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

{* ../../docs_src/async_tests/app_a_py39/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.

# 並行処理と async / await

*path operation 関数*のための `async def` に関する詳細と非同期 (asynchronous) コード、並行処理 (Concurrency)、そして、並列処理 (Parallelism) の背景について。

## 急いでいますか？

<abbr title="too long; didn't read (長すぎて読めない人のための要約という意味のスラング)"><strong>TL;DR:</strong></abbr>

次のような、`await` を使用して呼び出すべきサードパーティライブラリを使用している場合:

```Python
results = await some_library()
```

以下の様に `async def` を使用して*path operation 関数*を宣言します。

```Python hl_lines="2"
@app.get('/')

**FastAPI** provides the same `WebSocket` directly just as a convenience for you, the developer. But it comes directly from Starlette.

///

## Await for messages and send messages { #await-for-messages-and-send-messages }

In your WebSocket route you can `await` for messages and send messages.

{* ../../docs_src/websockets/tutorial001_py39.py hl[48:52] *}

You can receive and send binary, text, and JSON data.

///

## Aguarde mensagens e envie mensagens { #await-for-messages-and-send-messages }

Em sua rota WebSocket você pode esperar (`await`) por mensagens e enviar mensagens.

{* ../../docs_src/websockets/tutorial001_py39.py hl[48:52] *}

Você pode receber e enviar dados binários, de texto e JSON.

            return await func(*args, **kwargs)
        if inspect.isclass(func):
            return await run_in_threadpool(func, *args, **kwargs)
        dunder_call = getattr(func, "__call__", None)  # noqa: B004
        if iscoroutinefunction(dunder_call):
            return await dunder_call(*args, **kwargs)
        return await run_in_threadpool(func, *args, **kwargs)

    return wrapper

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

{* ../../docs_src/async_tests/app_a_py39/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.

* `seek(offset)`: Перейти к байту на позиции `offset` (`int`) в файле.
    * Например, `await myfile.seek(0)` перейдет к началу файла.
    * Это особенно удобно, если вы один раз выполнили команду `await myfile.read()`, а затем вам нужно прочитать содержимое файла еще раз.
* `close()`: Закрыть файл.

Поскольку все эти методы являются `async` методами, вам следует использовать "await" вместе с ними.
