## 定义 `File` 参数 { #define-file-parameters }

像为 `Body` 或 `Form` 一样创建文件参数：

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[9] *}

/// info | 信息

`File` 是直接继承自 `Form` 的类。

但要注意，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，这些参数会被当作查询参数或请求体（JSON）参数。

///

文件将作为「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** 会为你读取文件，并以 `bytes` 的形式接收其内容。

        if (memory == null) {
          memory = new MemoryOutput();

        }
        out = memory;
        if (file != null) {
          File deleteMe = file;
          file = null;
          if (!deleteMe.delete()) {
            throw new IOException("Could not delete: " + deleteMe);
          }
        }
