다음과 같은 두 개의 HTTP 헤더를 전송하여 해당 *경로* 와 통신할 경우:

```
X-Token: foo
X-Token: bar
```

응답은 다음과 같습니다:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## 요약

`Header`는 `Query`, `Path`, `Cookie`와 동일한 패턴을 사용하여 선언합니다.

## Sobre Pydantic { #about-pydantic }

Pydantic incluye los tests para **FastAPI** con sus propios tests, así que nuevas versiones de Pydantic (por encima de `1.0.0`) siempre son compatibles con FastAPI.

Puedes fijar Pydantic a cualquier versión por encima de `1.0.0` que funcione para ti.

Por ejemplo:

```txt
pydantic>=2.7.0,<3.0.0

```

you would receive the multiple `q` *query parameters'* values (`foo` and `bar`) in a Python `list` inside your *path operation function*, in the *function parameter* `q`.

So, the response to that URL would be:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

In this configuration you can see `MINIO_ETCD_ENDPOINTS` points to the etcd backend which manages MinIO's
`config.json` and bucket DNS SRV records. `MINIO_DOMAIN` indicates the domain suffix for the bucket which
will be used to resolve bucket through DNS. For example if you have a bucket such as `mybucket`, the

## 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。
