# JSON互換エンコーダ

データ型（Pydanticモデルのような）をJSONと互換性のあるもの（`dict`や`list`など）に変更する必要がある場合があります。

例えば、データベースに保存する必要がある場合です。

そのために、**FastAPI** は`jsonable_encoder()`関数を提供しています。

## `jsonable_encoder`の使用

JSON互換のデータのみを受信するデータベース`fase_db`があるとしましょう。

例えば、`datetime`オブジェクトはJSONと互換性がないので、このデーターベースには受け取られません。

そのため、`datetime`オブジェクトは<a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO形式</a>のデータを含む`str`に変換されなければなりません。

Further any secret key (apart from the KMS-generated ones) is 256 bits long. The KMS-generated keys may be 256 bits but this depends on the KMS capabilities and configuration.

		// KMS Key APIs
		kmsRouter.Methods(http.MethodPost).Path(version+"/key/create").HandlerFunc(gz(httpTraceAll(kmsAPI.KMSCreateKeyHandler))).Queries("key-id", "{key-id:.*}")
		kmsRouter.Methods(http.MethodGet).Path(version+"/key/list").HandlerFunc(gz(httpTraceAll(kmsAPI.KMSListKeysHandler))).Queries("pattern", "{pattern:.*}")
		kmsRouter.Methods(http.MethodGet).Path(version + "/key/status").HandlerFunc(gz(httpTraceAll(kmsAPI.KMSKeyStatusHandler)))
	}

# JSON 兼容编码器

在某些情况下，您可能需要将数据类型（如Pydantic模型）转换为与JSON兼容的数据类型（如`dict`、`list`等）。

比如，如果您需要将其存储在数据库中。

对于这种要求， **FastAPI**提供了`jsonable_encoder()`函数。

## 使用`jsonable_encoder`

让我们假设你有一个数据库名为`fake_db`，它只能接收与JSON兼容的数据。

例如，它不接收`datetime`这类的对象，因为这些对象与JSON不兼容。

因此，`datetime`对象必须将转换为包含<a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO格式化</a>的`str`类型对象。

同样，这个数据库也不会接收Pydantic模型（带有属性的对象），而只接收`dict`。
