它接收一个对象，比如Pydantic模型，并会返回一个JSON兼容的版本：

{* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}

在这个例子中，它将Pydantic模型转换为`dict`，并将`datetime`转换为`str`。

调用它的结果后就可以使用Python标准编码中的[`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)。

这个操作不会返回一个包含JSON格式（作为字符串）数据的庞大的`str`。它将返回一个Python标准数据结构（例如`dict`），其值和子值都与JSON兼容。

/// note | 注意

`jsonable_encoder`实际上是**FastAPI**内部用来转换数据的。但是它在许多其他场景中也很有用。

## Prerequisites

To get started with MinIO, refer [MinIO QuickStart Document](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html).
Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

[Download the latest release](https://prometheus.io/download) of Prometheus for your platform, then extract it

La manera en que los formularios HTML (`<form></form>`) envían los datos al servidor normalmente usa una codificación "especial" para esos datos, es diferente de JSON.

**FastAPI** se encargará de leer esos datos del lugar correcto en lugar de JSON.

이 예시에서는 Pydantic 모델을 `dict`로, `datetime`을 `str`로 변환합니다.

이렇게 호출한 결과는 파이썬 표준인 [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)로 인코딩할 수 있습니다.

JSON 형식(문자열)의 데이터가 들어있는 큰 `str`을 반환하지 않습니다. JSON과 모두 호환되는 값과 하위 값이 있는 파이썬 표준 데이터 구조(예: `dict`)를 반환합니다.
