But it was created before there existed Python type hints. So, to define every <abbr title="the definition of how data should be formed">schema</abbr> you need to use specific utils and classes provided by Marshmallow.

!!! check "Inspired **FastAPI** to"
    Use code to define "schemas" that provide data types and validation, automatically.

作为应用对象创建的组成部分，要注册 `/openapi.json` （或其它为 `openapi_url` 设置的任意内容）*路径操作*。

它只返回包含应用的 `.openapi()` 方法操作结果的 JSON 响应。

但默认情况下，`.openapi()` 只是检查 `.openapi_schema` 属性是否包含内容，并返回其中的内容。

如果 `.openapi_schema` 属性没有内容，该方法就使用 `fastapi.openapi.utils.get_openapi` 工具函数生成内容。

`get_openapi()` 函数接收如下参数：

* `title`：文档中显示的 OpenAPI 标题
* `version`：API 的版本号，例如 `2.5.0`
* `openapi_version`： OpenAPI 规范的版本号，默认为最新版： `3.0.2`
* `description`：API 的描述说明
