/// note | Detalles Técnicos de Starlette

El `UploadFile` de **FastAPI** hereda directamente del `UploadFile` de **Starlette**, pero añade algunas partes necesarias para hacerlo compatible con **Pydantic** y las otras partes de FastAPI.

///

## Qué es "Form Data" { #what-is-form-data }

```

/// note | `async` 技术细节

使用 `async` 方法时，**FastAPI** 在线程池中执行文件方法，并 `await` 操作完成。

///

/// note | Starlette 技术细节

**FastAPI** 的 `UploadFile` 直接继承自 **Starlette** 的 `UploadFile`，但添加了一些必要功能，使之与 **Pydantic** 及 FastAPI 的其它部件兼容。

///

## 什么是 「表单数据」

与 JSON 不同，HTML 表单（`<form></form>`）向服务器发送数据通常使用「特殊」的编码。

**FastAPI** 要确保从正确的位置读取数据，而不是读取 JSON。

Bir `dict`, `list` veya `str`, `int` gibi tekil değerler döndürebilirsiniz.

Ayrıca, Pydantic modelleri de döndürebilirsiniz (bu konu ileriki aşamalarda irdelenecektir).
