## `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`fake_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。

同様に、このデータベースはPydanticモデル（属性を持つオブジェクト）を受け取らず、`dict`だけを受け取ります。

そのために`jsonable_encoder`を使用することができます。

Pydanticモデルのようなオブジェクトを受け取り、JSON互換版を返します:

# 配置 Swagger UI

你可以配置一些额外的 <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">Swagger UI 参数</a>.

如果需要配置它们，可以在创建 `FastAPI()` 应用对象时或调用 `get_swagger_ui_html()` 函数时传递 `swagger_ui_parameters` 参数。

`swagger_ui_parameters` 接受一个直接传递给 Swagger UI的字典，包含配置参数键值对。

FastAPI会将这些配置转换为 **JSON**，使其与 JavaScript 兼容，因为这是 Swagger UI 需要的。

## 不使用语法高亮

比如，你可以禁用 Swagger UI 中的语法高亮。
