# 响应模型

你可以在任意的*路径操作*中使用 `response_model` 参数来声明用于响应的模型：

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* 等等。

{* ../../docs_src/response_model/tutorial001_py310.py hl[17,22,24:27] *}

/// note

注意，`response_model`是「装饰器」方法（`get`，`post` 等）的一个参数。不像之前的所有参数和请求体，它不属于*路径操作函数*。

///

它接收的类型与你将为 Pydantic 模型属性所声明的类型相同，因此它可以是一个 Pydantic 模型，但也可以是一个由 Pydantic 模型组成的 `list`，例如 `List[Item]`。

你也可以直接使用 `list` 代替 `List [str]`：

{* ../../docs_src/query_params_str_validations/tutorial013.py hl[7] *}

/// note

请记住，在这种情况下 FastAPI 将不会检查列表的内容。

例如，`List[int]` 将检查（并记录到文档）列表的内容必须是整数。但是单独的 `list` 不会。

///

## 声明更多元数据

你可以添加更多有关该参数的信息。

这些信息将包含在生成的 OpenAPI 模式中，并由文档用户界面和外部工具所使用。

/// note

请记住，不同的工具对 OpenAPI 的支持程度可能不同。

其中一些可能不会展示所有已声明的额外信息，尽管在大多数情况下，缺少的这部分功能已经计划进行开发。

Por ejemplo, para declarar un valor de metadato `title` para el parámetro de path `item_id` puedes escribir:

/// note | Nota

Un parámetro de path siempre es requerido ya que tiene que formar parte del path. Incluso si lo declaras con `None` o le asignas un valor por defecto, no afectará en nada, siempre será requerido.
