このため、**FastAPI**自体が代替のAPIドキュメントを提供します（ReDocを使用）。これは、 <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a> にアクセスすると確認できます。

同様に、互換性のあるツールが多数あります（多くの言語用のコード生成ツールを含む）。

## Pydantic

```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>

すると、以下のように `/openapi.json`, `/docs`, `/redoc` のどのURLにアクセスしても、 `404 Not Found` エラーが返ってくるようになります。

```JSON
{
    "detail": "Not Found"
}

또한 여러분은 <a href="http://192.168.99.100/redoc" class="external-link" target="_blank">http://192.168.99.100/redoc</a> 또는 <a href="http://127.0.0.1/redoc" class="external-link" target="_blank">http://127.0.0.1/redoc</a>으로 이동할 수 있습니다(또는, 여러분의 도커 호스트를 이용할 수 있습니다).

여러분은 자동으로 생성된 대안 문서(<a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>에서 제공된)를 볼 수 있습니다:

    assert "window.opener.swaggerUIRedirectOauth2" in response.text


def test_redoc():
    response = client.get("/redoc")
    assert response.status_code == 200, response.text
    assert response.headers["content-type"] == "text/html; charset=utf-8"
    assert "redoc@2" in response.text


def test_enum_status_code_response():
    response = client.get("/enum-status-code")

## 代替のAPIドキュメント

また、<a href="http://192.168.99.100/redoc" class="external-link" target="_blank">http://192.168.99.100/redoc</a> や <a href="http://127.0.0.1/redoc" class="external-link" target="_blank">http://127.0.0.1/redoc</a> (またはそれに相当するDockerホストを使用したもの）にもアクセスできます。

代替の自動ドキュメント（<a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>によって提供される）が表示されます：

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>
* <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>

Эти два инструмента выбраны за популярность и стабильность, но даже при беглом поиске можно найти десятки альтернативных интерфейсов для OpenAPI (которые можно использовать с **FastAPI**).

Ayrıca standarda bağlı kullanıcı arayüzü araçlarını entegre etmeli:

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>
* <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>

Yukarıdaki ikisi oldukça popüler ve istikrarlı olduğu için seçildi, ancak hızlı bir araştırma yaparak **FastAPI** ile kullanabileceğiniz pek çok OpenAPI alternatifi arayüz bulabilirsiniz.

Und Standard-basierte Tools für die Oberfläche zu integrieren:

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>
* <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>

 * <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Інтерфейс Swagger</a>
 * <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>

And integrate standards-based user interface tools:

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>
* <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>

These two were chosen for being fairly popular and stable, but doing a quick search, you could find dozens of alternative user interfaces for OpenAPI (that you can use with **FastAPI**).
