## Disable Syntax Highlighting

For example, you could disable syntax highlighting in Swagger UI.

Without changing the settings, syntax highlighting is enabled by default:

<img src="/img/tutorial/extending-openapi/image02.png">

But you can disable it by setting `syntaxHighlight` to `False`:

```Python hl_lines="3"

This could be useful if for example you live in a country that restricts some URLs.

### Disable the automatic docs

The first step is to disable the automatic docs, as by default, those use the default CDN.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

```Python hl_lines="8"
{!../../../docs_src/custom_docs_ui/tutorial001.py!}
```

    from docs_src.conditional_openapi import tutorial001

    importlib.reload(tutorial001)

    client = TestClient(tutorial001.app)
    return client


@needs_pydanticv2
def test_disable_openapi(monkeypatch):
    monkeypatch.setenv("OPENAPI_URL", "")
    # Load the client after setting the env var
    client = get_client()
    response = client.get("/openapi.json")

文档显示如下：

## 启用公开访问

默认情况下，Deta 使用您的账号 Cookies 处理身份验证。

应用一切就绪之后，使用如下命令让公众也能看到您的应用：

<div class="termy">

```console
$ deta auth disable

Successfully disabled http auth
```

</div>

现在，就可以把 URL 分享给大家，他们就能访问您的 API 了。🚀

## HTTPS

恭喜！您已经在 Deta 上部署了 FastAPI 应用！🎉 🍰

So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.

If for some reason you need to disable automatic conversion of underscores to hyphens, set the parameter `convert_underscores` of `Header` to `False`:

=== "Python 3.10+"

    ```Python hl_lines="10"

In that case, you can disable this feature in **FastAPI**, with the parameter `separate_input_output_schemas=False`.

!!! info
    Support for `separate_input_output_schemas` was added in FastAPI `0.102.0`. 🤓
