创建文件（`File`）参数的方式与 `Body` 和 `Form` 一样：

```Python hl_lines="7"
{!../../docs_src/request_files/tutorial001.py!}
```

/// info | "说明"

`File` 是直接继承自 `Form` 的类。

注意，从 `fastapi` 导入的 `Query`、`Path`、`File` 等项，实际上是返回特定类的函数。

///

/// tip | "提示"

声明文件体必须使用 `File`，否则，FastAPI 会把该参数当作查询参数或请求体（JSON）参数。

///

文件作为「表单数据」上传。

如果把*路径操作函数*参数的类型声明为 `bytes`，**FastAPI** 将以 `bytes` 形式读取和接收文件内容。

/// info

`File` ist eine Klasse, die direkt von `Form` erbt.

Aber erinnern Sie sich, dass, wenn Sie `Query`, `Path`,  `File` und andere von `fastapi` importieren, diese tatsächlich Funktionen sind, welche spezielle Klassen zurückgeben
