 2. It attempts to retrieve a connection with that address from the **connection pool**.
 3. If it doesn't find a connection in the pool, it selects a **route** to attempt. This usually means making a DNS request to get the server's IP addresses. It then selects a TLS version and proxy server if necessary.

그 다음에  `AsyncClient` 로 앱을 만들고 비동기 요청을 `await` 키워드로 보낼 수 있습니다:

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

위의 코드는:

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

`TestClient` 에 요청을 보내던 것과 동일합니다.

새로운 `AsyncClient`를 사용할 때 async/await를 사용하고 있다는 점에 주목하세요. 이 요청은 비동기적으로 처리됩니다.

Let's say that now the file `main.py` with your **FastAPI** app has some other **path operations**.

It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

```

Припустимо, що тепер файл `main.py` із Вашим **FastAPI**-застосунком містить додаткові операції шляху (**path operations**).

Він має `GET`-операцію, яка може повертати помилку.

Він має `POST`-операцію, яка може повертати кілька помилок.

Обидві операції шляху вимагають заголовок `X-Token`.
