这些额外的信息将按原样添加到输出的JSON模式中。

## `Field` 的附加参数

在 `Field`, `Path`, `Query`, `Body` 和其他你之后将会看到的工厂函数，你可以为JSON 模式声明额外信息，你也可以通过给工厂函数传递其他的任意参数来给JSON 模式声明额外信息，比如增加 `example`:

{* ../../docs_src/schema_extra_example/tutorial002_py310.py hl[2,8:11] *}

/// warning

请记住，传递的那些额外参数不会添加任何验证，只会添加注释，用于文档的目的。

///

## `Body` 额外参数

你可以通过传递额外信息给 `Field` 同样的方式操作`Path`, `Query`, `Body`等。

        // Arrange
        SecurityBlob blob = new SecurityBlob(new byte[] { 1, 2, 3 });

        // Force internal field to null via reflection to exercise defensive branch
        Field field = SecurityBlob.class.getDeclaredField("b");
        field.setAccessible(true);
        field.set(blob, null);

        // Act & Assert
        assertEquals(0, blob.length(), "length() should return 0 when internal array is null");

Let's say you have a *path operation* with a path `/files/{file_path}`.

But you need `file_path` itself to contain a *path*, like `home/johndoe/myfile.txt`.

So, the URL for that file would be something like: `/files/home/johndoe/myfile.txt`.

### OpenAPI support { #openapi-support }

Imaginemos que tienes una *path operation* con un path `/files/{file_path}`.

Pero necesitas que `file_path` en sí mismo contenga un *path*, como `home/johndoe/myfile.txt`.

Entonces, la URL para ese archivo sería algo como: `/files/home/johndoe/myfile.txt`.
