### Create the `Settings` object { #create-the-settings-object }

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

    post_content = content[post_start:]
    new_content = pre_content + message + post_content
    # Remove content between <!-- only-mkdocs --> and <!-- /only-mkdocs -->
    new_content = re.sub(
        r"<!-- only-mkdocs -->.*?<!-- /only-mkdocs -->",
        "",
        new_content,
        flags=re.DOTALL,
    )
    return new_content

如果不想让 **FastAPI** 包含使用 `root_path` 的自动服务器，则要使用参数 `root_path_in_servers=False`：

{* ../../docs_src/behind_a_proxy/tutorial004.py hl[9] *}

这样，就不会在 OpenAPI 概图中包含服务器了。

## 挂载子应用

如需挂载子应用（详见 [子应用 - 挂载](sub-applications.md){.internal-link target=_blank}），也要通过 `root_path` 使用代理，这与正常应用一样，别无二致。
