## 最佳化回應效能 - 回應模型 - 回傳型別 { #optimize-response-performance-response-model-return-type }

為了在回傳 JSON 資料時最佳化效能，請使用回傳型別或回應模型，如此 Pydantic 會在 Rust 端處理序列化為 JSON，而不經過 Python。更多內容請參閱[教學 - 回應模型 - 回傳型別](../tutorial/response-model.md)。

# 表单数据 { #form-data }

当你需要接收表单字段而不是 JSON 时，可以使用 `Form`。

/// info

要使用表单，首先安装 [`python-multipart`](https://github.com/Kludex/python-multipart)。

请先创建并激活一个[虚拟环境](../virtual-environments.md)，然后再进行安装，例如：

```console
$ pip install python-multipart
```

///

## 导入 `Form` { #import-form }

从 `fastapi` 导入 `Form`：

            data = hostname.toCharArray();
