如上文所述，这是 **FastAPI** 中使用的默认响应。

### `ORJSONResponse`

如上文所述，`ORJSONResponse` 是一个使用 <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a> 的快速的可选 JSON 响应。


### `UJSONResponse`

`UJSONResponse` 是一个使用 <a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a> 的可选 JSON 响应。

/// warning | "警告"

在处理某些边缘情况时，`ujson` 不如 Python 的内置实现那么谨慎。
