そして、チュートリアルと同様な方法でアプリケーションを起動して下さい。ただし、以下の様に`--reload` オプションは使用しないで下さい:

//// tab | Uvicorn

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

<span style="color: green;">INFO</span>:     Uvicorn running on http://0.0.0.0:80 (Press CTRL+C to quit)
```

</div>

//// tab | Hypercorn

<div class="termy">

```console
$ hypercorn main:app --bind 0.0.0.0:80

그런 뒤, 우리는 `FastAPI` 앱을 만들 때 그것을 사용합니다.

환경 변수 `OPENAPI_URL`을 빈 문자열로 설정하여 OpenAPI(문서 UI 포함)를 비활성화할 수도 있습니다. 예를 들어:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

그리고 `/openapi.json`, `/docs` 또는 `/redoc`의 URL로 이동하면 `404 Not Found`라는 오류가 다음과 같이 표시됩니다:

```JSON

/**
 * Service for creating {@link PathMatcher} objects that can be used to filter files
 * based on include/exclude patterns. This service provides a clean API for plugins
 * to create path matchers without directly depending on implementation classes.
 * <p>

For those cases, you can use a `Response` parameter.

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies and headers).

And then you can set the `status_code` in that *temporal* response object.

When defining WebSockets, you normally declare a parameter of type `WebSocket` and with it you can read data from the client and send data to it.

It is provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi import WebSocket
```

/// tip

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,

## Recap { #recap }

You can add multiple body parameters to your *path operation function*, even though a request can only have a single body.

But **FastAPI** will handle it, give you the correct data in your function, and validate and document the correct schema in the *path operation*.

You can also declare singular values to be received as part of the body.
