## `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。

比如，你可以将请求体的一个 `example` 传递给 `Body`:

 * should override one or more methods to modify the behavior of the backing executor service as
 * desired per the <a href="http://en.wikipedia.org/wiki/Decorator_pattern">decorator pattern</a>.
 *
 * <p><b>{@code default} method warning:</b> This class does <i>not</i> forward calls to {@code
 * default} methods. Instead, it inherits their default implementations. When those implementations
 * invoke methods, they invoke methods on the {@code ForwardingExecutorService}.
