实际上，HTTP `PUT` 也可以使用同样的技巧。

但这里用 `PATCH` 举例，因为它就是为这种用例设计的。

/// note | 注意

注意，输入模型仍会被验证。

因此，如果希望接收的部分更新可以省略所有属性，则需要一个所有属性都标记为可选（带默认值或 `None`）的模型。

为了区分用于**更新**（全部可选）和用于**创建**（必填）的模型，可以参考[更多模型](extra-models.md) 中介绍的思路。

Additional optional Pydantic dependencies:

* [`pydantic-settings`](https://docs.pydantic.dev/latest/usage/pydantic_settings/) - for settings management.
* [`pydantic-extra-types`](https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/) - for extra types to be used with Pydantic.

Additional optional FastAPI dependencies:

* [`orjson`](https://github.com/ijl/orjson) - Required if you want to use `ORJSONResponse`.

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

**FastAPI** will use that *temporal* response to extract the headers (also cookies and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

Si integras tu API con un proveedor OAuth2, podrás autenticarte y regresar a la documentación de la API con las credenciales adquiridas. E interactuar con ella usando la autenticación real de OAuth2.

Swagger UI lo manejará detrás de escena para ti, pero necesita este auxiliar de "redirección".
