## 等待消息并发送消息

在您的 WebSocket 路由中，您可以使用 `await` 等待消息并发送消息。

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

您可以接收和发送二进制、文本和 JSON 数据。

## 尝试一下

如果您的文件名为 `main.py`，请使用以下命令运行应用程序：

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

            index = (index + 1) % children.length
        }
        announceRandom()
        setInterval(announceRandom, timeInterval
        )
    }
}

async function main() {
    if (div) {
        data = await getData()
        div.innerHTML = '<ul></ul>'
        const ul = document.querySelector('.github-topic-projects ul')
        data.forEach(v => {

<summary>О команде <code>uvicorn main:app --reload</code>...</summary>

Команда `uvicorn main:app` относится к:

* `main`: файл `main.py` (модуль Python).
* `app`: объект, созданный внутри `main.py` с помощью строки `app = FastAPI()`.
* `--reload`: перезапуск сервера после изменения кода. Делайте это только во время разработки.

</details>
