你还可以返回 Pydantic 模型（稍后你将了解更多）。

还有许多其他将会自动转换为 JSON 的对象和模型（包括 ORM 对象等）。尝试下使用你最喜欢的一种，它很有可能已经被支持。

## 总结

* 导入 `FastAPI`。
* 创建一个 `app` 实例。
* 编写一个**路径操作装饰器**（如 `@app.get("/")`）。
* 编写一个**路径操作函数**（如上面的 `def root(): ...`）。

## Підіб'ємо підсумки

* Імпортуємо `FastAPI`.
* Створюємо екземпляр `app`.
* Пишемо **декоратор операції шляху** як `@app.get("/")`.
* Пишемо **функцію операції шляху**; наприклад, `def root(): ...`.

* Trusty: Regional release .tar.gz support ([#23558](https://github.com/kubernetes/kubernetes/pull/23558), [@andyzheng0831](https://github.com/andyzheng0831))
* Make ConfigMap volume readable as non-root ([#23793](https://github.com/kubernetes/kubernetes/pull/23793), [@pmorie](https://github.com/pmorie))

4)  Derive a new KEK from the new data key and re-encrypt the OEK with it.
5)  Store the encrypted OEK encrypted data key and master key ID in object metadata.
