Deploy etmeden önce giriş yaptığınızdan emin olun:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Ardından uygulamanızı deploy edin:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

檔案 `test_main.py` 會包含針對 `main.py` 的測試，現在可能像這樣：

{* ../../docs_src/async_tests/app_a_py310/test_main.py *}

## 執行 { #run-it }

如常執行測試：

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## 詳解 { #in-detail }

標記 `@pytest.mark.anyio` 告訴 pytest 這個測試函式應以非同步方式執行：

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip

{* ../../docs_src/json_base64_bytes/tutorial001_py310.py ln[1:9,29:35] hl[9] *}

「/docs」を確認すると、`data` フィールドが base64 でエンコードされたバイト列を期待していることが表示されます。

<div class="screenshot">

</div>

次のようなリクエストを送れます:

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// tip | 豆知識

`aGVsbG8=` は `hello` の base64 エンコードです。

Antes de desplegar, asegúrate de haber iniciado sesión:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Luego despliega tu app:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

Avant de déployer, vous devez vous assurer que vous êtes connecté :

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Puis déployez votre application :

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

Antes do deploy, certifique-se de que está autenticado:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Em seguida, faça o deploy da sua aplicação:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

首先，确保你创建并激活了[虚拟环境](../virtual-environments.md)，然后安装 `pydantic-settings` 包：

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

当你用以下方式安装 `all` 扩展时，它也会被一并安装：

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

### 创建 `Settings` 对象 { #create-the-settings-object }

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Application startup complete.
```

</div>

//// tab | `uvicorn`

If you prefer to use the `uvicorn` command directly:

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 8080 --workers 4

**FastAPI**는 요청에서 받은 **헤더**에서 **각 필드**에 대한 데이터를 **추출**하고 정의한 Pydantic 모델을 줍니다.

## 문서 확인하기 { #check-the-docs }

문서 UI `/docs`에서 필요한 헤더를 볼 수 있습니다:

<div class="screenshot">
<img src="/img/tutorial/header-param-models/image01.png">
</div>

## 추가 헤더 금지하기 { #forbid-extra-headers }

일부 특별한 사용 사례(흔하지는 않겠지만)에서는 수신하려는 헤더를 **제한**할 수 있습니다.

Pydantic의 모델 구성을 사용하여 추가(`extra`) 필드를 금지(`forbid`)할 수 있습니다:

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<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>

Then if you go to the URLs at `/openapi.json`, `/docs`, or `/redoc` you will just get a `404 Not Found` error like:
