And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

**FastAPI** will use that *temporal* response to extract the status code (also cookies and headers), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

回到之前的代码示例，**FastAPI** 将会：

* 校验 `GET` 和 `PUT` 请求的路径中是否包含 `item_id`。
* 校验 `GET` 和 `PUT` 请求中的 `item_id` 是否为 `int` 类型。
    * 如果不是，客户端会看到清晰有用的错误信息。
* 对于 `GET` 请求，检查是否存在名为 `q` 的可选查询参数（如 `http://127.0.0.1:8000/items/foo?q=somequery`）。
    * 因为参数 `q` 被声明为 `= None`，所以它是可选的。
    * 如果没有 `None`，它就是必需的（就像 `PUT` 情况下的请求体）。
* 对于发送到 `/items/{item_id}` 的 `PUT` 请求，把请求体作为 JSON 读取：
    * 检查是否存在必需属性 `name`，且为 `str`。
