## Aguardar por mensagens e enviar mensagens

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

{*../../docs_src/websockets/tutorial001.py hl[48:52]*}

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

## Tente você mesmo

/// tip | 팁

테스트 함수가 이제 `TestClient`를 사용할 때처럼 단순히 `def`가 아니라 `async def`로 작성된 점에 주목해주세요.

///

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.
