en considérant que la validation...

  TF_DeviceList* response = new TF_DeviceList;
  if (session && session->session)
    status->status = session->session->ListDevices(&response->response);
  return response;
}

TF_DeviceList* TF_DeprecatedSessionListDevices(TF_DeprecatedSession* session,
                                               TF_Status* status) {
  TF_DeviceList* response = new TF_DeviceList;
  if (session && session->session)

///

Dann können wir einen `AsyncClient` mit der App erstellen und mit `await` asynchrone Requests an ihn senden.

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

Das ist das Äquivalent zu:

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

... welches wir verwendet haben, um unsere Requests mit dem `TestClient` zu machen.

/// tip | "Tipp"

///

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.

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

This is the equivalent to:

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

...that we used to make our requests with the `TestClient`.

/// tip

Note that we're using async/await with the new `AsyncClient` - the request is asynchronous.

///

```

/// info | "说明"

注意，`response_description` 只用于描述响应，`description` 一般则用于描述*路径操作*。

///

/// check | "检查"

OpenAPI 规定每个*路径操作*都要有响应描述。

如果没有定义响应描述，**FastAPI** 则自动生成内容为 "Successful response" 的响应描述。

## 弃用*路径操作*

`deprecated` 参数可以把*路径操作*标记为<abbr title="过时，建议不要使用">弃用</abbr>，无需直接删除：
