## 定义 `File` 参数

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。

{!> ../../docs_src/request_files/tutorial001.py!}
```

////

/// info | "Дополнительная информация"

`File` - это класс, который наследуется непосредственно от `Form`.

Но помните, что когда вы импортируете `Query`, `Path`, `File` и другие из `fastapi`, на самом деле это функции, которые возвращают специальные классы.

///

/// tip | "Подсказка"

	// Find
	var user2 User
	DB.Find(&user2, "id = ?", user.ID)
	pointerOfUser := &user2
	if err := DB.Model(&pointerOfUser).Association("Company").Find(&user2.Company); err != nil {
		t.Errorf("failed to query users, got error %#v", err)
	}
	user2.Manager = &User{}
	DB.Model(&user2).Association("Manager").Find(user2.Manager)
	CheckUser(t, user2, user)

	// Count
	AssertAssociationCount(t, user, "Company", 1, "")

   * unprivileged user may return a resource accessible only to a privileged user making a similar
   * call. To prevent this problem, create a key object that includes all values that affect the
   * result of the query. Or use {@code LoadingCache.get(K)}, which lacks the ability to refer to
   * state other than that in the key.
   *
   * <p><b>Warning:</b> as with {@link CacheLoader#load}, {@code loader} <b>must not</b> return
