Il effectue également la validation des données (même imbriquées les unes dans les autres), et permet de les documenter correctement (schéma OpenAPI et documentation auto-générée).

## 调研

通过使用之前所有的备选方案，我有机会从它们之中学到了很多东西，获取了很多想法，并以我和我的开发团队能想到的最好方式把这些思路整合成一体。

例如，大家都清楚，在理想状态下，它应该基于标准的 Python 类型提示。

而且，最好的方式是使用现有的标准。

因此，甚至在开发 **FastAPI** 前，我就花了几个月的时间研究 OpenAPI、JSON Schema、OAuth2 等规范。深入理解它们之间的关系、重叠及区别之处。

## 设计

然后，我又花了一些时间从用户角度（使用 FastAPI 的开发者）设计了开发者 **API**。

同时，我还在最流行的 Python 代码编辑器中测试了很多思路，包括 PyCharm、VS Code、基于 Jedi 的编辑器。

	lcfg, err := latest.Scheme.ConvertToVersion(kcfg, latest.ExternalVersion)
	if err != nil {
		return kubeconfig{}, err
	}
	// Convert to v1 schema which has proper encoding
	fullYaml, err := yaml.Marshal(lcfg)
	if err != nil {
		return kubeconfig{}, err
	}

	// Log with redaction
	if err := api.RedactSecrets(kcfg); err != nil {

Тогда, подразумеваются атрибуты JSON, их типы данных и т.п.

#### OpenAPI и JSON Schema

OpenAPI описывает схему API. Эта схема содержит определения (или "схемы") данных, отправляемых и получаемых API. Для описания структуры данных в JSON используется стандарт **JSON Schema**.

#### Рассмотрим `openapi.json`

## OpenAPI and API docs

If you return additional status codes and responses directly, they won't be included in the OpenAPI schema (the API docs), because FastAPI doesn't have a way to know beforehand what you are going to return.
