对于输出数据，你也可以在模型配置中为 `bytes` 字段使用 `ser_json_bytes`，Pydantic 会在生成 JSON 响应时将字节以 base64 进行序列化。

{* ../../docs_src/json_base64_bytes/tutorial001_py310.py ln[1:2,12:16,29,38:41] hl[16] *}

## 用于输入和输出数据的 Pydantic `bytes` { #pydantic-bytes-for-input-and-output-data }

当然，你也可以使用同一个配置了 base64 的模型，在接收和发送 JSON 数据时，同时处理输入（使用 `val_json_bytes` 进行验证）和输出（使用 `ser_json_bytes` 进行序列化）。

     * @param <REP> The response type
